Technical Field

[0001] The utility model belongs to the technical field of street lamps, in particular to LED street lamp lens lighting, and specifically relates to an anti-glare LED lens module. Background Art

[0002] As a new type of light source, LED has many advantages such as long life, high conversion efficiency, and fast startup speed, and is widely used. With the rapid development of road traffic construction in my country, the construction scale and number of highway tunnels are also increasing. As a result, tunnel lighting has also encountered urgent problems such as energy saving and safety. With the increasing maturity of LED light source technology, the domestic lighting industry has also carried out research and application practice on the application of LED in highway tunnel lighting. Therefore, combining advanced control methods in tunnel lighting and using a new generation of light sources with high light efficiency, good stability, and long life will become a demand and trend. However, if the existing LED lamps are directly used for tunnel lighting, despite the advantages of high light transmittance and low maintenance cost, they cannot avoid the disadvantages caused by glare. For drivers, glare will directly affect the driver's ability to judge the surrounding environment and easily increase driving risks.

[0003] The existing utility model CN202120650570.0 is a tunnel street lamp, which adopts a U-shaped mounting bracket as a fastener during installation, so that the tunnel lamp can adjust the illumination angle of the lamp body through the fastener, so that the lighting in the entire tunnel becomes uniform and controllable; however, this structure requires manual adjustment, which increases the cost during installation and the weight of the tunnel lamp itself, and still cannot effectively solve the irritation to the eyes caused by the tunnel lamp itself. Utility Model Content

[0004] The utility model aims to solve the problems in the above-mentioned background technology, and for this purpose provides an LED street lamp lens module.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0007] Preferably, the lens is a convex lens, and the convex apex is biased toward a side of the lens close to the electronic device accommodating cavity.

[0008] Preferably, the arc-shaped optical surface is a convex lens, and the convex vertex is biased toward a side of the arc-shaped optical surface away from the electronic device accommodating cavity.

[0009] Preferably, the arc-shaped optical surface is provided with a plurality of frosted bands and light-transmitting bands spaced apart from each other.

[0010] Preferably, a screw hole with an edge boss is provided at the center of the lens array plane.

[0011] Preferably, the module body is integrally mounted on an aluminum substrate.

[0012] Preferably, a decorative plate positioning column is also provided on the lower surface of the module body.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. By rationally arranging the positions of LEDs and lenses, the uniformity of lighting can be improved. The electronic accommodation space can provide sealed space for unpackaged power supplies, lightning protection, single-lamp controllers, etc., saving metal materials and making it more practical.

[0015] 2. By staggering the internal lens and the vertices of the external arc-shaped optical surface, the light path of the LED lamp is dispersed in all directions, achieving the effect of multiple light distribution. At the same time, the frosted belt and the light-transmitting belt of the external arc-shaped optical surface are arranged at intervals, making the LED light softer, avoiding the formation of uneven light spots and direct exposure to human eyes.

[0029] like Figure 1 — Fig. 9 As shown, an anti-glare LED lens module comprises a module body 1, wherein a sealing groove 2 is provided at the edge of the lower surface of the module body 1; a convex electronic device accommodating cavity 3 and a concave lens array plane 4 are provided on the upper surface of the module body 1, and a plurality of lenses 5 are provided on the lens array plane 4, wherein the plurality of lenses 5 are distributed in a matrix to form a lens group, and the lens array plane 4 in a concave state can block stray light near an angle of 90° through the edge, especially the light reflected through the edge of the light surface will not have brightness attenuation, but can effectively avoid the direct angle between the human eye and prevent glare; an arc-shaped optical surface 6 is provided on the outside of the lens 5; a circle of screw accommodating cavities 7 for fastening the aluminum substrate are provided around the module body 1, and when the screws pass through the screw accommodating cavity 7 for fastening the aluminum substrate to lock the module body 1 and the aluminum substrate, the sealing groove 2 can reduce the deformation of the lens 5 itself through its own deformation to ensure the uniformity of the lighting.

[0030] The lens 5 is a convex lens, and the convex vertex is biased toward the side of the lens 5 close to the electronic device accommodating cavity 3. The arc-shaped optical surface 6 is a convex lens, and the convex vertex is biased toward the side of the arc-shaped optical surface 6 away from the electronic device accommodating cavity 3. The surface of the arc-shaped optical surface 6 is provided with a plurality of mutually spaced frosted strips 601 and light-transmitting strips 602; Figure 7-Figure 8 ,in Figure 7 for Figure 5 A partial enlarged view shows that the lens 5 and the curved optical surface 6 have different shapes, and their vertices are staggered, which effectively achieves the effect of multiple light distribution. At the same time, the frosted belt 601 on the surface of the curved optical surface 6 forms a diffuse reflection of the light, and the light-transmitting belt 602 ensures that the original illumination is not weakened, avoiding the formation of light spots at fixed positions and the direct light entering the human eye.

[0031] In order to control the gap between the lens and the aluminum substrate, a screw hole 8 with an edge boss is provided at the center of the lens array plane 4, which can be adjusted by tightening and loosening the screw.
