Realization of LED Solar Simulator Matching and Irradiance Unevenness
Six kinds of high power LED which have peak wave length of 460, 525, 625, 730, 850, 940 nm respectirdy. The light source of the LED solar simulator meets the intensity of 1 solar irradiation on the effective radiation surface, and also achieves the level of spectral matching. In this design, the irradiation nonuniformity index is six wavelength combination of LED light source in the effective irradiated surface inhomogeneity of energy. In order to reduce nonuniformity on the effective irradiated surface of the LED solar simulator, we combine design process with optical characteristics of LED light emitting angle, and pointedly realize multiple converging optical systems. Through the control of LED light source array, we have achieved 160 mm×160 mm A-level standard of non-uniformity on effective irradiation area. According to the international standard, the standard of the LED solar simulator reaches the level of the AAA level solar simulator standard.
