Abstract
The invention provides an LED street lamp lens. After an LED street lamp is provided with the lens, light rays enter from a light incidence plane; when the light rays pass through a reticular reflection plane, since the reticular reflection plane is formed by connecting a plurality of small curved surfaces, after the light rays irradiate the small curved surfaces, the small curved surfaces reflect the light rays, which are irradiated from different angles, to form a plurality of secondary small curved surface light sources at different light emitting angles; the light rays of the secondary light sources formed by the small curved surfaces are mutually staggered, so that the illumination of light spots becomes more uniform; the colors of the light spots are blended due to the staggered light rays from the small curved surfaces, thus the color difference is reduced; and after the light rays are condensed by the reticular reflection plane and refracted out of the two second emergence planes, the distribution of the light rays is controlled, so that the light spots are rectangular, thereby fully utilizing the light emitted from the light source. The LED street lamp with the lens has the advantages of uniform illumination and uniform light color in the effective illumination region, and is especially suitable for lighting on roads and in tunnels.
