Abstract

The invention discloses a total internal reflection lens with a compound eye, which comprises a lens body whose size gradually decreases from top to bottom. The bottom of the lens body is provided with an accommodating cavity for installing LEDs, and the accommodating cavity is arranged on the lens body. In the middle of the bottom of the body, red LEDs, green LEDs, blue LEDs and white LEDs are installed in the cavity, and the top of the lens body is provided with a compound eye for emitting light and a light-shielding part for preventing light from being directly emitted through the compound eye. The light-shielding part is arranged in the middle of the top of the lens body, and a transparent bead having a refractive index different from that of the lens body is arranged inside the lens body. The light emitted by LEDs of different colors in the accommodating cavity is firstly reflected and refracted inside the lens body through transparent beads to mix light, and then when emitted through the compound eye, the light is mixed twice through the compound eye, which greatly improves the mixing effect. The light effect makes the light more uniform.

Description

technical field [0001] The invention relates to an LED lens, in particular to a total internal reflection lens with compound eyes. 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] In order to solve the above problems, the object of the present invention is to provide a total internal reflection lens with compound eyes. [0004] The technical solution adopted by the present invention to solve the problem is: a total internal reflection lens with compound eyes, 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 LED. Cavity, the accommodating cavity is set in...
