LIGHT EMITTING DIODE (LED) LIGHTING DEVICE OR LAMP
WITH CONFIGURABLE LIGHT QUALITIES
BACKGROUND
Incandescent bulbs are slowly being phased out in favor of more efficient
lighting
sources. This has led to an increased use of compact fluorescent bulbs which
are more
efficient than incandescent bulbs, but which tend to contain dangerous gasses,
such as
mercury. Compact fluorescent bulbs are also affected by ambient temperature
and fail reach
their peak brightness in colder conditions. Additionally, many people find the
color
temperature of light emitted by compact fluorescents to not be aesthetically
pleasing for
many applications, such as household lighting in kitchens, bathrooms, and
living rooms;
some commercial applications; and the like. Due to the nature of compact
fluorescent bulbs,
the bulbs always have a frosted appearance, which also tends to reduce the
aesthetic appeal
of compact fluorescent bulbs. The use of halogen bulbs has also increased;
however due to
the high temperatures at which halogen bulbs operate they are not highly
efficient and may
be a fire or burn hazard.
Recent advances in manufacturing light emitting diodes (LEDs) combined with
the
efficiency and long lifetime of LEDs have led to an increase in the
availability and
affordability of LED lamps and other LED lighting devices. LED lamps and
lighting
devices offer advantages over compact fluorescent bulbs including longer
lifetime and the
absence of dangerous gasses. Also, LED lamps and lighting devices may be
configured to
emit light at a wide variety of color temperatures.
Therefore, there is a need in the art for LED lighting devices that allow
users to take
advantage of the wide variety of color temperatures at which LEDs may emit
light.

DETAILED DESCRIPTION OF VARIOUS EMBODIMENTS
The present invention now will be described more fully hereinafter with
reference
to the accompanying drawings, in which some, but not all embodiments of the
invention are
shown. Indeed, the invention may be embodied in many different forms and
should not be
construed as limited to the embodiments set forth herein; rather, these
embodiments are
provided so that this disclosure will satisfy applicable legal requirements.
Like numbers
refer to like elements throughout.
Example embodiments of the present invention provide an LED lamp or LED
lighting device having two or more user selectable modes. Switching between
modes may
adjust one or more aspects or qualities of the light provided by the LED lamp
or LED
lighting device when the LED lamp or LED lighting device is operating. For
example,
switching between modes may adjust the quality of the light provided by the
LED lamp or
LED lighting device when the LED lamp or LED lighting device is operating. For
example,
switching between modes may adjust the brightness, color rendering index
(CRI), color
temperature, and/or the like of the light emitted by the LED lamp or LED
lighting device
when the LED lamp or LED lighting device is operating.
Example embodiments of the present invention described herein generally relate
to
an LED lamp or LED lighting device wherein the operating light aspects or
qualities (e.g.,
brightness, color temperature, CRI, and/or the like of the light emitted by
the LED lamp or
LED lighting device when the LED lamp or LED lighting device is being operated
and/or
is turned on), is selectively configurable. For example, example embodiments
of the present
6
CA 3021693 2018-10-22
invention described herein generally relate to an LED lamp or LED lighting
device wherein
the operating color temperature (e.g., the color temperature of the light
emitted by the LED
lamp or LED lighting device when the LED lamp or LED lighting device is being
operated
and/or is turned on), is selectively configurable. However, it should be
understood that
principles of the present invention may be used to provide an LED lamp or LED
lighting
device for which one or more aspects or qualities of the light provided during
operation of
the LED lamp or LED lighting device may be modified through selection of a
particular
mode. Examples of the aspects that may be modified through mode selection may
include,
but are not limited to, brightness, CRI, color temperature, and/or
combinations thereof.
For example, a user may select a desired operating light aspects or qualities
(e.g.,
color temperature, brightness, CRI, and/or the like, and/or a combination
thereof) for the
LED lamp or LED lighting device before the LED lamp or LED lighting device is
installed.
Alternatively, the user may select to operate the LED lamp or LED lighting
device in a
configurable operating mode following installation. For example, the LED lamp
or LED
lighting device may be operated in a configurable mode that allows a user to
change one or
more of the operating light aspects or qualities during operation of the LED
lamp or LED
lighting device using a remote switch. In example embodiments, a remote switch
may be a
wall mounted switch mounted in the same room as the LED lamp or LED lighting
device
and/or within a short range communication technology range of the LED lamp or
LED
lighting device. In another example, the remote switch may be a handheld
device (e.g., a
remote control), computing entity, and/or the like, that is within the same
room as the LED
lamp or LED lighting device, within a short range communication technology
range of the
LED lamp or LED lighting device, and/or in communication with the LED lamp or
LED
lighting device through a wired and/or wireless network.
As noted above, LEDs may be manufactured that emit light at a variety of color
temperatures. Moreover, LEDs may be configured to emit light at a variety of
brightness,
CRI, and/or having other configurable light aspects or qualities. Embodiments
of the present
invention allow a user to take advantage of the variety of light aspects or
qualities at which
LEDs may emit light by allowing the user to operate an LED lamp or LED
lighting device
at a selectable mode such that the user may select and/or modify aspects or
qualities of the
emitted light. For example, embodiments of the present invention allow a user
to take
advantage of the variety of color temperatures at which LEDs may emit light by
allowing
the user to operate an LED lamp or LED lighting device at a selectable
configurable
operating color temperature. For example, the user may be able to change the
operating
7
CA 3021693 2018-10-22
color temperature of the LED lamp or LED lighting device as the user desires
during the
operation of the LED lamp or LED lighting device. The user may also choose to
select a
programmable operating color temperature for the LED lamp or LED lighting
device. For
example, the LED lighting device or LED lamp may be programmed to a set
operating color
temperature mode in which the operating color temperature cannot be changed
during
operation of the LED lamp or LED lighting device. Thus, embodiments of the
present
invention allow a user to take advantage of the wide range of color
temperatures at which
LEDs may produce light.
For example, given the wide array of color temperatures and other light
aspects or
qualities (e.g., brightness, CRE, etc.) available in LED lamps and LED
lighting devices,
retailers need to stock a variety of different color temperature, brightness,
and/or other light
aspect or quality options for each style of LED lamp and/or LED lighting
device to provide
consumers with the options the consumer's desire. Moreover, it is common in
multiple
purpose rooms (e.g., family rooms, etc.) that different lighting options may
be desired. For
example, a light having an operating color temperature of 5000k may be desired
if a user is
sitting on the couch reading, but the user may prefer a light having an
operating color
temperature of 3000K when watching television. Traditionally this would
require the user
to have two lighting options available in the same room. However, example
embodiments
of the present invention allow the user to have a light source of operating
temperature of
3000K and a light source of operating temperature of 5000K while only
requiring one
lighting device. Similarly, with example embodiments of the present invention,
retailers
need only to stock LED lamps and/or LED lighting devices based on the style of
the lamp
and/or lighting device as the operating color temperature and/or other light
aspects or
qualities of the lamp and/or lighting device are selectable.
In example embodiments, the LED lamp 10 or LED lighting device 20 allows a
user
to select an operating mode (e.g., a programmable custom mode, a set mode, or
a
configurable mode). One or more qualities of the light (e.g., color
temperature, brightness,
CRI, and/or the like) emitted by the LED lamp 10 and/or LED lighting device 20
may then
be controlled based on the user-selected operating mode. One or more qualities
of the light
emitted by the LED lamp 10 and/or LED lighting device 20 may be modified
through mode
switching (e.g., using switch 30) and/or configured using a remote switch 40
when the user-
selected mode is a configurable mode.
In an example embodiment, the LED lamp 10 or LED lighting device 20 allows a
user to select between one or more non-adjustment modes in which the user may
select the
8
CA 3021693 2018-10-22
operating qualities of the light emitted by the LED lamp 10 or LED lighting
device 20 and
one or more sensor adjustment modes in which the user may select goal light
qualities for a
space that the LED lamp 10 or LED lighting device 20 is located in. In various
embodiment,
the non-adjustment mode(s) and/or sensor adjustment mode(s) may be set
operating modes
and/or configurable operating modes. In an example embodiment, the LED lamp 10
or LED
lighting device 20 may be in communication with one or more sensors (e.g.,
light sensor,
photocell, motion sensor), and, when the LED lamp 10 or LED lighting device 20
is in a
sensor adjustment mode, the operating qualities of the LED lamp 10 or LED
lighting device
20 may be adjusted and/or modified based on sensor signals received from the
one or more
sensors.

may comprise
a switch 30 in electrical communication with a switch control unit 35. The
switch control
unit 35 may be in electrical communication with the driver circuitry 19. In an
example
embodiment, the switch control unit 35 may be in electrical communication with
a driver
integrated circuit (IC) 19a configured to control, condition, configure and/or
the like the
electrical current provided to one or more LED packages 18. The driver

temperature provided each is different relative to one another
In example embodiments, the two or more LED packages 18 may be in electrical
communication with driver circuitry 19 such that the two or more LED packages
18 may be
operated by the driver circuitry 19. For example, the driver circuitry 19 may
provide a
controlled electrical current to at least one of the LED packages I 8. For
example, the driver
circuitry 19 may be configured to only operate first LED packages 18a to cause
the LED
lamp 10 or LED lighting device 20 to emit light of the first color
temperature. In another
example, the driver circuitry 19 may be configured to only operate second LED
packages
18b to cause the LED lamp 10 or LED lighting device 20 to emit light of the
second color
temperature. In another example, the driver circuitry 19 may be configured to
operate one
or more (e.g., half) of the first LED packages 18a and one or more (e.g.,
half) of the second
LED packages 18b to cause the LED lamp 10 or LED lighting device 20 to emit
light of a
third color temperature. In example embodiments, the first color temperature,
second color
temperature, and third color temperature may be different from one another.
For example,
the first color temperature may be 3000K, the second color temperature may be
5000K, and
the third color temperature may be 4000K. In some embodiments, the LED lamp 10
or LED
12
CA 3021693 2018-10-22
lighting device 20 may comprise LED packages 18 configured to emit light at
more than
two distinct color temperatures (e.g., three, four, or more distinct color
temperatures).
