FIELD OF THE DISCLOSURE

[0002] The present disclosure relates to luminaire structures and associated structures.
BACKGROUND

[0003] Traditionally, grid lighting systems deploy a grid of track segments which are configured to deliver power to a collection of lighting modules, to deliver lighting to a space.

[0004] Considerable effort is involved in the installation of such grid lighting systems so that, once installed, the actual configuration of lighting modules can safely be changed by a user. This is done by delivering "low voltage", such as that specified as Class 2 UL, along the entire grid lighting system, to be coupled with "low voltage"
lighting modules.

[0005] In such configurations, each of the track segments is usually supplied with an array of dedicated "low voltage" supply "line drops" appearing at relatively short intervals, such as at every 8 feet, along the grid lighting system. Moreover, each "low voltage" supply line is usually supplied by a "remote" power supply, which may power one or several of such "low voltage" supply lines. This usually requires a dedicated utility space, remote from the grid lighting system itself, to be set aside to locate the power supplies, along with considerable lengths of power cabling to and from each power supply to its one or several designated "low voltage" line drops. Thus, the larger the area occupied by the grid lighting system, the larger the power supply infrastructure required to allow it to function in the manner intended, with a corresponding increasing overhead expense as a result.

DETAILED DESCRIPTION

[00140] 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 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, Date Recue/Date Received 2023-09-05 mechanical or other connections or couplings. The terms upper, lower, and vertical are intended for operative context only and are not necessarily intended to limit the invention only to those configurations or orientations. In any instance in which the disclosure refers to a single instance of an element, example embodiments may include a multiple of such elements. The term "at least one" in reference to any element is not intended to force an interpretation on any other reference elsewhere in the disclosure to a single instance of an element to mean only one such instance of the element.
Furthermore, and as described in subsequent paragraphs, the specific mechanical and/or other configurations illustrated in the drawings are intended to exemplify embodiments of the invention. However, other alternative mechanical and/or other configurations are possible which are considered to be within the teachings of the instant disclosure.
Furthermore, the present disclosure provides basis for and encompasses support for any one element, feature, structure, function, of any aspect and/or example embodiment described in the present disclosure including the figures, clauses and/or claims herein, which is itself claimed on its own or combined with any one or more elements, features, structures, functions, and/or steps from the same or any other aspects and/or example embodiments described in the present disclosure including the figures, clauses and/and claims herein.

[00141] The terms "line voltage" and "line voltage power" used herein 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 from about 2500W at 277V to about 1080W at 120V, or other such voltage levels and/or power levels appearing in power distribution systems in building structures.

[00142] 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 as lighting units, such as 48V at 60W maximum, or other such voltage and power levels specified in residential and commercial building codes.

Date Recue/Date Received 2023-09-05

[00143] 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.

[00144] 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.

[00145] 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.

[00146] 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 Date Recue/Date Received 2023-09-05 other such light sources, equivalents and variants thereof.

[00147] 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.

[00148] 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.

[00149] The term "modular" as it relates to a modular lighting segment structure for use in assembling in a series of at least two thereof for a grid lighting network or system and/or one or more modular junction structures and modular structures used in connection therewith. The term modular may include, but not be limited to constructions with standardized, compatible, and/or complementary dimensions and/or connectivity, enabling the associated segments, structures and the like to be capable to being used in different configurations. For example such configurations may be achieved by the use of standardized, compatible, and/or complementary connectors sets, or connectors capable of being joined with adjacent complementary connectors for the purposes of assembling such grid lighting network or system.

[00150] Figure 1 shows a prior art version of a grid lighting system A, having 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 Date Recue/Date Received 2023-09-05 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 PS1 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 this case between each circuit breaker CB and the corresponding power supply PS.)

[00151] 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 stem 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 12a 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.

[00152] 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.

Date Recue/Date Received 2023-09-05

[00153] 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, 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.

[00154] 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.

[00155] 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.

Date Recue/Date Received 2023-09-05

[00156] 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.

[00157] 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 1/2" (or other) diameter stem 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.

[00158] 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 (or wire in terminals) 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 Li, for connection to a complementary line voltage inlet plug (or wire in terminal) 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.

