[0001] This utility model relates to the field of LED lighting technology, specifically, to a strip light. Background Technology

[0002] In the field of indoor lighting and decoration, strip lights are widely used in commercial spaces, office areas and home environments due to their simple appearance and uniform lighting effect, so as to achieve basic lighting and atmosphere creation functions.

[0003] However, current strip lights on the market typically integrate the light source module and control circuitry into a single unit within the lamp housing. This integrated design makes it difficult to replace, maintain, and debug strip lights later on. At the same time, the integrated design also greatly limits its functional expansion, making it impossible to easily add intelligent control modules to the lamp housing according to user needs, thus failing to meet diverse usage requirements.

The inner sides of the two side walls of the optical housing are provided with overlapping grooves, and the outer sides of the two side walls of the optical housing are provided with nesting grooves; the optical housing is covered by the top opening of the light source base plate, with the overlapping edge located in the overlapping groove; the two end caps are respectively covered by the two end openings of the light source base plate, and the parts of the two end caps corresponding to the overlapping grooves are inserted into the overlapping grooves; the nesting flanges formed on the opposite side walls of the bottom shell are respectively embedded in the nesting grooves provided on the outer sides of the two side walls of the optical housing; each end cap assembly covers one of the bottom shell baffles and the outer side of the end cap at the corresponding end of the bottom shell baffle.

[0006] According to one embodiment of the present invention, the cross-section of the nested flange is barbed, and the inner wall of the nested groove is an arc-shaped groove. After the barbed nested flange is embedded in the nested groove, it abuts against the arc-shaped inner wall of the nested groove.

[0007] According to one embodiment of the present invention, the optical component further includes a heat sink, which covers the top opening of the light source base plate, and the two opposite edges of the heat sink are provided in the overlapping groove.

[0008] According to one embodiment of the present invention, the optical component further includes an optical plate; the optical plate is disposed between the heat sink and the bottom wall of the optical housing, and the two opposite edges of the optical plate are also disposed in the overlapping groove.

[0009] According to one embodiment of the present invention, the cross-section of the light source base plate is an isosceles trapezoid.

[0010] According to one embodiment of the present invention, an engagement groove is provided at the position corresponding to the end of the end cap and the end of the optical plate and the heat sink. The height of the engagement groove is adapted to the sum of the thicknesses of the optical plate and the heat sink.

The electrical and optical components are detachably connected through the precise fitting of nested flanges and recesses. The overlapping edge of the light source base plate and the overlapping groove of the optical housing further strengthen the modular combination within the optical component, allowing the optical component to be disassembled and installed independently of the electrical component. The two end cap components respectively cover the bottom shell baffle and the outer side of the optical component end cap, ensuring the overall structural sealing and providing convenience for individual maintenance of the two end components. This modular design eliminates the need to disassemble the entire light fixture during later replacement, maintenance, or debugging; only the problematic electrical or optical components can be operated individually, significantly reducing maintenance difficulty. Simultaneously, the independent electrical components provide ample space for functional expansion, allowing for the convenient addition of intelligent control modules and other expansion components within the bottom shell according to user needs, without altering the structure of the optical component. This flexibly meets diverse usage requirements and is more practical and adaptable than traditional integrated designs. Attached Figure Description

[0033] To further understand the utility model's content, features, and effects, the following embodiments are provided, along with detailed descriptions in conjunction with the accompanying drawings:

[0034] like Figure 1 As shown, Figure 1 This is a three-dimensional structural diagram of the strip light in this embodiment. This embodiment provides a strip light including: an electrical component 1, an optical component 2, and two end cap assemblies 3. The electrical component 1 and the optical component 2 are detachably connected, and the two end cap assemblies 3 are detachably connected to both ends of the electrical component 1 and the optical component 2 after connection. By separating the electrical component 1 and the optical component 2, each component can be independently assembled and disassembled. Combined with a detachable functional expansion structure, this simplifies the later maintenance process and allows for flexible addition or replacement of components according to user needs, meeting diverse usage scenarios. This solves the problems of difficult maintenance and limited functional expansion caused by the integrated design of the light source module and control circuit in traditional strip lights.

