on-off state and conveying light from the light source through a visible
surface
area of the wiring device by a lens or transparent material and where the
device
is concealed behind a standard cover plate.
[0008] U.S. Patent No. 7,118,235 to Barton is a continuation-in-part of the
'469 patent and discloses a lighting device having a housing with an

central
portion 32 on the front face 22 of the housing 12 and the cover 16 between the
two sets of blade apertures 24. In the embodiment shown, the central portion
32 is recessed with respect to the end portions 25. The central portion 32
between the blade apertures 24 has a substantially planar surface with
openings for a test button 34 and a reset button 36 of the GFCI circuit 38.
Preferably the central portion 32 is located so that the plugs when connected
to
the sets of blade apertures 24 do not overlie the central portion 32 to block
light from the light source. The cover 16 is also provided with openings 40
for
indicator light pipes 42 which are operatively connected to indicator lights
on
the printed circuit board 44 to indicate the proper operation of the GFCI as
shown in Fig. 1.
[0040] An indicator light is provided on one side of the cover 22 and circuit
board 44 to indicate power is supplied to the receptacle and an indicator
light
is provided on the opposite side to indicate the GFCI circuit is tripped. The
indicator lights are connected to the electrical circuitry of the GFCI to
provide a
visual indication to the user of the operating status of the GFCI circuit. The
light pipes 42 extend from the respective indicator lights to the front face
22 of
the cover 16. In the embodiment shown, the light pipes 42 have a rounded top
face that is oriented substantially flush with the front face of the cover so
that
the light projected by the light pipes can be observed by the user.
[0041] The electrical components of the GFCI circuit 38 as shown in Fig. 2
and Fig. 3 include the printed circuit board 44 that is mounted within the
internal cavity 20 of the housing 12. In the embodiment shown in Fig. 2, the
printed circuit board 44 is attached to the base 14 in a central portion of
the
base below the central portion 32 of the cover 16 and between the electrical
contacts and the shutter mechanisms 26. The circuit board 44 includes
suitable circuitry to operate the GFCI as known in the art. In the embodiment

shown, the test button 34, reset button 36 and indicator lights 42 are mounted
on or above the circuit board 44 and extend outwardly through the respective
openings in the front face 22 of the cover 16.
[0042] A photo sensor 46, light sensor or photo cell is coupled to the circuit
board 44 on a first side 48 and at least one and preferably two light sources
shown as LEDs 50 are mounted on a second side 52 opposite the first side 48.
The photo sensor 46 can be a known photo cell or sensor capable of measuring
ambient light and actuating the light source when the ambient light is below a
predetermined threshold level. As shown in Fig. 1 and Fig. 2 the photo sensor
46 is positioned along the side edge 48 of the circuit board 44 and along a
longitudinal side edge 53 of the front face 22 of the central portion 32 and
between the two sets of the blade apertures 24. Preferably the photo sensor 46
is spaced outwardly from the test button 34 and reset button 36 toward the
side edge 53 of the cover 16 and outwardly from the blade apertures 24.
[0043] In preferred embodiments of the invention, the light sources are two
LEDs mounted directly to the circuit board 44 although other light sources can
be used. Preferably two LEDs 50 are mounted on the same side of the circuit
board 44 and opposite the photo sensor 46 so that the light from the LEDs 50
does not interfere with the photo sensor 46 to reduce the risk of a possible
false
indicator of the ambient light level. The photo sensor 46 measures the ambient
light level in the area of use and is operatively connected to the circuit
board 44
and the LEDs 50 to actuate and illuminate the LEDs 50 when the ambient light
level is below a threshold level.
[0044] A light conducting member 54 functioning as a light pipe is provided
to direct the ambient light to the photo sensor 46. In one embodiment, the
light conducting member 54 is coupled to the cover 16 so that the light
conducting member 54 extends through an opening 56 in the cover 16. In the
embodiment shown, the light conducting member 54 has a substantially
cylindrical shape extending between the photo sensor 46 and the front face 22
CA 2827473 2019-10-09

