[0004] TECHNICAL FIELD

[0005] The present disclosure relates generally to lighting solutions, and in particular to retractable lighting devices.

[0006] BACKGROUND

[0007] Light fixtures can vary in dimension from a one or two feet to eight feet or more, for example, in length. For example, a light fixture that has a specific length may be selected for installation in a particular space based on, for example, the dimensions of the installation space. In some cases, longer and / or wider light fixtures may pose challenges related to packaging, storage, and / or installation. For example, packaging a relatively long light fixture may be more challenging than packaging a relatively shorter light fixture. As another example, carrying or lifting a relatively long light fixture, for example, during transportation, storage, and / or installation, may pose challenges as compared to relatively shorter light fixtures. Thus, a solution that enables shortening the length of a light fixture until the light fixture needs to have a full length may be desirable.

[0008] SUMMARY

[0039] In some example embodiments, the housing segment 114 may include sliding slots 128, 134 that are on opposite sides of the retractable lighting device 100 from each other. For example, the side frame 124 of the housing segment 114 may include the sliding slot 128, and the side frame 126 of the housing segment 114 may include the sliding slot 134. The sliding slot 128 may extend close to the entire length of the side frame 124, and the sliding slot 134 may extend close to the entire length of the side frame 126. The sliding slot 128 may include an end slot 130 at an end portion of the sliding slot 128. The sliding slot 134 may include an end slot 136 at an end portion of the sliding slot 134.

[0040] In some example embodiments, the retractable lighting device 100 may include a flexible lens 110 that is attached to the lighting device segments 102, 104. For example, the flexible lens 110 may be foldable such that a portion of the flexible lens 110 is overlaid or otherwise positioned on the lighting device segment 104 when the retractable lighting device 100 is in the retracted position shown in FIGS. 1A-1C. Another portion of the flexible lens 110 may be attached to the housing segment 112 at a bottom side of the lighting device segment 102 in the orientation of the retractable lighting device 100 shown in FIGS. 1A-1C.

[0041] In some example embodiments, the retractable lighting device 100 may include an electronics housing 120 that is sized to contain an electrical component (e.g., a driver or another power supply component illustratively shown as component 148 in FIG. 1C). The electronics housing 120 may be attached to the housing segment 112 at a back side of the housing segment 112. For example, the electronics housing 120 may be attached to the 2024PF80052

[0042] 5 back cover 116 of the housing segment 112. To illustrate, the lighting device segment 104 may be smaller in size than the lighting device segment 102, and the lighting device segment 104 and the electronics housing 120 may both be at the back side of the housing segment 112 when the retractable lighting device 100 is in the retracted position shown in FIGS. 1A-1C. For example, the lighting device segment 104 may have a length that is about forty percent of the total length of the retractable lighting device 100, and the lighting device segment 102 may have a length that is about sixty percent of the total length of the retractable lighting device 100. In some alternative embodiments, the electronics housing 120 may be at a different location without departing from the scope of this disclosure.

[0043] In some example embodiments, the lighting device segment 104 includes edge-lit panel attachment structures 142, 144. The edge-lit panel attachment structure 142 may be integrated with or otherwise attached to the side frame 124 of the housing segment 114. The edge-lit panel attachment structure 144 may be integrated with or otherwise attached to the side frame 126 of the housing segment 114. The side frame 124 and the side frame 126 may be on opposite sides of the housing segment 114 as shown in FIGS. 1 A-1C. The edge-lit panel attachment structures 142, 144 may be used to retain an edge-lit panel 140 of the lighting device segment 104. In general, the lighting device segment 102 may include a corresponding edge-lit panel that is supported by edge-lit panel attachment structures corresponding to the edge-lit panel attachment structures 142, 144 as can be readily understood by those of ordinary skill in the art with the benefit of this disclosure.

[0044] FIG. 2 illustrates a closeup view for a comer of the retractable lighting device 100 of FIGS. 1A-1C according to an example embodiment. Referring to FIGS. 1A-2, in some example embodiments, the lighting device segment 104 includes a light source 202 (e.g., a light emitting diode (LED) light source). For example, the light source 202 may be attached to the edge-lit panel attachment structure 142 or another structure that may be attached to or integrally formed with the side frame 124 of the housing segment 114 of the lighting device segment 104. The light source 202 may be positioned to emit a light into the edge-lit panel 140 that can emit the light through a broad surface of the edge-lit panel 140, for example, toward the area below the retractable lighting device 100 as can be readily understood by those of ordinary skill in the art with the benefit of this disclosure. The lighting device segment 104 may include another light source that is positioned on the side of the side frame 126 to emit a light into the edge-lit panel. In some alternative embodiments, the light source 202 may be at another location than shown without departing from the scope of this disclosure. 2024PF80052

[0046] In some example embodiments, the lighting device segment 104 is smaller in size than the lighting device segment 102 where a back cover 116 of the housing segment 112 of the lighting device segment 102 extends beyond an open end 204 of the lighting device segment 104. As described above, the housing segment 112 may include the side frame 122 and the end frame 146. The end frame 146 may be on an opposite side of the lighting device segment 102 from an open end of the lighting device segment 102 that gets abutted against the open end 204 of the lighting device segment 104 when the retractable lighting device 100 is in a fully extended position. A portion of the flexible lens 110 may be positioned on the back cover 118 of the housing segment 114 of the lighting device segment 104. As described above, the side frame 124 of the housing segment 114 may include the sliding slot 128 that is terminated at an end slot 130. For example, the end slot 130 may be shaped and sized to enable more movements of a fastener that may extend therethrough as compared to other portions of the sliding slot 128. In some alternative embodiments, the end slot 130 may be omitted without departing from the scope of this disclosure.

