Illumination beam shaping system

摘要

The present invention provides an illumination beam shaping system, which enables the emergent surface of a lighting system of light excitation chips to emit a light beam of uniform illumination brightness. The present invention uses a dividing device, structured from curved lenses arranged in an array, to effect a pre-dividing operation on the total quantity of light from a light excitation chip, after which post-diffusion is carried out to form a light beam with uniform illumination brightness. A plurality of conical light beams in an array are shaped and emerge from an output side, and the bottom portion of each of the conical light beams form an actual optical surface, which act on an optical diffusing component for refraction and diffusion processing, thereby enabling the emergent face of the system to obtain uniform illumination brightness.
