Abstract
A ray homogenization structure of LED is provided, which comprises a LED and a circuit board. The LED is fixedly arranged on the circuit board; the circuit board is provided with an inner lens and an outer lens. The inner lens encloses the outside of the LED, while the outer lens encloses the outside of the inner lens. The outside surface of the inner lens is provided with a plurality of prisms, while the inside surface of the outer lens is provided with a plurality of non-light tight cylinders. The prism axes are in parallel with each other; the axes of the non-light tight cylinders are in parallel with each other, and the axial directions of the prisms and the non-light tight cylinders are also in parallel with each other. The light emitted from the LED passes the lens to generate perfect reflection and then is emitted at specific angle after changing the direction; then the light is scattered by the non-light tight cylinders on the inside surface of the outer lens to form a light ray with homogenized lighting intensity in the given axis direction from 0 degree to 180 degree, which can realize the application for partial signal lamp modulators under different requirements of the lighting intensity on some points from up to down or from left to right, with homogenized lighting in directional distribution.