[0047] In some alternative embodiments, the electronics housing 120 may be omitted and at another location of the retractable lighting device 100, and the lighting device segments 102, 104 may be equal in size. In some alternative embodiments, the retractable lighting device 100 may have a different shape than shown without departing from the scope of this disclosure. In some alternative embodiments, the lighting device segment 102, 104 may be equal or substantially equal in size without departing from the scope of this disclosure. In some alternative embodiments, the edge-lit panel 140 may be attached to the housing segment 114 in a different manner than shown without departing from the scope of this disclosure. In some alternative embodiments, the edge-lit panel 140 may be omitted without departing from the scope of this disclosure. For example, the retractable lighting device 100 may be another type of lighting device instead of an edge-lit light fixture. In some alternative embodiments, some components of the retractable lighting device 100 may have a different shape than shown without departing from the scope of this disclosure. In some alternative embodiments, the flexible lens 110 may be omitted without departing from the scope of this disclosure.

[0048] FIGS. 3A-3C illustrate different views of portions of the retractable lighting device 100 of FIGS. 1A-1C from a side according to an example embodiment, and FIGS. 4A- 4C illustrate different views of portions of the retractable lighting device 100 of FIGS. 1A-1C from another side according to an example embodiment. Referring to FIGS. 1 A-4C, in some example embodiments, the lighting device segment 104 is overlaid on the lighting device 2024PF80052

[0049] 7 segment 102 when the retractable lighting device 100 is in the retractable position. The lighting device segment 102 may include the housing segment 112 that may include the side frames 122, 132, the top cover 116, and the end frame 146. The electronics housing 120 may be attached to the top cover 116. The top cover 116 may be integrally formed with the side frames 122, 132 and / or the end frame 146 or may be attached thereto by fasteners. In general, the housing segment 112 may be made from plastic and / or a metal such as aluminum using one or more of the methods such as molding, casting, cutting, bending, stamping, welding, etc.

[0050] In some example embodiments, the lighting device segment 104 may include the housing segment 114 that may include the side frames 124, 126, the top cover 118, and the end frame 138. The top cover 118 may be integrally formed with the side frames 124, 126 and / or the end frame 138 or may be attached thereto by fasteners. In general, the housing segment 114 may be made from plastic and / or a metal such as aluminum using one or more of the methods such as molding, casting, cutting, bending, stamping, welding, etc.

[0051] In some example embodiments, the retractable lighting device 100 may include, on one side, the attachment system 106 that is attached to the housing segment 112 and the housing segment 114 such that the lighting device segment 104 is slidable relative to the lighting device segment 102 while the housing segment 112 and the housing segment 114 remain attached to each other. To illustrate, the side frame 122 of the housing segment 112 of the lighting device segment 102 may include a fastener hole 304 (more clearly shown in FIG. 3C) for rotatable attachment of a bracket 302 of the attachment system 106 to the housing segment 112 by a fastener. The side frame 132 of the housing segment 112 of the lighting device segment 102 may include a fastener hole 404 (more clearly shown in FIG. 4C) for rotatable attachment of a bracket 402 of the attachment system 108 to the housing segment 112 by a fastener. In FIGS. 3C, 4B, and 4C, the attachment system 106 is omitted for clarity of illustration. In FIG. 4C, the attachment system 108 is omitted for clarity of illustration.

[0052] In some example embodiments, the housing segment 114 may include, on the same side of the retractable lighting device 100 as the side frame 122 of the housing segment 112, the sliding slot 128 that is terminated at the end slot 130. The bracket 302 of the attachment system 106 that is attached to the side frame 122 may be attached to the housing segment 114 by a fastener that extends through the bracket 302 and the sliding slot 128. The housing segment 114 may include, on the same side of the retractable lighting device 100 as the side frame 132 of the housing segment 112, the sliding slot 134 that is terminated at the 2024PF80052

[0053] 8 end slot 136. When the retractable lighting device 100 is in a fully retracted position as shown in FIGS. 1 A-1C, the fastener that extends through the bracket 302 and the sliding slot 128 may be on an opposite end of the sliding slot 128 from the end slot 130 of the sliding slot 128, and the fastener that extends through the bracket 402 and the sliding slot 134 may be on an opposite end of the sliding slot 134 from the end slot 136 of the sliding slot 134.

