基于LED阵列光源的太阳模拟器
Solar simulator based on LED array light source
摘要
Abstract
Addressing the deficiencies of solar simulators,such as low radiation intensity and poor spectral matching,an LED solar simulator consisting of an LED array light source module,Fresnel focusing lens,optical integrator,and collimator lens is proposed.Firstly,according to the principle of multispectral fitting,15 LED light sources with different wavelengths are optimally selected in the spectral range of 400-1 100 nm,and their light source power is calculated to realize an exact match of the solar spectrum.Secondly,the design of the Fresnel lens,optical integrator,and collimator lens is optimized to correct the aberrations of the sun simulator and improve its energy utilization efficiency and irradiation surface nonuniformity.The optical system is simulated using the LightTools software. Finally,an experimental device of the optical system is built,its fitted spectra reaching the A level ac-cording to the AM1.5 conditions,a radiation intensity of 1 376.3 W/m2 from an area of 100 mm×100 mm,an irradiation nonuniformity of ± 1.73 %,and an irradiation instability of ± 0.82 %.The o-verall performance of the solar simulator satisfied the T riple-A level.关键词
