[0002] Lighting is becoming increasingly integrated into people's lives. To prevent glare caused by extremely high brightness after light source reflection, existing reflector assemblies typically include a lens and an anti-glare shield on the reflector. During installation, the reflector is fixed to the outer casing, and then the lens and anti-glare shield are sequentially installed on the reflector. However, existing reflector assemblies have the following problems: the design and installation require consideration of the corresponding assembly relationships between the reflector, lens, and anti-glare shield, which complicates design and production, leading to complex product structures and even defects such as loosening, warping, and large assembly gaps.

[0003] Therefore, existing technological solutions cannot meet our requirements. Utility Model Content

[0004] The technical problem to be solved by the embodiments of this application is that the existing reflector cup assembly requires consideration of the corresponding assembly relationship of the reflector cup, lens and anti-glare cover during the design and installation, which brings inconvenience to the design and production, leads to the complexity of the product structure, and even causes defects such as loosening, warping, and large assembly gaps.

[0005] To address the aforementioned technical problems, this application provides a reflector assembly that employs the following technical solution: The lamp includes a lamp housing, at least one anti-glare cover, a reflector, and a lens. The lens is disposed on the reflector. The lamp housing has a mounting cavity and a fixing groove. The anti-glare cover is inserted into the fixing groove along the length of the lamp housing and abuts against the lens, thereby fixing the reflector and the lens in the mounting cavity.

[0006] Furthermore, the anti-glare shield includes a mounting part, one end of which is inserted into the fixing groove, and the other end of which abuts against the lens.

[0007] Furthermore, the anti-glare cover also includes an anti-glare part, one end of which is connected to the mounting part, and the other end of which abuts against the inner wall of the mounting cavity.

[0008] Furthermore, the anti-glare part is provided with an arc surface, and the two ends of the arc surface are respectively connected to the light-emitting surface of the lens and the inner wall of the mounting cavity.

[0009] Furthermore, the mounting cavity is provided with a first protrusion and a second protrusion, and the fixing groove is formed between the first protrusion and the second protrusion. The protruding length of the first protrusion is greater than the protruding length of the second protrusion.

[0010] Furthermore, the anti-glare shield also includes a positioning part, and the side of the lens abuts against the positioning part.

[0011] Furthermore, the light-emitting surface of the lens is a flat surface.

[0012] Furthermore, the lens and the reflector are connected by a snap fastener, the snap fastener including a slot on one of the lens and the reflector and a protrusion on the other.

[0013] Furthermore, the reflector assembly also includes at least two reflector supports, which are connected to the end of the reflector furthest from the lens.

[0014] This application provides a linear light, which adopts the following technical solution: It includes a light source and the reflector assembly, wherein the light source is disposed on the end of the reflector away from the lens and is located within the mounting cavity.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments.

[0021] Reference Appendix Figure 1 To be continued Figure 9 As shown in the figure, this application provides a reflector assembly that adopts the following technical solution: The assembly includes a lamp housing 1, at least one anti-glare cover 2, a reflector cup 3, and a lens 4. The lens 4 is mounted on the reflector cup 3. The lamp housing 1 has a mounting cavity 11 and a fixing groove 12. The anti-glare cover 2 is inserted into the fixing groove 12 along the length of the lamp housing 1 and abuts against the lens 4, thereby fixing the reflector cup 3 and the lens 4 within the mounting cavity 11. During installation, the anti-glare cover 2 can be inserted into the fixing groove 12 along the length of the lamp housing 1. Therefore, only the assembly tolerances of the reflector cup 3 and the lens 4 need to be controlled. The anti-glare cover 2 achieves a stable clamping of the reflector cup 3 and the lens 4 through insertion. The installation of the anti-glare cover 2 and the lamp housing 1 is simple, convenient, and quick, significantly improving production efficiency.

[0022] As attached Figure 3 To be continued Figure 6 As shown, in some embodiments, the anti-glare cover 2 includes a mounting portion 21. One end of the mounting portion 21 is inserted into the fixing groove 12, and the other end of the mounting portion 21 abuts against the lens 4. The end of the mounting portion 21 inserted into the fixing groove 12 can connect to the lamp housing 1, while the other end of the mounting portion 21 abutting against the lens 4 can fix and position the reflector 3 and the lens 4. This not only reduces the loosening problems that may occur in traditional fixing structures but also ensures that the relative positions of the reflector 3 and the lens 4 are fixed within the housing 1. Simultaneously, the two ends of the mounting portion 21 cooperate with the fixing groove 12 and the lens 4 respectively, forming a stable force-bearing structure, making the reflector assembly less prone to displacement during long-term use, thereby ensuring the stability and consistency of the lighting effect.

[0023] Furthermore, the mounting portion 21 and the fixing groove 12 are connected by an interference fit, ensuring that the anti-glare cover 2 is stable and does not loosen after assembly, while effectively preventing light leakage and improving illumination uniformity. The edge of the lens 4 fits tightly against the end face of the mounting portion 21, further enhancing sealing and optical performance. This structural design simplifies the assembly process, eliminates the need for additional fasteners, facilitates automated mass production, and reduces manufacturing costs.