[0035] Please refer to the following: Figure 2 As shown, Figure 2 This is a three-dimensional structural diagram of the electrical component in this embodiment. The electrical component 1 includes a bottom shell 11, two bottom shell baffles 12, and a power module 13. The bottom shell 11 is hollow inside and has openings at the top and both ends. The opposite side walls of the bottom shell 11 extend inward to form nested flanges 111. The two bottom shell baffles 12 are respectively disposed at the openings at both ends of the bottom shell to seal the openings at both ends of the bottom shell. The power module 13 is fixed inside the bottom shell 11.

[0036] The bottom shell 11 is rectangular. When the two opposite sidewalls of the bottom shell 11 extend inward to form nested flanges 111, the nested flanges 111 are distributed along the length of the sidewalls, thus forming a long strip. The two bottom shell baffles 12 are made of metal. When the two bottom shell baffles 12 are respectively set at the openings at both ends of the bottom shell 11, the bottom shell baffles 12 provide end protection on the one hand, and provide a mounting base for the end cover assembly 3 on the other hand. The power module 13 can be fixed inside the bottom shell 11 with screws.

[0037] Please refer to the following: Figure 3-6 As shown, Figure 3 This is a three-dimensional structural diagram of the optical component in this embodiment; Figure 4 for Figure 3 A magnified view of part A in the middle; Figure 5 This is a cross-sectional view of the electrical and optical components assembled in this embodiment; Figure 6 for Figure 5A partially enlarged schematic diagram of part B. Optical component 2, serving as the light-emitting and optical control module, includes a light source base plate 21, a lamp plate 22, an optical housing 23, and end caps 24. The light source base plate 21 is hollow internally and open at the top and both ends, with its side walls extending outwards to form overlapping edges 211. The lamp plate 22 is fixed inside the light source base plate 21, and during installation, the light-emitting surface of the lamp plate 22 faces the opening at the top of the light source base plate 21, allowing light emitted from the lamp plate to exit through the opening. The lamp plate 22 is electrically connected to the power module 13. The optical housing 23 is made of a highly transparent material, is hollow internally, and open at the bottom and both ends. The inner sides of both side walls are provided with overlapping grooves 231 that are adapted to the overlapping edge 211, and the outer sides of both side walls are provided with nesting grooves 232 that are adapted to the nesting flange 111. When the optical housing 23 is covered on the top opening of the light source base plate 21, the overlapping edge 211 of the light source base plate 21 is precisely embedded in the overlapping groove 231 of the optical housing 23, so as to achieve a stable and detachable connection between the two. The end caps 24 are respectively covered on the two end openings of the light source base plate 21, and the part of the end cap 24 corresponding to the overlapping groove 231 is inserted into the overlapping groove 231, further reinforcing the connection between the optical housing 23 and the light source base plate 21.

[0038] When assembling the strip light, the nested flanges 111 formed on the opposite side walls of the bottom shell 11 are respectively embedded into the nested grooves 232 provided on the outer side walls of the optical shell 23. Then, the bottom shell 11 or the optical shell 23 is pushed so that the nested flanges 111 slide along the nested grooves 232. After the bottom shell 11 and the optical shell 23 are aligned, each end cap assembly 3 is then placed on the outer side of one of the bottom shell baffles 12 and the end cap 24 corresponding to the bottom shell baffle 12, thus completing the assembly of the strip light.

[0039] When the user needs to adjust the lighting effect, first remove the end cap assemblies 3, then gently push the optical component 2 or electrical component 1 along the length direction so that the nested flange 111 slides along the nested groove 232 to obtain the detached optical component 2, and remove the end caps 24 on both sides. At the same time, remove the optical housing 23 and replace it with a housing with a different light transmittance. There is no need to disassemble the electrical component 1, thus achieving quick adjustment of the optical function.

