Description
Technical Field
[0001] This utility model relates to the technical field of recessed lighting, and in particular to a wall washer recessed lighting fixture with a heat dissipation lamp body. Background Technology
[0002] In the field of lighting equipment technology, recessed lights are widely used in indoor and outdoor decorative lighting due to their unique lighting effects and installation methods. With the popularization of LED light sources, their advantages of high efficiency and energy saving are significant. However, LED light sources generate a lot of heat when working. If heat cannot be dissipated in a timely and effective manner, it will affect the lifespan and luminous efficiency of the LED light source. Therefore, the heat dissipation performance of the lamp body has become a key factor affecting the quality of recessed lights.
[0003] In the existing technology, there are integrated die-cast lamp bodies on the market, which have a heat sink structure on the top. The heat sink structure cooperates with the heat sink block and makes the heat sink block contact the light source inside the lamp body to achieve heat dissipation. However, the heat sink block is mostly an independent component, which usually needs to be fixed to the lamp body by welding, screw connection or other methods to contact the heat sink block. This structure method increases the processing steps and assembly difficulty, and also increases the material cost. In addition, welding or screw connection methods are prone to poor contact between the heat sink block and the lamp body, thus affecting the heat dissipation effect, which urgently needs to be solved.

[0040] The following is a reference appendix. Figure 1 To be continued Figure 7 This application describes a wall washer recessed light with a heat dissipation lamp body.
[0041] like Figure 1 and Figure 2As shown, a wall washer recessed lighting fixture with a heat dissipation lamp body includes a lamp body 1. The lamp body 1 is open at both ends and hollow. Several heat dissipation fins 2 are arranged along the cross-sectional direction on the upper part of the lamp body 1. Each heat dissipation fin 2 has an inlay hole 3. A heat dissipation block 4, a mounting plate 5, and a polarizing reflector 6 are arranged sequentially from top to bottom inside the lamp body 1. The heat dissipation block 4 is fitted between the heat dissipation fins 2 and the lamp body 1 through the inlay hole 3. The mounting plate 5 has a light transmission hole 7, and a light source 8 for emitting light is provided in the light transmission hole 7. The light source 8 abuts against the bottom of the heat dissipation block 4. The polarizing reflector 6 is fixedly installed at the open end of the bottom of the lamp body 1. Specifically, the recessed light constructs a heat conduction path in the order of light source 8, heat sink 4, lamp body 1, and heat sink 2 to achieve heat dissipation. The light emitted by the light source 8 is reflected by the polarizing reflector 6 to achieve wall washing and downlighting functions. The heat sink 4 is fitted between the heat sink 2 and the lamp body 1 through the mounting hole 3 to form a gapless heat conduction path. Compared with the traditional screw or welded structure, it can reduce thermal resistance and ensure that the heat generated by the light source 8 can be conducted to the heat sink 2 in time through the heat sink 4. Furthermore, the LED light source 8 is fixed by the mounting plate 5, which can avoid the risk of heat dissipation failure due to loosening of the light source 8.
[0042] Preferably, the lamp body 1 and several heat sinks 2 are integrally manufactured by die casting. The integral die-cast lamp body 1 can eliminate the gap between the heat sinks 2 and the lamp body 1, improve the heat conduction effect, and use the integral die-cast part as the fitting carrier of the heat sink 4, which can save assembly process.
[0043] like Figure 2 and Figure 3 As shown, in this embodiment, the polarizing reflector 6 includes a direct light area 61 and a polarizing area 62. The polarizing area 62 is located at the end of the direct light area 61 and is connected to the direct light area 61, and extends along the cross-sectional direction of the direct light area 61. Specifically, after the light source 8 enters the interior of the polarizing reflector 6, the central light is projected through the direct light area 61 to achieve the function of wall washing, and the edge light diffuses into the polarizing area 62 within the direct light area 61 and is emitted from the polarizing area 62 to achieve the function of downlighting. This is suitable for the working conditions of wall washing downlighting recessed lights.
[0044] like Figure 2 As shown, preferably, the mounting plate 5 has a positioning groove 9 at the bottom and the polarizing reflector cup 6 has a positioning plate 10 at the top. The positioning groove 9 and the positioning plate 10 are inserted and matched. Under the action of the insertion and matching of the positioning groove 9 and the positioning plate 10, the polarizing reflector cup 6 can be quickly and accurately assembled.
