| 摘 要： | 针对现有LED太阳模拟器同时解决准直性、辐照度均匀性、光谱匹配性三大技术指标的难度较高的问题，基于光电一体化二次光学设计，提出一种简便、高效且可实现大功率的LED太阳模拟器光学系统设计方法。采用小角度准直透镜和抛物面镜来整合光源，通过混光棒和微结构进行匀光，最后利用抛物面镜实现光线的准直输出，基于同轴准直的设计思想完成LED太阳模拟器的设计。利用光学软件LightTools对LED太阳模拟器光学系统进行模拟仿真与分析优化，实验结果表明:在直径为260 mm的有效辐照面上辐照不均匀度为2.5%、准直角为1.5°。

| Abstract: | In order to solve the difficult problems of collimation,irradiance uniformity and spectral matching of existing LED solar simulators,a simple,efficient and high-power optical system design method of LED solar simulator was proposed based on photoelectric integrated secondary optical design.The small angle collimating lens and the parabolic mirror were utilized to integrate the light source,and the mixing light rod and microstructure were used to homogenize the light,finally the collimating output of light was realized by the parabolic mirror.Based on the design idea of coaxial collimation,the design of the LED solar simulator was completed.In addition,the optical software LightTools was used to simulate and optimize the optical system of LED solar simulator.The experimental results show that the irradiation inhomogeneity is 2.5%and the collimation angle is 1.5°on the effective irradiation surface with a diameter of 260 mm. |
