FIELD OF THE DISCLOSURE
[0002] The present disclosure relates to luminaire structures and
associated
structures.
BACKGROUND
[0003] Wall- and ceiling- mounted luminaires are typically mounted to walls
and
ceilings and configured so present emitted light either in a direct or
indirect light
distribution mode. However, such mounted luminaires are often limited to one
such
mount configuration, in other words, they arc configured for mounting on a
wall or
ceiling, but not both, and when so mounted arc usually confined to one light
distribution
mode.
[0004] It would thus be desirable to provide novel approaches for the
mounting of
light fixtures, or at least to provide the public with one or more useful
alternatives.

[0069] Referring to the figures, there is provided a luminaire assembly 10
comprising
a track structure 12 mountable on an enclosure surface such as wall surface
shown at 14,
and a pair of luminaire structures 16 for positioning on the track structure
12, along a
longitudinal axis "A". While the luminaire assembly 10 and other example
embodiments herein are described as having longitudinal features and
structures, the
present disclosure encompasses other non-longitudinal example embodiments
and/or
variations of such features and structures which may not, in some cases, be
longitudinal.
[0070] Referring to figures 2 and 3, the track structure 12 has an
anchoring surface
region 18 configured for securing to the wall surface 14, at a plurality of
designated
AXS-CTI 3/CDA 12
CA 3058841 2019-10-17
locations with one shown at 20, and a first mounting surface region 22. The
first
mounting surface region 22 is configured to form a mount interface shown at
26, along a
longitudinal axis A, with a corresponding aligned second mounting surface
region 30 on
the luminaire structure 16 in a luminaire installation as shown generally at

[0071] The luminaire structure 16 includes a housing structure 32 which
defines the
corresponding second mounting surface region 30. An illumination structure 36
extends
outwardly from the housing structure 32, with opposed outer surface regions
38, 40
which terminate at a longitudinal distal end region 42.
[0072] The housing structure 32 comprises an elongate wall mounting segment
44
extending along the luminaire structure 16, at least in part, and which

26.
[0076] In some example embodiments, as shown in figure 8, the track
structure 12
and luminaire structure 16 may be configured to provide visual continuity
along visible
surfaces thereon in the first mode when viewed from a user space defined by
the wall
surface 14 and, if desired, on either side of the luminaire structure 16. In
this case, the
track structure 12 and luminaire structure 16 may be configured to minimize,
if not
block, light emitted by the illumination structure 36 from leaking between
them, either
from above or below the luminaire structure 16, as viewed in figure 8, and
along the
mount interface 26. This is provided, in one example, by the several points of
contact
along the first mounting region 22 and the second mounting region 30, which
collectively
serve to provide a substantially continuous light barrier along the
longitudinal axis A.
[0077] Referring to figures 2 and 3, the elongate wall mounting segment 44
includes
an inner support structure 52 with a plurality of passages 54 to receive a
corresponding
plurality of first fasteners 56 held in the track structure 12 to secure the

(accommodate) the designated locations of the passages 54 according to the
designated
position of the luminaire structure 16 on the wall surface 14.
[0080] In some example embodiments, as shown in figures 2 and 8, the
elongate wall
mounting segment 44, elongate supporting segment 46 and/or elongate light
source
segment 50 may include complementary coupling locations 64 to be coupled in
the first
mode, and held in place by second fasteners 66. In this case, the second outer
casing
structure 60 may be configured to cover the coupling locations 64 in the first
mode, at
least in part.
[0081] In some example embodiments, as shown in figure 2 and 8, the
elongate
supporting segment 46 may be configured to support a light guide 68 in an
optical
coupling configuration with the light source segment 50. In this case, the
elongate light
source segment 50 is removable from the elongate support element 46 in the
second
mode, as seen in figure 6.
[0082] Referring to figures 2 and 7, the light source segment 50 may
include one or
more LED arrays 70 orientable along a longitudinal axis A extending along the
light
guide 68, along with a power supply shown at 72 for operative coupling to the
one or
more LED arrays 70. An individual LED is shown at 70a in figures 2 and 8
aligned with
a longitudinal light guide boundary of the light guide 68.
100831 Referring to figures 7 and 8, the elongate light source segment 50
may include
a light source frame 74 with a first frame portion 76 which is securable to
the elongate
supporting segment 46 to support the elongate light source segment 50 and to
cooperate
therewith to define the coupling locations 64, while a second upright frame
portion 78
may be configured to releasably support the one or more LED arrays 70
releasably
secured thereto.
[0084] In some example embodiments, as shown in figure 2, the outer casing
structure 60 may be held between the elongate wall mounting segment 44 and the
elongate supporting segment 46. The outer casing structure 60 may include a
pair of
AXS-C 3/CDA 15