[0024] As attached Figure 3 To be continued Figure 6As shown, in some embodiments, the anti-glare cover 2 further includes an anti-glare part 22, one end of which is connected to the mounting part 21, and the other end of which abuts against the inner wall of the mounting cavity 11. The anti-glare part 22 provides a smooth transition between the lens 4 and the lamp housing 1, thereby effectively reducing glare intensity and improving visual comfort in the illuminated area. Simultaneously, the inner wall of the mounting cavity 11 helps to limit the anti-glare cover 2 and the lens 4, reducing stress concentration, enhancing the overall structural strength of the anti-glare cover 2, and preventing axial rotation of the anti-glare cover 2 and the lens 4 during use. Furthermore, the middle portion of the anti-glare part 22 is free from obstructions such as grilles, allowing the linear light to emit continuous light without casting shadows on the illuminated object, thus improving the uniformity of the illumination.

[0025] As attached Figure 3 To be continued Figure 6 As shown, in some embodiments, the anti-glare portion 22 is provided with an arc surface 221, the two ends of which are connected to the light-emitting surface 41 of the lens 4 and the inner wall of the mounting cavity 11, respectively. The arc-shaped anti-glare portion 22 enables the scattered light rays from the edge of the light-emitting surface 41 of the lens 4 to undergo smooth refraction and deflection when passing through the arc surface 221, avoiding the formation of sharp light spots or dark areas at the connection between the anti-glare portion 22 and the inner wall of the mounting cavity 11, softening the light distribution, and improving the uniformity of the illumination light.

[0026] Furthermore, the arc surface 221 extends from the anti-glare part 22 to the mounting part 21, making one side of the anti-glare cover 2 integrally arc-shaped, further enhancing the anti-glare effect. At the same time, the arc-shaped anti-glare part 22 and the mounting part 21 on one side allow the end of the anti-glare part 22 away from the mounting part 21 to abut against the inner wall of the mounting cavity 11, while the end of the mounting part 21 away from the anti-glare part 22 abuts against the light-emitting surface 41, enhancing the overall structural strength of the anti-glare cover 2 and preventing the anti-glare cover 2 and the lens 4 from rotating axially during use.

[0027] As attached Figure 3 To be continued Figure 6As shown, in some embodiments, the mounting cavity 11 is provided with a first protrusion 13 and a second protrusion 14, and a fixing groove 12 is formed between the first protrusion 13 and the second protrusion 14. The protruding length of the first protrusion 13 is greater than the protruding length of the second protrusion 14, making the fixing groove 12 step-shaped. When the mounting part 21 of the anti-glare cover 2 is inserted into the fixing groove 12, the first protrusion 13 can provide a stronger limiting effect on the upper outer end of the mounting part 21, while the second protrusion 14 can abut against the lower outer end of the mounting part 21. Through the cooperation of the protrusions of different lengths at both ends, the stability of the mounting part 21 in the fixing groove 12 is ensured, and excessive compression deformation of the mounting part 21 during assembly due to excessive protrusion is avoided. It can also replace the multi-section splicing structure of the prior art, simplifying installation and meeting the needs of large-scale rapid replacement of anti-glare covers of different colors.

[0028] Furthermore, the first protrusion 13 is located above the second protrusion 14. Since the inward end of the mounting part 21 abuts against the light-emitting surface 41, the protrusion length of the first protrusion 13, which is set to abut against the upper outer side of the mounting part 21, is longer. It limits the mounting part 21 from both ends and opposite sides. At the same time, the second protrusion 14 supports the mounting part 21 at the lower outer side of the mounting part 21, thereby improving the fixing effect of the anti-glare cover 2 on the lens 4.

[0029] Furthermore, the arc-shaped anti-glare portion 22 creates a clearance space 24, within which the first protrusion 13 is located. That is, the first protrusion 13 is located between the anti-glare portion 22 and the mounting portion 21, which facilitates the installation of the anti-glare cover 2 and the limiting of the mounting portion 21 by the first protrusion 13.

[0030] Furthermore, the lamp housing 1 is configured as a profile, which can be manufactured by extrusion process to achieve mass production. At the same time, the cross-sectional shape of the profile can be formed during manufacturing, that is, the mounting cavity 11, fixing groove 12, first protrusion 13 and second protrusion 14 are integrally formed without additional cutting or welding processes, which simplifies the production process and effectively reduces production costs.

