Detailed ways

The utility model is described in further detail below in conjunction with the accompanying drawings.

As shown in Figures 1 to 6, it is a preferred embodiment of the present utility model.

The anti-glare LED lamp includes a lamp housing 1 , an LED light source 3 , a light-transmitting dampening plate 2 , a magnifying glass 4 and a cover 41 .

Wherein, the lamp housing 1 is ring-shaped and has a groove opening downward to form a cavity, and the LED light source 3 is installed in the cavity of the lamp housing 1;

The upper surface of the lamp housing 1 is provided with a plurality of heat dissipation holes 14, so that the heat generated by the LED light source 3 can be dissipated through the heat dissipation holes 14, so that the service life of the anti-glare LED lamp can be improved;

The moistening plate 2 is also annular and adapted to the lamp housing 1, and the moistening plate 2 covers the opening of the groove of the lamp housing 1. Specifically, the lower surface of the lamp housing 1 extends inwardly with an annular convex edge 12 , the moistening plate 2 is clamped on the inner side of the annular flange 12 and fixed relative to the lamp housing 1 .

The LED light source 3 includes an annular light-emitting circuit board 31 installed in the cavity of the lamp housing 1 and a plurality of LED lamp beads 32 arranged on the lower end surface of the light-emitting circuit board 31. The LED lamp beads 32 are connected to the light-emitting circuit board 31 The center of the light-emitting circuit board 31 is radially divergent.
