Technical Field
[0001] This utility model relates to the technical field of lighting fixtures, and in particular to a tool-free, replaceable structure for modular optical components of linear lighting fixtures. Background Technology
[0002] Existing linear lighting fixtures for office or commercial use (such as linear lights and light strips) typically employ an integrated design, meaning that the light-emitting surface and optical structure (such as lenses, diffusers, grilles, and seamless connections) of a single fixture are fixed. This design results in the light emission angle, light spot shape, visual effect, and long-term usage requirements (such as uniform wall washing, focused spotlighting, and dynamic wave lighting) being determined at the factory.
[0003] When distributors, designers, or end-users need to achieve diverse lighting effects in different scenarios (such as conference rooms, office areas, showrooms, etc.), they must purchase multiple different types of specialized luminaires. This not only significantly increases procurement costs and inventory pressure, but also makes it impossible to flexibly adjust to changes in demand after installation, lacking flexibility and personalized customization capabilities; therefore, this application proposes a tool-free, replaceable structure for modular optical components of linear luminaires. Utility Model Content

[0035] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.
[0036] like Figure 1-12 In this first embodiment, the tool-free, replaceable structure of the modular optical components for linear luminaires includes...
[0037] Light stand 10 is U-shaped;
[0038] The crossbeam plate 20 connects the two side walls of the lamp holder 10 and is integral with it. The crossbeam plate 20 has a limiting groove 21.
[0039] The lamp body 40 has both ends that slide into the limiting groove 21;
[0040] The lampshade 41 is slidably disposed on the U-shaped opening end of the lamp holder 10 and directly opposite the lampshade 41;
[0041] Two card plates 31 are respectively set on the two side walls of the lamp holder 10 and are integrated;
[0042] Several connectors 30 are slidably locked between two plates 31;
[0043] The first connector 50 and the second connector 60 are detachably and fixedly connected to both ends of the lamp holder 10, and are used to restrict the lamp body 10, lamp cover 41 and connector 30 on the lamp holder 10.
[0044] The first connector 50 has first inserts 56 on both sides of the side opposite to the lamp holder 10, forming a first slot 57 with the first connector 50; the second connector 60 has second inserts 66 on both sides of the side opposite to the lamp holder 10, forming a second slot 67 with the second connector 60; the first inserts 56 can be slidably inserted into the second slot 67, and the second inserts 66 can be slidably inserted into the first slot 57, so that the two adjacent lamp holders 10 are fixed in a horizontal position.
[0045] The first blocking plate 70 is detachably snapped onto the second connecting body 60;
[0046] The second blocking plate 80 is detachably attached to the first connecting body 50.
[0047] This embodiment is implemented as follows:
[0048] In use, this application allows the lamp holder 10 to be suspended by connecting to the ceiling rope via two connectors 30. The first connector 50 and the second connector 60 are fixed to the lamp holder 10, thus restricting the lamp body 10, lampshade 41, and connectors 30 to the lamp holder 10. The first blocking plate 70 and the second blocking plate 80 can respectively block the second connector 60 and the first connector 50, and can also be disassembled.
[0049] When it is necessary to connect the two lamp holders 10, the first end plate 70 and the second end plate 80 can be removed, the first insert 56 on the first connector 50 can be inserted into the second slot 67 on the second connector 60, and at the same time, the second insert 66 on the second connector 60 can be inserted into the first slot 57 on the first connector 50, so that the first connector 50 and the second connector 60 are connected, thereby realizing the connection between the two lamp holders 10.
[0050] This application can achieve the connection between two lamp holders 10, and the connection method is relatively simple and does not require the use of tools.
[0051] Please see Figure 3 , 4 9, 10, 11, 12, The first connecting body 50 is provided with a first extension plate 51, and the first extension plate 51 has a first threaded sleeve 52 that penetrates the first extension plate 51. The middle plate of the lamp holder 10 has a first through hole 53 corresponding to the position of the first threaded sleeve 52. The first connecting body 50 and the lamp holder 10 are fixed by a screw that passes through the first through hole 53 and is connected to the first threaded sleeve 52.
[0052] In this application, the connection between the first connector 50 and the lamp holder 10 is mainly achieved by a screw passing through the first through hole 53 and being threadedly connected to the first threaded sleeve 52 on the first extension plate 51 of the first connector 50, thereby fixing the first connector 50 and the lamp holder 10.
[0053] Please see Figure 3 , 4 9, 10, 11, 12, the two side walls of the first connecting body 50 are also connected by the first connecting plate 54. The first connecting plate 54 is provided with a first positioning post 55. The second blocking plate 80 is provided with a third clamping plate 81 and a fourth clamping plate 82. The third clamping plate 81 and the fourth clamping plate 82 are both provided with clamping grooves. The clamping groove of the third clamping plate 81 is clamped on the outer wall of the first positioning post 55, and the clamping groove of the fourth clamping plate 82 is clamped on the outer wall of the first threaded sleeve 52.
[0054] This application uses the clamping groove of the third clamping plate 81 on the second blocking plate 80 to clamp the outer wall of the first positioning post 55, and the clamping groove of the fourth clamping plate 82 to clamp the outer wall of the first threaded sleeve 52, so that the second blocking plate 80 can be disassembled and installed by pushing and pulling during operation.
[0055] Please see Figure 5 , 6 7, 8, 11, 12, The second connecting body 60 is provided with a second extension plate 61, and the second extension plate 61 has a second threaded sleeve 62 that penetrates the second extension plate 61. The middle plate of the lamp holder 10 has a second through hole 63 corresponding to the position of the second threaded sleeve 62. The second connecting body 60 and the lamp holder 10 are fixed by a screw that penetrates the second through hole 63 and is connected to the second threaded sleeve 62.
[0056] In this application, the connection between the second connector 60 and the lamp holder 10 is mainly achieved by a screw passing through the second through hole 63 and being threadedly connected to the second threaded sleeve 62 on the second extension plate 61 of the second connector 60, thereby fixing the second connector 60 to the lamp holder 10.
[0057] Please see Figure 5 , 6 7, 8, 11, 12. The two side walls of the second connecting body 60 are also connected by a second connecting plate 64. The second connecting plate 64 is provided with a second positioning post 65. The first blocking plate 70 is provided with a first clamping plate 71 and a second clamping plate 72. Both the first clamping plate 71 and the second clamping plate 72 have clamping grooves. The clamping groove of the first clamping plate 71 clamps onto the outer wall of the second positioning post 65, and the clamping groove of the second clamping plate 72 clamps onto the outer wall of the second threaded sleeve 62.
[0058] This application uses the clamping groove of the first clamping plate 61 on the first blocking plate 70 to clamp the outer wall of the second positioning post 65, and the clamping groove of the second clamping plate 62 to clamp the outer wall of the second threaded sleeve 62, so that the first blocking plate 70 can be disassembled and installed by pushing and pulling during operation.
