Description

Technical Field

[0001] The present disclosure relates generally to light fixtures, and more particularly to systems, methods, and apparatus for engaging light fixtures. Background Art

[0002] Linear luminaires are often mounted end-to-end to create a single, extended linear luminaire. In such cases, light may leak between adjacent luminaires. Many methods (e.g., clips, brackets with screws) are used in current technology to try to minimize or eliminate light leakage between adjacent luminaires. Some of these methods are ineffective. Others of these methods, while more effective in achieving light leakage goals, can complicate the installation process, increasing costs and frustration for the installer. Summary of the invention

Where applicable, use of the exemplary embodiments described herein satisfies (and / or allows linear luminaires to satisfy) such standards.

[0026] If a component of a drawing is described but not explicitly shown or labeled in that drawing, the label used for a corresponding component in another drawing may be inferred for that component. Conversely, if a component in a drawing is labeled but not described with respect to that drawing, the description of such a component may be substantially the same as the description of the corresponding component in another drawing. The numbering scheme for the different components in the drawings herein is that each component is a three-digit number, and the corresponding components in the other drawings have the same last two digits.

[0027] Furthermore, unless explicitly stated, a statement that a particular embodiment (e.g., as shown in the figures herein) does not have a particular feature or component does not mean that such embodiment cannot have such feature or component.

[0033] Figures 7A to 7D According to some exemplary embodiments, Figures 1A to 1I The gripping member 770 of the engagement system 195. Specifically, Fig. 7A A top view of the gripper 770 is shown. Figure 7B A side view of gripper 770 is shown. Figure 7C A bottom view of the grip 770 is shown.

[0034] Fig.7D A perspective view of gripper 770 is shown. Fig. 8A and 8B According to some exemplary embodiments, Figures 1A to 1I The pin 880 of the engagement system 195. Specifically, Fig. 8A A front view of pin 880 is shown. Figure 8B A side view of pin 880 is shown.

[0035] refer to Figures 1A to 8B, the linear lighting system 100 in this example includes two linear luminaires 190 (linear luminaire 190-1 and linear luminaire 190-2) being joined together using an exemplary joining system 195. Each linear luminaire 190 includes a frame 220 and a tray 330. In this case, linear luminaire 190-1 includes a frame 220-1 and a tray 330-1, and linear luminaire 190-2 includes a frame 220-2 and a tray 330-2. Frame 220-1 and frame 220-2 are configured to be substantially identical to each other. Similarly, tray 330-1 and tray 330-2 are configured to be substantially identical to each other.

[0036] like Figure 2A and 2B As shown, each frame 220 of the linear light fixture 190 includes a top wall 227, a left side wall 223, and a right side wall 222. The space below the top wall 227 and between the left side wall 223 and the right side wall 222 forms a cavity 254, and the tray 330 and most of the joint system 195 are arranged inside the cavity. In some cases, such as in this example, the left side wall 223 and the right side wall 222 extend upward above the top wall 227. In such a case, the top surface of the top wall 227 and the top of the left side wall 223 and the right side wall 222 form a cavity 298. In this case, the top wall 227 and the left side wall 223 and the right side wall 222 are substantially planar. Moreover, in this example, the top wall 227 is substantially perpendicular to the left side wall 223 and the right side wall 222. In alternative embodiments, the top wall 227, the left side wall 223, and / or the right side wall 222 can be non-planar (e.g., curved, made of multiple non-planar pieces). Additionally or in the alternative, the top wall 227 may form a non-perpendicular angle relative to the left side wall 223 and / or the right side wall 222 .

[0037] The top wall 227 of the frame 220 includes one or more features that can be used by the exemplary engagement system 195. For example, in this case, the bottom surface of the top wall 227 can have one or more protruding features 224 that can be used to receive and guide the frame receiving features 445 (discussed below) of the bracket 440 of the engagement system 195. The protruding features 224 can also be configured to receive one or more coupling features (e.g., fastening devices (e.g., screws), tabs) that allow the bracket 440 to be fixedly coupled to the top wall 227 of the frame 220 directly or indirectly (e.g., using the frame coupling features 444 discussed below).

[0038] In certain exemplary embodiments, the top wall 227 of the frame 220 can have a hole 221 therethrough. In this case, the hole 221 can be positioned toward the distal end of the frame 220 (e.g., the end of the frame 220-1 of the linear luminaire 190-1 that abuts the frame 220-2 of the linear luminaire 190-2 when the two linear luminaires 190 are joined together) and can be used to allow the proximal portion 551 of the pulling device 550 (discussed below) to pass therethrough so that the proximal portion 551 of the pulling device 550 can be pulled with a sufficient upward force to enable the engagement system 195 to pull the linear luminaire 190-2 toward the linear luminaire 190-1 in a properly aligned manner. In this case, the hole 221 is provided in a portion of the protruding feature 224.

