摘要
基于非成像光学理论,根据固体照明光源LED特性,开展了车用照明准直光学镜头的优化研究。以非成像光学的理论为基础,从现有准直透镜结构出发,建立了简化的LED准直照明结构模型,并利用光学仿真设计软件Zemax对简化的模型进行了优化设计;利用三维建模软件SolidWorks建立准直结构模型,导入光学仿真软件TracePro中进行仿真分析并进一步优化,优化后的准直透镜光能利用率提高了6%;根据优化结果开模制作准直结构样品;最后,建立测试系统,开展优化前后透镜的光学性能对比测试。研究结果表明,5m处中心最大光强提高了约128%,在相同照度(50lx)处照射面积提高了约25%。
The lighting collimating lens is designed for the use of headlight of automobile, in which LED is used as lighting source. Firstly, the simplified illumination structure model is built, which is designed based on the theory of non-imaging optics and the parameters of traditional lenses. The structure is optimized by optical simulation software Zemax. Secondly, the three-dimensional （3D） model of lens is set up by SolidWorks software and simulated by TracePro. The results show that the optimized lens＇ light-use efficiency is improved by about 6%. Thirdly, the optimized lens is made and prepared for test. Finally, the experimental system is set up, by which the optical characteristics of the traditional and optimized lenses are investigated. The results show that the maximum light intensity is improved by about 128% at 5 m away and the irradiated area at the same illumination （50 lx） is enlarged by about 25 %.
