LED太阳模拟器的研究

Study of LED Solar Simulator

设计了一种新型太阳模拟器。该太阳模拟器是采用不同波长的LED复合成太阳光源来实现太阳光模拟的。使用软件对其进行了原理上的仿真并进行了验证性实验。实验表明该设计方案可行的。该LED太阳模拟器具有全光谱模拟太阳的功能,将打破现在普遍用的气体光源来模拟太阳的局部光谱的功能障碍,与同类系统相比,其优点是成本低、易于实现。

A new type of solar simulator was designed. The solar simulator simulated the solar energy by using the Light-emitting Diodes （LED） of different wavelengths as a compound solar source. It was simulated in principle and was tested in a verification experiment. The experiment showed that this design scheme was feasible. The LED solar simulator had the function to simulate solar energy in all spectra. It would overcome the function obstacle of the current gas light source commonly used to simulate partial solar spectra. Compared with other solar simulator systems, it had the features of low cost and easy implementation.
