DETAILED DESCRIPTION
[0079] It should be understood that the invention is not limited in its
application to
the details of construction and the arrangement of components set forth in the
following
description or illustrated in the drawings. The invention is capable of other
example
embodiments and of being practiced or of being carried out in various ways.
Also, it is to
be understood that the phraseology and terminology used herein is for the
purpose of
description and should not be regarded as limiting. The use of "including,"
"comprising,"
or "having" and variations thereof herein is meant to encompass the items
listed thereafter
and equivalents thereof as well as additional items. Unless limited otherwise,
the terms
"connected," "coupled," and "mounted," and variations thereof herein are used
broadly
and encompass direct and indirect connections, couplings, and mountings. In
addition,
the terms "connected" and "coupled" and variations thereof are not restricted
to physical,
mechanical or other connections or couplings. The terms upper, lower, vertical
and
horizontal are intended for operative context only and are not necessarily
intended to
limit the invention only to those configurations or orientations. Furthermore,
and as
described in subsequent paragraphs, the specific mechanical, electrical and/or
other
configurations illustrated in the drawings are intended to exemplify
embodiments of the
invention. However, other alternative mechanical, electrical and/or other
configurations
are possible which are considered to be within the teachings of the instant
disclosure.
[0080] The terms "line voltage" and "line voltage power" may include, but
not
limited to, the voltage (and power) that a power line delivers to its
destination, or the
point where it is being used, such as from about 120V to about 277V at 60W, or
other
such voltage levels appearing in power distribution systems in building
structures.
[0081] The terms "low voltage", "low voltage power" and "low power" used
herein
may include, but not limited to, the voltage (and power) such as specified in
Class 2 UL
(formerly known as Underwriters Laboratory) that is rated for electrical
appliances such
AXS-SYX2/CDA 15
Date Recue/Date Received 2021-02-23
as lighting units, such as 48V at 60W maximum, or other such voltage and power
levels
specified in residential and commercial building codes.
[0082] The term "configured installation" used herein in the context of a
grid lighting
network or system may include, but not limited to, an installation which is
configured
according to an appropriate building or energy code, including one or more
instances of a
specified length of a lighting (or power delivery) zone and a specified number
of
interchangeable line voltage lighting modules deployable therein, in order to
approach,
but not exceed, a maximum power delivery rating of a designated line voltage
outlet
(such as a circuit breaker) to power the lighting (or power delivery) zone, to
enable any
one of the interchangeable line voltage lighting modules to be moved from one
designated location to another along the specified length of the lighting (or
power
delivery) zone, and still comply with the maximum power delivery rating of the
designated line voltage outlet.
[00831 The terms "grid lighting system", "grid lighting network", "grid
area", "grid
segment", "grid configuration", and other terms using the adjective "grid"
herein may
include, but not limited to, single or multiple configurations of a track,
housing or other
support structure, in any one or more of such configurations as T-, L-, U-,
square-shaped
or other configurations or combinations thereof, such as a number of x and y
lengths
found at one or more hubs, intersecting two or more tracks, housings or other
support
structures. The grid segments may be in the form of standardized or non-
standard grid
segments.
[0084] While the drawings show and the description describes the "grid"
components
generally defining a 2-dimensional configuration, it is to be understood this
is done
merely for convenience in the drawings and description. It is to be understood
by one
possessing the teachings of this specification, drawings, and claims as set
forth herein, as
may be amended during the prosecution, that the "grid" may extend into a third
dimension and incorporate components not limited to a 2-dimensional
configuration.

[0085] The term "LED" used herein may include, but not be limited to,
semiconductor, electroluminescent, organic, polymeric or other material based
light
sources commonly known as generally as light emitting diodes, as well as
polymeric and
other such light sources, equivalents and variants thereof.
