Abstract
The invention provides a novel full inorganic perovskite quantum dot silica gel lens and is applied to LED light distribution. The novel full inorganic perovskite quantum dot silica gel lens comprises a lens body, wherein an emission surface of the lens body is in a two-semi-circular or semi-elliptical double-ball butterfly shape, a groove is on the surface, a bottom portion of the lens body is provided with a conic diffusion hole, a lower end of the conic diffusion hole is provided with a support equipped with an LED chip, the lens body is formed through solidification of silica gel fixed with quantum dot powder, and the quantum dot powder is prepared by a full inorganic perovskite material. The invention further provides a preparation method of the novel full inorganic perovskite quantum dot silica gel lens. The novel full inorganic perovskite quantum dot silica gel lens is advantaged in that wider color gamut and high light emission efficiency are realized.