[0054] In some example embodiments, the flexible lens 110 may be foldable such that, when the retractable lighting device 100 is in the retracted position, a portion of the flexible lens 110 is overlaid on the back cover 118 of the housing segment 114 and another portion the flexible lens 110 at a bottom side of the housing segment 112. For example, the flexible lens 110 may be curved around from the bottom side of the housing segment 112 to over the back cover 118 of the housing segment 114. For example, the flexible lens 110 may be a flexible polycarbonate lens or another type of flexible lens. In some alternative embodiments, the flexible lens 110 may be omitted without departing from the scope of this disclosure.

[0055] FIGS. 5A and 5B illustrate closeup views for the attachment system 106 of the retractable lighting device 100 of FIGS. 1A-1C according to an example embodiment. In some example embodiments, the attachment system 106 includes the bracket 302, fasteners 504, 506, and a nut 510 that gets attached to the fastener 506. The attachment system 106 may also include other components such as a gasket 508 and a washer 512. The bracket 302 may include a fastener slot 514 and a fastener hole 528. The bracket 302 may be attached to the side frame 122 of the housing segment 112 by the fastener 504 (e.g., a screw) that extends through the fastener hole 528 of the bracket 302 and the fastener hole 304 of the side frame 122. For example, the gasket 508 (e.g., a rubber gasket) may be inserted in the fastener hole 528 of the bracket 302, and the fastener 504 may be extended through the hole of the gasket into the fastener hole 304 of the side frame 122. For example, the gasket 508 may facilitate the rotation of the bracket 302 relative to the fastener 504 and / or the side frame 122 of the housing segment 112. The bracket 302 may be made from plastic and / or a metal using one or more of the methods such as molding, casting, cutting, bending, stamping, welding, etc.

[0056] In some example embodiments, the fastener 506 may extend through the sliding slot 128 of the side frame 124 of the housing segment 114 and through the fastener slot 514 of the bracket 302. For example, a threaded portion 524 of the fastener 506 may extend through the fastener slot 514 of the bracket 302 and may be held by the nut 510 on the opposite side of the bracket 302 from fastener head 526 that may be on the opposite side of the side frame 124 from the bracket 302. The washer 512 may be positioned around the 2024PF80052

[0057] 9 threaded portion 524 between the nut 510 and the bracket 302. The housing segment 114 may be slidable relative to the fastener 506 that extends through the sliding slot 128 of the side frame 124 of the housing segment 114. Because the bracket 302 is rotatably but fixedly attached to the side frame 122 of the housing segment 112, the housing segment 114 and thus the lighting device segment 104 are slidable relative to the housing segment 112 and the lighting device segment 102. Because the bracket 302 is rotatably attached to the side frame 122 of the housing segment 112 and because the lighting device segment 104 is slidable relative to the lighting device segment 102, the housing segment 114 and thus the lighting device segment 104 are movable from a position of being overlaid on the lighting device segment 104 to a position of being linearly aligned with the lighting device segment 102.

[0058] FIGS. 6A and 6B illustrate closeup views for another attachment system 108 of the retractable lighting device 100 of FIGS. 1A-1C according to an example embodiment. In some example embodiments, the attachment system 108 includes the bracket 402, fasteners 604, 606, and a nut 610 that gets attached to the fastener 606. The attachment system 108 may also include other components such as a gasket 608 and a washer 612. The bracket 402 may include a fastener slot 614 and a fastener hole 618. The bracket 402 may be attached to the side frame 132 of the housing segment 112 by the fastener 604 (e.g., a screw) that extends through the fastener hole 618 of the bracket 402 and the fastener hole 404 of the side frame 132. For example, the gasket 608 (e.g., a rubber gasket) may be inserted in the fastener hole 618 of the bracket 402, and the fastener 604 may be extended through the hole of the gasket into the fastener hole 404 of the side frame 132. For example, the gasket 608 may facilitate the rotation of the bracket 402 relative to the fastener 604 and / or the side frame 132 of the housing segment 112. The bracket 402 may be made from plastic and / or a metal using one or more of the methods such as molding, casting, cutting, bending, stamping, welding, etc.

[0059] In some example embodiments, the fastener 606 may extend through the sliding slot 134 of the side frame 126 of the housing segment 114 and through the fastener slot 614 of the bracket 402. For example, a threaded portion 620 of the fastener 606 may extend through the fastener slot 614 of the bracket 402 and may be held by the nut 610 that is on the opposite side of the bracket 402 from the fastener head 616. The fastener head 616 may be on the opposite side of the side frame 126 from the bracket 402. The washer 612 may be positioned around the threaded portion 620 between the nut 610 and the bracket 402. The housing segment 114 may be slidable relative to the fastener 606 that extends through the sliding slot 134 of the side frame 126 of the housing segment 114. Because the bracket 2024PF80052

[0060] 10

[0061] 402 is rotatably but fixedly attached to the side frame 132 of the housing segment 112, the housing segment 114 and thus the lighting device segment 104 are slidable relative to the housing segment 112 and the lighting device segment 102. Because the bracket 402 is rotatably attached to the side frame 132 of the housing segment 112 and because the lighting device segment 104 is slidable relative to the lighting device segment 102, the housing segment 114 and thus the lighting device segment 104 are movable from a position of being overlaid on the lighting device segment 104 to a position of being linearly aligned with the lighting device segment 102.