[00861 The term "track lighting module" used herein may include, but not
limited to,
an interchangeable lighting device which provides a track or other elongate
supportive
structure for supporting an array of one or more interchangeable lighting
submodules, for
example with one or more arrays of LEDs, i.e. those which are configured to
electrically
couple with the track or other elongate support.
[0087] The term "non-track lighting module may include, but not limited
to, an
interchangeable lighting device which does not provide a track or other
elongate
supportive structure for supporting an array of one or more interchangeable
lighting
submodules, for example with one or more arrays of LEDs.
[0088] Figure 1 shows a prior art version of a grid lighting system A,
baying a
number of "low voltage" line drops B, which are normally provided at a
designated
distance, such as 8 feet, along each span S in a designated grid area. Each of
the line
drops B is coupled to a dedicated "low voltage" supply line C, which is
powered by a
power supply PS, which in turn is coupled to a designated "line voltage"
circuit breaker
CB. In this case, a power supply PS is required for one or several "low
voltage" line
drops B, and power supply PS1 is shown to supply power to two such "low
voltage"
supply lines C. Further, the group of power supplies PS is usually provided in
a remote
utility room location R housing the circuit breakers CB. This can sometimes
require a
considerable length of "low voltage" supply line extending between each power
supply
PS and the at least one corresponding line drop B. For instance, in a grid
lighting system
with 50 such "low voltage" line drops, there would be a corresponding
requirement for
power supplies PSI to PSn, where n = 50 or a subset thereof, with the
consequent
requirement of 50 lengths of low voltage power supply line between the power
supplies
PS and a corresponding "low voltage" line drop. (The thickened arrows between
each
circuit breaker CB and the adjacent power supply PS in figure 1 denotes "line
voltage", in
AXS4YX2/CDA 17
Date Recue/Date Received 2021-02-23
this case between each circuit breaker CB and the con-esponding power supply
PS.)
10089] Figure 2 shows an example embodiment in the form of a grid
lighting system
10, with a single "line voltage" line drop 12a which, in this case, is held in
at least one
stern structure as shown at 13. Thus, while there may be a number of stem
structures 13
supporting the grid lighting system 10, only one is shown to include a line
drop 12, in this
example, and thus to supply all the spans in a designated grid area. The
single "line
voltage" line drop I2a is coupled to a single "line voltage" supply line 14,
which is drawn
in a thickened chain-dotted line to denote "line voltage" (in contrast to the
"low voltage"
supply line C (shown as chain-double-dotted) in figure 1). The line voltage
supply line
14 is in turn directly coupled to a single designated circuit breaker 16. As
will be
described, the line voltage supply line 14 is able to service an entire
designated grid area,
as will be described. Other example embodiments may involve multiple such grid
areas
in a corresponding multiple of configured installations for a correspondingly
larger target
space to be illuminated, with each supplied by a single line voltage line
drop.
Nonetheless, example embodiments as disclosed may provide a substantial
increase in
efficiency and a reduction in assembly costs, at scale.
10090] Referring to figures 2, 3 and 4, the grid lighting system 10
comprises at least
one elongate support structure, which may be in the form of a housing segment,
in this
example embodiment showing six such housing segments 18, each with a lighting
zone
20. In this case, line drops 12b and 12c do not include or provide a line
voltage supply
line 14.
[0091] Also provided is at least one lighting module 22, which may be
selected from
at least one track lighting module 24 and/or at least one non-track lighting
module, shown
schematically at 26. Referring to figures 2, 3 and 4, the lighting zone 20 of
each housing
segment 18 is configured to extend along a first length dimension Li of the
corresponding housing segment 18, and includes at least one first passage 28
(figure 4)
extending at least part way along the lighting zone 20, to receive the at
least one lighting
module 22 therein. Each housing segment 18 includes a first power supply
segment 30,
AXS-SYXVCDA 18
Date Recue/Date Received 2021-02-23
which is in communication with line voltage supply line 14, to deliver line
voltage power
to the at least one lighting module 22 in the lighting zone 20. In this case,
the first power
supply segment 30 includes a first power supply cable harness, a portion of
which is
shown schematically at 31 (as will be further described below) extending along
the
housing 18. In other example embodiments, the elongate support structure may
be
provided as a rigid, or flexible support structure, such as a frame structure,
without
necessarily having a housing segment, and which may receive a lighting module
thereon.