Date Recue/Date Received 2023-09-05

[00159] 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 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 5 lb may be 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.

[00160] 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.

[00161] 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 Ll of the corresponding housing segment 18, which may mean that each housing segment 18 may Date Recue/Date Received 2023-09-05 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.

[00162] 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.

[00163] 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.

[00164] In some example embodiments, the first power delivery zone 58 may also be defined by a designated number of the grid segments 18.

[00165] 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 Date Recue/Date Received 2023-09-05 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.

[00166] 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 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.

[00167] In some example embodiments, the designated number of lighting modules may be selected from one or more track lighting modules 24 and/or one or more non-track lighting modules 26.

[00168] 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.

[00169] 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:

[00172] 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.

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.

[00180] 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.

[00181] 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 Date Recue/Date Received 2023-09-05 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 interconnecting the grid segments 102.

[00182] In this case, the grid lighting network 100 may be formed from a kit which may be configured to include the first number of lighting modules 106, or be configured for the first number of lighting modules 106, or one or more thereof, to be supplied separately. The at least one first power supply segment 110 may include one or more line voltage outlet plugs 126 spaced along each mounting sector of the designated first number thereof.

[00186] Each non-track lighting module 122 may further comprise a first power controller segment 148 for controlling a first power level of output power to be delivered by the driver 146 to the one or more arrays of LEDs 144. The first power controller segment 148 may be configured to be addressable in a wired and/or wireless network, such as a wireless channel shown at 150 (or a wired channel such as may be provided via Date Recue/Date Received 2023-09-05 the cable segment 132), to receive commands to set the first power level by way of sensor segment 152. In this case, the sensor segment 152 may be integrally provided by the first power controller segment 148. As can be seen in figure 12, the non-track lighting module 122 may include a passage 122a to receive the first wireless sensor segment 152. The first power controller segment may be configured to communicate with the first wireless sensor segment to exchange signals on the wireless network.

[00187] Referring to figure 14, the second power supply segment 142 may further comprise a second power supply 154 and a second power controller segment 156 for controlling a second power level of output power to be delivered by the second power supply 154 to the one or more lighting submodules 136.

As can be seen in figure 12, the track lighting module may include a passage 120a to receive the sensor segment 158.

[00188] Thus, in some example embodiments as shown in figure 11, a designated first number of one or more of the first plurality of grid segments 102 may be configured to provide at least one lighting zone 160, wherein the at least one lighting zone 160 may include at least one direct lighting zone 162 and/or an oppositely oriented indirect lighting zone 164.

[00194] As can be seen in figure 15, the track lighting module 178 may be configured to be received in the first channel 174 in a configuration to receive the one or more lighting submodules 184. Each track lighting module 178 may include a track structure 186 defining a second channel 188, and each lighting submodule 184 may include a coupling structure 190 to be received by the track structure 186 in the second channel 188 in an operative position wherein the track structure 186 and the coupling structure 190 are configured to deliver the low voltage power to the lighting submodule 184.

In the example embodiment of figure 16, the mounting structure 196 may include a pair of arms

198 configured to extend along opposite boundaries 170a of the housing structure segment 170, and the retaining structure 200 may be configured to releasably engage at least one of the arms 198 and the housing structure segment 170. The retaining structure may include a retaining plate 200a removably secured to the arms 198 by way of fasteners 200b extending into correspondingly aligned passages in the retaining plate 200a and the arms 198. The bridging structure may also be associated with an anchoring structure 201 providing a cable 210a to anchor and/or support at least one pendant or non-pendant light fixture 193 supporting the at least one array 193.
[00198] Referring to figure 19, the non-track lighting module 202 may be configured to be received in the first channel 174 in a configuration to anchor at least one pendant or non-pendant light fixture thereto, shown schematically at 203 containing at least one of the one or more arrays 192.

[00199] The non-track lighting module 202 may include a coupling structure 204 to be received in the first channel 174 and configured to receive the line voltage power from the mounting sector 176 and to deliver the low voltage power to the at least one pendant or non-pendant light fixture 203 thereto, containing the at least one array 192. A bridging structure 204 such as shown at 206 may enable electrical connections between the coupling structure 204 and the at least one pendant or non-pendant light fixture.