[0062] Referring to FIGS. 1A-6B, in some example embodiments, the lighting device segment 102 includes light sources 518, 622 (e.g., LED light sources) and an edge-lit panel 516. The edge-lit panel 516 may be retained by an edge-lit panel attachment structure 520 (more clearly shown in FIG. 5A) or another structure that may be attached to or integrally formed with the side frame 122 of the housing segment 112 of the lighting device segment 102 and by an edge-lit panel attachment structure 624 or another structure that may be attached to or integrally formed with the side frame 132 of the housing segment 112 of the lighting device segment 102. The light sources 518, 622 may be positioned to emit a respective light into the edge-lit panel 140 that can emit the combined light through a broad surface of the edge-lit panel 140, for example, toward the area below the retractable lighting device 100 as can be readily understood by those of ordinary skill in the art with the benefit of this disclosure.

[0063] In some example embodiments, when the retractable lighting device 100 is in a fully extended position, an open end 530 of the lighting device segment 102 may be abutted against the open end 204 of the lighting device segment 104, and the end frame 146 of the lighting device segment 102 and the end frame 138 of the lighting device segment 104 may be on opposite ends of the retractable lighting device 100.

[0064] In some alternative embodiments, the brackets 302, 402 may have a different shape than shown without departing from the scope of this disclosure. In some alternative embodiments, the edge-lit panel 516 may be omitted without departing from the scope of this disclosure. For example, the retractable lighting device 100 may be a type of lighting device other than an edge-lit light fixture. In some alternative embodiments, one of the light sources 518, 622 may be omitted without departing from the scope of this disclosure. In some alternative embodiments, the sliding slots 128, 134 may have a different shape or may be at different locations than shown without departing from the scope of this disclosure. In some alternative embodiments, the attachment systems 106, 108 may include other components in 2024PF80052

[0065] 11 addition to or instead of the components shown in FIGS. 5A-6B. In some alternative embodiments, the brackets 302, 402 may be attached to the housing segment 112 at different locations than shown without departing from the scope of this disclosure. In some alternative embodiments, the fasteners of the attachment systems 106, 108 may be other types of fasteners than shown without departing from the scope of this disclosure.

[0066] FIG. 7 illustrates the retractable lighting device 100 of FIGS. 1A-1C in a retracted position according to an example embodiment. For example, starting from the retractable lighting device 100 as shown in FIGS. 1A-1C, in FIG. 7, the flexible lens 110 has been removed from the back cover 118 of the housing segment 114 of the lighting device segment 104 and fully extended out. For example, FIG. 7 may show the retractable lighting device 100 during the process of extending out the retractable lighting device 100. Alternatively, FIG. 7 may show the retractable lighting device 100 during the process of retracting the retractable lighting device 100 to the position shown in FIGS. 1A-1C. In FIG. 7, the attachment systems 106, 108 may be in the positions shown in FIGS. 1-1C. In some alternative embodiments, the flexible lens 110 may be omitted without departing from the scope of this disclosure.

[0067] In some example embodiments, the lighting device segment 104 may include an electrical connector 702 that can be connected to a corresponding electrical connector or wires that may be electrically connected to an electronics component (e.g., a driver) that may be inside the electronics housing.

[0068] FIGS. 8 A and 8B illustrate different views of the retractable lighting device 100 of FIGS. 1A-1C in a partially extended position according to an example embodiment. For example, after the flexible lens 110 has be extended out as shown in FIG. 7, the lighting device segment 104 may be slid relative to the lighting device segment 102, for example, by pulling the lighting device segment 104 relative to the lighting device segment 102 while the lighting device segments 102, 104 remain attached to each other by the attachment systems 106, 108. For example, in FIG. 8A, the attachment system 106 is at a different location relative to the sliding slot 128 of the side frame 124 of the housing segment 114 of the lighting device segment 104 as compared to the location of the attachment system 106 shown in FIG. 7. To illustrate, in FIGS. 8A and 8B, the fastener 506 of the attachment system 106 is at a different location in the sliding slot 128 as compared to the location of the fastener 506 in FIG. 7. In FIGS. 8A and 8B, the bracket 302 of the attachment system 106 remains rotatably attached by the fastener 504 to the side frame 122 of the housing segment 112 of the lighting device segment 102. In FIG. 8 A, the attachment system 108 is also at a different location as 2024PF80052

[0069] 12 compared to the location of the attachment system 108 shown in FIG. 7. In FIGS. 8 A and 8B, the flexible lens 110 is omitted for clarity of illustration. Alternatively, the flexible lens 110 may be completely removed from the lighting device segment 102 or may be omitted without departing from the scope of this disclosure.