10092] Referring to figure 3, each track lighting module 24 may include a
lighting
subzone 32 extending along a second length dimension L2 thereof. In this case,
the
second length dimension L2 is aligned with the first length dimension Ll. In
other
example embodiments, the second length dimension L2 may be positioned relative
to the
first length dimension Li at a non-aligned angle such as, for example, an
included angle
of less than 90 degrees, or less than 180 degrees.
[0093] The lighting subzone 32 may include a second passage 34 extending
at least
part way along the lighting subzone 32 to receive at least one lighting
submodule, in this
case with two such submodules shown at 36. Referring to figure 3, a second
power
supply segment 38 is configured to couple with the first power supply cable
harness 31 to
receive line voltage power therefrom and to deliver low voltage to the
lighting
submodules 36. In this case, the second power supply segment 38 includes a
power
supply 39 and a second power supply cable harness 39a (denoted by the chain
double-
dotted line) extending along the second length dimension L2 of the lighting
subzone 32 to
deliver lower voltage power to each of the lighting submodules 36.
10094] Referring to figure 2, the first power supply cable harness 31 is
thus
configured in a first mode to deliver line voltage power to the at least one
lighting module
22, and in a second mode (figure 3) to cooperate with the second power supply
segment
38 in the at least one track lighting module 24 to deliver line voltage power
to the second
power supply 39, which in turn is configured to deliver low voltage to the at
least one
lighting submodule 36 via the second power supply cable harness 39a.

100951 Referring to figure 3, also provided is at least one hub segment 40
to join with
at least two of the housing segments 18 to form a designated grid
configuration. As
shown in figure 3, the hub segment 40 may also be coupled with the line drop
12 which
may include a support cable, or a stem structure with a IA" (or other)
diameter stern
structure, as an example. Examples of the hub segment 40 and housing segments
18 may
be found in co-pending U.S. Pat. App. No. 16/795,153, filed February 19, 2020
and
entitled COUPLERS FOR LIGHT FIXTURES, related U.S. Pat. App. No. 15/299,168,
filed October 20, 2016, now granted as U.S. Pat. No. 10,215,380, and related
U.S. Pat.
App. No. 16/256,356, filed January 24, 2019, now granted as U.S. Pat. No.
10,584,857,
the entire subject matter of both of which is incorporated herein by
reference.
[0096] Referring to figures 2, 3, 4, 8 and 9, in some example embodiments,
the first
power supply cable harness 31 may include a power line extending along the
housing
with each of a plurality of line voltage outlet plugs 44 (figure 3) located on
a
corresponding cable 48, which may be joined to the supply line 14 and spaced
along the
first length dimension Ll, for connection to a complementary line voltage
inlet plug 46
located on a corresponding cable 49. The cable 49 may extend from the track
lighting
module 24 (as shown in figures 3 and 9) to be an input to the second power
supply 39, or
to extend from the non-track lighting module 26 (as shown in figures 4 and 8).
Thus, with
reference to figure 3, a group of line voltage outlet plugs 44 may each be
mounted on a
corresponding cable 48 (not shown) to engage a matching line voltage inlet
plug 46 on a
corresponding cable 49 in the corresponding track lighting module 24, or non-
track
lighting module 26. The number of line voltage outlet plugs 44 can thus be
configured
as part of a kit, as will be described.