[0039] Similarly, the inner surface of the left side wall 223 and the inner surface of the right side wall 222 can include one or more of a plurality of features to accommodate one or more components of the engagement system 195 and / or the tray 330. For example, the left side wall 223 can include a protrusion 226, a protrusion 229, a groove 213-3, and a groove 213-4 along its inner surface, wherein the groove 213-4 is also formed by the inner surface of the top wall 227. The protrusions 226 and the protrusions 229 can form a receiving space 212 for receiving an anchor 660 (e.g., anchor 660-1) and a distal end (e.g., distal end 335) of the tray 330, as shown in FIG. Figure 1F , 2A , 3A. Each of the slots 213-3 and 213-4 may be configured to receive the pin 880 (eg, the pin 880-4 received by the slot 213-3 and the pin 880-3 received by the slot 213-4), as shown in FIG. Figure 1F , 1H , 8A and 8B.

[0040] Each of the protrusion 226, the protrusion 229, the slot 213-3, and the slot 213-4 can be configured to allow a portion of the engagement system 195 or other portion of the linear luminaire 190 to be fixedly or movably disposed therein. For example, in this example, the distal end of the frame 220-1 for the linear luminaire 190-1 (in this case, the end of the frame 220-2 that abuts against the linear luminaire 190-2 when the two linear luminaires 190 are engaged together) can be configured such that the slot 213-3 fixedly retains the pin 880-4 therein and the slot 213-4 fixedly retains the pin 880-3 therein. In addition, the distal end of the frame 220-1 for the linear luminaire 190-1 can be configured such that the protrusion 226 and the protrusion 229 can slidably receive the anchor 660.

[0041] In contrast, in this example, the proximal end of the frame 220-2 for the linear luminaire 190-2 (in this case, the end of the frame 220-1 that abuts the linear luminaire 190-1 when the two linear luminaires 190 are joined together) can be configured such that the slot 213-3 can slideably receive the pin 880-4 therein and the slot 213-4 can slideably receive the pin 880-3 therein. In addition, the proximal end of the frame 220-2 for the linear luminaire 190-2 can be configured such that the protrusions 226 and the protrusions 229 are fixedly coupled to the anchor 660.

[0042] The various features along the inner surface of the right side wall 222 can be substantially the same as (as in this example) or different than the features along the inner surface of the left side wall 223. For example, the right side wall 222 can include a protrusion 225, a protrusion 228, a groove 213-1, and a groove 213-2 along its inner surface, with the groove 213-2 also formed by the inner surface of the top wall 227. The protrusions 225 and 228 can form a receiving space 211 for receiving an anchor 660 (e.g., anchor 660-2) and a distal end (e.g., distal end 333) of the tray 330, as shown in FIG. Figure 1A , 2A , 3A. The slot 213-1 and the slot 213-2 may each be configured to receive the pin 880 (eg, the pin 880-1 received by the slot 213-1 and the pin 880-2 received by the slot 213-2), as shown in FIG. Figure 1F , 1H , 8A and 8B.

[0043] Each of the protrusion 225, the protrusion 228, the slot 213-1, and the slot 213-2 can be configured to allow a portion of the engagement system 195 or other portion of the linear luminaire 190 to be fixedly or movably disposed therein. For example, in this example, the distal end of the frame 220-1 for the linear luminaire 190-1 (in this case, the end of the frame 220-2 that abuts against the linear luminaire 190-2 when the two linear luminaires 190 are engaged together) can be configured so that the slot 213-1 fixedly retains the pin 880-1 therein and the slot 213-2 fixedly retains the pin 880-2 therein. In addition, the distal end of the frame 220-1 for the linear luminaire 190-1 can be configured so that the protrusion 225 and the protrusion 228 can slidably receive the anchor 660.

[0044] Instead, in this example, the proximal end of the frame 220-2 for the linear luminaire 190-2 (in this case, the end of the frame 220-1 that abuts the linear luminaire 190-1 when the two linear luminaires 190 are joined together) can be configured such that the slot 213-1 can slideably receive the pin 880-1 therein and the slot 213-2 can slideably receive the pin 880-2 therein. In addition, the proximal end of the frame 220-2 for the linear luminaire 190-2 can be configured such that the protrusions 225 and the protrusions 228 are fixedly coupled to the anchor 660.