[0070] FIGS. 9 A and 9B illustrate different views of the retractable lighting device 100 of FIGS. 1A-1C in another partially extended position according to an example embodiment. In FIGS. 9A and 9B, the retractable lighting device 100 is mostly extended out where the lighting device segment 104 is still vertically (in the orientation shown in FIG. 9B) offset from the lighting device segment 102. For example, in FIG. 9A, the lighting device segment 104 has been slid relative to the lighting device segment 102 such that the attachment systems 106 and 108 are at the end slot 130 (more clearly shown in FIG. 1A) of the sliding slot 128 of the housing segment 114 and at the end slot 136 (more clearly shown in FIG. IB) of the sliding slot 134 (shown in FIG. IB) of the housing segment 114, respectively. To illustrate with respect to the attachment system 106, in FIGS. 9A and 9B, the fastener 506 may be in the end slot 130 (more clearly shown in FIG. 1A) of the housing segment 114 of the lighting device segment 104, and the bracket 302 remains rotatably attached to the side frame 122 of the housing segment 112 of the lighting device segment 102 by the fastener 504. Referring to FIGS. 6A, 6B, 9A, and 9B, the fastener 606 of the attachment system 108 may be in the end slot 136 (shown in FIG. 1A) of the housing segment 114 of the lighting device segment 104, and the bracket 402 of the attachment system 108 remains rotatably attached by the fastener 604 to the side frame 132 of the housing segment 112 of the lighting device segment 102. In FIGS. 9A and 9B, the flexible lens 110 is omitted for clarity of illustration. Alternatively, the flexible lens 110 may be completely removed from the lighting device segment 102 or may be omitted without departing from the scope of this disclosure.

[0071] FIGS. 10A and 10B illustrate different views of the retractable lighting device 100 of FIGS. 1A-1C in a fully extended position according to an example embodiment. When the retractable lighting device 100 is in the fully extended position, the lighting device segments 102, 104 are linearly aligned with each other where the lighting device segment 104 is no longer overlaid on the lighting device segment 102. The attachment systems 106, 108 remain attached to the housing segment 112 of the lighting device segment 102 and to the housing segment 114 of the lighting device segment 114.

[0072] As shown in FIGS. 10A and 10B, the bracket 302 of the attachment system 106 remains rotatably attached by the fastener 504 to the side frame 122 of the housing 2024PF80052

[0073] 13 segment 112 of the lighting device segment 102 but has been rotated from the position shown, for example, in FIGS. 8B and 9B. The bracket 302 remains attached to the housing segment 114 by the fastener 506 extending through the sliding slot 128 of the housing segment 114 and through the bracket slot 514 of the bracket 302. For example, in contrast to the location of the fastener 506 shown in FIGS. 8B and 9B, in FIGS. 10A and 10B, the fastener 506 may be at a different location in the bracket slot 514 of the bracket 302. Referring to FIGS. 6A and 6B and FIGS. 10A and 10B, the bracket 402 of the attachment system 108 remains rotatably attached by the fastener 604 to the side frame 132 of the housing segment 112 of the lighting device segment 102 but has been rotated to a similar position as the bracket 302. When the retractable lighting device 100 is in the fully extended position, the bracket 402 remains attached to the housing segment 114 by the fastener 606 extending through the sliding slot 134 of the housing segment 114 and through the bracket slot 614 of the bracket 402.

[0074] As shown in FIG. 10 A, the end frame 146 of the housing segment 112 and the end frame 138 of the housing segment 114 are on opposite ends of the retractable lighting device 100 when the retractable lighting device 100 is in the fully extended position. Electrical power from one or more power components (e.g., a power supply component such as a driver) in the electronics housing 120 may be provided to lighting components such as the light sources of the lighting device segments 102, 104. The electronics housing 120 that may be attached to the back cover 116 proximal to the end frame 146. Electrical power from the electrical component(s) in the electronics housing 120 may be provided to the light source 202 (shown more clearly in FIG. 2) of the lighting device segment 104 via an electrical cable 1002 (e.g., one or more electrical wires) connected to the electrical connector 702. The electrical connector 702 may be attached to the back cover 118 of the lighting device segment 104. The electrical connector 702 may be electrically connected (e.g., via one or more electrical wires that are routed under the back cover 118) to, for example, the one or more light sources of the lighting device segment 104. Electrical power from the electrical component in the electronics housing 120 may also be provided to the light sources 518, 622 of the lighting device segment 102.

[0075] In general, FIGS. 7-10B may show the retractable lighting device 100 during the process of extending out the retractable lighting device 100 to the fully extend position shown in FIG. 10A. The process of retracting the retractable lighting device 100, for example, to the position shown in FIG. 1 A may follow the reverse of the steps of shown in FIGS. 7-10B. 2024PF80052

[0076] 14

[0077] The retractability of the retractable lighting device 100 enables a much smaller packaging compared to a non-tractable light fixture that has the same size as the retractable lighting device 100 in the fully extended position. In contrast to a foldable light fixture, the retractable lighting device 100 requires less space to switch between a retracted position and an extended position or vice versa. The retractability of the retractable lighting device 100 results in requiring a much smaller storage space to store the retractable lighting device 100.