[0031] As attached Figure 3 To be continued Figure 6As shown, in some embodiments, the anti-glare cover 2 further includes a positioning part 23, which is disposed on the mounting part 21 and located on the side abutting against the lens 4. The side of the lens 4 abuts against the positioning part 23. The positioning part 23 not only guides the anti-glare cover 2 during insertion into the fixing slot 12, preventing the anti-glare cover 2 from shifting and ensuring that it can be inserted accurately and smoothly; but also, after the anti-glare cover 2 is installed, the abutment between the positioning part 23 and the side of the lens 4 further restricts the horizontal displacement of the lens 4, preventing the lens 4 from becoming loose due to external vibrations or other factors, thereby ensuring that the lens 4 is always in the preset optical position, ensuring the stability and accuracy of the lighting light, and improving the overall optical performance of the lamp; and the setting of the positioning part 23 makes the anti-glare cover 2 and the lens 4 form a tighter fit, reducing the gap between them, preventing dust and other impurities from entering and affecting the lighting effect, and extending the service life of the lamp.

[0032] Furthermore, the inner wall of the mounting cavity 11 is provided with a clearance groove 15 corresponding to the position of the positioning part 23 to avoid contact between the positioning part 23 and the mounting cavity 11, prevent frictional resistance during assembly, and facilitate the insertion of the anti-glare cover 2 into the fixing groove 12 along the length direction of the lamp housing 1.

[0033] Furthermore, the anti-glare cover 2 has an overall structure similar to the number "4", and is fitted and installed between the lamp housing 1 and the lens 4, so that the anti-glare cover 2 provides maximum stability while meeting the functions of protection and anti-glare.

[0034] As attached Figure 1 Appendix Figure 2 and attached Figure 8 As shown, in some embodiments, the light-emitting surface 41 of the lens 4 is a flat surface. In the prior art, the lens 4 has a dividing component such as a grid in the middle. The flat light-emitting surface 41 of this application can maintain a continuous light-emitting surface, prevent shadows from being cast on the illuminated object, improve the uniformity of the illumination light, and also solve the problem of difficult-to-clean dirt on the lens 4.

[0035] As attached Figure 3 To be continued Figure 4 and attached Figure 7 Appendix Figure 8As shown, in some embodiments, the lens 4 and the reflector 3 are connected by a snap-fit ​​mechanism. The snap-fit ​​mechanism includes a latch 51 on one of the lens 4 and the reflector 3, and a latch protrusion 52 on the other. During assembly, the latch protrusion 52 can be aligned with the opening of the latch 51. By applying a certain external force, the latch protrusion 52 is elastically deformed and snapped into the latch 51, thus achieving a quick connection and fixation between the lens 4 and the reflector 3 without the need for additional screws or other fasteners. This not only simplifies the assembly process and reduces production time and cost, but also ensures the stability of the connection structure. Furthermore, it facilitates subsequent disassembly and maintenance. When cleaning or replacing the lens 4 or the reflector 3 is required, only a reverse force needs to be applied to separate them, improving efficiency.

[0036] As attached Figure 3 To be continued Figure 4 and attached Figure 9 As shown, in some embodiments, the reflector assembly further includes at least two reflector supports 6, which are connected to the end of the reflector 3 furthest from the lens 4. Compared to existing solutions where the reflector supports are a single piece, this application segments the reflector supports 6 and sets them in at least two segments, saving on molds and product weight, and reducing costs. Simultaneously, the independent arrangement of multiple reflector supports 6 allows for better adaptation to reflectors 3 of different sizes or curvatures, enhancing the support stability of the reflector 3 and preventing deformation of the reflector due to uneven stress on a single long support, thus ensuring that the optical reflection effect of the reflector is not affected. When installing or replacing the reflector, operation can be performed on a single reflector support 6 without the need for complete disassembly, further improving maintenance convenience.

[0037] Furthermore, the reflector cup bracket 6 and the reflector cup 3 are also connected by a snap-fit ​​mechanism, which further improves the convenience of maintenance.

[0038] As attached Figure 10 As shown in the figure, this application embodiment also provides a linear light, which adopts the technical solution described below: The system includes a light source 7 and the reflector assembly. The light source 7 is positioned at the end of the reflector 3 furthest from the lens 4 and is located within the mounting cavity 11. During installation, the anti-glare cover 2 can be inserted into the fixing groove 12 along the length of the lamp housing 1. Therefore, only the assembly tolerances of the reflector 3 and the lens 4 need to be controlled. The anti-glare cover 2 securely clamps the reflector 3 and the lens 4 through insertion. The installation of the anti-glare cover 2 and the lamp housing 1 is simple, convenient, and quick, significantly improving production efficiency.

[0039] During installation, bolts are used to simultaneously fix the reflector cup bracket 6 and the light source 7 to the bottom wall of the mounting cavity 11. Then, the reflector cup 3 and the lens 4 are fastened together using the buckle. Next, the reflector cup 3 with the lens 4 connected to it is fastened to the reflector cup bracket 6. After that, the anti-glare cover 2 is inserted into the fixing groove 12 along the length of the lamp housing 1. Finally, the decorative piece 8 is fixed to both ends of the lamp housing 1 with bolts to complete the assembly. Disassembly is the reverse process.

[0040] Obviously, the embodiments described above are only some embodiments of this application, not all embodiments. The accompanying drawings show preferred embodiments of this application, but do not limit the patent scope of this application. This application can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this application.