[0097] Referring to figures 3 and 9, in some example embodiments, each of
the one
or more lighting submodules 36 may be configured to include a class 2 driver
50, while
the second power supply 39 may thus be configured to deliver substantially
constant
voltage thereto, while the driver 50 may be configured to adjust the
illumination of the
lighting submodule 36 by stepping down the voltage delivered thereto. As shown
in
figure 9, the second supply cable harness 39a may include a number of
conductive paths
AXS-SYX2/CDA 20
Date Recue/Date Received 2021-02-23
provided by exposed cables extending along opposite boundaries of the subzone.
For
example, the exposed cables 51a may be configured to present substantially
constant
voltage along the second passage 39, while exposed cables 51 b may he
configured as a
part of a wired communications network channel to deliver commands to set the
power
level of the driver 50, as will be described. The wired communications network
channel
may thus originate from a corresponding number of strands 46a, 46b of cable 49
coupled
to the inlet plug 46, or wired communications channel separate therefrom.
[0098] Referring to figures 4 and 8, in some example embodiments, each of
the non-
track lighting modules 26 may include a constant current driver 52, and the
first power
supply cable harness 31 may be configured to deliver line voltage power
thereto.
Similarly, the constant current driver 52 may be controlled by way of a wired
communications network channel originating from a corresponding number of
strands
46a, 46b of cable 49 coupled to the inlet plug 46, or another wired or
wireless
communications channel separate therefrom.
[0099] Referring to figures 2 and 4, some example embodiments may be
provided in
the form of a kit for assembling a grid lighting network or grid network shown
in part at
54, The kit may comprise a first plurality of housing (or grid) segments 18
configured to
be assembled to form the grid network 54, by way of a plurality of hub
segments 40, to
define a second plurality of mounting sectors 56 in lighting zone 20 for
supporting each
of a third plurality of lighting modules 22, which in the case of grid
lighting system 10
may be defined along the first passage 28. In the case of figure 2, each of
the track
lighting module 24 and/or the non-track lighting module 26 may have a second
length
dimension L2 equal to or approximating the first length dimension Li of the
corresponding housing segment 18, which may mean that each housing segment 18
may
have one such mounting sector 56. In other example embodiments, where the
track
lighting modules 24 and/or the non-track lighting modules 26 may have a
shorter length
than the corresponding housing segment 18, the latter may provide more such
mounting
sectors 56 as the case may be. In still other example embodiments, the
dimensions of the
mounting sectors 56 may not be particularly relevant in respect of the
dimensions of a
corresponding track or non-track lighting module, for example if the latter is
a pendant.
AXS-SYX2(CDA 21
Date Recue/Date Received 2021-02-23
100100] The kit may also comprise at least one first power supply segment 30
(such as
in the form of the first power supply cabling harness 31) to be coupled to a
first line
voltage outlet, such as the circuit breaker 16, to deliver line voltage power
to each of the
mounting sectors 56 in at least one first power delivery zone 58 in the grid
lighting
network 54. The first power supply cabling harness 31 may be formed by
individual
segments installed in each corresponding housing segment 18, and configured to
be in
communication with one another throughout the mounting sector 56 of the grid
lighting
network 54 to be supplied by the supply line 14, by way of electrical
connections made
between such individual housing segments 18 at each corresponding hub segment
40. In
other example embodiments, the first power supply cabling harness 31 may be
installed
in the corresponding mounting sector 56 of the grid lighting network 54 once
assembled.
100101] The first power delivery zone 20 may thus be defined by:
i. a designated number of the mounting sectors 56; and
ii. a designated number of the lighting modules 22, each configured
for mounting in the first power delivery zone 58 at one of the
designated number of mounting sectors 56.
100102] In some example embodiments, the first power delivery zone 58 may also
be
defined by a designated number of the grid segments 18.
[00103] The first power delivery zone 58 may be configured according to a
first
combined lighting unit power rating for the first power delivery zone 58 to
approach but
not exceed a maximum power delivery rating of the first line voltage outlet,
such as the
current breaker 16, to enable any one of the designated number of mounting
lighting
modules 22 to be moved from one of the mounting sectors 56 to another mounting
sector
56 in the designated number thereof, and still comply with the maximum power
delivery
rating of the first line voltage outlet.