[0045] like Figure 3A and 3B As shown, each tray 330 of the linear light fixture 190 includes a top wall 331, a left side wall 334, and a right side wall 332. The space below the top wall 331 and between the left side wall 334 and the right side wall 332 forms a cavity 338, and various components of the linear light fixture 190 (e.g., circuit boards, light sources) can be located inside the cavity (but not shown here). In this example, the distal end 335 of the left side wall 334 has a generally hook shape to engage the anchor 660 and / or the protrusion of the frame 220 (e.g., protrusion 226). Similarly, in this example, the distal end 333 of the left side wall 332 has a generally hook shape to engage the anchor 660 and / or the protrusion of the frame 220 (e.g., protrusion 225).

[0046] In this case, the top wall 331, the left side wall 334, and the right side wall 332 are substantially planar. Moreover, in this example, the left side wall 334 and the top wall 331 of the tray 330 form an obtuse angle 337, and the right side wall 332 and the top wall 331 of the tray 330 form an obtuse angle 336. Angle 337 and angle 336 can be the same or different from each other. In alternative embodiments, the top wall 331, the left side wall 334, and / or the right side wall 332 can be non-planar (e.g., curved, made of multiple non-planar pieces). Additionally or alternatively, angle 337 and / or angle 336 can be acute or vertical angles instead of obtuse angles.

[0047] In this case, the various components of the exemplary engagement system 195 are located outside of the cavity 338 formed by the walls of the tray 330. In other words, the various components of the engagement system 195 are located above the top surfaces of the top wall 331, the left side wall 334, and the right side wall 332 of the tray 330 and within the cavity 254 formed by the frame 220.

[0048] Referring to the exemplary engagement system 195 of the lighting system 100 , the engagement system 195 in this example includes a bracket 440 , a pulling device 550 , two anchors 660 , a gripper 770 , and four pins 880 . Figures 4A to 4CThe illustrated bracket 440 includes a body 443 having an extension 441 at its proximal end, a traction device receiving feature 442 disposed in the extension 441, a frame receiving feature 445 in the form of extensions 446 and 447 (each extending upward from either side of the body 443 along the length of the body 443), and one or more frame coupling features 444 (in this case, frame coupling feature 444-1 and frame coupling feature 444-2).

[0049] Body 443 and extension 441 are planar in this case. In alternative embodiments, body 443 and / or extension 441 may be non-planar (e.g., curved, made from multiple non-planar pieces). Angle 449 is formed between body 443 and extension 441. In this case, angle 449 is an obtuse angle. In alternative embodiments, angle 449 may be an acute angle, or body 443 and extension 441 may be planar with respect to each other. Angle 449 may be configured to help reduce the amount of sufficient pulling force on the proximal end of proximal portion 551 of pulling device 550 to join linear luminaire 190-2 to linear luminaire 190-1.

[0050] The traction device receiving feature 442 disposed in the extension 441 is configured to be slidably coupled directly or indirectly to the proximal portion 551 of the traction device 550. The traction device receiving feature 442 can take any of a variety of forms. For example, in this case, the traction device receiving feature 442 can be a hole that passes through the thickness of the extension 441. In some cases, the proximal portion 551 of the traction device 550 can be directly disposed within the traction device receiving feature 442. In alternative embodiments, such as in this example (in Figure 1D and 1F ), the proximal portion 551 of the stretching device 550 is arranged directly within the gripping member 770, which is fixedly arranged in the stretching device receiving feature 442.

[0051] As discussed above, in this case, the frame receiving features 445 are in the form of extensions 446 and 447 that each extend upward (e.g., vertically) from either side of the body 443 along the length of the body 443. The extensions 446, 447, and the body 443 form a channel 448 in which the frame 220 of the linear luminaire 190 to be engaged (and more specifically, one or more protruding features 224 extending from the bottom surface of the top wall 227 of the frame 220) can slide. In this example, the protruding features 224 of the frame 220-2 of the linear luminaire 190-2 are configured to slide within the channel 448 when the linear luminaire 190-2 is pulled toward the linear luminaire 190-1 (when a sufficiently large upward force (e.g., applied by a user) pulls on the distal end of the distal portion 551 of the pulling device 550).

[0052] One or more frame coupling features 444 of bracket 440 are configured to be fixedly coupled to frame 220 of one of linear luminaires 190. In this example, frame coupling features 444 of bracket 440 are configured to be fixedly coupled to frame 220-1 of linear luminaire 190-1. Each frame coupling feature 444 can have any of a variety of configurations to allow frame coupling feature 444 to be directly or indirectly coupled to frame 220 of linear luminaire 190. In this case, frame coupling feature 444-1 and frame coupling feature 444-2 are in the form of holes that pass through the thickness of body 443 of bracket 440. In this way, a separate coupling feature (e.g., a screw) can be used to engage frame coupling feature 444 and a complementary coupling feature (e.g., a recess) in top wall 227 of frame 220.