[00200] As may apply to the track lighting module 178, the non-track lighting module 202 may include one or more releasable locking structures 208 to removably lock the non-track lighting module 202 in the first channel 174. The one or more releasable locking structures 208 may include one or more latches 210 movable between a released position (shown longitudinally oriented in figure 21) and a locking position (in which they transversely oriented as shown in dashed lines), wherein in the locking position the one or more latches engage a complementary stop segment, in this case a pair of opposed stop segments 211, associated with the housing segment adjacent the first channel.

[00201] As can be seen in figure 22, the non-track lighting module 202 may be provided with a sensor segment 212 (and a cover 212a as seen in protective cover as shown in figure 21) to be addressable in a wired and/or wireless network to exchange operational messages or commands which may be associated with one or more operational or specified attributes of the non-track model 202 or other segments, structures or models in a particular portion or regions of a grid lighting network, including an identity of or designated locational datum or data for or in reference or a designated location, to one or more such non-track modules or track modules, or to receive operational commands for controlling the lower voltage power to be delivered to the one or more arrays of one or more LEDs.

[00202] Thus, as shown in the figures 2, 6 and 23, example embodiments of a grid lighting system (or network) may provide at least one housing segment which may be configured to be suspended in a first position below the ceiling structure, for example as shown in figure 2. Alternatively, the at least one housing segment which may be configured to be positioned in a second position adjacent a facing surface defined by the Date Recue/Date Received 2023-09-05 ceiling structure, for example as may be provided by the configuration of figure 6.
Alternatively, the at least one housing segment may be configured to be positioned in other configurations, such as in a third position within the ceiling structure with the at least one lighting zone accessible adjacent the facing surface, as shown by the configuration of figure 23.

[00203] Figure 23 thus shows a configuration with a housing segment 220 in the third position within a lighting zone adjacent the facing surface 224 of a grid lighting network 225 in a ceiling structure 226.

[00204] Referring to figure 24, an anchor structure (not shown) may be provided for securing the housing segment 220 in the third position. A lighting module 228 may include at least one light delivery structure 230 configured to be directed deliver light to a designated region in an interior space. In the example embodiment of figure 24, the lighting module 228 may include a pair of the light delivery structures shown at 232, 234 configured to be directed deliver light to respective designated regions in the interior space. The pair of light delivery structures 232, 234 may be configured to deliver light at opposed angles relative to a vertical axis Y, and wherein the opposed angles may be substantially equal or be unequal relative to the vertical axis Y.

[00205] As can further be seen in the example embodiment of figure 25, the housing segment 220 may include a pair of opposed first locating flanges, one shown at 238, for locating adjacent corresponding boundaries of a designated opening in the facing surface 224 to receive the housing segment 220. The at least one lighting module 228 may include a pair of opposed second locating flanges, one shown at 240, each of which is configured to be located adjacent a corresponding first locating flange 238 when in an operative position in the at least one lighting zone. In this instance, the housing segment 220 and the second location flanges 240 may be provided with complementary locating structures, in the form of a projections 243a and complementary recesses 243b in either the housing segment 220 or lighting module 228.
Date Recue/Date Received 2023-09-05

[00206] Further example embodiments are shown in figures 26 and 27, in which the housing segment 220 is provided with locating flanges 242 which may be configured to engage adjacent surfaces on opposed t-bar structures 244, 246, with the housing segment 220 located therebetween. In this case, the example embodiment of figure 26 includes a track structure insert 247 for location inside the housing segment 220 to receive an LED
array module insert (not shown), while the example embodiment of figure 27 includes an LED insert module 248.

[00207] Further example embodiments are shown in figures 28 to 30. As shown in figure 28, the housing segment 220 may be located within the ceiling structure without the provision of locating flanges, by utilizing an anchor shown at 249. As shown in figures 29 and 30, combinations of an anchoring structure 249 and locating flanges 250 may be used to position the housing structure 220 in the third position, in instances where a lighting module 228 may engage with other structures within the housing segment 220 to be positioned adjacent the facing surface 224.