1001041 Thus, in some example embodiments, a single delivery zone 58 powered
by
the circuit breaker 16, may be configured to approach but not exceed a maximum
power
AX5-SYX2/CDA 22
Date Recue/Date Received 2021-02-23
delivery rating of a first line voltage outlet, such as the current breaker
16. In other
example embodiments, a plurality of delivery zones 58 may be powered by the
circuit
breaker 16, in which case the plurality of power delivery zones 58 may be
configured to .
approach but not exceed a combined maximum power delivery rating of the
current
breaker 16.
[00105] In some example embodiments, the designated number of lighting modules
22
may be selected from one or more track lighting modules 24 and/or one or more
non-
track lighting modules 26.
[00106] In some example embodiments, a method may be provided to prepare a
configured installation of a grid lighting network installation in a target
space, with a
designated space, such as an interior space, and/or a designated purpose or
function. The
present method may allow for the grid lighting network installation to be
reconfigured
after the original installation should the primary interior space or a portion
thereof, and/or
designated purpose or a portion thereof change following original
installation. While an
interior space is referred to herein it should be understood that the present
structures and
functions will also perform in a substantially similarly if not in an
identical manner in an
exterior setting, combination of interior and exterior, or other settings.
[00107] A first step may be to provide a plurality of grid segments 18 which
are each
configured to be assembled into the grid lighting network 54 for supporting
each of a
plurality of interchangeable lighting modules 22 at a corresponding one of a
plurality of
mounting sectors 56 defined on the grid lighting network 54. Next, the
plurality of grid
segments 18 may be allocated to at least a first power delivery zone 58,
defined by:
i. a corresponding designated number of mounting sectors 56 along
the designated first power delivery zone 58; and
ii. a designated number of the interchangeable lighting modules 22,
each for mounting at any one of the designated first number of
mounting sectors 56 in the first designated power delivery zone 58.
AXS-SYX2/CIDA 23
Date Recue/Date Received 2021-02-23
[00108] Another step may be to provide at least one first power supply, such
as first
power supply segment 31, to be coupled to a first line voltage outlet, such as
one or more
outlet plugs 44, to deliver line voltage power to each of the number of
mounting sectors
56 in the first power delivery zone 58.
[00109] Another step may be to configure the designated number of mounting
sectors
56 in the first power delivery zone 58 according to a first combined lighting
unit power
rating for the first power delivery zone 58 to approach, but not exceed, a
maximum power
delivery rating of the first line voltage outlet, such as one or more outlet
plugs 44. This
step may thus enable any one of the designated number of lighting modules 22
to be
moved from one mounting sector 56 of the designated number to another mounting
sector
56 thereof, and still comply with the maximum power delivery rating of the
first line
voltage outlet.
[00110] Another step may be to select the designated number of interchangeable
lighting modules 22 from one or more track lighting modules 24, or one or more
non-
track lighting modules 26.
[00111] Figure 5 shows another example embodiment of a housing segment 60
which
is configured to be assembled to form the grid network 54 as discussed herein.
The
housing segment 60 has a direct lighting zone 62 and an oppositely oriented
indirect
lighting zone 64, which in this case is opposite the direct lighting zone.
Each zone 62, 64
extends along a length dimension of the housing segment 60 and includes a
corresponding passage 66, 68 to receive one or more lighting modules therein,
such as
those shown collectively at 70.
[00112] The collection of lighting modules 70 may include at least one track
lighting
module 72 and at least one non-track lighting module 74. In the case, the
collection of
lighting modules 70 includes a number of different lighting configurations
among the
many that may be used. Each track lighting module 72 therein, in this example,
may
AXS-SYX2/CDA 24
Date Recue/Date Received 2021-02-23
include a constant voltage driver 76, while the non-track lighting module 74
may include
a constant current driver 78.