In example embodiments, the one or more LED packages 18 may be configured to
provide light that varies in brightness, color temperature, CRI, and/or the
like based on the
current provided to the one or more LED packages 18 by the driver circuitry
19. For
example, the driver circuitry may provide a particular current to an LED
package 18 to cause
the LED package 18 to provide light having particular light aspects or
qualities.
In example embodiments, the LED packages 18 may comprise one or more LED
packages 18 that are configured to emit light other than "white" light. For
example, the LED
packages 18 may comprise one or more LED packages 18 configured to emit a red
or amber
light that may be operated to increase the CRI of the light emitted by the LED
lamp 10 or
LED lighting device 20.
Example Driver Circuitry
In example embodiments, the driver circuitry 19 may be configured to provide a
controlled electrical current to at least one of the LED packages 18 during
operation of the
LED lighting device 20 or LED lamp 10. In various embodiments, the driver
circuitry 19
may comprise a circuit portion configured to convert AC voltage into DC
voltage. In some
embodiments, the driver circuitry 19 may comprise a circuit portion configured
to control
the current flowing through the two or more LED packages 18. In certain
embodiments, the
driver circuitry 19 may comprise a circuit portion configured to dim the LED
lamp 10 or
LED lighting fixture 20. In various embodiments, additional circuit components
may be
present in the driver circuitry 19. Similarly, in various embodiments, all or
some of the
circuit portions mentioned here may not be present in the driver circuitry 19.
In some
embodiments, circuit portions listed herein as separate circuit portions may
be combined
into one circuit portion. As should
be appreciated, a variety of driver circuitry
configurations are generally known and understood in the art and any of such
may be
employed in various embodiments as suitable for the intended application,
without departing
from the scope of the present invention.
In example embodiments, the driver circuitry 19 may be configured to operate
subsets of the two or more LED packages 18 at a particular given moment in
time. For
example, if a first color temperature has been selected by a user as the
operating color
temperature, the driver circuitry 19 may be configured to operate one or more
first LED
packages 18a configured to emit light at the selected first color temperature.
If a second
13
CA 3021693 2018-10-22
color temperature has been selected by the user as the operating color
temperature, the driver
circuitry 19 may be configured to operate one or more second LED packages 18b
configured
to emit light at the second selected color temperature. If a third color
temperature has been
selected by the user as the operating color temperature, the driver circuitry
19 may be
configured to operate at least a portion of the first LED packages 18a (e.g.,
half of the first
LED packages 18a) and at least a portion of the second LED packages 18b (e.g.,
half of the
second LED packages 18b) to provide (e.g., via a combination of the first and
second LED
packages) a selected third color temperature that is a composite, mixture, or
superposition
of the first and second color temperatures. The selection of which LED
packages 18 are
operated by the driver circuitry 19, when the LED lamp 10 or LED lighting
device 20 is
operated, is determined by the status of the switch 30 and/or by the switch
control unit 35.
For example, the driver circuitry 19 may comprise a plurality of provider
circuits 17
configured to provide a controlled electrical current to a subset of the two
or more LED
packages 18 depending on the selected operating color temperature and/or the
status of the
switch 30.
In another example, the driver circuitry 19 may be configured to provide a
particular
current to one or more of the LED packages 18 to provide light having specific
light aspects
qualities (e.g., brightness, color temperature, CRI, and/or the like). For
example, the driver
circuitry 19 may be configured to drive one or more LED packages 18 such that
the LED
packages provide light having the desired light aspects or qualities. The
determination of
how one or more of the LED packages 18 should be driven (e.g., what current
should be
supplied to the LED packages 18) may be determined by the status of the switch
30 and/or
by the switch control unit 35. Based on the desired light aspects or
qualities, different LED
packages 18 may be driven differently. For example, LED packages 18 may be
driven
differently from a red or amber LED package 18 that is being operated to
increase the CR1
of the light emitted by the LED lamp 10 or LED lighting device 20. Thus, the
provider
circuits 17 may be configured to provide various LED packages 18 with a
particular
configurable current such that the composite light emitted by the LED lamp 10
or LED
lighting device 20 has the user desired light aspects or qualities.
For example, in an example embodiment (with reference to Figure 4) that allows
a
user to choose between three different operating color temperature options,
the driver
circuitry 19 may comprise three distinct provider circuits 17 for providing
the controlled
electrical current to the at least one of the two or more LED packages 18 for
operation. For
example, the switch control unit 35 and/or the position of the switch selector
34 may
14
CA 3021693 2018-10-22
determine which provider circuit 17 is used during the operation of the LED
lamp 10 or
LED lighting device 20. Generally, only one of the provider circuits 17 is in
use at a given
time. For example, a first provider circuit 17 may be configured to provide
electrical current
to one or more first LED packages 18a when the selected operating color
temperature is the
first color temperature, a second provider circuit 17 may be configured to
provide electrical
current to one or more second LED packages 18b when the selected operating
color
temperature is the second color temperature, and a third provider circuit 17
may be
configured to provide electrical current to at least one first LED package 18a
and at least
one second LED package 18b when the selected operating color temperature is
the third
color temperature. The selection of the operating color temperature may be
based at least in
part on the status of a switch 30 (e.g., the position of the switch selector
34) and/or by a
switch controller unit 35.
In example embodiments, various configurations of provider circuits 17 may be
applied. For example, as noted above, a provider circuit 17 may be configured
to provide
electrical current to only the first LED packages 18a, only the second LED
packages 18b,
or a predetermined combination of the first and second LED packages 18a and
18b. For
example, a provider circuit 17 may be configured to provide electrical current
to half of the
first LED packages 18a and half of the second LED packages 18b to provide
light of the
third color temperature. In another example, a provider circuit 17 may be
configured to
provide electrical current to 25% of the first LED packages 18a and 75% of the
second LED
packages 18b to provide light of a fourth color temperature. It should be
understood that a
provider circuit 17 may be configured to provide controlled electrical current
to various
combinations of the first LED packages 18a and the second LED packages 18b to
provide
various color temperature options. Furthermore, in example embodiments, the
two or more
LED packages 18 may comprise three or more LED packages 18. For example, the
LED
packages 18 may comprise at least one first LED package 18a configured to emit
light at a
first color temperature, at least one second LED package 18b configured to
emit light at a
second color temperature, and at least one third LED package configured to
emit light at a
third color temperature, the first, second, and third color temperatures being
different from
one another. In such an embodiment, a provider circuit 17 may be configured to
provide
electrical current to at least one of the first LED packages 18a, at least one
of the second
LED packages 18b, and at least one of the third LED packages to provide a
three color
blend. It should be understood that LED packages configured to emit light at
additional
color temperatures may be incorporated into the LED lamp 10 or LED lighting
device 20 as
CA 3021693 2018-10-22
desired and/or appropriate for the application and that various combinations
of the LED
packages may be activated to cause the LED lamp 10 or LED lighting device 20
to emit
light of a desired operating color temperature.
As noted above, the light aspects or qualities (e.g., brightness, color
temperature,
CRI, and/or the like) may be controlled by how the one or more LED packages 18
are
operated (instead of and/or in addition to which of the LED packages 18 are
operated). In
example embodiments, one or more configurable qualities of the light emitted
by the LED
lamp 10 or the LED lighting device 20 may configured by controlling the
current provided
to one or more of the LED packages 18. In particular, the driver circuitry 19
may drive the
one or more LED packages 18 with a higher or lower current to modify the
brightness, color
temperature, CRI, and/or the like of the light emitted by the one or more LED
packages 18.
In another example, the driver circuitry 19 may increase or decrease the
number of LED
packages 18 being driven to increase or decrease the brightness of the light
emitted by the
LED lamp 10 or the LED lighting device 20. In another example, one or more red
or amber
LED packages 18 may be turned on (e.g., electrical current may be supplied
thereto by the
driver circuitry 19) to increase the CRI of the light emitted by the LED lamp
10 or LED
lighting device 20. In another example, the primary or secondary optics used
to condition
the light emitted by the LED lamp 10 or LED lighting device 20. For example,
the optics 13
may be modified, the amount of phosphor through which an LED is emitting may
be
modified, and/or the like. Thus, in example embodiments, one or more qualities
of the light
emitted by the LED lamp 10 or LED lighting device 20 may be modified,
controlled,
configured, and/or the like by changing and/or controlling the amount of
current provided
to one or more LED packages 18, which LED packages 18 of the two or more LED
packages
18 are being operated, physically changing the primary and/or secondary optics
conditioning
the light, and/or the like. Thus, for example in an embodiment configured to
provide
configurable brightness settings or modes, the dimming of the LED lamp 10 or
LED lighting
device 20 may be controlled by the switch control unit 35 and/or driver
circuitry 19 rather
than by the externally provided current.
In example embodiments, when the LED lamp 10 or LED lighting device 20 is in a
configurable operating mode, interaction with the remote switch 40 (e.g.,
reception of a
signal from the remote switch 40) may cause the topology of the driver
circuitry to be
altered. For example, user interaction with the remote switch 40 may cause a
signal to be
provided to the switch control unit 35. The switch control unit 35 may then
cause a change
in the topology of the driver circuitry 19, thereby causing the driver
circuitry 19 to operate
16
CA 3021693 2018-10-22
a different set of LED packages 18, drive one or more LED packages 18 with a
modified
current, and/or the like.