[0078] In some example embodiments, the retractable lighting device 100 may be a recessed light fixture or suspended light fixture. In some alternative embodiments, the retractable lighting device 100 may be a different type of lighting device than shown without departing from the scope of this disclosure. In some alternative embodiments, the retractable lighting device 100 may include more, fewer, or different components than shown without departing from the scope of this disclosure. For example, the light sources and / or other components may be omitted from the lighting device 1100 and subsequently added, for example, by a customer. In some alternative embodiments, the lighting device segments 102, 104 may be slidably attached to each other using means as other than or in addition to the attachment systems 106, 108 without departing from the scope of this disclosure. In some alternative embodiments, the attachment systems 106, 108 may each include more, fewer, or different components than shown without departing from the scope of this disclosure. In some alternative embodiments, the sliding slots 128, 134 of the housing segments 112, 114 may each have a shorter or longer than shown relative to the lengths of the housing segments 112, 114 without departing from the scope of this disclosure. In some alternative embodiments, the sliding slots 128, 134 may be at different locations than shown without departing from the scope of this disclosure.

[0079] FIGS. 11A and 11B illustrate different views of a retractable lighting device 1100 in a retracted position according to another example embodiment. In some example embodiments, the retractable lighting device 1100 includes lighting device segments 1102, 1104. In the retracted position shown in FIGS. 11A and 1 IB, the lighting device segment 1104 is stacked or otherwise overlaid on the lighting device segment 1102. The retractable lighting device 1100 may further include attachment systems 1110, 1112, 1152, 1154. The lighting device segments 1102, 1104 are slidably attached to each other by the attachment systems 1110, 1112, 1152, 1154. For example, the lighting device segment 1104 may be slid relative to the lighting device segment 1102 while remaining attached to the lighting device segment 1102 by the attachment systems 1110, 1112, 1152, 1154. In general, the attachment systems 1110, 1112, 1152, 1154 may each generally correspond to each attachment system of 2024PF80052

[0080] 15 the attachment systems 106, 108 of the retractable lighting device 100 of FIGS. 1A-1C with possible difference in some dimensions.

[0081] In some example embodiments, the lighting device segment 1102 includes a housing segment 1106 that includes side frames 1114, 1116 and an end cap 1128. The side frames 1114, 1116 may be on opposite longitudinal sides of the retractable lighting device 1100 from each other. The side frame 1114 may include a sliding slot 1118 that extends for a portion of the length of the side frame 1114. For example, the sliding slot 1118 may extend for most of the length of the side frame 1114. The side frame 1116 may include a sliding slot 1174 that extends for a portion of the length of the side frame 1116. For example, the sliding slot 1174 may extend for almost the entire length of the side frame 1116.

[0082] In some example embodiments, the lighting device segment 1104 includes a housing segment 1108 that includes side frames 1120, 1122, a back cover 1126, and an end cap 1130. The side frames 1120, 1122 may be on opposite longitudinal sides of the retractable lighting device 1100 from each other. The side frame 1120 may include a sliding slot 1124 that extends for a portion of the length of the side frame 1120. For example, the sliding slot 1124 may extend for almost the entire length of the side frame 1120. The side frame 1122 may include a sliding slot 1178 that extends for a portion of the length of the side frame 1122. For example, the sliding slot 1178 may extend for most of the length of the side frame 1122. The attachment system 1110 and the attachment system 1112 may be attached to the housing segment 1106 and to the housing segment 1108 on one longitudinal side of the retractable lighting device 1100 as the attachment system 1112, and the attachment system 1152 and the attachment system 1154 may be attached to the housing segment 1106 and to the housing segment 1108 on a second longitudinal side of the retractable lighting device 1100, where the first longitudinal side and the second longitudinal side are opposite longitudinal sides of the retractable lighting device 1100.

[0083] In some example embodiments, the attachment system 1110 may include a bracket 1136 that is attached to the side frame 1114 of the housing segment 1106 and to the side frame 1120 of the housing segment 1108. For example, the bracket 1136 may be attached to the side frame 1114 by a fastener 1138 that extends through a bracket slot 1142 of the bracket 1136 and through the sliding slot 1118 of the side frame 1114. The bracket 1136 may be fixedly but rotatably attached to the side frame 1120 of the housing segment 1108 by a fastener 1140 that extends through a bracket hole of the bracket 1136 and through a corresponding fastener hole of the side frame 1120. To illustrate, the fastener 1138 may slide 2024PF80052

[0084] 16 in the sliding slot 1118 of the side frame 1114 along with the bracket 1136 as the lighting device segment 1104 is slid relative to the lighting device segment 1102.

[0085] In some example embodiments, the attachment system 1112 may include a bracket 1144 that is attached to the side frame 1114 of the housing segment 1106 and to the side frame 1120 of the housing segment 1108. For example, the bracket 1144 may be attached to the side frame 1120 by a fastener 1148 that extends through a bracket slot 1150 of the bracket 1144 and through the sliding slot 1124 of the side frame 1120. The bracket 1144 may be fixedly but rotatably attached to the side frame 1114 of the housing segment 1106 by a fastener 1146 that extends through a bracket hole of the bracket 1144 and through a corresponding fastener hole of the side frame 1114. To illustrate, the lighting device segment 1104 may slide relative to the fastener 1148 as the lighting device segment 1102 is slid relative to the lighting device segment 1102. For example, the lighting device segment 1104 may be pulled while the lighting device segment 1102 is held in place to slide the lighting device segment 1104 relative to the lighting device segment 1102.