[00113] Each of the lighting modules in the collection 70 may be further
configured
into, or be selected from, a direct group 80 and an indirect group 82, wherein
each has a
housing structure 84, 86 which may be configured to fit exclusively in its
corresponding
direct passage 66 or indirect passage 68 respectively. For instance, each
lighting module
in the direct group 80 may be provided with at least one dimension and/or
formation
which differs from a corresponding at least one dimension and/or formation of
each
lighting module in the indirect group 82.
[00114] In the case of the lighting modules in direct group 80 of figure 5,
each may
have a pair of side wall sections 88 which are longer (or shorter) in vertical
section and
may be provided with one or more surface formations such as recesses 90a, 90h.
Meanwhile, each of the lighting modules in indirect group 82 may have a pair
of sidewall
sections 92 which are shorter (or longer) in vertical section and may be
provided with one
or more surface formations such projections 94. The indirect group 80 and
direct group
82 each includes end wall sections 81 and 83 to be used in place of a
corresponding
lighting module in some examples.
[00115] Figure 6 shows example embodiments of a housing segment 60 secured to
an
anchor structure 96 such as any such structures disclosed and shown in co-
pending U.S.
Pat, App. Nos. 62/820,083 filed March 18, 2019 and 16/723,665 filed December
20,
2019, both entitled MOUNT INTERFACE FOR LIGHT FIXTURES, the entire subject
matter of both of which is incorporated herein by reference. Figure 7 shows
example
embodiments of lighting modules collectively at 98.
[00116] Figures 10 to 14 show another grid lighting network 100, having a
first
plurality of grid segments 102, each of which may be configured to be
assembled to form
the grid lighting network 100 and to define a second plurality of mounting
sectors, with
several such mounting sectors shown at 104. Each mounting sector 104 may be
AXS-SYX2/CDA 25
Date Recue/Date Received 2021-02-23
configured to operatively couple with a corresponding one of a third plurality
of lighting
modules 106.
[00117] At least one first power supply segment 110 may be provided which may
be
configured to be associated with the grid lighting network 100 and to be
coupled to a first
line voltage outlet as shown schematically at 112, via one of a plurality of
stem structures
114, to deliver line voltage power to each of the mounting sectors 104 in at
least one first
power delivery zone generally shown at 118. In this case, the at least one
first power
delivery zone 118 may be defined by a designated first number of the second
plurality of
mounting sectors 104; and a designated first number of the third plurality of
lighting
modules 106.
[00118] The at least one first power delivery zone 118 may be configured
according to
a first combined lighting unit power rating for the first power delivery zone
118 to
approach, but not exceed, a maximum power delivery rating of the first line
voltage outlet
112, to enable any one of the designated first number of lighting modules 106
to be
moved from one of the mounting sectors 104 in the designated first number
thereof to
another of the mounting sectors 104 in the designated first number thereof,
and still
comply with the maximum power delivery rating of the first line voltage outlet
112.
Referring to figure 12, the designated first number of lighting modules 106
may be
selected from one or more track lighting modules 120 and/or one or more non-
track
lighting modules 122.
[00119] A plurality of hub segments 124, such as those disclosed in example
embodiments in the present disclosure, may be provided to couple the first
plurality of
grid segments 102 together to form the grid lighting network 100. The hub
segments 124
may be in the form of standardized or non-standard hub segments for

segment
142 may be configured to deliver the low voltage at a voltage of about 12 to
about 48
volts at 60 watts (or at another level according to the one or more
configurations or
attributes of the grid lighting network 100 or components thereof).
[00128] The at least one first power supply segment 110 may further comprise a
plurality of the first power supply segments 110, with each integrated into a
corresponding grid segment 102, while each of the first power supply segments
110 may
be configured to be electrically coupled with one or more adjacent first power
