Abstract

A new kind of lenses system is proposed in this paper for LED illuminance, it can improve the utilization rate of light energy properly. Non-imaging optics proposed a number of methods for secondary optic design of LED. In this paper, geometrical optics theory is used for the optic design of LED.A kind of spherical lenses system is designed to collimate the LED beams and distribute its light flux so to meet the requirements of illuminate in our daily life. For the characters of LED source and desired illumination, we set geometric model and simulate by optical software Zemax..