Example Switch
In example embodiments, the LED lamp 10 and/or LED lighting device 20
comprises a switch 30. In example embodiments, the switch 30 may be configured
to allow
a user to select an operating mode (e.g., a programmable custom mode, a set
mode, or a
configurable mode). One or more aspects or qualities of the light (e.g., color
temperature,
brightness, CRI, and/or the like) emitted by the LED lamp 10 and/or LED
lighting device
20 may then be controlled based on the user-selected operating mode. In
example
embodiments, the switch 30 may be a mechanical switch, electro-mechanical
switch, an
infrared switch, and/or the like. For example, if the switch 30 is a
mechanical switch, the
switch 30 may comprise a slide switch, a dial, a set of binary switches,
and/or the like. In an
example embodiments, the switch 30, and/or a user interface thereof, may be
disposed on
an exterior surface of the lamp housing 14 or the device housing 24. Figures 3
and 3A
provide block diagrams of at least some of the electrical components of an LED
lamp 10 or
LED lighting device 20, including a switch 30 and a switch control unit 35, in
accordance
with example embodiments of the present invention. In example embodiments, the
switch
30 may comprise a plurality of switch positions 32 (e.g., 32a, 32b, 32c, 32d),
switch position
indicators 33 (e.g., 33a, 33b, 33c, 33d), and a switch selector 34. For
example, the switch
30 may comprise four switch positions 32a, 32b, 32c, and 32d, in example
embodiments. In
other embodiments, the switch 30 may comprise more than four switch positions
32 (e.g.,
32a, 32b, 32e, 32d). For example, in various embodiments, the switch 30 may
comprise two,
three, four, five, six, seven, eight, or more switch positions with each
switch position
corresponding to either a set operating mode, a selectively configurable
operating mode, or
a programmable custom operating mode. One of the switch positions may
correspond to a
configurable operating mode (e.g., a configurable operating color temperature
mode,
configurable brightness mode, configurable brightness-color temperature mode,
etc.) and
the remaining switch positions may correspond to set operating modes (e.g.,
set operating
color temperature modes, set brightness modes, set operating brightness-color
temperature
modes, etc.) wherein the different switch positions select the particular set
light aspects or
qualities (e.g., brightness, operating color temperature, CRI, and/or the
like). For example,
switch positions 32a, 32b, and 32c may correspond to set operating color
temperature modes
17
CA 3021693 2018-10-22
with each position corresponding to a particular set operating color
temperature. The switch
position 32d may correspond to a configurable operating color temperature
mode.
In some embodiments, the switch 30 may provide the user with one or more
programmable custom operating modes. In an example embodiment, the switch 30
may
comprise a custom set operating color temperature mode, in which a user may
define and/or
select a pre-defined mixture of the first, second, third, and/or the like
operating color
temperatures such that the LED lamp 10 or LED lighting device 20 provides a
light at the
custom set operating color temperature. In another example, the switch 30 may
comprise a
custom program operating brightness-color temperature operating mode such that
the LED
lamp 10 or LED lighting device 20 provides light at a custom set operating
color temperature
at a set brightness. In another example, the switch 30 may comprise a custom
program
operating mode wherein the switch control unit 35 is configured to cause the
operating color
temperature, brightness, and/or CRI to change at configurable times (e.g.,
clock time) or at
configurable periods of time. For example, a user may wish to have the LED
lamp 10 or
LED lighting device 20 operate at one operating color temperature during the
morning
hours, another operating color temperature during the afternoon, and another
operating color
temperature in the evening or night time hours. In another example, a user may
want the
LED lamp 10 or LED lighting device 20 to operate at one operating color
temperature,
brightness, and/or CRI for the first twenty minutes the LED lamp 10 or LED
lighting device
20 is operating and then to operate at another operating color temperature,
brightness, and/or
CRI for the next three hours or for as long as the LED lamp 10 or LED lighting
device 20
remains in constant operation. In example embodiments having programmable
custom
operating mode options, additional user interface components (e.g., in
addition to the switch
30) may be provided for the programming of the programmable custom operating
mode.
The additional user interface components may be located on the housing 14, 24
of the LED
lamp 10 or LED lighting device 20 and/or on a remote switch 40 (e.g., through
a mobile
computing entity 40' user interface, wherein the computing entity 40' is
executing an
application causing the computing entity 40' to operate as a remote switch
40). In example
embodiments, such additional user interface components may comprise various
switches,
dials, displays, touchscreen displays, buttons, knobs, and/or the like as
commonly
understood in the art.
A switch position indicator 33 (e.g., 33a, 33b, 33c, 33d) may correspond to
each
switch position 32 (e.g., 32a, 32b, 32c, 32d). The switch position indicator
33 (e.g., 33a,
33b, 33c, 33d) may be configured to indicate the operating mode (e.g., color
temperature
18
CA 3021693 2018-10-22
and/or option or mode, etc.) selected by placing the switch selector 34 in the
corresponding
switch position. For example, switch position indicator 33a may show
approximately where
the switch position 32a is located and may indicate the color temperature
and/or option or
mode selected by placing the switch selector 34 in switch position 32a. For
example, the
switch position indicator 33a indicates that if the switch selector 34 is
placed in the switch
position 32a, a set operating color temperature mode is selected with the set
operating color
temperature being 3000K. Similarly, the switch position indicator 33b
indicates that if the
switch selector 34 is placed in the switch position 32b, a set operating color
temperature
mode is selected with the set operating color temperature being 4000K; the
switch position
indicator 33c indicates that if the switch selector 34 is placed in the switch
position 32e, a
set operating color temperature mode is selected with the set operating color
temperature
being 5000K; and the switch position indicator 33d indicates that if the
switch selector 34
is placed in the switch position 32d, the configurable operating color
temperature mode is
selected. For example, if the switch selector 34 is placed in switch position
34d, the
operating color temperature of the LED lamp 10 or LED lighting device 20 may
be
configurable by using a wall switch, remote control, and/or the like (e.g.,
remote switch 40
shown in Figure 5). In another example, as shown in Figure 4A, the switch
position indicator
33a indicates that if the switch selector 34 is placed in the switch position
32a, a set operating
mode is selected with the set light aspects or qualities being A; the switch
position indicator
33b indicates that if the switch selector 34 is placed in the switch position
32b, a set
operating mode is selected with the set light aspects or qualities being B;
the switch position
indicator 33c indicates that if the switch selector 34 is placed in the switch
position 32c, a
set operating mode is selected with the set light aspects or qualities being
C; and the switch
position indicator 33d indicates that if the switch selector 34 is placed in
the switch position
32d, the configurable operating is selected wherein a user may use a remote
switch 40 to
toggle between A, B, and C, wherein A, B, and C may be operating states of any
preset color
temperature, brightness, CRI, and/or the like, provided each operating state
is different in at
least one light aspect or quality relative to one another. The status of the
switch 30 is
determined by the switch position 32 (e.g. 32a, 32b, 32c, 32d) in which the
switch selector
34 is positioned. The switch 30 has been illustrated herein as slider switch.
It should be
understood however, that the switch 30 may take a variety of forms as
appropriate for the
application. For example, Figure 2E illustrates an example switch 30 having a
multiple
position pivot switch selector 34' having switch positions that are selected
based on the
angle of the pivot switch selector 34'.
19
CA 3021693 2018-10-22
In example embodiments, a user may change the operating light aspects or
qualities
(e.g., operating color temperature, brightness, CRI, and/or the like) of the
LED lamp 10 or
LED lighting device 20 by changing the positions of the switch selector 34.
For example, in
various embodiments, the user may change the position of the switch selector
34 while the
LED lamp 10 or LED lighting device 20 before installation of the LED lamp 10
or LED
lighting device 20, after installation of the LED lamp 10 or LED lighting
device 20 but when
the LED lamp 10 or LED lighting device 20 is not in use (e.g., is turned off
and not emitting
light), or while the LED lamp 10 or LED lighting device 20 is in use (e.g., is
turned on and
is emitting light). In example embodiments, if the position of the switch
selector 34 is
changed while the LED lamp 10 or LED lighting device 20 is in use, causing the
light
aspects or qualities thereof to change, the change of the light aspects or
qualities may occur
within two seconds of the position of the switch selector 34 being changed.
In an example embodiment, a user-selection switch 31 (e.g., a toggle switch,
button,
and/or the like) may be disposed on the LED lamp 10 or LED lighting device 20
such that
user-selection may be received through user-selection switch at the LED lamp
10 or LED
lighting device 20. Thus, the user may change the operating light aspects or
qualities of the
LED lamp 10 or LED lighting device 20 when the LED lamp 10 or LED lighting
device 20
is in a configurable operating mode by interacting with the user-selection
switch 31 rather
than by using the remote switch 40.
In an example embodiment, the LED lamp 10 or LED lighting device 20 comprises
two switches 30. For example, a first switch 30 may correspond to one or more
set or
configurable operating modes and a second switch 30 may correspond to whether
the LED
lamp 10 or LED lighting device 20 is a sensor adjustment mode or non-
adjustment mode.
In another example embodiment, only one switch 30 is provided an each
selectable position
of the switch 30 selects an operating mode that is either a set operating mode
or a
configurable operating mode and either a sensor adjustment mode or a non-
adjustment
mode.
Example Switch Control Unit
In example embodiments, the LED lamp 10 or LED lighting device 20 may comprise
a switch control unit 35. In example embodiments, the switch control unit 35
may be
configured to cause the driver circuitry 19 to operate one or more LED
packages 18 in
accordance with the user-selected operating mode (e.g., a programmable custom
mode, a
set mode, or a configurable mode). In example embodiments, the switch control
unit 35 may
CA 3021693 2018-10-22
be a microcontroller unit (MCU). For example, the switch control unit 35 may
comprise a
single integrated circuit. In example embodiments, the switch control unit 35
comprises one
or more processing elements 37, one or more memory elements 36, and/or one or
more
communication interface elements 38. In example embodiments, the switch
control unit 35
may be in wired (e.g., hard-wired) communication with the switch 30 and/or
configured to
receive signals from the remote switch 40. In example embodiments, the switch
control unit
35 may be configured to cause one or more operating light aspects or qualities
(e.g.,
operating color temperature, brightness, CRI) of the LED lamp 10 or the LED
lighting
device 20 to be modified based on a received signal from the remote switch 40,
store
information/data identifying the last light aspects or qualities at which the
LED lamp 10 or
the LED lighting device 20 was operated at, and/or the like. For example, the
switch control
unit 35 may be configured to receive user selection of a programmable custom
operating
mode and control the LED lamp 10 or the LED lighting device 20 to operate in
accordance
with the programmable custom operating mode or other user-selected operating
mode (e.g.,
set operating mode or configurable operating mode).
In example embodiments, the one or more processing elements 37 (also referred
to
as processors, processing circuitry, processing device, and/or similar terms
used herein
interchangeably) that communicate with other elements within the switch
control unit 35.