[0086] In some example embodiments, the attachment system 1152 (more clearly shown in FIG. 11 A) may include a bracket 1156 that is attached to the side frame 1116 of the housing segment 1106 and to the side frame 1122 of the housing segment 1108. For example, the bracket 1156 may be attached to the side frame 1116 by a fastener 1158 that extends through a bracket slot 1162 of the bracket 1156 and through the sliding slot 1174 of the side frame 1116. The bracket 1156 may be fixedly but rotatably attached to the side frame 1122 of the housing segment 1108 by a fastener 1160 that extends through a bracket hole of the bracket 1156 and through a corresponding fastener hole of the side frame 1122. To illustrate, the fastener 1158 may slide in the sliding slot 1174 of the side frame 1116 along with the bracket 1156 as the lighting device segment 1104 is slid relative to the lighting device segment 1102.

[0087] In some example embodiments, the attachment system 1154 (more clearly shown in FIG. 1 IB) may include a bracket 1164 that is attached to the side frame 1116 of the housing segment 1106 and to the side frame 1122 of the housing segment 1108. For example, the bracket 1164 may be fixedly but rotatably attached to the side frame 1116 of the housing segment 1106 by a fastener 1166 that extends through a bracket hole of the bracket 1164 and through a corresponding fastener hole of the side frame 1116. The bracket 1164 may be attached to the side frame 1122 by a fastener 1168 that extends through a bracket slot 1170 of the bracket 1164 and through the sliding slot 1178 of the side frame 1122. To illustrate, the lighting device segment 1104 may slide relative to the fastener 1168 as the 2024PF80052

[0088] 17 lighting device segment 1104 is slid relative to the lighting device segment 1102. For example, the lighting device segment 1104 may be pulled while the lighting device segment 1102 is held in place to slide the lighting device segment 1104 relative to the lighting device segment 1102.

[0089] In some example embodiments, the lighting device segments 1102, 1104 may each include a respective light module. For example, the lighting device segment 1102 may include a light module 1132 (e.g., an LED light module) positioned to emit a light downward in the orientation of the retractable lighting device 1100 shown in FIGS. 11 A and 1 IB. The lighting device segment 1102 may have an open end 1134 that is at an opposite end of the lighting device segment 1102 from the end cap 1128 of the housing segment 1106 of the lighting device segment 1102. The lighting device segment 1104 may include a light module (e.g., an LED light module) positioned to emit a light downward in the orientation of the retractable lighting device 1100 shown in FIGS. 11 A and 1 IB. The lighting device segment 1104 may have an open end 1172 that is at an opposite end of the lighting device segment 1104 from the end cap 1130 of the housing segment 1108 of the lighting device segment 1104. When the retractable lighting device 1100 is in a fully extended position, the end caps 1128, 1130 may be at opposite ends of the retractable lighting device 1100, and the lighting device segments 1102, 1104 may be linearly aligned with each other where the open ends 1134 and 1172 of the lighting device segments 1102 and 1104, respectively, may be abutted against each other.

[0090] FIG. 12 illustrates the retractable lighting device 1100 of FIGS. 11A and 11B in a partially extended position according to an example embodiment. In contrast to the position of the retractable lighting device 1100 shown in FIGS. 11A and 1 IB, in IFG. 12, the lighting device segment 1104 has been slid relative to the lighting device segment 1102. Because the bracket 1136 is rotatably but fixedly attached to the side frame 1120 of the housing segment 1108 of the lighting device segment 1104 by the fastener 1140 and because the bracket 1136 is attached to the side frame 1114 of the housing segment 1106 of the lighting device segment 1102 by the fastener 1138 that extends through the sliding slot 1118 of the side frame 1114, in FIG. 12, the bracket 1136 has slid / moved along with the lighting device segment 1104 relative to the lighting device segment 1102. Because the bracket 1144 is rotatably but fixedly attached to the side frame 1114 of the housing segment 1106 of the lighting device segment 1102 by the fastener 1146 and because the bracket 1144 is attached to the side frame 1120 of the housing segment 1108 of the lighting device segment 1104 by the fastener 1148 that extends through the sliding slot 1124 of the side frame 1120, in FIG. 2024PF80052

[0091] 18

[0092] 12, the lighting device segment 1104 has slid / moved relative to the bracket 1144 that remains attached to the housing segment 1106 of the lighting device segment 1102. In FIG. 1 IB, the position of the bracket 1156 (shown in FIG. 1 IB) may correspond to the position of the bracket 1136, and the position of the bracket 1164 (shown in FIG. 1 IB) may correspond to the position of the bracket 1144.

[0093] FIGS. 13 and 14 illustrate different views of the retractable lighting device 1100 of FIGS. 11 A and 1 IB in a fully extended position according to an example embodiment. In some example embodiments, when the retractable lighting device 1100 is in the fully extended position, the lighting device segments 1102, 1104 are linearly aligned with each other where the lighting device segment 1104 is no longer overlaid on the lighting device segment 1102. The attachment systems 1110, 1112, 1152, 1154 remain attached to the housing segment 1106 of the lighting device segment 1102 and to the housing segment 1108 of the lighting device segment 1104.