[0053] With this configuration, the body 443 of the bracket 440 has a length sufficient to allow its distal end to be positioned within the cavity 254 formed by the frame 220 (in this case, frame 220-1) of one linear luminaire 190 (in this example, linear luminaire 190-1 fixed to the structure), while its proximal end extends beyond the frame 220-1 to slidably engage the frame 220 (in this case, frame 220-2) of a linear luminaire 190 (in this case, linear luminaire 190-2) being added to the linear lighting system 100.

[0054] The pulling device 550 of the engagement system 195 is configured to act as a mechanism that pulls the linear luminaire 190 being engaged to the linear lighting system 100 when sufficient upward force is applied to the proximal portion of the pulling device 550. The pulling device 550 may have any of a variety of structures. For example, in this case, the pulling device 550 has a Y-shaped configuration, wherein the proximal portion 551 forms the base of the Y, one distal portion 552-1 forms one line in the fork of the Y, and the other distal portion 552-2 forms the other line in the fork of the Y. In certain exemplary embodiments, the pulling device 550 is made of a material that does not stretch when a pulling force is applied to the material. For example, the pulling device 550 may be an airplane-shaped cable or made of the same material as an airplane-shaped cable.

[0055] Proximal portion 551 of pulling device 550 can be configured to be pulled with sufficient force to pull one linear light fixture 190 (e.g., linear light fixture 190-2) toward another linear light fixture 190 (e.g., linear light fixture 190-1). For example, proximal portion 551 of pulling device 550 can have a length sufficient to extend through gripper 770, through hole 221 in top wall 227 in frame 220, and extend beyond cavity 298 at the top of frame 220.

[0056] Each of the distal portions 552 (in this case, distal portion 552-1 and distal portion 552-2) of the pulling device 550 can be configured to couple to an anchor 660 that is fixedly coupled to a linear luminaire 190 (e.g., linear luminaire 190-2) that is being joined to a linear lighting system 100 (which includes linear luminaire 190-1), which can be anchored to a structure (e.g., a ceiling). The proximal portion 551 and any distal portion 552 can share a connection point 556. Some or all of the pulling device 550 can be rigid. Additionally or alternatively, some or all of the pulling device 550 can be flexible.

[0057] The anchor 660 of the engagement system 195 can be configured to serve a number of purposes. For one example, the anchor 660 can be configured to be fixedly coupled to a linear luminaire 190 (e.g., linear luminaire 190-2) that is being engaged to the linear lighting system 100. For another example, the anchor 660 can be configured to be slidably coupled to a linear luminaire 190 (e.g., linear luminaire 190-1) that is already engaged to the linear lighting system 100. For yet another example, the anchor 660 can be configured to be fixedly coupled to the distal end of the distal portion 552 of the pulling device 550.

[0058] As discussed above, the exemplary engagement system 195 can include a plurality of anchors 660. In such cases, the configuration of one anchor 660 (e.g., anchor 660-1) can be the same or different than the configuration of one or more other anchors 660 in the engagement system 195. In this example, anchor 660-1 and anchor 660-2 are configured identically to one another.

[0059] Anchor 660 can have any of a variety of configurations suitable for performing the functions of anchor 660 described above. In this example, FIG. 6A to FIG. 6E The anchor member 660 has an upper portion 662 and a lower portion 661. In this case, the upper portion 662 has a length, width, and height that are less than the length, width, and height of the lower portion 661. The upper portion 662 is substantially formed into a rectangular cuboid having a chamfered edge 655 along the top of the rear surface 654.

[0060] In this case, the lower portion 661 includes a left front section 663-1, a right front section 663-2, a left rear section 664-1, and a right rear section 664-2. The left front section 663-1 and the right front section 663-2 each substantially form a rectangular cuboid, and the left rear section 664-1 and the right rear section 664-2 each substantially form a cuboid having non-orthogonal angles. The front section 663 abuts against the rear section 664. The left front section 663-1 and the left rear section 664-1 are separated from the right front section 663-2 and the right rear section 664-2 by a gap 667.