For example, the processing element(s) 37 may communicate with the memory
element(s)
36, communication interface element(s) 38, and/or components of the driver
circuitry 19 via
direct electrical connection, a bus, and/or the like. For example, the
processing element(s)
37 may be configured to process input received through the switch 30 (and/or
additional
user interface components), process a signal received from the remote switch
40 (e.g.,
through the communication interface clement 38), cause the memory element 36
to store a
current operating color temperature, cause one provider circuit 17 to be
activated (e.g., to
provide a controlled electric current to the corresponding at least one LED
package 18),
cause another provider circuit 17 to be de-activated (e.g., to stop providing
an electric
current to the corresponding at least one LED package 18), cause a different
and/or modified
current to be provided to the provider circuit 17 (e.g., such that the LED
package 18 is driven
in a modified manner by the provider circuit 17) and/or the like. As will be
understood, the
processing element 37 may be embodied in a number of different ways. For
example, the
processing element 37 may be embodied as one or more complex programmable
logic
devices (CPLDs), microprocessors, multi-core processors, co-processing
entities,
application-specific instruction-set processors (A SIPs), m
icrocontro 1 lers, and/or
21
CA 3021693 2018-10-22
controllers. Further, the processing element 37 may be embodied as one or more
other
processing devices or circuitry. The term circuitry may refer to an entirely
hardware
embodiment or a combination of hardware and computer program products. Thus,
the
processing element 37 may be embodied as integrated circuits, application
specific
integrated circuits (ASICs), field programmable gate arrays (FPGAs),
programmable logic
arrays (PLAs), hardware accelerators, other circuitry, and/or the like. As
will therefore be
understood, the processing clement 37 may be configured for a particular use
or configured
to execute instructions stored in volatile or non-volatile media or otherwise
accessible to the
processing element 37. As such, whether configured by hardware or computer
program
products, or by a combination thereof, the processing element 37 may be
capable of
performing steps or operations according to embodiments of the present
invention when
configured accordingly.
The memory element(s) 36 may be non-transitory and may include, for example,
one or more volatile and/or non-volatile memories. In other words, for
example, the
memory element 36 may be an electronic storage device (e.g., a computer
readable storage
medium) comprising gates configured to store data (e.g., bits) that may be
retrievable by a
machine (e.g., a computing device like the processing element 37). The memory
element
36 may be configured to store information, data, content, applications,
instructions, or the
like for enabling the switch control unit 35 to carry out various functions in
accordance with
an example embodiment of the present invention. For example, the memory
element 35
could be configured to buffer input data for processing by the processing
element 37 (e.g.,
a signal received from the remote switch 40). In example embodiments, the
memory element
36 may be configured to store a most recent operating light aspects or
qualities (e.g., color
temperature, brightness, CRI, and/or the like, and/or combination thereof).
Additionally or
alternatively, the memory element 36 could be configured to store instructions
for execution
by the processing element 37.
As indicated, in one embodiment, the switch control unit 35 may also include
one or
more communications interface elements 38 for communicating with the remote
switch 40.
For example, the communications interface element 38 may be configured to
receive a
signal from the remote switch 40 indicating user selection of, activation of,
and/or
interaction with an on/off or power button, a dimmer switch, or a remote
selector switch
configured to select or modify the operating color temperature of the LED lamp
10 or LED
lighting device 20, and/or the like. Such communication may be executed using
a wired
data transmission protocol, such as fiber distributed data interface (FDDI),
digital subscriber
22
CA 3021693 2018-10-22
line (DSL), Ethernet, asynchronous transfer mode (ATM), frame relay, data over
cable
service interface specification (DOCSIS), or any other wired transmission
protocol.
Similarly, the communications interface element 38 may be configured to
communicate via
a wireless communication technology, such as a short range communication
technology.
For example, the communications interface element 38 may be configured to
receive and/or
send signals using IEEE 802.11 (Wi-Fi), Wi-Fi Direct, 802.16 (WiMAX), ultra
wideband
(UWB), infrared (ER) protocols, near field communication (NFC) protocols,
Wibrec,
Bluetooth protocols, wireless universal serial bus (USB) protocols, and/or any
other wireless
protocol.
In example embodiments, the switch control unit 35 may be configured to cause
the
LED lamp 10 or LED lighting device 20 to operate at the operating color
temperature,
brightness, CRI, and/or other particular light aspect or quality, when the LED
lamp 10 or
LED lighting device 20 is turned on. For example, the switch control unit 35
may be
configured to determine the status of the switch 30 and operate the LED lamp
10 or LED
lighting device 20 accordingly. For example, the switch control unit 35 may be
configured
to determine if the position of the switch selector 34 is a position
corresponding to a set
operating mode, to the position corresponding to the configurable operating
mode, and/or
to a position corresponding to a programmable custom operating mode. If the
switch selector
34 is in a switch position 32 (e.g., 32a, 32b, 32c) corresponding to a set
operating mode, the
switch control unit 35 (e.g., the processing element 37) may determine the
corresponding
color temperature (and/or other light aspects or qualities) and cause the LED
lamp 10 or
LED lighting device 20 to operate at the corresponding color temperature
(and/or other light
aspects or qualities). For example, if the switch control unit 35 determines
that the switch
selector 34 is in switch position 32a, the switch control unit 35 may then
determine that the
corresponding color temperature is 3000K and cause the LED lamp 10 or LED
lighting
device 20 to be operated at 3000K. For example, if the switch control unit 34
determines
that the switch selector 34 is in the switch position 32a, the switch control
unit 35 may cause
the provider circuit 17 corresponding to the switch position 32a to provide a
controlled
current to at least one of the two or more LED packages 18.
If the switch control unit 35 determines that the status of the switch 30
places the
LED lamp 10 or LED lighting device 20 in the configurable operating mode, the
switch
control unit 35 may cause the LED lamp 10 or LED lighting device 20 to be
operated at
light aspects or qualities indicated by the last received signal from the
remote switch 40. For
example, the memory element 36 may store an indication of the last received
signal from
23
CA 3021693 2018-10-22
the remote switch 40, a current/most recently used operating color
temperature, brightness,
and/or CRI indicator, and/or the like such that the LED lamp 10 or the
lighting device 20
may be operated at the most recently user-selected light aspects or qualities.
In another
example, if the switch control unit 35 determines that the status of the
switch 30 places the
LED lamp 10 or LED lighting device 20 in a programmable custom operating mode,
the
switch control unit 35 may operate the LED lamp 10 or LED lighting device 20
accordingly
(e.g., based on a stored custom operating program stored in memory element 36,
and/or the
like).
In example embodiments, if the status of the switch 30 corresponds to a set
operating
mode (e.g., a set operating color temperature, brightness, CRI, and/or the
like), the switch
controller unit 35 may be bypassed. For example, if the switch selector 34 is
in switch
position corresponding to a set operating color temperature and/or the like
(e.g., 32a, 32b,
or 32c), the position of the switch selector 34 may cause the appropriate
provider circuit 17
to be activated when the LED lamp 10 or lighting device 20 is turned on. For
example, the
switch position(s) corresponding to a set operating light aspects or qualities
may be in direct
electrical communication with the corresponding provider circuit 17 such that
placement of
the switch selector 34 into that switch position causes the corresponding
provider circuit 17
to be completed or activated (e.g., when the LED lamp 10 or lighting device 20
is turned
on). Thus, in some example embodiments, the switch control unit 35 may not be
powered
and/or engaged in the operation of the LED lamp 10 or lighting device 20
unless the status
of the switch 30 corresponds to a configurable and/or custom programmable
mode. In some
embodiments, a set operating mode may set one or more light aspects or
qualities, while
allowing one or more other light aspects or qualities to be configured. For
example, a set
operating mode may set the operating color temperature and CRI of the LED lamp
10 or
lighting device 20 but allow the brightness to be modified. In another
example, a set
operating mode may set the operating color and brightness of the LED lamp 10
or lighting
device 20 but allow the CRI to be modified. For example, in some example
embodiments,
if the status of the switch 30 corresponds to a set operating color
temperature mode, the
switch control unit 35 may only be used to receive and process signals from
the remote
switch 40 and cause corresponding actions related to turning the LED lamp 10
or lighting
device 20 on or off, dimming the LED lamp 10 or lighting device 20, modifying
the CRI of
the LED lamp 10 or lighting device 20, and/or the like. For example, if the
switch control
unit 35 receives a signal attempting to change the operating color of the LED
lamp 10 or
lighting device 20 while the LED lamp 10 or lighting device 20 is in a set
operating color
24
CA 3021693 2018-10-22
temperature mode, the switch control unit 35 need not determine if the LED
lamp 10 or
lighting device 20 is in a set operating color temperature mode or the
configurable operating
color temperature mode as the switch control unit 35 cannot affect the circuit
connection
caused by the position of the switch selector 34.
In various embodiments, the switch control unit 35 is in communication with
one or
more sensors 39. For example, the switch control unit 35 may communicate with
one or
more sensors via the communications interface element 38. In an example
embodiment, the
switch control unit 35 communicates with the one or more sensors wirelessly.
In an example
embodiment, the switch control unit 35 is in wired communication with the one
or more
sensors. In an example embodiment, the LED lamp 10 or LED lighting device 20
comprises
the one or more sensors 39. In various embodiments, the one or more sensors 39
may
comprise light sensors, photocells, motion sensors, and/or the like. In an
example
embodiment, the processing element 37 is configured to receive signals from
one or more
sensors 39 (e.g., via the communications interface element 38) and causes the
operation of
the LED lamp 10 or LED lighting device 20 to be adjusted, modified, or the
like based on
the received signals. In an example embodiment, the processing element 37 only
adjusts,
modifies, or the like the operation of the LED lamp 10 or LED lighting device
20 based on
signals received from one or more sensors 39 when the status of the switch 30
corresponds
to a configurable operating mode. In an example embodiment, the processing
element 37
adjusts, modifies, or the like the operation of the LED lamp 10 or LED
lighting device 20
based signals received from the one or more sensors 39 when the status of the
switch 30
corresponds to a set operating mode such that the light in the room or space
where the LED
lamp 10 or LED lighting device 20 is located is in accordance with the user
selected set
operating mode.