[0094] As shown in FIGS. 13, the bracket 1144 of the attachment system 1112 remains rotatably attached by the fastener 1146 to the side frame 1114 of the housing segment 1106 of the lighting device segment 1102 but has been rotated from the position shown, for example, in FIGS. 11 A and 12. The bracket 1144 also remains attached to the housing segment 1108 by the fastener 1148 extending through the sliding slot 1124 of the housing segment 1108 and through the bracket slot 1150 of the bracket 1144. In contrast to the position of the fastener 1148 in the sliding slot 1124 when the retractable lighting device 1100 is in the retracted position shown in FIG. 11 A, in FIG. 13, the fastener 1148 may be at or close to the opposite end of the sliding slot 1124.

[0095] When the retractable lighting device 1100 is in the fully extended position as shown in FIGS. 13, the bracket 1136 of the attachment system 1110 remains rotatably attached by the fastener 1140 to the side frame 1120 of the housing segment 1108 of the lighting device segment 1104 but has been rotated in an opposite direction from the rotational direction of the bracket 1144. The bracket 1136 also remains attached to the housing segment 1106 by the fastener 1138 that extends through the bracket slot 1142 of the bracket 1136 and the sliding slot 1118 of the side frame 1114 of the housing segment 1106. In contrast to the position of the fastener 1138 in the sliding slot 1118 when the retractable lighting device 1100 is in the retracted position shown in FIG. 11A, in FIG. 13, the fastener 1138 may be at or close to the opposite end of the sliding slot 1118.

[0096] When the retractable lighting device 1100 is in the fully extended position as shown in FIGS. 14, the bracket 1156 of the attachment system 1152 remains rotatably 2024PF80052

[0097] 19 attached by the fastener 1160 to the side frame 1122 of the housing segment 1108 of the lighting device segment 1104 but has been rotated from the position shown, for example, in FIGS. 1 IB. The bracket 1156 also remains attached to the housing segment 1106 by the fastener 1158 extending through the sliding slot 1174 of the housing segment 1106 and through the bracket slot 1162 of the bracket 1156. In contrast to the position of the fastener 1158 in the sliding slot 1174 when the retractable lighting device 1100 is in the retracted position shown in FIG. 1 IB, in FIG. 14, the fastener 1158 may be at or close to the opposite end of the sliding slot 1174.

[0098] When the retractable lighting device 1100 is in the fully extended position as shown in FIGS. 14, the bracket 1164 of the attachment system 1154 remains rotatably attached by the fastener 1166 to the side frame 1116 of the housing segment 1106 of the lighting device segment 1102 but has been rotated in an opposite direction from the rotational direction of the bracket 1156. The bracket 1164 also remains attached to the housing segment 1108 by the fastener 1168 that extends through the bracket slot 1170 of the bracket 1164 and the sliding slot 1178 of the side frame 1122 of the housing segment 1108. In contrast to the position of the fastener 1168 in the sliding slot 1178 when the retractable lighting device 1100 is in the retracted position shown in FIG. 11A, in FIG. 14, the fastener 1168 may be at or close to the opposite end of the sliding slot 1178. As shown in FIGS. 13 and 14, the end cap 1128 of the lighting device segment 1102 and the end cap 1130 of the of the lighting device segment 1104 are on opposite ends of the retractable lighting device 1100 when the retractable lighting device 1100 is in the fully extended position.

[0099] FIG. 15 illustrates a closeup view an electrical connection of the retractable lighting device 1100 shown in FIG. 13 according to an example embodiment. Referring to FIGS. 13-15, in some example embodiments, electrical power from one or more power components (e.g., a power supply component such as a driver) that may be in the housing segment 1106 (e.g., behind a top cover 1302 of the housing segment 1106) may be provided to lighting components of the lighting device segments 1102, 1104. To illustrate, electrical power from the electrical component(s) in the housing segment 1106 of the lighting device segment 1102 may be provided to the light source and / or other components of the lighting device segment 1104 via one or more electrical cables 1304 connected to an electrical connector 1306 that may be attached to the back cover 1126 of the housing segment 1108. Alternatively, the lighting device segment 1104 may include one or more power components that can provide power to the lighting components of the lighting device segment 1102 via the one or more electrical cables 1304 that are connected to the electrical connector 1306. 2024PF80052

[0100] 20

[0101] In general, the housing segments 1106, 1108 may be made from plastic and / or a metal such as aluminum using one or more of the methods such as molding, casting, cutting, bending, stamping, welding, etc. The brackets of the lighting device segments 1102, 114 may be made from plastic and / or a metal such as aluminum using one or more of the methods such as molding, casting, cutting, bending, stamping, welding, etc.

[0102] In general, FIGS. 11A-14 may show the retractable lighting device 1100 during the process of extending out the retractable lighting device 1100 to the fully extend position shown in FIG. 10A. The process of retracting the retractable lighting device 1100, for example, to the position shown in FIG. 11 A may follow the reverse of the steps of shown in FIGS. 11A-14.
