Embodiment Construction

[0027] Such as Figure 1 to Figure 12 Shown is a kind of LED street lamp lens of the present invention, as figure 1 , figure 2 , image 3 As shown, it includes a lens body 10 and an accommodating cavity 20, wherein the lens body 10 has a top 11, a bottom 12 and side surfaces 13, wherein the top 11 is provided with a first exit surface 111 and two second exit surfaces 112 , the first exit surface 111 surrounds the central axis 110 of the lens body 10, and the two second exit surfaces 112 are arranged in the middle of the first exit surface 111 with the central axis 110 of the lens body 10 as a line of symmetry The side surface 13 is provided with a mesh reflective surface 131, so that the light irradiated on the mesh reflective surface 131 is reflected to the first exit surface 111 and the two second exit surfaces 112 via the mesh emission surface 131, The lens body 10 is then ejected.

[0028] The accommodating cavity 20 is arranged on the bottom 12 of the lens body 10 co...

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.

Description

technical field [0001] The invention relates to an optical lens, more specifically to an LED street lamp lens. Background technique [0002] Because LED lights have the advantages of energy saving, easy control, long life, and low maintenance costs, LED lights have gradually replaced traditional lamps, and LED light sources are more and more widely used as street lights. , in order to meet the requirements of road lighting, it is necessary to redistribute the light on the basis of fully improving the utilization rate of light energy, because road lighting requires that the light should be effectively irradiated on the road to form a spot that matches the road surface, otherwise, it will not only waste electric energy, but also It will cause light pollution to the surrounding environment. [0003] At present, the main light distribution form of common LED street lamps is to arch or recess the LED light-emitting module. Although this light distribution form can distribute lig...