In an example embodiment, the sensor is a light sensor or photo sensor and the
adjusting, modifying, or the like of the operation of the LED lamp 10 or LED
lighting device
20 comprises dimming or brightening the light emitted by the LED lamp 10 or
LED lighting
device 20 such that the brightness in the room or space where the LED lamp 10
or LED
lighting device 20 is located (e.g., due to natural light, light emitted by
the LED lamp 10 or
LED lighting device 20, and/or other light sources) is in accordance with a
predefined
threshold or goal brightness level. In an example embodiment, the sensor is a
light sensor
or photo sensor and the adjusting, modifying, or the like of the operation of
the LED lamp
or LED lighting device 20 comprises changing the color temperature or CRI of
the light
emitted by the LED lamp 10 or LED lighting device 20 such that the brightness
in the room
CA 3021693 2018-10-22
or space where the LED lamp 10 or TED lightim,, device 20 is located (e.g.,
due to natural
light, light emitted by the LED lamp 10 or LED lighting device 20, and/or
other light
sources) is in accordance with a predefined goal color temperature or CRI. In
an example
embodiment, the adjusting, modifying, or the like of the operation of the LED
lamp 10 or
LED lighting device 20 comprises dimming or brightening the light emitted by
the LED
lamp 10 or LED lighting device 20 in response to a motion sensor detecting the
presence of
a person in the room or space or having not detected the presence of anyone in
the room or
space for a predetermined threshold amount of time.
Example Remote Switch
Example embodiments of the present invention comprise a remote switch 40. In
example embodiments, a remote switch 40 may be a wall mounted switch mounted
in the
same room as the LED lamp 10 or LED lighting device 20 and/or within a short
range
communication technology range of the LED lamp 10 or LED lighting device 20.
For
example, the remote switch 40 may be a wall and/or junction box mounted toggle
switch,
dimmer switch and/or the like in wired communication with the switch control
unit 35. In
another example, the remote switch 40 may be a handheld device (e.g., a remote
control, or
computing entity 40') that is within the same room as the LED lamp 10 or LED
lighting
device 20, within a short range communication technology range of the LED lamp
10 or
LED lighting device 20, in communication with the switch control unit 35
through a wireless
network, and/or the like. In example embodiments, the remote switch 40 may be
in wired
or wireless communication with the switch control unit 35. For example, the
remote switch
40 may be configured to control the operation of the LED lamp 10 or lighting
device 20 or
aspects thereof by providing a signal to the switch control unit 35 indicating
user selection,
interaction, and/or the like with one or more interactive elements of the
remote switch 40.
For example, the remote switch 40 may be configured to allow a user to toggle
through two
or more operating color temperatures, brightness, CRIs, and/or other light
aspects or
qualities of the LED lamp 10 or LED lighting device 20. In example
embodiments, the
toggling of the remote switch 40 to change or modify the operating light
aspects or qualities
could be at any time interval from lms to I min,
For example, the remote switch 40 may be configured to cause the LED lamp 10
or
lighting device 20 to turn on or off, control the brightness of the LED lamp
10 or lighting
device 20 (e.g., through a dimmer switch), change the operating light aspects
or qualities of
the LED lamp 10 or lighting device 20, program a programmable custom operating
mode,
26
CA 3021693 2018-10-22
and/or the like. An example remote switch 40 is iflustrated in Figure 5. In
example
embodiments, the remote switch 40 comprises one or more interactive elements
(e.g., 42,
44). For example, the remote switch 40 may comprise an on/off and/or dimmer
switch 42
configured to turn the LED lamp 10 (e.g., the lighting device that the LED
lamp 10 is
secured within) or LED lighting device 20 on or off and/or control the
brightness of the LED
lamp 10 or the LED lighting device 20. The remote switch 40 may comprise a
remote
selector 44 (e.g., a color temperature control) configured for remotely
selecting an operating
color temperature of the LED lamp 10 or lighting device 20 when the LED lamp
10 or LED
lighting device 20 is in the configurable operating mode wherein the operating
color
temperature may be toggled between color temperature A, color temperature B,
and color
temperature C. For example, a user may select the remote selector 44 to cause
the operating
color temperature of the LED lamp 10 or lighting device 20 to change from
color
temperature A to color temperature B, from color temperature B to color
temperature C, or
from color temperature C to color temperature A. In another example, the
remote selector
44 may comprise a button and/or the like for each of the first, second, and
third color
temperatures and the user may select, press, interact with, and/or the like
the button
corresponding to the desired color temperatures. In another example, the
remote selector 44
may comprise a switch or dial having a switch or dial position corresponding
to each of
selectable color temperatures. In example embodiments, the remote selector 44
may be a
slide, push button, rotary, passive infrared and/or other type of interactive
element that the
user may interact with, select, press, touch, voice activate, and/or the like.
Thus, the remote
selector 44 may be configured to allow a user to select a desired operating
color temperature,
brightness, CRI, and/or other operating light aspects or qualities, and/or a
combination
thereof during operation of the LED lamp 10 or LED lighting device 20 (e.g.,
when the LED
lamp 10 or LED lighting device 20 is in the configurable operating mode). In
example
embodiments, the remote switch 40 may comprise additional user interface
components as
appropriate for the application.
The remote switch 40 may further comprise a communication interface 48. In
example embodiments, the communication interface 48 may be a part of a control
unit that
is similar to the switch control unit 35 (e.g., the control unit may comprise
a processing
element and/or memory element in addition to the communication interface 48).
In example
embodiments, the communication interface 48 is configured to provide a signal
to the
communication interface element 38 indicating user selection and/or
interaction with the
on/off and/or dimmer switch 42, the remote selector 44, and/or the like.
27
CA 3021693 2018-10-22
For example, the communications interface 48 may be configured to communicate
with the switch control unit 35. For example, the communications interface 48
may be
configured to provide a signal to the communications interface element 38
indicating user
selection of, activation of, and/or interaction with an on/off and/or dimmer
switch 42, remote
selector 44, and/or the like. Such communication may be executed using a wired
data
transmission protocol, such as fiber distributed data interface (FDDI),
digital subscriber line
(DSL), Ethernet, asynchronous transfer mode (ATM), frame relay, data over
cable service
interface specification (DOCSIS), or any other wired transmission protocol.
Similarly, the
communications interface 48 may be configured to communicate via a wireless
communication technology, such as a short range communication technology. For
example,
the communications interface 48 may be configured to receive and/or send
signals using
IEEE 802.11 (Wi-Fi), Wi-Fi Direct, 802.16 (WiMAX), ultra wideband (UWB),
infrared
(IR) protocols, near field communication (NFC) protocols, Wibree, Bluetooth
protocols,
wireless universal serial bus (USB) protocols, and/or any other wireless
protocol.

entity 40'
that can be used in conjunction with embodiments of the present invention. In
particular, the
computing entity 40' may be configured to operate and/or execute an
application configured
to cause the computing entity 40' to act as a remote switch 40. For example,
the computing
entity 40' may operate and/or execute an application configured to communicate
with the
switch control unit 35 and/or cause one or more aspects (e.g., brightness,
CR1, color
temperature, and/or the like and/or a combination thereof) of light emitted by
the LED lamp
or LED lighting device 20 to be modified. In example embodiments, the
computing entity
40' may be a mobile computing entity such as a mobile phone, tablet, phablet,
wearable
computing device, personal digital assistant (PDA), MP3 player, and/or the

406,
respectively. The signals provided to and received from the transmitter 404
and the receiver
406, respectively, may include signaling information/data in accordance with
an air

as switch control unit 35, another computing entity 40', and/or the like. In
this regard, the
computing entity 40' may be capable of operating with one or more air
interface standards,
communication protocols, modulation types, and access types. More
particularly, the
computing entity 40' may operate in accordance with any of a number of
wireless
communication standards and protocols. In a particular embodiment, the
computing device
40' may operate in accordance with multiple wireless communication standards
and
protocols, such as GPRS, UMTS, CDMA2000, I xRTT, WCDMA, TD-SCDMA, LIE, E-
UTRAN, EVDO, HSPA, HSDPA, Wi-Fi, WiMAX, UWB, IR protocols, Bluetooth
protocols, USB protocols, and/or any other wireless protocol.
Via these communication standards and protocols, the computing entity 40' can
communicate with various other entities using concepts such as Unstructured
Supplementary Service information/data (USSD), Short Message Service (SMS),
Multimedia Messaging Service (MMS), Dual-Tone Multi-Frequency Signaling
(DTMF),
and/or Subscriber Identity Module Dialer (SIM dialer). The computing entity
40' can also
download changes, add-ons, and updates, for instance, to its firmware,
software (e.g.,
including executable instructions, applications, program modules), and
operating system.
According to one embodiment, the computing entity 40' may include location
determining aspects, devices, modules, functionalities, and/or similar words
used herein
interchangeably. For example, the computing entity 40' may include outdoor
positioning
aspects, such as a location module adapted to acquire, for example, latitude,

sometimes
known as ephemeris data, by identifying the number of satellites in view and
the relative
positions of those satellites. The satellites may be a variety of different
satellites, including
LEO satellite systems, DOD satellite systems, the European Union Galileo
positioning
systems, the Chinese Compass navigation systems, Indian Regional Navigational
satellite
systems, and/or the like. Alternatively, the location information/data may be
determined by
triangulating the computing entity's 40' position in connection with a variety
of other
systems, including cellular towers, access
points, and/or the like. Similarly, the
computing entity 40' may include indoor positioning aspects, such as a
location module
adapted to acquire, for example, latitude, longitude, altitude, geocode,

(e.g., smartphones, laptops) and/or the like. For instance, such technologies
may include
iBeacons, Gimbal proximity beacons, BLE transmitters, Near Field Communication
(NFC)
transmitters, and/or the like. These indoor positioning aspects can be used in
a variety of
settings to determine the location of someone or something to within inches or
centimeters.
The computing entity 40' may also comprise a user interface (that can include
a
display 416 coupled to a processing element 408) and/or a user input interface
(coupled to
a processing element 408). For example, the user interface may be an

and/or cause
display of information. The user input interface can comprise any of a number
of devices
allowing the computing entity 40' to receive data, such as a keypad 418 (hard
or soft), a

conventional numeric (0-9) and related keys (#, *), and other keys used for
operating the
computing entity 40' and may include a full set of alphabetic keys or set of

providing input, the
user input interface can be used, for example, to activate or deactivate
certain functions,
such as screen savers and/or sleep modes. Through such inputs the computing
entity 40' can
collect contextual information/data as part of the telematics data.
The computing entity 40' can also include volatile storage or memory 422
and/or

the computing entity 40'.
