Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.

With reference to fig. 1 to 3, the utility model discloses a join in marriage anti-dazzle wall lens of washing of anti-dazzle cover, include to be equipped with an anti-dazzle cover 2 in a lens 1's the outside, the mountable of anti-dazzle cover 2 is on a lamp shade 3, and lens 1 is located the distance department at anti-dazzle cover 2 rear, for example makes lens be located anti-dazzle cover rear 20mm left and right sides department. The back of the lens 1 is connected to a lamp panel 4, and a light source (not shown) on the lamp panel 4 is located in the middle of the groove portion of the lens 1. The antiglare cover 2 has a light inlet 21 and a light outlet 22 formed at both ends thereof, a side 23 of a cone is formed between the light inlet 21 and the light outlet 22, and the light inlet 21 corresponds to the upper part of the light-emitting surface of the lens 1.

For the lens, as shown in fig. 4 to 6, the lens 1 includes a lens body 10, a light emitting surface 11 is formed on the front surface of the lens body, a groove 12 is formed on the back surface of the lens body and is recessed inwards, and the light source is located at the bottom of the groove 12. The periphery of the front surface of the lens body 10 forms a circular edge 100, at least two clamping grooves 101 can be arranged on the circular edge 100, and clamping blocks 102 are arranged in the clamping grooves, so that the lens can be conveniently installed and fixed. Specifically, the light emitting surface 11 at the upper end of the lens is convexly provided with a front compound eye structure consisting of a plurality of beads, the compound eye bead surface can play a role in mixing light, and light spots coming out of the front compound eye structure are uniform and have no yellow spots. In the utility model, go out plain noodles 11 including the center district 11 that is located the center and the outer loop district 12 that is located the center outside, make center district 111 form the compound eyeball face of Fermat spiral, outer loop district 112 forms the compound eyeball face of hexagon, and the mixed light effect is better, and is more novel in the outward appearance.

Further, in the light emitting surface, the central area 111 forms a first free-form surface protruding upward, the outer ring area 112 gradually recedes inward from the outer edge to the central area, and the outer ring area 112 forms a second arc surface.
