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
The present invention relates to a kind of ultraviolet LED integral lens.
Background technology
At present, ultraviolet LED lens are all single lens substantially, ultraviolet sense of direction and uniformity poor, and ultraviolet leak outside more, easily injury is produced to user of service; Because ultraviolet leaks outside, in order to reach, desirable effect, need to strengthen power consumption, waste energy, cost is higher.
Summary of the invention
The invention provides a kind of ultraviolet LED integral lens, be intended to solve the sense of direction of existing ultraviolet LED lens middle-ultraviolet lamp and the poor problem of uniformity.
In order to solve above technical problem, the present invention is achieved through the following technical solutions: a kind of ultraviolet LED integral lens, comprises sapphire lens layer, silvered reflective layer; Sapphire lens layer is made up of sapphire frame, large concavees lens, little concavees lens, transition lens and sapphire substrate; Described sapphire frame, large concavees lens, little concavees lens and transition lens are all arranged on sapphire substrate; Described sapphire frame is annular; Large concavees lens and little concavees lens are hemisphere, and described transition lens are 1/4th spheroidals, and the radius ratio of large concavees lens and little concavees lens is 2:1; Described transition lens-ring is around on sapphire scuncheon wall; Little concavees lens form at least one little concavees lens circle, large concavees lens form at least one large concavees lens circle, and what contact with transition lens inner ring is a little concavees lens circle, and described little concavees lens circle and large concavees lens circle interval are arranged; Described silvered reflective layer is arranged on the lateral wall of sapphire frame.
Further, the sapphire frame of described sapphire lens layer, large concavees lens, little concavees lens and transition lens are wholely set; Be convenient to manufacture and cost is low, enhance ultraviolet sense of direction and uniformity.
Further, described transition lens are identical with the radius of large concavees lens; Decrease ultraviolet to leak outside.
Further, the center of described sapphire lens layer is little concavees lens; Enhance ultraviolet sense of direction.
Further, described little concavees lens circle has one, and described large concavees lens circle has one; Ultraviolet sense of direction is stronger.
Compared with prior art advantage of the present invention is: in the present invention, sapphire lens layer is made up of sapphire frame, large concavees lens, little concavees lens, transition lens and sapphire substrate; Silvered reflective layer is arranged on the lateral wall of sapphire frame, and the ultraviolet sense of direction sent is strengthened, and uniformity is better, decreases ultraviolet leaking, ensure that the safety of human body, saved use cost and resource.
