Abstract

The invention provides an ultraviolet LED integrated lens, for the purpose of solving the problems of quite poor sense of directions and quite poor uniformity of ultraviolet rays in a conventional ultraviolet LED lens. The ultraviolet LED integrated lens comprises a sapphire lens layer and a silver-coated reflecting layer. The sapphire lens layer is composed of a sapphire frame, large concave lenses, small concave lenses, transition lenses and a sapphire substrate. The sapphire frame is annular; the large concave lenses and the small concave lenses are both semispherical, the transition lenses are one fourth of balls, and the transition lenses are encircled on the inner side wall of the sapphire frame; and the silver-coated reflecting layer is arranged on the outer side wall of the sapphire frame. According to the invention, the sapphire lens layer is composed of the sapphire frame, the large concave lenses, the small concave lenses, the transition lenses and the sapphire substrate. The silver-coated reflecting layer is arranged on the outer side wall of the sapphire frame, such that the sense of directions of the emitted ultraviolet rays is enhanced, the uniformity is better, the leakage of the ultraviolet rays is reduced, human safety is guaranteed, and the application cost and resources are reduced.

Description

technical field [0001] The invention relates to an ultraviolet LED integrated lens. Background technique [0002] At present, the ultraviolet LED lens is basically a single lens, the sense of direction and uniformity of the ultraviolet rays is poor, and the ultraviolet rays leak more, which is easy to cause harm to the user; due to the ultraviolet leakage, in order to achieve the ideal effect, Need to increase electricity consumption, waste energy, and cost is higher. Contents of the invention [0003] The invention provides an ultraviolet LED integrated lens, aiming to solve the problem of poor directionality and uniformity of ultraviolet rays in the existing ultraviolet LED lens. [0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: a UV LED integrated lens, comprising a sapphire lens layer and a silver-plated reflective layer; the sapphire lens layer is composed of a sapphire frame, a large...