Example Method of Operating an LED Lamp or LED Lighting Device
CA 3021693 2018-10-22
Figure 7 provides a flowchart illustrating processes and procedures for an
example
method for operating an LED lamp 10 or LED lighting device 20. Starting at
block 102, a
user uses the switch 30 to select the preferred operation mode for the LED
lamp 10 or LED
lighting device 20. For example, the user may place the switch selector 34 in
the desired
switch position 32 (e.g., 32a, 32b, 32c, 32d). For example, the switch 30 may
be used to
select one of the set operating modes or the configurable operating mode. In
an example
embodiment, the switch 30 may be used to select a programmable custom
operating mode.
At block 104, the LED lamp 10 or LED lighting device 20 may be installed. For
example, the LED lamp 10 may be secured within a socket of a lighting device.
In another
example, the LED lighting device 20 may be put into electrical connection with
line voltage
by plugging a two- or three-prong polarized plug into a wall receptacle and
the LED lighting
device 20 may be placed in a desired position. In another example, the LED
lighting device
20 may be electrically connected to line voltage by connecting wires of the
LED lighting
device 20 to line voltage wires of a junction box and mounting the LED
lighting device 20
to a ceiling, wall, and/or the like.
At some time after the LED lamp 10 or LED lighting device 20 is installed, the
LED
lamp 10 or lighting device 20 is turned on, at block 112. For example, a user
may turn on
the LED lamp 10 or LED lighting device 20 by interacting with, selecting,
pressing, and/or
the like an on/off or power button, switch, and/or the like. For example, the
user may interact
with, select, press, and/or the like the on/off and/or dimmer switch 42 on the
remote switch
40, the remote switch 40 may provide an on/off signal to the switch control
unit 35, and the
switch control unit 35 may cause the LED lamp 10 or LED lighting device 20 to
turn on.
At block 114, it may be determined if the LED lamp 10 or LED lighting device
20
is in a set operating mode. For example it may be determined if the switch 30
was set in a
position indicating that the LED lamp 10 or LED lighting device 20 is to be
operated in a
set operating mode (e.g., with set light aspects or qualities). For example,
the switch
controller unit 35 (e.g., the processing element 37) may determine if the LED
lamp 10 or
LED lighting device 20 is in a set operating mode. In some embodiments,
determining if the
LED lamp 10 or LED lighting device 20 is in a set operating mode does not
require an active
determination. For example, the switch 30 may be wired such that if the switch
selector 34
is in set operating mode switch position, the switch control unit 35 may be
bypassed and the
provider circuit 17 corresponding to the selected set operating light aspects
or qualities may
be activated, completed, and/or the like causing the LED lamp 10 or LED
lighting device
20 to be operated at the set operating light aspects or qualities.
31
CA 3021693 2018-10-22
If, at block 114, it is determined that the LCD lamp 10 or LED lighting device
20 is
in a set operating mode, the LED lamp 10 or LED lighting device 20 is operated
at the set
operating light aspects or qualities (e.g., color temperature, brightness,
CRI, and/or the like),
at block 116. For example, the driver circuitry 19 may operate at least one of
the two or
more LED packages 18 to cause the LED lamp 10 or LED lighting device 20 to
emit light
at the set operating color temperature.
If, at block 114, it is determined that the LED lamp 10 or LED lighting device
20 is
not in a set operating mode, the process continues to block 118. At block 118,
the color
temperature that the LED lamp 10 or LED lighting device 20 was last operated
at is
identified. For example, the switch control unit 35 (e.g., the processing
element 37, memory
element 36, and/or the like) may identify the color temperature, brightness,
CRI, and/or the
like that the LED lamp 10 or LED lighting device 20 was last operated at. For
example, the
memory element 36 may store the most recent operating color temperature,
brightness, CRI,
and/or the like (and/or an indicator thereof), which may be used to identify
the light aspects
or qualities that the LED lamp 10 or LED lighting device 20 was last operated
at. For
example, the identified color temperature is applied or implemented as the
operating color
temperature.
At block 120, the LED lamp 10 or LED lighting device 20 is operated to provide
light having the determined or identified light aspects or qualities. For
example, the switch
control unit 35 may cause the driver circuitry 19 to operate the LED lamp 10
or LED lighting
device 20 at the operating light aspects or qualities (e.g., color
temperature, brightness, CRI,
and/or the like, and/or a combination thereof). For example, the driver
circuitry 19 may
operate at least one of the two or more LED packages 18 to cause the LED lamp
10 or LED
lighting device 20 to emit light at the operating light aspects or qualities.
For example, the
driver circuitry 19 may operate a specific set of LED packages 18 to cause the
LED lamp
or LED lighting device 20 to emit light at the operating color temperature
(and/or
brightness and/or CRI). In another example, the driver circuitry 19 may drive
one or more
LED packages 18 such that the LED lamp 10 or LED lighting device 20 emits
light at the
operating color temperature (and/or brightness and/or CRI). In yet another
example, the
switch control unit 35 may adjust one or more optical elements to cause the
LED lamp 10
or LED lighting device 20 to emit light at the operating color temperature
(and/or brightness
and/or CRI).
At block 122, it is determined if a light aspect or quality change signal is
received.
For example, the switch control unit 35 may determine if a light aspect or
quality change
32
CA 3021693 2018-10-22
signal is received from the remote switch 40. For example, the signal may
indicate user
selection of the color selector 44, indicating the user would like to change
the operating
color temperature of the LED lamp 10 or the LED lighting device 20. For
example, it is
determined if a light aspect or quality change signal is received by the
communication
interface element 38. If, at block 122, it is determined that a light aspect
or quality change
signal is not received, the process returns to block 120.
If, at block 122, it is determined that a light aspect or quality change
signal has been
received, one or more operating light aspects or qualities of the LED lamp 10
or LED
lighting device 20 are modified accordingly. For example, the switch control
unit 35 may
activate a provider circuit 17 corresponding to the modified operating color
temperature
(and/or brightness and/or CRI, and/or the like) and may de-activate the
previously activated
provider circuit 17 corresponding to the previous operating color temperature
(and/or
brightness and/or CRI, and/or the like). For example, the switch control unit
35 may cause
one provider circuit 17 to provide a controlled electric current to the
corresponding at least
one LED package 18 such that the LED lamp 10 or LED lighting device 20 emits
light
having the modified operating light aspects or qualities and cause another
provider circuit
17 to stop providing an electric current to the corresponding at least one LED
package 18
corresponding to the previous operating light aspect or qualities. For
example, the memory
element 36 may be updated to indicate the new most recent operating light
aspects or
qualities. In example embodiments, the switch control unit 35 and/or driver
circuitry 19 are
configured to start operating the at least one of the two or more LED packages
18 at the
modified operating light aspects or qualities within two seconds or less of
the receipt of the
signal indicating user-selection of the modified operating light aspects or
qualities. After the
one or more operating light aspects or qualities are modified, the process
returns to block
120.
Alternative Example Method of Operating an LED Lamp or LED Lighting Device
Figure 8 provides a flowchart illustrating processes and procedures for an
alternative
method for operating an LED lamp 10 or LED lighting device 20. Starting at
block 202, a
user uses the switch 30 to select the preferred operation mode for the LED
lamp 10 or LED
lighting device 20. For example, the user may place the switch selector 34 in
the desired
switch position 32 (e.g., 32a, 32b, 32c, 32d). For example, the switch 30 may
be used to
select one of the set operating modes or the configurable operating mode. In
an example
embodiment, the switch 30 may be used to select a programmable custom
operating mode.

CA 3021693 2018-10-22
At block 204, the LED lamp 10 or LED lighting device 20 may be installed. For
example, the LED lamp 10 may be secured within a socket of a lighting device.
In another
example, the LED lighting device 20 may be put into electrical connection with
line voltage
by plugging a two- or three-prong polarized plug into a wall receptacle and
the LED lighting
device 20 may be placed in a desired position. In another example, the LED
lighting device
20 may be electrically connected to line voltage by connecting wires of the
LED lighting
device 20 to line voltage wires of a junction box and mounting the LED
lighting device 20
to a ceiling, wall, and/or the like. In yet another example, a wiring harness
terminating in a
standard size lamp base connector may be secured into the socket of a recessed
lighting
fixture. The LED lighting device 20 may then be placed, mounted, installed,
and/or the like
in a desired position.
At some time after the LED lamp 10 or LED lighting device 20 is installed, the
LED
lamp 10 or lighting device 20 is turned on, at block 212. For example, a user
may turn on
the LED lamp 10 or lighting device 20 by interacting with, selecting,
pressing, and/or the
like an on/off or power button, switch, and/or the like. For example, the user
may interact
with, select, press, and/or the like the on/off and/or dimmer switch 42 on the
remote switch
40, the remote switch 40 may provide an on/off signal to the switch control
unit 35, and the
switch control unit 35 may cause the LED lamp 10 or LED lighting device 20 to
turn on.
At block 214, the color temperature that the LED lamp 10 or LED lighting
device
20 was last operated at is identified. For example, the switch control unit 35
(e.g., the
processing element 37, memory element 36, and/or the like) may identify the
color
temperature that the LED lamp 10 or LED lighting device 20 was last operated
at. For
example, the memory element 36 may store the most recent operating light
aspects or
qualities, which may be used to identify the color temperature, brightness,
CRI, and/or the
like that the LED lamp 10 or LED lighting device 20 was last operated at. For
example, the
identified light aspects or qualities are applied or implemented as the
operating light aspects
or qualities.
At block 216, the LED lamp 10 or LED lighting device 20 is operated at the
operating light aspects or qualities. For example, the switch control unit 35
may cause the
driver circuitry 19 to operate the LED lamp 10 or LED lighting device 20 at
the operating
light aspects or qualities (e.g., color temperature, brightness, CRI, and/or
the like). For
example, the driver circuitry 19 may operate at least one of the two or more
LED packages
18 to cause the LED lamp 10 or LED lighting device 20 to emit light at the
operating color
temperature. For example, the driver circuitry 19 may operate a specific set
of LED
34
CA 3021693 2018-10-22
packages 18 to cause the LED lamp 10 or LED lighting device 20 to emit light
at the
operating color temperature (and/or brightness and/or CRI). In another
example, the driver
circuitry 19 may drive one or more LED packages 18 such that the LED lamp 10
or LED
lighting device 20 emits light at the operating color temperature (and/or
brightness and/or
CRI). In yet another example, the switch control unit 35 may adjust one or
more optical
elements to cause the LED lamp 10 or LED lighting device 20 to emit light at
the operating
color temperature (and/or brightness and/or CRI and/or the like).
