| 摘 要： | 椭球面聚光镜是太阳模拟器设备的重要组成部分，其能量收集的效率决定着太阳模拟系统的能量传递效率，而太阳模拟器光学系统中的椭球面聚光镜参数一直没有理论上的设计依据，结合氙灯的发光特性并通过对MATLAB 中建立的椭球面聚光镜聚光过程数值分析模型给出了椭球面聚光镜包括第一焦距、最大成像放大倍率、包容角范围及前后开口直径的确定依据，并通过在Lighttools 中建立的4种仿真模型验证了理论分析的正确性。第一焦距由光源光中心高确定，最大成像放大倍率由光学积分器相对孔径及椭球镜包容角范围共同确定，椭球镜包容角范围不小于30°～120°，前开直径口由椭球镜的最大孔径角确定，后开口直径由最小孔径角和光源的径向调节量共同确定。该结论给椭球面聚光镜的设计提供了理论支撑，有利于设计完成高能量收集效率的椭球面聚光镜。

| Abstract: | The ellipsoid condenser is an important part of solar simulator. Light energy emitted from the light source can be collected and aggregated on the second focal plane, and the energy transmission efficiency is directly affected by this procedure. The efficiency of the energy collection procedure is determined by the ellipsoid condenser parameters. In order to increase the efficiency, the luminescence properties of xenon lamp were studied and the characters of the ellipsoid condenser condensation were analyzed by a model built in MATLAB. The ellipsoid condenser parameters such as the first focal length, the max imaging amplified ratio and the containing angle ranges could be determined after the study. The theory correctness was verified by 4 models built in Lighttools. The height of the light center determines the first focal length, the optical integrator F as well as the ellipsoid containing angles determine the max amplified ratio,and the containing angles should be 30°～120°, moreover the max angle determines the front hole diameter, the min angle and the radial adjustment of the light jointly determinate the back hole diameter. The ellipsoid condenser design can get theory support from the conclusions obtained in this paper, and the conclusions are helpful to accomplish a higher efficiency ellipsoid condenser. |