CA 02827473 2013-09-18
- 12 -
of the cover 16. The light conducting member 54 has a longitudinal length so
that the flat top face 58 is substantially flush with the front face 22 of the
cover
16. Alternatively the top face 58 can be positioned a slight distance outward
from the front face 22 or can be recessed with respect to the front face 22.
The
opening 56 for the light conducting member 54 has a frustoconical shaped
surface at the front face 22 to form a beveled edge and a conical shaped
recess
60 around the top edge of the light conducting member 54 to enable ambient
light to enter the light conducting member 54 through the top face 58 and the
upper side surface 62 of the light conducting member 54.
[0045] In the embodiment shown in Fig. 6 and Fig. 7, the light conducting
member 54 has a bottom end with a concave bottom surface 64 forming a
recess opposite the top face 58. The concave bottom surface 64 is positioned
directly above the photo sensor 46 as shown in Fig. 7. The concave bottom
surface 64 of the light conducting member 54 is positioned sufficiently close
to
the photo sensor 46 to transmit ambient light from the area around the wiring
device 10 to the photo sensor 46. The photo sensor 46 includes wires 66
connected to the circuit board 44 or other electrical controls to actuate the
LEDs 50.
[0046] The cylindrical side surface of the light conducting member 54 has an
annular recess 68. The inner surface of the opening 56 and the cover 16 has a
detent 70 shown as an annular rib extending radially inwardly with respect to
the opening 56 for cooperating with the annular recess 68 of the light
conducting member 54 to capture and couple the light conducting member 54
to the cover 16. The detent 70 is received in the recess as shown in Fig. 7 by
inserting the light conducting member 54 into the opening 56 from the bottom
side of the cover 16. As shown in Fig. 7, the bottom edge of the opening 56
has
an angled surface forming a beveled to guide the light conducting member 54
and slide over the detent 70 to snap into the opening 56.

- 13 -
[0047] Each of the LEDs 50 is provided with a light conducting member 72
to project the light from the LED in a selected direction as shown in Figs. 4
and
5. The light conducting members 72 define a light transmitting member for
emitting a light beam from the end of the light conducting members 72 to a
target area. The cover 16 includes openings 74 extending between the front
face 22 and the rear inner face 23 for receiving the light conducting members
72 to enable the light conducting members 72 to extend through the front face
22 of the cover 16 and rotate within the opening 74. In the embodiment shown
in Fig. 1, the two light conducting members 72 are provided in the central
portion 32 on one side of the test button 34 and reset button 36 and along a
side edge 76 of the cover 16. In one embodiment, the light conducting
members 72 are spaced outwardly from the blade apertures 24 toward the side
edge 76. In other embodiments, the light conducting members 72 can be
positioned on opposite sides of the buttons and central portion 32. It is
generally preferred to have the light conducting members 72 on the same side
76 of the housing and cover 16 and the photo sensor on an opposite side 78 to
avoid interference and reduce the possibility of false indications of the
ambient
light level. In other embodiments the light conducting members can be
positioned in other suitable locations on the front face of the electrical
wiring
device.
[0048] Referring to Fig. 4, each light conducting member 72 has a
substantially cylindrical shape with a longitudinal axis extending between a
bottom inner face 80 and a top outer face 82. In the embodiment shown in
Figs. 8 and 9, the bottom inner face 80 is substantially flat and is
positioned
directly above the respective LED 50 to receive light from the LED and
transmit
the light along the longitudinal axis to the top outer face 82 where the light
is
projected outwardly. The light conducting members 72 define a light pipe and
light transmitting member for carrying the light from the LED and projecting a
light beam outwardly from the wiring device 10 in a predetermined direction.