At block 218, it is determined if a light aspect or quality change signal is
received.
For example, the switch control unit 35 may determine if a light aspect or
quality change
signal is received from the remote switch 40. For example, the signal may
indicate user
selection of the color selector 44, indicating the user would like to change
one or more
operating light aspects or qualities of the LED lamp 10 or the LED lighting
device 20. In
another example, the signal may indicate user selection of the dimmer switch
42, indicating
the user would like to change the brightness of the light emitted by the LED
lamp 10 or the
LED lighting device 20. For example, it is determined if a light aspect or
quality change
signal is received by the communication interface element 38. If, at block
218, it is
determined that a light aspect or quality change signal is not received, the
process returns to
block 216.
If, at block 218, it is determined that a light aspect or quality change
signal has been
received, it determined if the LED lamp 10 or LED lighting device 20 is in a
set operating
mode, at block 220. For example it may be determined if the switch 30 was set
in a position
indicating that the LED lamp 10 or LED lighting device 20 is to be operated in
a set
operating mode. For example, the switch control unit 35 (e.g., processing
elements 37) may
determine if the LED lamp 10 or LED lighting device 20 is to be operated in a
set operating
mode. In some embodiments, determining if the LED lamp 10 or LED lighting
device 20 is
in a set operating mode does not require an active determination. For example,
the switch
30 may be wired such that if the switch selector 34 is in set operating mode
switch position,
the switch control unit 35 may be bypassed and the provider circuit 17
corresponding to the
selected set operating mode (e.g., a set operating color temperature) may be
activated,
completed, and/or the like causing the LED lamp 10 or LED lighting device 20
to be
operated at the set operating light aspects or qualities.
If, at block 220, it is determined that the LED lamp 10 or LED lighting device
20 is
in a set operating mode, the process returns to block 216 without modifying
the operating
CA 3021693 2018-10-22
light aspects or qualities. If, at block 220, it is determined that the LED
lamp 10 or LED
lighting device 20 is not in a set operating mode, the process continues to
block 222.
At block 222, the operating light aspects or qualities of the LED lamp 10 or
LED
lighting device 20 are modified in accordance with the received light aspect
or quality
change signal. For example, the switch control unit 35 may activate a provider
circuit 17
corresponding to a modified operating color temperature and may de-activate
the previously
activated provider circuit 17 corresponding to the previous operating color
temperature. For
example, the switch control unit 35 may cause one provider circuit 17 to
provide a controlled
electric current to the corresponding at least one LED package 18 such that
the LED lamp
or LED lighting device 20 emits light at the modified operating color
temperature (and
possibly at a modified brightness and/or CRI) and cause another provider
circuit 17 to stop
providing an electric current to the corresponding at least one LED package
18. For
example, the memory element 36 may be updated to indicate the new most recent
operating
light aspects or qualities. In example embodiments, the switch control unit 35
and/or driver
circuitry 19 are configured to start operating the at least one of the two or
more LED
packages 18 at the modified operating light aspects or qualities within two
seconds or less
of the receipt of the signal indicating user-selection of the second operating
light aspects or
qualities. After the operating light aspects or qualities are modified, the
process returns to
block 216.
In example embodiments, an LED lamp 10 or LED lighting device 20 may be
configured to provide a programmable custom operating mode. For example, a
user may
select a custom operating color temperature (and/or brightness and/or CRI
and/or the like)
and/or program the LED lamp 10 or LED lighting device 20 (e.g., the switch
control unit 35
thereof) to operate the LED lamp 10 or LED light device 20 in accordance with
a custom
programmed temporal operating program. For example, with reference to Figure
8, at block
202, the switch 30 of the LED lamp 10 or the LED lighting device 20 may be
placed in a
position corresponding to a programmable custom operating mode. The user may
further
program the programmable custom operating mode (e.g., using the switch 30,
additional
user interface components, remote switch 40, and/or the like). In an example
embodiment,
programming programmable custom operating mode may comprise providing input
identifying a custom operating color, selecting a brightness, selecting a CRI,
and/or the like.
For example, the LED lamp 10 or LED lighting device 20 may comprise first LED
packages
18a and second LED packages 18b, wherein the first LED packages 18a are
configured to
emit light of a different color temperature than the second LED packages 18b.
The switch
36
CA 3021693 2018-10-22
control unit 35 may be configured to determine a ratio of the number of first
LED packages
18a to the number of second LED packages 18b that should be activated to
provide the
custom operating color temperature. For example, the first LED packages 18a
may be
configured to emit light at 3000K and the second LED packages 18b may be
configured to
emit light at 5000k. The programmable custom operating color temperature may
be
programmed to be 4500K. In this example, the switch control unit 35 may be
configured to
determine that one-fourth of the first LED packages 18a and three-fourths of
the second
LED packages 18b should be activated to provide a light at a color temperature
of 4500K.
The switch control unit 35 may then be configured to activate one or more
provider circuits
17 in order to activate the appropriate LED packages 18 when the LED lamp 10
or LED
lighting device 20 is turned on to provide light of the programmed custom
operating color
temperature. In another example, the switch control unit 35 may determine how
one or more
LED packages 18 should be driven to provide light having the user-selected
light aspects or
qualities. In another example, the switch control unit 35 may cause the
primary or secondary
optics, the amount of phosphor conditioning light from one or more LED
packages 18,
and/or the like to be modified such that the LED lamp 10 or LED lighting
device 20 emits
light having the user-selected light aspects or qualities. At block 204, the
LED lamp 10 or
LED lighting device 20 may be installed.
At some time after the LED lamp 10 or LED lighting device 20 is installed, the
LED
lamp 10 or lighting device 20 is turned on, at block 212. For example, a user
may turn on
the LED lamp 10 or lighting device 20 by interacting with, selecting,
pressing, and/or the
like an on/off or power button, switch, and/or the like. For example, the user
may interact
with, select, press, and/or the like the on/off and/or dimmer switch 42 on the
remote switch
40, the remote switch 40 may provide an on/off signal to the switch control
unit 35, and the
switch control unit 35 may cause the LED lamp 10 or LED lighting device 20 to
turn on.
At block 214, the light aspects or qualities (e.g., color temperature,
brightness, CR1,
and/or the like) that the LED lamp 10 or LED lighting device 20 are to be
operated at may
be identified. For example, the color temperature the LED lamp 10 or LED
lighting device
20 was last operated at may be identified. In another example, the memory
element 36 may
be accessed (e.g., by the processing element 37) to identify the appropriate
operating light
aspects or qualities based on the programmed custom operating mode, the time
of day,
and/or the like. If the LED lamp 10 or LED lighting device 20 is in a
programmable custom
operating mode in which a custom operating color temperature has been
programmed, the
switch control unit 35 may determine the appropriate combination of LED
packages 18 to
37
CA 3021693 2018-10-22
be activated to provide light of the custom operating color temperature and
the
corresponding provider circuits 17 that are to be activated, the current at
which the provider
corresponding provider circuits 17 are to be activated with, and/or the like.
At block 216, the LED lamp 10 or LED lighting device 20 is operated at the
identified operating light aspects or qualities. For example, the switch
control unit 35 may
cause the driver circuitry 19 to operate the LED lamp 10 or LED lighting
device 20 at the
operating light aspects or qualities. For example, the driver circuitry 19 may
operate at least
one of the two or more LED packages 18 to cause the LED lamp 10 or LED
lighting device
20 to emit light at the identified operating color temperature. For example,
the appropriate
provider circuits for providing the identified operating color temperature are
activated such
that the LED lamp 10 or LED lighting device 20 provides light of the user-
selected operating
color temperature. For example, the driver circuitry 19 may drive one or more
LED
packages 18 to provide light having the identified light aspects or qualities.
At block 218, it is determined if a light aspect or quality change signal is
received.
If a light aspect or quality change signal has not been received (e.g., as
determined by the
switch control unit 35), the process returns to block 216. If a light aspect
or quality change
signal is received, the process continues to step 220, wherein it is
determined if the LED
lamp 10 or LED lighting device 20 is in a set operating mode. In some
embodiments, the
programmable custom operating mode may be a set mode, wherein the operating
color
temperature (and/or other light aspects or qualities) of the LED lamp 10 or
LED lighting
device 20 cannot be modified during operation of the LED lamp 10 or LED
lighting device
20. In some example embodiments, the programmable custom operating mode may be
a
selectively configurable mode, wherein the operating color temperature (or
other light
aspect or quality) of the LED lamp 10 or LED lighting device 20 may be
modified during
operation of the LED lamp 10 or LED lighting device 20. For example, the
operating color
temperature of the LED lamp 10 or LED lighting device 20 may be switched
between one
or more predefined color temperatures (e.g., the first, second, and third
color temperatures)
and the programmed custom operating color temperature (and/or brightness
and/or CRI
and/or the like). Thus, the switch control unit 35 may determine (e.g., based
on the status of
the switch 30 and/or one or more programs and/or the like stored by the memory
element
36) if the LED lamp 10 or LED lighting device 20 is in a set mode or a
configurable mode.
If it is determined that the LED lamp 10 or LED lighting device 20 is in a set
mode,
the process returns to block 216, and the LED lamp 10 or LED lighting device
20 continues
to provide light at the operating light aspects or qualities. If it is
determined that the LED
38
CA 3021693 2018-10-22
lamp 10 or LED lighting device 20 is in a configurable mode, the process
continues to block
222. At block 222, the operating light aspects or qualities are modified in
accordance with
the received light aspect or quality change signal. The process then returns
to block 216.
Example Method of Operating an LED Lamp or LED Lighting Device Using a
Sensor
Figure 9 provides a flowchart illustrating processes and procedures for an
alternative
method for operating an LED lamp 10 or LED lighting device 20 based on signals
received
from one or more sensors 39. Starting at block 302, a user uses the switch 30
to select the
preferred operation mode for the LED lamp 10 or LED lighting device 20. For
example, the
user may place the switch selector 34 in the desired switch position 32 (e.g.,
32a1 32b, 32c,
32d). For example, the switch 30 may be used to select one of the set
operating modes or
the configurable operating mode. In an example embodiment, the switch 30 may
be used to
select a programmable custom operating mode. In an example embodiment, the
switch 30
may be used to select a sensor-based or sensor-controlled operating mode.