[0061] In addition, there is a channel 665-1 that passes through the left front section 663-1 and the left rear section 664-1. Channel 665-1 passes along a diagonal line, starting from the top and toward the outside of the lower portion 661 and ends at a gap 667. Similarly, there is a channel 665-2 that passes through the right front section 663-2 and the right rear section 664-2. Channel 665-2 passes along a diagonal line, starting from the top and toward the outside of the lower portion 661 and ends at a gap 667. Each channel 665 has substantially the same characteristics (for example, a tubular shape with the same diameter and length). In alternative embodiments, one or more characteristics of one channel 665 may be different from one or more corresponding features of another channel 665.

[0062] The upper portion 662 of the anchor is configured to engage with one or more protrusions of the plurality of frames 220. In this case, as Figure 1F , 1H, 2A, and 6A to 6E, one side of the upper portion 662 of the anchor 660-1 engages (e.g., is disposed within, is coupled to) the protrusion 225 of the frame 220-1 of one linear light fixture 190-1, and the opposite side of the upper portion 662 of the anchor 660-1 engages (e.g., is disposed within, is directly or indirectly coupled to) the protrusion 225 of the frame 220-2 of another linear light fixture 190-2. Similarly, one side of the upper portion 662 of the anchor 660-2 engages (e.g., is disposed within, is coupled to) the protrusion 226 of the frame 220-1 of one linear light fixture 190-1, and the opposite side of the upper portion 662 of the anchor 660-2 engages (e.g., is disposed within, is directly or indirectly coupled to) the protrusion 226 of the frame 220-2 of another linear light fixture 190-2.

[0063] Similarly, at least a portion of the lower portion 661 of the anchor 660 is configured to engage with one or more protrusions of the plurality of frames 220. In this case, as shown in FIG. Figure 1F , 1H , 2A and 6A to 6E, a rear segment 664 (e.g., the right rear segment 664-2) of the lower portion 661 of the anchor 660-1 engages (e.g., is arranged within, coupled to) a protrusion 228 of a frame 220-1 of one linear luminaire 190-1, and another rear segment 664 (the left rear segment 664-1) of the lower portion 661 of the anchor 660-1 engages (e.g., is arranged within, directly or indirectly coupled to) a protrusion 229 of a frame 220-2 of another linear luminaire 190-2. Similarly, one rear segment 664 (e.g., the left rear segment 664-1) of the lower portion 661 of the anchor 660-2 engages (e.g., is disposed within, is coupled to) a protrusion 229 of a frame 220-1 of one linear light fixture 190-1, and another rear segment 664 (e.g., the right rear segment 664-2) of the lower portion 661 of the anchor 660-2 engages (e.g., is disposed within, is directly or indirectly coupled to) a protrusion 229 of a frame 220-2 of another linear light fixture 190-2.

[0064] In this way, the proximal half of the anchor 660-1 can be slidably disposed in the distal portion of the receiving space 211 of the frame 220-1 of the linear light fixture 190-1, and the distal half of the anchor 660-1 can be fixedly disposed in the proximal portion of the receiving space 211 of the frame 220-2 of the linear light fixture 190-2. Similarly, the proximal half of the anchor 660-2 can be slidably disposed in the distal portion of the receiving space 212 of the frame 220-1 of the linear light fixture 190-1, and the distal half of the anchor 660-2 can be fixedly disposed in the proximal portion of the receiving space 212 of the frame 220-2 of the linear light fixture 190-2.

[0065] The channel 665 through the anchor 660 can be used for one or more of a number of purposes. For example, the channel 665 through the anchor 660 can be used to receive a separate coupling feature (e.g., a screw, a rivet) to fixedly couple the anchor 660 to the frame 220. As another example, the channel 665 through the anchor 660 can be used to receive the distal end of the distal portion 552 of the traction device 550. In this case, the channel 665 can be referred to as a traction device coupling feature 665.

[0066] The grip 770 is another component of the engagement system 195. The grip 770 can be configured to serve a variety of purposes. For example, the grip 770 can be configured to help guide the proximal portion 551 of the traction device 550 when the proximal end of the proximal portion 551 is pulled (e.g., by a user) when the engagement system 195 is being implemented to extend the linear lighting system 100. For another example, the grip 770 can be configured to have a ratchet type capability that prevents the traction device 550 from being released or otherwise retracted therethrough. In other words, the grip 770 can be configured to prevent or significantly reduce the formation of slack in the traction device 550 between the grip 770 and the anchor 660.

[0067] The gripper 770 may have any of a variety of configurations suitable for performing the functions of the gripper 770 described above. In this example, Figures 7A to 7D The gripper 770 has a channel 775 disposed therein that passes through the length of the gripper 770. Also in this example, the gripper 770 has a cylindrical body 771 and a relatively smaller (e.g., shorter, smaller diameter) cylindrical extension 773 that extends from a distal wall 774 of the body 771 to a top surface 776 thereof. In alternative embodiments, the body 771 and the extension 773 can have any of a number of other features (e.g., different cross-sectional shapes, different lengths when viewed from above). In some cases, the top surface 776 of the cylindrical extension 773 can be rounded or smoothed to avoid cutting into the traction device 550.