[0049] The side surface 84 of the light conducting member 72 includes an
annular recess 86 forming a bottom edge 88 and a top edge 90. As shown in
Figs. 5, 8 and 9 the opening 74 in the cover 16 has an inwardly extending
detent 92 that is received within the annular recess 86 between the bottom
edge 88 and the top edge 90 to attach the light conducting member 72 to the
cover 16. In the embodiment shown the detent 92 is a continuous annular rib
extending radially inwardly from the side wall of the opening 74 to engage the
annular recess 86 of the light conducting member 72. The light conducting
member 72 is mounted to the cover 16 for rotational adjustment with respect
to the cover 16 as indicated by arrows 100 in Fig. 1. The light conducting
member 72 can be manually rotated about the longitudinal axis to direct the
light emitted from the light conducting member in a selected direction.
Preferably each of the light conducting members rotates independently of the
other.
[0050] The outer top end of the light conducting member 72 has an inclined
face 94 forming a light projecting surface that is oriented at an incline with
respect to the longitudinal axis of the light conducting member and at an
incline with respect to the plane of the cover 16 as shown in Fig. 9 to
project a
light in a direction outwardly from the plane of the inclined top face 94 as
indicated by arrows 102 in Figs. 8 and 9. In the embodiment shown, the light
is projected from the light conducting member 72 substantially perpendicular
to the plane of the inclined face 94.The top outer face 82 is a minor surface
area relative to the surface area of the inclined face 94 and is oriented
substantially perpendicular to the longitudinal axis of the light conducting
member and parallel to the plane of the front face 22.
[0051] The inclined face 94 in the embodiment shown is oriented at an acute
angle of about 30 with respect to the front face 22 of the cover and at an
angle
of about 600 with respect to the longitudinal axis of the light conducting
member 74. The angle of the inclined face 94 can be selected depending on the

CA 02827473 2013-09-18
- 15 -
desired projecting angle of the light beam and the shape of the face 94. The
light conducting member 72 functions is a light pipe to direct the light from
the
LED 50 outwardly from the front face 22 of the cover 16 at an inclined angle
with respect to the front face 22. The inclined face 94 is shown as being
substantially flat. In alternative embodiments, the inclined face can be
curved
to form a convex surface to define lens for focusing the light or a concave
surface. In further embodiments, the outer face of the light conducting
members 72 can have other suitable shapes with one or more surfaces capable
of projecting a beam of light in a selected direction so that adjusting the
position of the light conducting members enable focusing the light beam to a
selected target area.
[0052] The opening 74 for the light conducting member 72 has a top end
with an inclined surface 96 forming a conical shaped recess adjacent the front
face 22 surrounding the light conducting member 72. The top face 82 of the
light conducting member 72 in one embodiment shown in Fig. 5 extends a
slight distance above the front face 22 a distance to enable the light to be
projected away from the front face 22 and to allow the user to manually grip
the top end and manually rotate the light conducting member 72 to orient the
inclined surface 96 in a selected direction thereby projecting the light beam
to
a desired target area.
[0053] During use, the device 10 is mounted in a standard electrical box and
coupled to the power source to provide electrical power to the electrical
contacts and components of the device. The photo sensor detects the ambient
light levels and produces a signal to actuate the LEDs 50 when the light level
is
below a predetermined level. The user is able to rotate each of the light
conducting members 72 of the light emitting assembly independently of each
other to position the outer face in a desired orientation, thereby projecting
light
from each light conducting member 72 in a selected direction to illuminate a
selected target area. Each of the light conducting members is independently

CA 02827473 2013-09-18
- 16 -
adjustable to direct the light in selected patterns or areas as depicted in
Fig.
10. For example, the device can be mounted on a wall as shown in Fig. 10 so
that the light conducting members can be oriented to direct a light beam 104
downwardly toward the floor or to one side toward a doorway. The LEDs 50
and the light conducting members 72 are able to project a light beam with
sufficient brightness and intensity to illuminate a target area.
[0054] While various embodiments have been selected to illustrate the
invention, it will be understood by those skilled in the art that various
changes
and modifications may be made without departing from the scope of the
invention.
