摘要

基于复合抛物聚光器理论、几何光学中的边缘射线原理和离轴射线追迹理论，提出了一种设计大尺寸LED反射器的新方法，使其在一定角度范围内产生均匀照明。利用该方法可以定量地推导出LED反射器的结构，从而达到高能效和均匀性的目的。在光学设计软件ZEMAX中进行仿真，结果表明该方法是合理的。

Reflector design method based on compound parabolic concentrator(CPC)for big size LED

A new method based on the theory of compound parabolic concentrator(CPC),the edge-ray principle and the off-axis rays tracing theory in geometrical optics is proposed to design a reflector for big size LED to generate uniform illumination in a certain range of angle.The structure of LED reflector can be quantitative deduced by using this method to achieve high energy efficiency and uniformity.Simulating in the optical design software ZEMAX shows that the method is reasonable.

期刊介绍： The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months. The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
