The dedicated lamps used for polarized wall washing are usually not conventional downlights, but are of specific size or shape, and their versatility is poor. In today's market with diversified demands and more complete functional requirements and needs for lamps, the number of conventional downlights has reached, the output is high, and the supporting facilities are relatively mature.

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0016] refer to Figure 1-2 As shown, a downlight polarized wall-washing auxiliary component, a downlight polarized wall-washing auxiliary component, comprises a heat dissipation lamp holder 7, a light source 6 is arranged inside the heat dissipation lamp holder 7, an optical lens 4 is fixedly mounted above the light source 6; a light-shielding front ring 1 is mounted on the top of the heat dissipation lamp holder 7, a reflective cup 2 is clamped and assembled in the light-shielding front ring 1, and a polarizer 3 is connected to the bottom of the reflective cup 2;

[0017] The lower end surface of the polarizer 3 is provided with polarizing teeth 31, and the upper end surface is provided with polarizing stripes 32;

[0018] Furthermore, the optical lens 4 is fixed on the light source board 71 inside the heat dissipation lamp frame 7 through the lens bracket 5;

[0019] Furthermore, the reflective cup 2 is a quarter-spherical cup; the inner wall of the reflective cup 2 is a curved reflective wall 21;

[0020] Furthermore, the light-shielding front ring 1 is divided into a light-shielding ring 12 and a light-passing ring 11; the light-shielding ring 12 is located above the reflector cup 2; and the surface of the light-shielding ring 12 is flush with the top edge of the heat dissipation lamp holder 7;

[0021] Furthermore, the heat dissipation lamp holder 7 is made of a thermally conductive alloy metal material;

[0022] In this embodiment, the size and external shape of the heat dissipation lamp holder 7 are the same as those of conventional heat dissipation lamp holders.

[0023] During the specific implementation of the utility model, the light source 6 emits light, and the light first passes through the polarizer 3. The lower end surface of the polarizer 3 is a polarizer tooth 31. The polarizer tooth 31 deflects the light so that part of the light is deflected to the cavity wall, and the upper end surface of the polarizer 3 is provided with a polarizer stripe 32. The polarizer stripe 32 can make the longitudinal light of the lamp more widely dispersed, thereby ensuring the width of the light spot and avoiding too narrow spacing between the lamps.

[0024] After the light is polarized for the first time, it passes through the additional reflector cup 2 to reflect the remaining light onto the wall of the lighting surface, avoiding light waste and light leakage; finally, the remaining stray light is shielded by the top shading front ring 1; and the end of the heat dissipation lamp holder 7 is ensured to be flat;

[0025] The utility model has a simple overall structure, and the polarizer is designed on both sides to deflect and expand the light, thereby widening the lighting effect. The reflector cup reflects polarized light, and uses the light source reasonably to avoid waste and light leakage. The light-shielding front ring is then used to block the light source to ensure the neatness and effect of the polarized lighting. The overall cost is low, the structure is improved reasonably, and the existing conventional downlights are fully utilized to avoid waste in production capacity, thereby widening the range of lamp usage scenarios.

[0026] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the scope defined by the spirit of the present invention.