[0040] When maintenance is required, first remove the end cap assemblies 3, then gently push the optical component 2 or electrical component 1 along its length, causing the nested flange 111 to slide along the nested groove 232 until the optical component 2 and electrical component 1 disengage. This allows the optical component 2 to be separated from the electrical component 1, achieving rapid disassembly of the "electrical-optical" module. In this embodiment, the independent layout of the electrical component 1 and optical component 2 solves the pain point of "maintenance requires disassembly of the whole" in traditional integrated lamp bodies. If the power module 13 malfunctions, only the end cap assemblies 3 need to be removed, and the nested flange 111 needs to be slid along the nested groove 232 to separate the optical component 2 from the electrical component 1. Then, the power module 13 can be removed from the bottom shell 11 and replaced without separating the optical component 2, improving the convenience of maintenance. Alternatively, when it is necessary to expand the function of the strip lamp, the optical component 2 and electrical component 1 can be separated in the same way, and the functional module to be expanded can be installed in the bottom shell 11 and electrically connected to the lamp board 22.

[0041] For further details, please review. Figure 6 The cross-section of the nested flange 111 is barbed, with the hook facing the inner wall of the bottom shell 11. The inner wall of the nested groove 232 is an arc-shaped groove. When the barbed nested flange 111 is inserted into the nested groove 232, the barbed surface of the nested flange 111 abuts against the arc surface of the inner wall of the nested groove 232.

[0042] The arc of the nested groove 232 perfectly matches the barbed surface of the nested flange 111. This structure not only prevents the electrical component 1 from accidentally separating from the optical component 2 during use, but also retains the detachability. When disassembling, only a little force is needed to push the optical component 2 or the electrical component 1, and the barbed nested flange 111 can slide off along the nested groove 232 without the need for tools, further improving the convenience of maintenance.

[0043] For further details, please review. Figure 4 The optical component 2 also includes a heat sink 25, which covers the top opening of the light source base plate 21, and the two opposite edges of the heat sink 25 are also embedded in the overlapping groove 231 of the optical housing 23. That is, the two opposite edges of the heat sink 25 are attached to the bottom edge 211 of the light source base plate 21 and embedded in the corresponding overlapping groove 231.

[0044] The heat sink 25 can quickly conduct the heat generated by the light-emitting surface of the lamp board 22 to the outside, improve the heat dissipation efficiency, and prevent the lamp board 22 from decaying due to high temperature. At the same time, the heat sink 25 is located in the overlapping groove 231, which makes it easy to disassemble. If the user needs to upgrade the lamp board power, the end cover 24 can be removed directly and the original heat sink 25 can be replaced without replacing the entire optical component 2, thereby realizing the flexible expansion of the heat dissipation function.

[0045] Furthermore, the optical component 2 also includes an optical plate 26, which is disposed between the heat sink 25 and the bottom wall of the optical housing 23, and the two opposite edges of the optical plate 26 are also disposed in the overlapping groove 231.

[0046] The optical plate 26 can be selected as a diffuser, a spotlight, or a color temperature filter according to the needs. This design solves the problem of fixed optical functions of traditional lamp bodies. Users can flexibly replace the optical plate according to the scene. For example, in the office scene, replace it with a diffuser to reduce glare, in the exhibition hall scene, replace it with a spotlight to enhance key lighting, and in the home scene, replace it with a warm color temperature filter to create a warm atmosphere. Moreover, when replacing it, you only need to remove the end cover 24 to take out the old optical plate 26 and replace it with a new plate. The operation is simple and no other parts need to be modified.

[0047] Furthermore, the cross-section of the light source base plate 21 is an isosceles trapezoid. The two side walls of the light source base plate 21 can reflect the lateral light from the lamp plate 22. At the same time, the overlapping edges 21 extending outward from the two side walls of the light source base plate 21 are embedded in the overlapping grooves 231 of the optical housing 23, making the fit between the light source base plate 21 and the optical housing 23 more precise, less prone to displacement during installation, and more evenly distributed force during disassembly, thus avoiding component jamming.

[0048] Please refer to the following: Figure 7-8 As shown, Figure 7 This is a three-dimensional structural diagram of the end of the optical component in this embodiment; Figure 8 for Figure 7 A partially enlarged schematic diagram of part C. The end cap 24 is provided with a fitting groove 241 at the position corresponding to the ends of the optical plate 26 and the heat sink 25. The height of the fitting groove 241 is adapted to the sum of the thicknesses of the optical plate 26 and the heat sink 25. When the part of the end cap 24 corresponding to the overlapping groove 241 is inserted into the overlapping groove 241, the ends of the optical plate 26 and the heat sink 25 are just embedded in the fitting groove 241.

