DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, and not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the present application.

[0026] As Figures 1 to 7 The optical accessory module of the invention is shown in the drawing, which comprises a lens 1, the front and rear sides of the bottom of the lens 1 are respectively covered with an anti-glare ring 2 and a reflector 3, the top of the lens 1 is provided with an entrance hole 101, and the bottom of the lens 1 is provided with two or more light-emitting inclined surfaces in opposite directions from front to back. The reflector 3 is gradually smaller from top to bottom, and the reflector 3 is inclined downward from back to front, and the inner wall of the reflector 3 is provided with a micro-structure reflecting surface 301. The light source light enters the lens 1, a part of the light is incident through the front side of the entrance hole 101, the light is reflected on the front side wall of the lens 1, and then is refracted out of the light-emitting inclined surface. Due to the inclination of the light-emitting inclined surface, the light is mainly irradiated on the lower part of the wall, and the corresponding light spot is collectively referred to as the lower wall light spot. Another part of the light is incident through the bottom side of the entrance hole 101, and then is refracted out of the light-emitting inclined surface. Due to the inclination of the light-emitting inclined surface, the light is mainly irradiated on the middle part of the wall, and the corresponding light spot is collectively referred to as the middle wall light spot. A part of the light is incident through the rear side of the entrance hole 101, the light is reflected on the rear side wall of the lens 1, and then is refracted out of the light-emitting inclined surface. The light is reflected by the micro-structure reflecting surface 301, and is mainly irradiated on the upper part of the wall, and the corresponding light spot is collectively referred to as the upper wall light spot. The width of the upper, middle and lower wall light spots is kept consistent, the wall washing light spot presents a rectangle, the illumination is comprehensive, the illumination is uniform, the structure is simple, the heat dissipation is good, the light waste is small, the light efficiency is high, and the structure is general with the conventional lamps on the market.

[0027] As a specific embodiment, the bottom of the lens 1 is sequentially provided with a first light-emitting inclined surface 102, a second light-emitting inclined surface 103, a third light-emitting inclined surface 104 and a fourth light-emitting inclined surface 105 from front to back. The light source light enters the lens 1, a part of the light is incident after the side wall surface of the lens light inlet hole 101, and then the light is reflected at the outer side wall of the lens 1 and then refracted and emitted from the first light-emitting inclined surface 102, the second light-emitting inclined surface 103, the third light-emitting inclined surface 104 and the fourth light-emitting inclined surface 105. Because the inclination directions of the light-emitting inclined surfaces are different, at this time, the light is forced to be divided into two parts, and the light emitted from the first light-emitting inclined surface 102 and the second light-emitting inclined surface 103 in the same direction is more, which directly irradiates on the wall and mainly irradiates on the lower part of the wall, so the corresponding light spot is collectively referred to as the lower wall light spot. Another part of the light, which accounts for a small proportion, is mainly refracted from the third light-emitting inclined surface 104 and the fourth light-emitting inclined surface 105, and then reflected by the reflecting microstructure surface 301 of the reflector 3, thereby irradiating on the uppermost part of the wall, and the corresponding light spot is collectively referred to as the upper wall light spot. Another part of the light is incident through the bottom of the light inlet hole 101, and then refracted from the first light-emitting inclined surface 102 and the second light-emitting inclined surface 103 of the lens 1, and then directly irradiates on the middle of the wall, which is collectively referred to as the middle wall light spot. The wall washing light spot presents a rectangular shape, realizes the gradual change of the upper wall light spot, and keeps consistent with the width of the lower and middle light spots, so that the illumination is comprehensive and uniform, the light waste is small, and the light efficiency is high.

[0028] The outer side of the lens 1 is provided with a total reflection surface 106, and the bottom of the light inlet hole 101 is provided with a bottom incident curved surface 107. By adjusting the shape and size of the bottom incident curved surface 107, the range and degree of gradual change of the middle wall light spot can be controlled. The side wall of the light inlet hole 101 is provided with a side incident arc surface 108, which realizes comprehensive reflection and refraction of the light, improves the utilization rate of the light, and realizes uniform illumination, small light waste and high light efficiency.

[0029] The bottom of the lens 1 is provided with a flange 109, the top of the reflector 3 is provided with a reflector mounting platform 302 corresponding to the flange 109, and the top of the anti-dazzle ring 2 is provided with an anti-dazzle ring mounting platform 201 corresponding to the flange 109, so as to facilitate the quick and stable positioning and installation of the lens 1.

[0030] The top of the reflector 3 is provided with a first clamping hook 303, the bottom of the lens 1 is provided with a first clamping groove corresponding to the first clamping hook 303, the top of the anti-dazzle ring 2 is provided with a second clamping hook 202, and the bottom of the lens 1 is provided with a second clamping groove 110 corresponding to the second clamping hook 202, which is beneficial to the quick clamping and installation of the lens 1 to the top of the reflector 3 and the anti-dazzle ring 2.

[0031] The inner wall of the anti-glare ring 2 is provided with an anti-glare curved surface 203, and the rear side of the anti-glare ring 2 is provided with an anti-glare straight plate 204 for connecting the reflector 3, thereby improving the reflection efficiency of the anti-glare ring 2 and the uniformity of light emission.

[0032] The top of the front side of the reflector 3 is provided with a third clamping groove 304, and the top of the front side of the anti-glare ring 2 is provided with a third clamping hook 206 corresponding to the third clamping groove 304.

[0033] The light-emitting inclined surface is provided with a micro-structured light-emitting surface, thereby improving the uniformity of the emitted light.

[0034] The top of the lens 1 is provided with a light source support 4, and the light source support 4 is provided with an LED light source 5 for emitting light to the light inlet hole 101, thereby facilitating stable incidence of light.

[0035] The bottom cover of the anti-glare ring 2 is provided with a light-transmitting dustproof sheet 6, thereby protecting the inner side of the reflector 3 and the anti-glare ring 2 from being contaminated and ensuring working performance.

[0036] The wall washing principle is as follows:

[0037] The entire wall washing light spot is formed by splicing three light spots, which are divided into an upper wall light spot, a middle wall light spot and a lower wall light spot.

[0038] The shape principle of the wall light spot is as follows:

[0039] According to the geometric principle, when the length of one side of a triangle is fixed, the higher the height, the smaller the angle of the corresponding angle of the side. Therefore, applied to the wall washing of the lamp, in order to make the wall washing light spot present as a rectangle, it is necessary to ensure that the angle of each position of the light spot is in a gradual state, and the angle of the light spot above the wall is the largest, and gradually decreases. By adjusting the shape of the TIR surface of the lens, the upper and lower contour lines are not circular, so that the light spot below the wall presents a size gradient. By adjusting the bottom surface of the light inlet hole of the lens to be a free surface, the light spot in the middle of the wall is realized to be gradually changed, and the width is consistent with the light spot below. By adjusting the reflecting surface of the reflector to be a free surface and the microstructure characteristics, the light spot above the wall is realized to be gradually changed, and the width is consistent with the light spot below and in the middle.

[0040] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
