Abstract:
Aiming at the problems of low irradiation
uniformity and a narrow irradiance regulation range in the existing solar simulators, an optical design method for meteorological solar
simulators with high irradiation uniformity and wide-range irradiance is proposed. Using a xenon lamp and a variable coefficient non-coaxial
ellipsoid reflector as the concentrator system, we analyze the causes of stray light in the optical integrator. The optimal design method of
the integrator based on the anti-crosstalk diaphragm and the light propagation matrix model, which effectively suppress the stray light,
is proposed. The irradiance regulation system is designed to continuously regulate the irradiance in a wide range. The optimal
design method of the collimated system is given. The rationality of the system design is verified by the simulation of LightTools
software. The results show that within the effective irradiation surface of 100 m m × 100 m m , the irradiance is continuously
adjustable in the range of 100 − 1400 W / m 2 , and the irradiation uniformity is
better than 99.10% under different irradiances. This research breaks through the limitations of low irradiation uniformity and a narrow
irradiance adjustment range of traditional meteorological solar simulators and can provide accurate and reliable solar irradiance for
the verification and calibration of pyranometers.
