Abstract

The invention discloses a total internal reflection lens capable of uniform light mixing. The total internal reflection lens comprises a lens body, wherein the size of the lens body is gradually reduced from top to bottom, an accommodating cavity is formed in the bottom of the lens body and is used for installing LEDs, the accommodating cavity is arranged in the right middle of the bottom of the lens body, strip lines are arranged on an inner wall of the accommodating cavity and used for improving a light mixing effect, a red LED, a green LED, a blue LED and a white LED are arranged in the accommodating cavity, scales are arranged on a side surface of the lens body and are used for refracting light rays, a compound eye and a shading part are arranged at the top of the lens body, the compound eye is used for irradiating the light rays, the shading part is used for preventing the light rays from irradiating directly through the compound eye, the shading part is arranged in the right middle of the top of the lens body, and transparent balls are arranged in the lens body and are different from the lens body in refractive index. Light emitted from the LEDs in the accommodating cavity firstly is mixed through the strip lines and is then refracted through the scales for secondary light mixing, and finally, third light mixing is performed by the compound eye to achieve uniform light mixing.

Description

technical field [0001] The invention relates to an LED lens, in particular to a lens with uniform light mixing. Background technique [0002] LED lens is an optical system that is closely connected with LED and can enhance light use efficiency and luminous efficiency. Different lenses can be used to change the light field distribution of LED according to different effects, but traditional lenses generally have uneven light mixing. question. Contents of the invention [0003] To solve the above problems, the object of the present invention is to provide a lens with uniform light mixing. [0004] The technical scheme adopted by the present invention to solve the problem is: a lens with uniform light mixing, including a lens body, the size of the lens body gradually decreases from top to bottom, and the bottom of the lens body is provided with an accommodating cavity for installing LEDs. The cavity is set in the middle of the bottom of the lens body. The inner wall of the c...