opposed longitudinal end regions 60a, 60b, at least one of which may be
releasably
clipped to the corresponding elongate wall mounting segment 44 and/or the
elongate
supporting segment 46 for removal therefrom. In this case, the longitudinal
end region
60a may be provided with a catch 80a to engage a complementary catch 80b.
[0085] In some example embodiments, as shown in figures 3, 4, 7 and 8, the
light
guide 68 has opposed inner and outer longitudinal light guide boundaries shown
generally at 82, 84 and opposed lateral light guide boundaries shown generally
at 86, 88.
The elongate supporting segment 46 may be provided with a distal end region 90
(figure

light guide clamp member 94 (figures 7 and 8) may also be provided with a
corresponding end region 94a to engage and releasably secure an opposite side
of the
corresponding inner longitudinal light guide boundary 82 relative to the
elongate support
segment 46. In this case, the light guide clamp member 94 may be releasably
secured to
the elongate light source segment 50 by way of third fasteners 96.
[0086] In some example embodiments, as shown in figures 3, 4 and 8, the
luminaire
structure 16 may further include at least one, in this case a pair of lateral
end cap
segments 98 to engage a corresponding lateral light guide boundary 86, 88 and,
if desired,
at least one longitudinal end cap segment 100 to engage the outer longitudinal
light guide
boundary 84. As shown in figure 8, the longitudinal cap segment 100 may be
provided
with an opening or slot 102 to receive the corresponding longitudinal light
guide
boundary 84.
[0087] In some example embodiments, as shown in figure 8, the light guide
68 may
be further provided with shielding panels 104a, 104b to ensure an efficient
transmission
of light both at the optical coupling 110 and at the inner longitudinal light
guide boundary
82 with the LED array 70, and at the outer longitudinal light guide boundary
84. In this
case, the clamp member 94 may cooperate with shielding panels 104a. 104b, to
minimize
light loss (leakage) at those corresponding locations.

