基于菲涅尔透镜的大功率LED均匀照明系统设计
Design of high power LED uniform illumination system based on Fresnel lens
摘要
Abstract
In order to make up for the shortcomings of wireless communications, the development of high-power white LED communication technology is very necessary. Based on the idea of conservation of op-tical extension, a high power LED uniform light source based on Fresnel lens and compound paraboloid re-flector is proposed. First of all, the mirror cross-section curve is obtained through theoretical design, and then the Tracepro software is used for modeling and ray tracing simulation. The optimal simulation parameters are obtained for processing to achieve an uniform light source system entity. Finally, an uniform light source with a divergence angle of about 2.63°at a distance of 2.5m from the light source, an uniform light uniformity of better than 94.40% in the effective area of the light spot, and an overall light extraction efficiency of more than 80% is achieved.关键词