[00208] Figures 31 and 32 show successive views of an example embodiment in which a lighting module 254 may be provided with a light delivery structure 258 oriented at an angle oo relative to axis Y. Figures 33 and 34 show successive views of an example embodiment in which a lighting module 254 may be provided with a light delivery structure 258 oriented generally in line with axis Y.

[00209] Figures 35 to 39 illustrate another example embodiment, in this case of a modular lighting segment structure 270 for use in assembling in a series of at least two thereof for a grid lighting network, such as the recessed grid lighting network 225 of figure 23. For example, in figure 35, the modular lighting segment structure 270 is shown to be assembled, in this instance, in a series of two with an adjacent modular lighting segment structure, a portion of which is shown at 272.

The driver structure 300 may take the form of any one of the driver structures provided or configured as described herein, such as a constant current driver 76 or constant voltage driver 78 shown above in figure 5, and may thus be configured to deliver low voltage power to one or more of the first transfer channels 290, that are designated accordingly. For example, the first modular sub-junction structure 292 may receive line voltage power from the first modular junction structure 280, thus providing a supply structure such as a line power supply to the driver structure 300, by way of input line voltage power lines shown at 300a, which is shown to be coupled with an output structure 292a (figure 37) on first modular sub-junction structure 292.

[00218] In the example embodiment of figure 36, the driver structure 300 may include a pair of output power lines 300b which may be in power transfer relation with the first modular sub-junction structure 294, to deliver low voltage power to LED array 322 via a third modular sub-junction structure 314 and conductive path 324. The driver structure 300 may also include a pair of signal lines 300c which may be in signal transfer relationship with the second modular sub-junction structure 310 to receive signals appearing, in this example, on two of the first and/or second transfer channels 290, 306, via the supply line 288. Thus, in this case, the second modular sub-junction structure 294 may be in power transfer relation with the third modular sub-junction structure 314, as will be described, to deliver the low voltage power to the LED array 322 via conductive path 324, as well as by way of one or more first and/or second transfer channels designated to carry low-voltage power from the driver structure 300 to one or more LED
Date Recue/Date Received 2023-09-05 arrays associated with one or both of the modular lighting segment structures 270, 272, or others as may be provided in association therewith.

[00219] Thus, the first modular lighting structure 296 and/or second modular lighting structure 312 may include at least one first and/or second driver structure, such as for example the driver structure 300, wherein each may include a housing structure such as for example housing structure 302, to be associated, for example, with a corresponding transfer structure, wherein the first and/or second driver structures may be in power transferring relation respectively with one or more of the first and/or second sub-junction structures, for example those shown at 292, 294 and 308, 310 respectively, or one or more adjacent modular lighting segment structures.

[00220] The modular lighting segment structures 270, 272 may provide a number of options for configuring a corresponding lighting module to be installed in a grid lighting system or network, by enabling the assembler to configure each individual modular lighting structure as required. In the example of modular lighting segment structure 270, selected ones of first and second transfer channels 290, 306 may be in communication with each of the first modular junction structures 280, 282, so as to supply a common line voltage power level, a common neutral and/or signals directly or indirectly, for example either by the supply line 288, in the exemplified instance to be supplied to modular lighting segment structure 270, or by way of the jumper structure 286 to be supplied to the modular lighting segment structure 272.

[00221] Referring to figures 38 and 39, each of the modular lighting segment structures 270 and 272 may be associated with housing structures 316, 320 respectively, to support one or more LED arrays such as shown schematically at 322 in figure 39, to receive low voltage power from the driver structure 300, for example by way of one or more conductive paths, for example, or, as may be provided by cabling, wires or the like, as shown schematically at 324, as part of two or more lighting structures to be installed in a grid lighting network (such as shown at 225 in figure 23). The driver 300 shown in figures 38 and 39 in cross section for easy of illustration even though it contains specific components, elements, and structures which may be contained in a potted assembly to Date Recue/Date Received 2023-09-05 provide the driver function. In some example embodiments, the modular lighting segment structures 270, 272 may be joined to (or associated with) one another end to end, or in other configurations as desired, to form a modular assembly of a lighting structure to be located in a designated location in a grid lighting network or structure and configured to receive line power and/or other signals, directly or indirectly from at least one single line voltage supply line.