corresponding catches 80a and 80b. Alternatively, the outer panel 106 may be
removed
from the outer casing structure 60 by flexing the outer panel 106 to releasing
the outer
panel from the notched couplings 112. In some example embodiments, one or both
of the
outer panels may be provided in the form of lenses, or may provide other
configurations
to emit light, such as by the way of louvers or the like. The outer panels may
also be
provided with other decorative or acoustic features, such as by the way of
finished
surfaces such as perforated surfaces, or be provided with fabric coverings or
other
acoustic effects.
[0089] Figures 9 and 10 illustrate another luminaire installation shown at
116 in a
reverse configuration to luminaire installation 24, with the in a generally
laterally
horizontally extending luminaire structure 118.
100901 Figures 11 to 13 are fragmentary perspective views of other example
embodiments of luminaire installations 120 and 122 respectively. The luminaire
installation 122 of figure 12 includes a luminaire assembly 124 with proximal
end region
130 of a luminaire structure 126, and a track structure 128 on a wall surface
130. Figure
13 shows a distal end region 131 of the luminaire structure 126, while figures
14 to 17
show the disassembly of the luminaire structure 126.
[0091] Referring to figure 14, the outer casing structure 132 and the outer
panel 134
may be removed to reveal the inner support structure 136 and the fasteners 138
holding
the inner support structure 136 to the track structure 128. Next, as shown in
figure 15,
Axs-c I L3/CDA 17
CA 3058841 2019-10-17
the power supply 140 of the elongate light source segment 142 may be removed
from the
inner support structure 136 by removing fasteners 144. Next as shown in figure
16, the
light source frame 146 may be removed from the inner support structure 136 by
removal
of fasteners 148, and in figure 17, the LED array 150 may be removed from the
light
source frame 146 by way of fasteners 152, thus allowing servicing of the
elongate light
source segment 142 and the LED array 150, as well as the other structures and
components revealed by the removal of the cover segment outer casing structure
132 and
the outer panel 134, while thc inner support structure 136 remains fastened to
the track
structure 128. In some cases such as this case, the power supply 140 may be
removed to
gain access to the fasteners 148.
[0092] In some example embodiments, as shown in figures 1 and 2, the
luminaire
assembly 10 is shown to include two luminaire structures 16, with the opposed
outer
surface regions 38, 40 defined on outer panels 106, 108. Figures 18 and 19
show further
details of the lateral end cap segment 98, which, as will be described, may be
configured
to clamp, or otherwise hold, outer panels 106 and 108 and/or the light guide
68 (figure
8), or to close the outer cross section of the luminaire structure 16, so as
to conceal the
support arm 178 and the associated fasteners and the like.
[0093] In some example embodiments, as shown in figure 20, each of the
outer
panels 106, 108 has a lateral edge which terminates at an adjacent lateral end
region 162,
164. Also provided is a clamp assembly shown at 160 for engaging the adjacent
lateral
end regions 162, 164 to providing an aligning interface 170. The clamp
assembly may
provide a pair of outer surfaces 166. 168 which may be configured to be
substantially
coplanar with the outer surface regions 38, 40 of the outer panels 106, 108 at
the aligning
interface 170 (figures 21 and 21a).
[0094] In some example embodiments, as seen in figures 20 to 23, the clamp
assembly may include a pair of clamp elements 172, 174 to extend along
opposite outer
boundaries of the luminaire structures 16, and are configured to be drawn to
one another
AXS-CTL3/CDA 18
CA 3058841 2019-10-17
to form the aligning interface 170, by way of fasteners 176, to extend through
the upper
of the clamp elements 172 and be each received in corresponding receptors 177.
[0095] In some example embodiments, along each lateral edge region of the
respective luminaire structure 16, a support arm 178 may extend therealong
between the
housing structure and the distal end region, and configured to engage each of
the mating
clamp elements 172, 174 in the aligning interface 170. In this case, the
support arm 178
may be provided with a proximal end region 178a which extends into the housing
structure 32 through the spacing between the distal end region 90 of the
elongate
supporting segment 46 and the outer casing structure 60. Referring to figure
19, the
support arms 78 may be provided with an anchoring flange 178a extending
longitudinally
relative to the axis A with a passage 178b to be held by one of the first
fasteners 56.
Other configurations may be provided to secure the support arm to the housing
structure,
or to the track structure, if desired.
[0096] In some example embodiments, as shown in figures 22, 23, each clamp
element 172, 174 may include a pair of opposed first locking formations 180,
182
extending along opposite sides thereof, and each support arm includes a pair
of opposed
second locking formations 184, 186 along opposite sides thereof, wherein each
of the first
locking formations 180, 182 engages a corresponding second formation 184, 186.
[0097] Referring to figures 25 and 26, the first locking formations 180,
182 can be
seen to provide inwardly inwardly facing inclined surfaces 180a, 182a, which
engage
with outwardly facing inclined faces 184a, 186a, as can been in figure 25, to
form a
plurality, in this case four clamping interfaces 188. Thus, the tightening of
the fasteners
176 into the receptors 177 may thus have the effect of drawing each of the
luminaire
structures toward the clamping interfaces 188 to form a unitary luminaire
assembly, while
providing a clean and substantially continuous surface presentation across the
clamping
interfaces, as shown in figure 25 to 27.
AXS-CT1.3iCDA 19
CA 3058841 2019-10-17
[0098] In some example embodiments, as shown in figures 18 and 19, each
lateral
end cap segment 98 may be configured to provide the clamp interfaces in
connection with
a single support arm 178. In this case, the lateral end clamp segment may be
provided
with lateral end cap elements 190 and 192, each with a corresponding locking
formation
194 to engage a corresponding second locking formation 196 of the pair
provided on the
support arm 178. Further, the lateral end cap segments may provide a provide
other
locking interfaces with the support arm 178 by way of notches 198a and posts
198b
formed in the support arm 178 and the upper end cap element 190 and, if
desired, a
different set of notches 200a and posts 200b formed in the support arm 178 and
the lower
end cap element 192 for lateral locking alignment.
100991 In another example embodiment, as seen in figures 8, 20. and 21,
each of the
support arms 178 may provide a set of notches 202 to receive corresponding
ends of the
longitudinal end cap segment 100, in other words so that the support arm may
fit through
the opening 102, so as to positively locate the longitudinal end cap segment
100 with the
lateral end cap segment 98 to form another pair of notched couplings 112.
Passages 204
may be further provided to receive fasteners 206 to thread into receptors 208
in the
longitudinal end cap segment 100 These locking configurations may provide, in
some
example embodiments, a means by which the luminaire assembly may present
substantially unitary and/or continuous surfaces along the length of the
luminaire
assembly 10, while enabling the housing structure 32 and the track structure
12 to
accommodate any planar variations in the wall surface.
[00100] In another example embodiment, as seen in figures 28 to 35, a
luminaire
assembly is shown at 210 having a pair of luminaire structures 212 joined at a
corner
segment 214. In this case, the corner segment 214 may be provided with locking
formations, notches and/or posts as used with the end cap segment 98, or other
structures,
to couple the luminaire structures 212 thereto.
