Description

Technical Field

[0001] This utility model relates to, but is not limited to, the field of lighting fixtures, and particularly to a rear anti-glare wall washer light. Background Technology

[0002] Existing wall washer lights use an LED plus lens light output mode. The light output angle is controlled by the lens, and the required wall washing height is achieved by adjusting the bracket angle in conjunction with the lens light output.

[0003] The existing anti-glare solutions for wall washer lights involve adding anti-glare panels, honeycomb meshes, grilles, etc. to control glare. However, controlling glare through these methods results in long production cycles and excessively high costs.

[0004] In addition, existing wall washer lights emit light at a fixed angle when they leave the factory. If the wall washer ratio requirement is to be met, the angle of the light fixture needs to be adjusted. However, this angle needs to be adjusted and calibrated on site when the light fixture is installed. However, the light emitted by the wall washer light after the angle adjustment may have uneven light spots. Utility Model Content

If the wall washer light needs to meet the wall washing ratio requirements, the sway angle of the light fixture needs to be adjusted. The light emitted by the wall washer light after the sway angle is adjusted may have uneven light spots.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0027] The following is in conjunction with the appendix Figures 1 to 4 To further describe, this utility model discloses a rear anti-glare wall washer light, including a first housing 1 and a second housing 2. The first housing 1 and the second housing 2 are fastened together to form a space for accommodating a light-emitting module. The light-emitting module includes a substrate 3 and an LED light source 4 and a reflector 5 mounted on the substrate 3. The light-emitting end of the LED light source 4 is opposite to the reflective surface 51 of the reflector 5. A diffusion layer 6 is provided at the upper end of the first housing 1 and the second housing 2. The diffusion layer 6 is a diffusion film or a diffusion plate. A light-transmitting glass 7 is provided at the upper end of the diffusion layer 6. The light emitted by the LED light source 4 is reflected by the reflector 5 and then uniformly diffused by the diffusion layer 6. It is then refracted by the light-transmitting glass 7 to achieve an ultra-high wall washer light spot. The light-transmitting glass 7 is ultra-clear glass. In addition, a 25% to 50% screen-printed area 71 is provided on the surface of the light-transmitting glass 7 from right to left. The screen-printed area 71 is black. The black screen-printed area 71 can block some stray light and achieve a rear anti-glare effect.

[0028] In a preferred embodiment, side plates 8 are fixed to both ends of the first housing 1 and the second housing 2 by screws, and the receiving space formed by the first housing 1 and the second housing 2 is protected by the side plates 8 at both ends.

[0029] In a preferred embodiment, one or more light-emitting modules respectively form a first light-emitting group 10 and a second light-emitting group 11. The first light-emitting group 10 and the second light-emitting group 11 are both disposed in the accommodating space formed by the first housing 1 and the second housing 2. The first light-emitting group 10 and the second light-emitting group 11 are separated by a partition plate 9.

[0030] In a preferred embodiment, the substrate 3 is an LED aluminum substrate 3 fixed to the inside of the first housing 1 by screws, and an LED light source 4 and a reflector cup 5 are installed on its side, wherein the lower end of the reflector cup 5 is fixed to the substrate 3 by screws.

[0031] In a preferred embodiment, the reflector cup 5 extends from the lower end of the substrate 3 in an arc shape from left to right to form a semi-arc structure, which forms a semi-enclosed structure for the LED light source 4 mounted on the substrate 3.

[0032] In a preferred embodiment, the LED light source 4 is located on the substrate 3. The light-emitting surface of the LED light source is directly opposite the reflective surface of the reflector cup 5, and the light emitted by the LED light source is reflected by the reflective surface of the reflector cup 5, diffused evenly by the diffusion layer 6, and then illuminated on the wall surface through the light-transmitting glass 7.

[0033] In a preferred embodiment, the lower end of the reflector cup is a mounting plate 52, on which mounting holes 53 are provided, and the upper end of the reflector cup is a reflective surface 51; the reflective surface 51 is a free-form surface, and its four corners are bent inward into the reflective surface 51 to form inward folds 54, and its overall shape is approximately asymmetrical half-spoon shape, which is larger at the top and smaller at the bottom.

[0034] like Figure 4 As shown, when light passes through the freeform surface of reflector cup 5, the trajectory of the light changes, so that the area H of the emitted light on the wall and the distance L between the light fixture and the wall form a fixed wall washing ratio. This ratio can be achieved by designing different surfaces of reflector cup 5 according to the customer's requirements for the wall washing ratio, without the need for on-site angling and without affecting the uniformity of the light spot.

[0035] In a preferred embodiment, the four inner corners 54 form an upper arc edge 55 and a lower arc edge 56 located at the upper and lower ends of the reflective surface 51, as well as a side arc edge 57 located on both sides of the reflective surface 51.

[0036] In a preferred embodiment, the reflective surface 51 is provided with a microscale structure or a textured surface, which can scatter light and produce a more complex and dazzling reflection effect.

[0037] In summary, the first housing 1 and the second housing 2 are fastened together to form a space for accommodating the substrate 3 and the LED light source 4 and reflector 5 mounted on the substrate 3. Combined with the diffusion layer 6 and the light-transmitting glass 7 set above the diffusion layer 6, a simple and compact structure is formed, avoiding the complexity of existing structures and shortening the production cycle. The LED light source 4, together with the free-form reflector 5, refracts the light. When the light passes through the diffusion layer 6, the light becomes soft and uniform. The outermost light-transmitting glass 7 has a 25% to 50% black silkscreen area 71, which can block some stray light and achieve a rear anti-glare effect. In addition, the reflector 51 can be designed into the required curved surface according to the construction site to change the wall washing ratio without angling and without affecting the uniformity of the light spot.