[00222] In some example embodiments, as shown in figure 36, the one or more third sub-junction structures 314 may thus be provided, to be in transferring relation with any of the elements listed above for the first and/or second sub-junction structures. The third modular sub-junction structure 314 may thus be configured for transferring relation with one or more LED arrays, such as the LED array 322 in figure 39, by configuring the third modular sub-junction structure 314 to be coupled with the output power lines 300b, via one or more of the first or second transfer channels 290, 306 in connection with the second modular junction structure 294, to deliver low voltage power to the LED
array 322.

[00223] In some example embodiments, the first, second or third modular sub-junction structures may be configured to be in transferring relation with one or more transfer channels which may not necessarily be provided on a corresponding transfer structure. In some example embodiments, the transfer structure maybe configured to be in transfer relation with a common ground with a lighting structure or accessory, or in low voltage power transfer relation with a corresponding driver structure, in which the common ground or low voltage power supply may extend to a transfer channel not associated with or a member of either the first or second groups. In some example embodiments, more than two groups of transfer channels may be provided where each group may have more than two transfer channels as illustrated, for example purposes only, in figure 35.

[00224] Figure 40 illustrates three different example configurations, among other possible configurations, deploying example embodiments of the modular lighting segment structure (MLSS). In the configuration shown in configuration 40A), MLSSs 270 and 272 are in series with two additional MLSSs 330 and 332 which may be Date Recue/Date Received 2023-09-05 structurally and/or operationally equivalent thereto, or may have other operational features not found in, or deployed by MLSSs 270 and 272. In this case, each of the subject MLSSs may be configured to establish an equivalent circuit 1, in which power may be delivered from the line voltage power supply (or supply line) 288, and progressively through the first transfer channels, in this case as power transfer channels, not shown, and jumper structures 286 from one MLSS to another.

[00225] The line power supply 288 may, in this instance, be a 9 line supply, providing a number of power lines and signal lines, including for instance those identified as Line 1, Neutral 1, Dim +1, Dim -1, Line 2, Neutral 2, Dim +2, Dim -2, and Ground. In some example embodiments, each of the jumper structures 286 may be provided with modular junction structures on opposed end regions thereof, to establish line voltage power, low voltage and/or signal transfer relation, or a sub-combination thereof, with the corresponding modular junction structures 282 on MLSS 270 and modular junction structure 280 on MLSS 272. Alternatively, one or both end regions of the jumper structure may be integrally formed or otherwise connected to one or both of and MLSS 272. Alternatively, the line voltage power supply 288 may provide other configurations in which the power supply and signal lines may involve a greater or lesser number of such supply lines. For example, the line power supply line may be configured to deliver signals without separate signal lines, by using the characteristics of the power being received on the power lines as a carrier wave for the signal. In still further configurations, signals may be delivered using other routes, such as by way of wireless signals, for example as discussed in other example embodiments herein, for example by providing wireless receiver shown schematically at 289 in figure 37, which may be configured to be signal transfer relation with one or more of the first and second transfer channels, as shown in one example, where the wireless receiver may be operatively coupled with second modular sub-junction structure 308, as an alternative to the second modular lighting fixture 312.

[00226] Meanwhile, each MLSS may be provided with a driver structure 300, enabling driver structure output power to be delivered to one or more LED arrays (not shown) associated with each respective MLSS. In this case, each of the subject MLSSs may be Date Recue/Date Received 2023-09-05 also configured to transfer signals, so that such signals may be delivered from the supply line 288, and progressively through the first transfer channels, and jumper structures 286 from one MLSS to another.

[00227] While the MLSS 270, 272 are shown to be in series, in some cases they may be configured to be in parallel. Further, the sub-junction structure delivering line power to the driver structures may be configured to be in parallel with the first and/or second power transfer channels.