[0068] The channel 775 has an end at the distal end of the extension 773. The inner wall 779 of the extension 773 defines the portion of the channel 775 located within the extension 773. When the channel 775 transitions from the extension 773 to the body 771, the width of the channel 775 defined by the inner wall 778 becomes smaller than the width of the channel 775 located within the extension 773. In addition, when viewed from above at this point, the cross-sectional shape of the channel 775 is square. In contrast, at the proximal end of the body 771, the width of the channel 775 at the proximal side wall 772 is greater than the width of the channel 775 within the extension 773. In this case, the portion of the channel 775 at the proximal end is defined in the side wall of the body 771. In this way, the central axis of the channel 775 can be different from the central axis of the body 771. In other words, the channel 775 in the gripper 770 deviates from the central axis along the length of the gripper 770. Furthermore, the cross-sectional shape of the channel 775 along the central axis thereof at the proximal end of the body 771 is circular.

[0069] In certain exemplary embodiments, the gripping member 770 may include a component or mechanism (e.g., a ratchet system with a one-way locking gear) that will allow the proximal portion 551 of the pulling device 550 to be pulled out of the linear light fixture 190-2 and through the hole 221 in the top wall 227 of the frame 220-1 of the linear light fixture 190-1, while also preventing the pulling device 550 from being pulled in the opposite direction. In this case, the component or mechanism may also include a release that will allow the pulling device 550 to be pulled in the opposite direction (in this example, toward the linear light fixture 190-2).

[0070] In some cases, the grip 770 can include one or more coupling features (e.g., a hole through the body 771, mating threads disposed on an outer surface of the body 771 toward the proximal end of the body 771) that can be configured to complement one or more coupling features on the extension 441 of the bracket 440. In this manner, the grip 770 can be coupled directly or indirectly to the extension 441 of the bracket 440. In alternative embodiments, the grip 770 can be positioned at other locations relative to the linear luminaire 190 and / or the linear lighting system 100 (e.g., above the hole 221 in the frame 220).

[0071] Pin 880 is an optional component of coupling system 195. As discussed above, exemplary coupling system 195 may include none, one, or multiple pins 880. Pin 880 may be configured to serve one or more purposes. For example, pin 880 may be configured to couple (e.g., fixedly, slidably) to a linear luminaire 190 (e.g., linear luminaire 190-2) that is coupled to linear lighting system 100. As another example, pin 880 may be configured to couple (e.g., slidably, fixedly) to a linear luminaire 190 (e.g., linear luminaire 190-1) that is already coupled to linear lighting system 100. In this manner, pin 880 may be complementary to one or more anchors 660 that are part of coupling system 195. Any pin 880 that is part of coupling system may be positioned at different locations around the end of frame 220 relative to the location of anchor 660 to help stabilize and secure the overall coupling between linear luminaires 190 that are being coupled to each other.

[0072] The pin 880 can have any of a variety of configurations. For example, in this case, the pin 880 can be slightly conical in shape or a tapered cylinder. Specifically, in this example, Fig. 8A and 8B The pin 880 has a body 882 defined by one end 881 and an opposite end 883. The diameter of the end 883 is greater than the diameter of the end 881, which causes the body 882 to taper. Moreover, the ends 881 and 883 are rounded, making it easier for the pin to be received by the slots (e.g., slots 213-3, 213-4) in the frame 220 of the linear light fixture 190. Fig. 8A and 8B With the configuration of pin 880 shown, end 883 (the end having the larger diameter) can be manually (e.g., by a user) inserted into a slot in the frame 220 of one linear light fixture 190 being engaged. This allows end 881 (having the smaller diameter) to extend beyond the frame 220 to be received by a corresponding slot in the frame 220 of the other linear light fixture 190 being engaged.

[0073] In alternative embodiments, the pin 880 can be cylindrical without any taper in the body 882. Additionally or in the alternative, the pin 880 can have an end 881 and / or an end 883 that are not rounded. When the engagement system 195 has multiple pins 880, the configuration (e.g., length, taper, diameter of each end) of one pin 880 can be the same or different than the configuration of one or more other pins 880 in the engagement system 195. In some cases, the slot 213 can include a detent or other feature to act as a stop to limit the amount that the pin 880 can be inserted into the slot 213.

