Abstract

Currently LED as a light source is more and more widely applied, this paper presents an optical system design for LED source array base on a Fresnel lens array on a circular disc and a pair of circular mirrors that can compose of LED light together, forming a small area in the high luminance light source optical system can form a high power source system, this system can solve the heat dissipation problem of LED, and then the beam array are uniform, with no color aberration generated by this optical system. Such light source optical system can be used as the LED light source projector, high power shooting lamp, photography light, and many optical instruments such as super power point light source. The use of optical design software to optimize the design and calculation of optical parameters of circular and spherical mirror, based on beam analysis, realize the ideal LED light source array of a general set of optical system structure, can be used to design the others array light source.