[0049] In addition, the two opposite edges of the heat sink 25 and the optical plate 26 are embedded in the overlapping groove 231 of the optical housing 23. When the end cap 24 is closed on the ends of the optical plate 26 and the heat sink 25, it is precisely embedded in the fitting groove 241. This not only fixes the ends of the optical plate 26 and the heat sink 25 to prevent displacement during use, but also does not affect disassembly. After removing the end cap 24, the optical plate 26 and the heat sink 25 can be freely removed, simplifying the maintenance steps.

[0050] Furthermore, a support frame 242 is provided at the position corresponding to the end of the end cap 24 and the end of the light source base plate 21. When the part of the end cap 24 corresponding to the overlapping groove 231 is inserted into the overlapping groove 231, the end of the light source base plate 21 is exactly located on the support frame 242.

[0051] The height of the supporting frame 242 is adapted to the height of the light source base plate 21. When the end cap 24 is installed at the ends of the optical plate 26, the heat sink 25 and the light source base plate 21, the top of the supporting frame 242 can provide end support for the light source base plate 21. This can effectively prevent the end of the light source base plate 21 from sagging and deforming, and enhance the overall structural stability of the optical component 2.

[0052] Please review Figure 2 Please refer to them together. Figure 9 As shown, Figure 9 This is a three-dimensional structural diagram of the end cap assembly in this embodiment. The end cap assembly 3 includes a cover body 31. The side of the cover body 31 facing the bottom shell baffle 12 is provided with at least two snap-fit ​​cylinders 311, which are located at both ends of the cover body 31. The bottom shell baffle 12 is provided with snap-fit ​​circular holes 121 that are adapted to the snap-fit ​​cylinders 311. The cover body 31 covers one of the bottom shell baffles 12 and the outer side of the end cap 24 at the corresponding end of the bottom shell baffle 12. Each snap-fit ​​cylinder 311 is snapped into the corresponding snap-fit ​​circular hole 121. This snap-fit ​​design does not require screws, and the end cap assembly 3 can be fastened or disassembled by hand. Compared with traditional screw fixing, the maintenance operation time can be shortened.

[0053] Furthermore, the end cap assembly 3 also includes at least two end cap magnets 32. The side of the cover body 31 facing the bottom shell baffle 12 is provided with at least two slots 312 that are adapted to the number and shape of the end cap magnets 32. The slots 312 are located at both ends of the cover body 31, and each slot 312 is provided with an end cap magnet 32. The bottom shell baffle 12 is made of metal. When the cover body 31 is covered by one of the bottom shell baffles 12 and the outside of the end cap 24 at the corresponding end of the bottom shell baffle 12, the end cap magnets 32 attract the bottom shell baffle 12, that is, the cover body 31 is fixed to the bottom shell baffle 12 by the attraction of the end cap magnets 32.

[0054] Please review Figure 1 The cover 31 is double-fixed with the end cap magnet 32 ​​and the snap-fit ​​cylinder 311, which not only prevents the cover 31 from falling off accidentally, but also does not affect disassembly. At the same time, the inner wall of the cover 31 has longitudinal grooves, which can add intelligent sensing modules (such as human body sensing and light sensing modules) inside the cover 31. The wires of the intelligent sensing module can be passed through the circular hole gap between the cover 31 and the bottom shell baffle 12 to connect to the internal power module 13 without modifying the original structure, thereby realizing the expansion of intelligent functions.

[0055] For further details, please review. Figure 2 The bottom wall of the bottom shell 11 is provided with a power mounting base 112, and the power module 13 is fixed in the power mounting base 112. The power mounting base 112 is groove-shaped, and the width of the groove is adapted to the width of the power module 13.

[0056] In summary, traditional strip lights suffer from difficult maintenance and limited functional expansion due to their integrated design. The strip light in this embodiment addresses these issues by firstly, through modular disassembly of the "electrical-optical-end cap" components, allowing for independent assembly and disassembly of each part without the need for overall disassembly during maintenance; and secondly, by using replaceable heat sinks, optical boards, and reserved functional expansion space, it meets users' diverse needs for lighting effects, heat dissipation capabilities, and intelligent functions, thereby significantly improving the practicality and flexibility of the strip light.