At block 304, the LED lamp 10 or LED lighting device 20 may be installed. For
example, the LED lamp 10 may be secured within a socket of a lighting device.
In another
example, the LED lighting device 20 may be put into electrical connection with
line voltage
by plugging a two- or three-prong polarized plug into a wall receptacle and
the LED lighting
device 20 may be placed in a desired position. In another example, the LED
lighting device
20 may be electrically connected to line voltage by connecting wires of the
LED lighting
device 20 to line voltage wires of a junction box and mounting the LED
lighting device 20
to a ceiling, wall, and/or the like. In yet another example, a wiring harness
terminating in a
standard size lamp base connector may be secured into the socket of a recessed
lighting
fixture. The LED lighting device 20 may then be placed, mounted, installed,
and/or the like
in a desired position. In various embodiments, the LED lamp 10 or LED lighting
device 20
may comprise one or more sensors 39. In an example embodiment, the LED lamp 10
or
LED lighting device 20 does not comprise one or more sensors 39 and
installation comprises
installing the one or more sensors 39 and placing the one or more sensors 39
in
communication with the switch control unit 35. For example, the one or more
sensors 39
may be paired with the LED lamp 10 or LED lighting device 20 such that the one
or more
sensors 39 and the LED lamp 10 or LED lighting device 20 may communicate via
Bluetooth,
low energy Bluetooth, and/or the like.
39
CA 3021693 2018-10-22
At some time after the LED lamp 10 or LED lighting device 20 is installed, the
LED
lamp 10 or lighting device 20 is turned on, at block 312. For example, a user
may turn on
the LED lamp 10 or lighting device 20 by interacting with, selecting,
pressing, and/or the
like an on/off or power button, switch, and/or the like. For example, the user
may interact
with, select, press, and/or the like the on/off and/or dimmer switch 42 on the
remote switch
40, the remote switch 40 may provide an on/off signal to the switch control
unit 35, and the
switch control unit 35 may cause the LED lamp 10 or LED lighting device 20 to
turn on.
At block 314, the color temperature that the LED lamp 10 or LED lighting
device
20 was last operated at is identified. For example, the switch control unit 35
(e.g., the
processing element 37, memory element 36, and/or the like) may identify the
color
temperature that the LED lamp 10 or LED lighting device 20 was last operated
at. For
example, the memory element 36 may store the most recent operating light
aspects or
qualities, which may be used to identify the color temperature, brightness,
CRI, and/or the
like that the LED lamp 10 or LED lighting device 20 was last operated at. For
example, the
identified light aspects or qualities are applied or implemented as the
operating light aspects
or qualities.
At block 316, the LED lamp 10 or LED lighting device 20 is operated at the
operating light aspects or qualities. For example, the switch control unit 35
may cause the
driver circuitry 19 to operate the LED lamp 10 or LED lighting device 20 at
the operating
light aspects or qualities (e.g., color temperature, brightness, CRI, and/or
the like). For
example, the driver circuitry 19 may operate at least one of the two or more
LED packages
18 to cause the LED lamp 10 or LED lighting device 20 to emit light at the
operating color
temperature. For example, the driver circuitry 19 may operate a specific set
of LED
packages 18 to cause the LED lamp 10 or LED lighting device 20 to emit light
at the
operating color temperature (and/or brightness and/or CRI). In another
example, the driver
circuitry 19 may drive one or more LED packages 18 such that the LED lamp 10
or LED
lighting device 20 emits light at the operating color temperature (and/or
brightness and/or
CRI). In yet another example, the switch control unit 35 may adjust one or
more optical
elements to cause the LED lamp 10 or LED lighting device 20 to emit light at
the operating
color temperature (and/or brightness and/or CRI and/or the like).
At block 318, a sensor signal is received from the one or more sensors 39. For
example, the one or more sensors 39 may provide a sensor signal to the switch
control unit
35 (e.g., via a wired or wireless communication). The switch control unit 35
may receive
the sensor signal (e.g., via the communications interface element 38) and
process the sensor
CA 3021693 2018-10-22
signal (e.g., via the processing element 37). For example, the one or more
sensors 39 may
comprise a motion sensor and the sensor signal may indicate that a person or a
motion has
been detected in the room or space and therefore that the LED lamp 10 or LED
lighting
device 20 should be turned on, brightened, and/or the like, In another
example, the one or
more sensors 39 may comprise a motion sensor and the sensor signal may
indicate that no
people or no motion has been detected in the room or space for a predetermined
threshold
amount of time and therefore that the LED lamp 10 or LED lighting device 20
should be
turned off, dimmed, and/or the like. In another example, the one or more
sensors 39 may
comprise a light level sensor, a photocell, and/or the like configured to
determine and/or
measure the ambient light level and the sensor signal may indicate the
brightness and/or
light level in the room or space. The operation of the LED lamp 10 or LED
lighting device
20 should be modified (e.g., by the driver circuit 19 and/or switch control
unit 35) to
dim/brighten, change the operating color temperature, or change the CRI of the
light within
the room to be in accordance with user preferences and/or set preferences when
taking into
account the ambient light in the room (as determined by the one or more
sensors 39). For
example, the voltage applied to one or more of the LED packages 18 by one or
more
provider circuits 17 may be increased or reduced to adjust the operating light
aspects or
qualities based on a signal received from one or more sensors 39 integrated
into the LED
lamp 10 or LED lighting device 20 and/or in communication therewith (e.g., via
the
communications interface element 38). In another example, the one or more
sensors 39 may
comprise a light sensor or photocell and the sensor signal may indicate the
color temperature
and/or CRI in the room or space.
At block 320, it is determined if the LED lamp 10 or LED lighting device 20 is
in a
set operating mode. For example it may be determined if the switch 30 was set
in a position
indicating that the LED lamp 10 or LED lighting device 20 is to be operated in
a set
operating mode (and/or a non-adjustment mode). For example, the switch control
unit 35
(e.g., processing elements 37) may determine if the LED lamp 10 or LED
lighting device
20 is to be operated in a set operating mode. In some embodiments, determining
if the LED
lamp 10 or LED lighting device 20 is in a set operating mode does not require
an active
determination. For example, the switch 30 may be wired such that if the switch
selector 34
is in set operating mode switch position, the switch control unit 35 may be
bypassed and the
provider circuit 17 corresponding to the selected set operating mode (e.g., a
set operating
color temperature) may be activated, completed, and/or the like causing the
LED lamp 10
or LED lighting device 20 to be operated at the set operating light aspects or
qualities.
41
CA 3021693 2018-10-22
If, at block 320, it is determined that the LED lamp 10 or LED lighting device
20 is
in a set operating mode (and/or non-adjustment mode), the process returns to
block 316
without modifying the operating light aspects or qualities, if, at block 320,
it is determined
that the LED lamp 10 or LED lighting device 20 is not in a set operating mode
(e.g., the
LED lamp 10 or LED lighting device 20 is in a sensor adjustment mode), the
process
continues to block 322. In various embodiments, a sensor adjustment mode may
be a
configurable operating mode or a set operating mode. For example, a
configurable operating
mode or a set operating mode that is a sensor adjustment mode provides for a
user to select
the goal light qualities for the room or space where the LED lamp 10 or LED
lighting device
20 is located. For example, a configurable operating mode or a set operating
mode that is a
non-adjustment mode provides for a user to select the operating light
qualities for the LED
lamp 10 or LED lighting device 20.
At block 322, the processing element 37 determines an adjustment and/or
modification to be made to the operating light aspects or qualities of the LED
lamp 10 or
LED lighting device 20 such that the light in the room or space (e.g., due to
natural light,
light emitted by the LED lamp 10 or LED lighting device 20, and/or other light
sources)
will be in accordance with the user-selected and/or goal light qualities
(e.g., a goal
brightness, goal color temperature, goal CRI, and/or the like). The switch
control unit 35
may then modify the operation of the LED lamp 10 or LED lighting device 20 in
accordance
with the determined adjustment and/or modification such that the light in the
room or space
is in accordance with the user-selected and/or goal light qualities. For
example, the switch
control unit 35 may activate a provider circuit 17 corresponding to a modified
operating
color temperature and may de-activate the previously activated provider
circuit 17
corresponding to the previous operating color temperature. For example, the
switch control
unit 35 may cause one provider circuit 17 to provide a controlled electric
current to the
corresponding at least one LED package 18 such that the LED lamp 10 or LED
lighting
device 20 emits light at the modified operating color temperature (and
possibly at a modified
brightness and/or CRI) and cause another provider circuit 17 to stop providing
an electric
current to the corresponding at least one LED package 18. In example
embodiments, the
switch control unit 35 and/or driver circuitry 19 are configured to start
operating the at least
one of the two or more LED packages 18 at the modified operating light aspects
or qualities
within two seconds or less of the receipt of the sensor signal. After the
operating light aspects
or qualities are modified, the process returns to block 316.

Thus, in an example embodiment, the switch 30 can be set to an operating mode
that
enables the use of a motion or ambient light sensor (e.g., dusk to dawn
ambient light sensor)
that may be physically attached and/or apart of the LED lamp 10 or LED
lighting device 20
with the ability to select host or slave so downstream fixtures can be
controlled thru the
sensors on the host designated fixture. For example, the sensor on a first LED
lamp 10 or
LED lighting device 20 of a plurality of LED lamps 10 or LED lighting devices
20 in a
space (e.g., in a room, neighboring rooms, a user selected/defined space
within a building,
and/or the like) may be set as the host and used to control the operation of
the remaining of
the plurality of LED lamps 10 or LED lighting devices 20 in the space that are
set as the
slaves. In an example embodiment, when the switch 30 is in the position
selecting the
sensor-based or sensor-controlled operating mode, the LED lamp 10 or LED
lighting device
20 may be configured to receive and act on user input received from one or
more remote
switches 40, 40'. For example, a user may control the LED lamp 10 or LED
lighting device
20 using a wall switch, Wi-Fl or other App-based control system that could be
part of a
building control system or other control system that would control the
fixtures
independently.