[0045] Preferably, the mounting plate 5 has mounting screw holes 11. The mounting plate 5 is fixedly installed inside the lamp body 1 by means of a threaded connection through the mounting screw holes 11, so that the light source 8 abuts against the bottom of the heat sink 4. By setting the mounting screw holes 11, the threaded connection can pass through the installation position, and the adjustable mechanical connection of the threaded connection can ensure the contact pressure between the light source 8 and the heat sink 4, and ensure the stability of heat dissipation.
[0046] like Figure 2 and Figure 3 As shown, in order to provide support for the polarizing reflector, in one embodiment, the wall washer recessed lighting lamp with heat dissipation lamp body also includes a face ring 12 for supporting the polarizing reflector cup 6. A retaining spring 13 is installed between the face ring 12 and the inside of the lamp body 1. The face ring 12 is fastened to the inside of the lamp body 1 by the retaining spring 13 to complete the installation of the recessed lighting lamp. Compared with the traditional threaded connection, it can save the installation process.
[0047] like Figure 5 , Figure 6 and Figure 7 As shown, in order to be suitable for the working conditions of frameless recessed lighting, in one embodiment, the wall washer recessed lighting with heat dissipation lamp body also includes a pre-embedded frame 14. A slider 15 is provided on the inner side of the pre-embedded frame 14. An access groove 16 is provided vertically at the end of the lamp body 1. The first end of the access groove 16 is open and the last end is connected to a sliding groove 17 along the circumference of the lamp body 1. The last end of the sliding groove 17 is connected to a positioning groove 18 along the vertical direction. The slider 15 slides and engages with the access groove 16, the sliding groove 17 and the positioning groove 18. The access groove 16, the sliding groove 17 and the positioning groove 18 on the outer side of the lamp body 1 form a concave fixing path. With the access and sliding of the slider 15 in the pre-embedded frame 14, the limiting installation between the pre-embedded frame 14 and the lamp body 1 can be completed, which is suitable for the working conditions of frameless recessed lighting.
[0048] Furthermore, the embedded frame 14 includes an outer bracket 141 and an inner frame 142. The outer bracket 141 has a vertically oriented strip-shaped adjustment hole 143, and the inner frame 142 has a threaded groove 144 corresponding to the position of the strip-shaped adjustment hole 143. An adjusting screw 145 for threaded engagement with the threaded groove 144 is inserted into the strip-shaped adjustment hole 143. Before installing the embedded frame 14 on the wall or ceiling, the workers can assemble the outer bracket 141 and the inner frame 142 under the threaded engagement of the threaded groove 144 and the adjusting screw 145. At the same time, the distance of the outer bracket 141 offset relative to the inner frame 142 can be adjusted by adjusting the vertical position of the adjusting screw 145 on the strip-shaped adjustment hole 143. Since the outer bracket 141 is installed inside the wall or ceiling, the distance of the lamp body 1 relative to the wall or the height relative to the ceiling can be adjusted.
[0049] like Figure 1 and Figure 3As shown, in order to be suitable for the use of recessed lights with edges, in one embodiment, I-shaped holes 19 are provided on both sides of the lamp body 1. A torsion spring 20 is fixedly connected in the I-shaped hole 19. The lamp body 1 is installed on the wall or ceiling through the end of the torsion spring 20 away from the lamp body 1. In use, the worker can embed the recessed light in the wall or ceiling with reserved space, and then fix it by the end of the torsion spring 20 away from the lamp body 1 to complete the installation of the recessed light. This is suitable for the use of recessed lights with edges.
[0050] It should be noted that the actual assembly process of this recessed lamp structure is as follows: the light source 8 is wired, and the light source 8 is fixed inside the lamp body 1 by the mounting plate 5 and screws. The polarizing reflector 6 is fixed on the mounting plate 5 by plugging (the positioning groove 9 and the positioning plate 10 cooperate). The face ring 12 is fixed to the inside of the lamp body 1 by the snap ring 13. The wire is fixed on the lamp body 1 by bolts and rubber rings.
[0051] When used as a recessed light structure, the torsion spring 20 is assembled on the I-shaped hole 19 of the light body 1. After the recessed light is embedded in the wall or ceiling, it is fixed by the end of the torsion spring 20 away from the light body 1, thus completing the installation of the recessed light.
[0052] When used as a frameless recessed light structure, the pre-embedded frame 14 is first installed into the wall or ceiling. Then, the light body 1 is connected and slid with the slider 15 in the pre-embedded frame 14 through the access groove 16, sliding groove 17 and positioning groove 18 on the outside of the light body 1, respectively, to complete the limiting installation between the pre-embedded frame 14 and the light body 1, thereby completing the installation of the recessed light.
[0053] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of this application.