[0074] How can the various components of the joint system 195 be used to join such as Figures 1A to 8B In the detailed example of two linear light fixtures 190 shown, linear light fixture 190-1 can be attached to a fixture (e.g., a ceiling), and linear light fixture 190-2 is being coupled to linear light fixture 190-1. A user can fixedly couple bracket 440 to the distal end of the bottom surface of top wall 227 of frame 220-1 of linear light fixture 190-1. Prior to doing so, gripper 770 can be coupled directly or indirectly to extension 441 of bracket 440.

[0075] In addition, the distal end of the anchor 660-1 can be fixedly disposed in the proximal portion of the receiving space 211 of the frame 220-2 of the linear light fixture 190-2, and the distal half of the anchor 660-2 can be fixedly disposed in the proximal portion of the receiving space 212 of the frame 220-2 of the linear light fixture 190-2. Before or after performing this step, the distal end of the distal portion 552-1 of the traction device 550 can be fixedly coupled to one of the channels 665 of the anchor 660-1 (channel 665-1, also referred to as traction device coupling feature 665-1). Similarly, the distal end of the distal portion 552-2 of the traction device 550 can be fixedly coupled to one of the channels 665 of the anchor 660-2 (channel 665-2, also referred to as traction device coupling feature 665-2).

[0076] Each pin 880 may be inserted into one of the slots 213 in the frame 220 of the linear light fixture 190-1 or the linear light fixture 190-2. For example, the end 883 of the pin 880-1 may be inserted into the slot 213-1 at the distal end of the frame 220-1 of the linear light fixture 190-1 such that the end 881 of the pin 880-1 extends beyond the distal end of the frame 220-1. The end 883 of the pin 880-2 may be inserted into the slot 213-2 at the distal end of the frame 220-2 of the linear light fixture 190-2 such that the end 881 of the pin 880-2 extends beyond the distal end of the frame 220-2. The end 883 of the pin 880-3 may be inserted into the slot 213-3 at the distal end of the frame 220-2 of the linear light fixture 190-2 such that the end 881 of the pin 880-3 extends beyond the distal end of the frame 220-3. End 883 of pin 880 - 4 may be inserted into slot 213 - 4 at the distal end of frame 220 - 1 of linear light fixture 190 - 1 such that end 881 of pin 880 - 4 extends beyond the distal end of frame 220 - 1 .

[0077] When the foregoing steps are completed, the distal end of the bracket 440 (extending beyond the distal end of the frame 220-1 of the linear light fixture 190-1) can be positioned below the bottom surface of the top wall 227 of the frame 220-2 of the linear light fixture 190-2. Then, the proximal end of the proximal portion 551 of the pulling device 550 can be inserted through the channel 775 of the gripping member 770, enter the extension 773 and exit the body 771. After the proximal end of the proximal portion 551 of the pulling device 550 exits the channel 775 of the gripping member 770, the proximal end of the proximal portion 551 of the pulling device 550 can be pulled through the hole 221 in the frame 220-1 of the linear light fixture 190-1.

[0078] When sufficient upward force is applied to the proximal end of the proximal portion 551 of the pulling device 550, the linear luminaire 190-2 slides along the bracket 440 toward the linear luminaire 190-1. As the linear luminaire 190-2 approaches the linear luminaire 190-1, the proximal end of the anchor 660-1 engages with the distal ends of the protrusions 225 and 228 of the frame 220-1 of the linear luminaire 190-1, thereby filling the distal end of the receiving space 211 of the frame 220-1 of the linear luminaire 190-1. Similarly, the proximal end of the anchor 660-2 engages with the distal ends of the protrusions 226 and 229 of the frame 220-1 of the linear luminaire 190-1, thereby filling the distal end of the receiving space 212 of the frame 220-1 of the linear luminaire 190-1.

[0079] At about the same time, the extended end 881 of the pin 880 is received by the corresponding slot 213 of the frame 220 of the other linear lighting fixture 190. In this example, when the linear fixture 190-2 is pulled toward the linear fixture 190-1 using the engagement system 195, the end 881 of the pin 880-1 slides into the slot 213-1 at the proximal end of the frame 220-2 of the linear fixture 190-2. When the linear fixture 190-2 is pulled toward the linear fixture 190-1 using the engagement system 195, the end 883 of the pin 880-2 slides into the slot 213-2 at the distal end of the frame 220-1 of the linear fixture 190-1. When linear light fixture 190-2 is pulled toward linear light fixture 190-1 using engagement system 195, end 883 of pin 880-3 slides into slot 213-3 at the distal end of frame 220-1 of linear light fixture 190-1. When linear light fixture 190-2 is pulled toward linear light fixture 190-1 using engagement system 195, end 883 of pin 880-4 may be inserted into slot 213-4 at the proximal end of frame 220-2 of linear light fixture 190-2.