Solid or dashed double or single arrow lines are provided to represent conductive paths, and in some cases are shown to cross one another, for illustration purposes only and not intended to indicate that any such crossing conductive paths in a common transferring relationship, unless indicated to the contrary. Furthermore, the solid or dashed arrow lines are intended to show a limited number of conductive path connections, including power lines and the like, and not intended to show all possible combinations of such conductive path connections.

Where one or more transfer relationships are not shown or described herein with respect to elements or structures shown in figures 40 to 45, it is to be understood that any such element or structure may be so configured.

[00229] In the example of Figure 41, with reference to figure 40A to C, circuit 1 or circuit 2 may include first power transfer channels 290a first signal transfer channels 290b, first low voltage power transfer channels 290c, and/or second line voltage power transfer channels 306a, second signal transfer channels 306b and second low voltage transfer channels 306c.

[00235] Figure 42 provides a schematic representation of a number of example configurations, including configuration 40A and Figure 36, of MLSS 270 and/or MLSS
272. In this case, the first modular sub-junction structure 292 may be in power transfer relation with the first modular junction structure 280 indirectly via first line voltage transfer channels 306a, and the driver structure 300 via input power line 300a. The first Date Recue/Date Received 2023-09-05 modular sub-junction structure 294 may be in low voltage power transfer relation with the driver structure 300 and the LED array 322, via second low voltage power transfer channels 306c, third modular junction structure 314 and conductive path 324.
Meanwhile, the second modular sub-junction structure 310 may be in signal transfer relation with the first signal transfer channels 290b and/or the driver structure 300 via signal lines 300c, and/or available for a power or signal transfer relationship with another element or structure as described herein.

[00236] Figure 40B shows a variant, in which a series of six MLSSs configured with line power being delivered throughout. In this configuration, the MLSSs 270, 272 may be configured differently to form two different circuit configurations, for example to yield two different operating conditions arising from the two different circuit, driver or signal configurations such as settings and the like. This may be achieved, for example, by deploying the driver structure 300 in the first circuit by way of the first power transfer channels 290 (not shown), whereas a second circuit configuration may deploy a different driver structure configuration, or another lighting accessory via the second power transfer channels 306 (not shown).

[00237] In the configuration shown in figure 40C), two line voltage power sources 288 may be provided to deliver line power to each of two groups of MLSSs, including MLSS
270 where it assumes a host or server role by providing driver structure output power via the power transfer structure 274, such as by way of first and/or second power transfer channels 290, 306 to a respective power transfer structure 334 in each of one or more client MLSSs 336, via jumper structures 286 along the series of client MLSSs 336. In this instance, each of client MLSSs 336 may not be provided with a driver structure 300, though they may be provided with other configurations to provide additional capabilities to deliver functions to structures associated with each respective client MLSS.

[00238] Figure 43 provides a schematic representation of an example configuration 40C, of MLSS 336, to transfer line voltage power and/or signals from MLSS 270 to at least one MLSS 336 toward an MLSS 336 which is in low voltage power transfer, or signal relation directly or indirectly with an LED array. In this case, the first modular Date Recue/Date Received 2023-09-05 sub-junction structures 292, 294, the second modular sub-junction structures 308, 310, as well as the third modular sub-junction structure 314 may not be in a power or signal transfer relation with either the first or section transfer channels 290a, 290b, 306a and 306b. Meanwhile, the first modular junction structures 280 and 282 may be in power and/or signal transfer relation with the first power and signal transfer channels 290a, 290b and the second power and signal transfer channels 306a, 306b, as well as the line power supply 288 and the jumper 286 respectively. In this configuration, the MLSS
336 may perform the role of transferring line voltage power (or low voltage power by way of low voltage power transfer channels (not shown) and signals to a downstream MLSS
336, for example as may be shown in figure 44, in which the second modular sub-junction structure 308 may be in a power or signal transfer relation with either the first line voltage power or signal transfer channels 290a, 290b, while the second sub-junction structure 310 may be in a power or signal transfer relation with line voltage power or signal transfer channels 306a and 306b, or with first modular junction structure 282, so as to deliver line voltage power and/or signals to driver structure 300.
