便携式太阳模拟器设计

Design of portable solar simulator

针对太阳模拟器小型化、便携性的实际需求,设计了一种便携式的太阳模拟器。要求在辐照面积1.2m×1.2m的矩形区域内的照度不小于0.02个太阳常数,且被照面的不均匀度小于5%。模拟器系统主要由短弧氙灯、椭球面反射镜、光纤传光束、积分棒和准直镜组组成。通过软件仿真及实验验证,结果均符合要求。实验结果表明,利用短弧氙灯、椭球面反射镜、光纤传光束、积分棒和投影准直透镜组设计便携式太阳模拟器的方法是有效、可行的。

For the miniaturization and portability demands of solar simulator, a portable solar simulator was designed. Illumination in 1.2 m ×1.2 m rectangular irradiated area not less than 0.02 solar constant was required; furthermore, the un-uniformity of irradiated surface less than 5% was also needed. The system mainly consisted of short-arc xenon lamp, ellipsoidal reflector, fiber optic beams, and a group of collimating lens. Through software simulation and experimental verification, the results met all the requirements. Experimental results show that the method that designing a portable solar simulator with short-arc xenon lamp, ellipsoidal reflector, fiber optic beams, integral stick, and projection collimator lens group is effective and feasible.