[0080] Ultimately, the proximal end of the frame 220-2 of the linear luminaire 190-2, guided by the various components of the engagement system 195 (e.g., pins 880, brackets 440, anchors 660), abuts against the distal end of the frame 220-1 of the linear luminaire 190-1. In this manner, the engagement system 195 significantly reduces or eliminates any light leakage between the linear luminaire 190-1 and the linear luminaire 190-2 of the linear lighting system 100.

[0081] In certain exemplary embodiments, the use of the joining system 195 to join the linear luminaire 190-1 and the linear luminaire 190-2 in the linear lighting system 100 does not interfere with any other aspects of installing the linear luminaire 190-2. For example, when the various components of the joining system 195 are coupled to the frame 220-2 of the linear luminaire 190-2, and before the linear luminaire 190-2 is pulled toward the linear luminaire 190-1 to join the two components together, the following actions may be performed: any wiring connection and pulling of wires within and / or through the cavity 254 of the frame 220-2 of the linear luminaire 190-2.

[0082] In certain exemplary embodiments, the various components of the exemplary engagement system 195 (e.g., bracket 440, anchor 660, pin 550) may be installed without the use of tools. Additionally or alternatively, adjacent linear light fixtures 190 may be engaged using the exemplary engagement system 195 without the use of tools. Additionally or alternatively, adjacent linear light fixtures 190 that have been engaged using the exemplary engagement system 195 may be separated from one another without the use of tools.

[0083] Fig. 9 900 is a block diagram of another linear lighting system according to certain exemplary embodiments. Figures 1A to 9 , Fig. 9 The linear lighting system 900 includes a plurality of linear luminaires 990 (e.g., linear luminaire 990-1, linear luminaire 990-2, linear luminaire 990-3, linear luminaire 990-N) and a plurality of joining systems 995 (e.g., joining system 995-1, joining system 995-2, joining system 995-(N-1)). Fig. 9 The linear luminaire 990 and the engagement system 995 of the linear lighting system 900 are substantially the same as the linear luminaire 190 and the engagement system 195 discussed above with respect to FIGS. 1-8B .

[0084] In this example, the distal end of linear luminaire 990-1 and the proximal end of linear luminaire 990-2 are joined using joining system 995-1. Furthermore, the distal end of linear luminaire 990-2 and the proximal end of linear luminaire 990-3 are joined using joining system 995-2. The joining of linear luminaire 990-1, linear luminaire 990-2, and linear luminaire 990-3 using joining system 995-1 and joining system 995-2 forms linear luminaire 999, which can continue to be expanded using additional exemplary joining systems 995. In this example, linear luminaire 999 can be expanded to include N linear luminaires 990, which requires the use of N-1 exemplary joining systems 995.

[0085] In some cases, if adjacent linear fixtures 990 of a linear luminaire 999 need to be separated (e.g., to replace components of a linear fixture 990 for maintenance purposes), the exemplary engagement system can be configured to allow such separation without the use of tools. When the cause of separation of the previously engaged linear fixture 990 has been resolved, the linear fixtures 990 can be reengaged by applying a sufficient pulling force to the distal end of the distal portion 551 of the pulling device 550 that is the same as the pulling force used to initially engage the linear fixtures 990. Reengagement can be achieved with little or no adjustment or resetting of the pins 880, anchors 660, and / or grippers 770. The process of separating and reengaging adjacent linear fixtures 990 can be repeated multiple times without reducing the effectiveness of the exemplary engagement system 995 in significantly reducing or eliminating light leakage between the engaged linear fixtures 990.

[0086] Exemplary embodiments may be used to allow two linear luminaires to be joined end-to-end to one another in a manner in which light leakage between them is significantly reduced or eliminated. Exemplary embodiments may be utilized when one of the linear luminaires is mounted relative to a structure (e.g., a ceiling) and the other linear luminaire is wired for integration into the resulting linear luminaire. Exemplary embodiments may be used with linear luminaires having any of a plurality of sizes and / or features. Exemplary embodiments may be installed and implemented without the use of tools. Exemplary embodiments may be used for new installations of linear luminaires as well as retrofitting of existing linear luminaires. Exemplary embodiments also provide numerous other benefits. Such other benefits may include, but are not limited to, increased ease of maintenance, greater ease of use, catering to user preferences, modularity, ease of installation, and compliance with industry standards applied to linear luminaires and the resulting linear luminaire when the linear luminaires are joined to one another.
