Efficient waterproof LED optical lens free of dark spots in initial irradiation area and for flood light

Abstract

The invention discloses an efficient waterproof LED optical lens free of dark spots in the initial irradiation area and for a flood light. The efficient waterproof LED optical lens comprises a lens body. The upper surface of the lens body is composed of a face A, a face B, a face C and a face D, wherein the face A is a highlight lens face or a frosted lens face; the face B is a fly eye lens face arranged in a fly eye microstructure array mode and is close to a wall, and the light beam angle of the face B is larger than that of the face A; the face C is a fly eye lens face arranged in a fly eye micro structure array mode; the face D is a grating lens face which is arranged in a transverse array mode and inclines by a certain degree; and the space between the face B and the face C is filled with the face D, and the space between the face A and the face D is filled with the face C. Compared with the prior art, the efficient waterproof LED optical lens is novel and unique in structure, and by using the efficient waterproof LED optical lens to the LED flood light, non-uniform bright and dark areas at the bottom of the irradiated wall are avoided, and the light uniformity is good; and the efficient waterproof LED optical lens has the advantages that the lens is waterproof, yellow spots of the wall are avoided, light loss is little, and the irradiation area is large.

Description

technical field [0001] The invention relates to the field of lens technology, in particular to a high-efficiency wall-washing and waterproof LED optical lens with zero dark spots in the irradiation starting area. Background technique [0002] LED wall washer is also called linear LED flood light, LED line light, etc., and is mainly used for single building, indoor partial lighting, green landscape lighting and billboard lighting. The current LED wall washer lens, because the lens has a beam angle, an included angle, etc., will cause light and dark areas to appear at the bottom of the irradiated wall (that is, the bottom of the low-beam surface), such as figure 1 As shown, the illuminated wall is marked as G, the bright area is marked as F, and the dark area is marked as H. The effect of the bottom of the illuminated wall is uneven, the illumination width is not enough, and the macula is concentrated. How to realize the characteristics of low power, long distance and high un...
