Problems solved by technology

This method is realized by changing the power of the light source, and due to the influence of the stability of the light source, the change of power will destroy the uniformity and stability of the solar simulator's irradiation, thereby reducing the accuracy level of the solar simulator, and even affecting the normal operation of the solar simulator. use
And when the solar simulator irradiance is lower than 250W / m 2 When the voltage regulation method is difficult to play the role of adjusting the irradiance

Abstract

A shading device that is continuously adjustable for solar simulator irradiation is designed. It consists of a three-top and three-pull adjusting mechanism, a shading plate structure, and an auxiliary rotating structure. The auxiliary rotating structure drives the shading plate structure, which can realize the two The relative rotation between the superimposed circular shading plates with fan-shaped light holes, so as to realize the solar simulator without changing the solar collimation angle and greatly reducing the irradiation uniformity, irradiation stability and irradiation spectral distribution. The irradiance is continuously adjusted. At the same time, the pitch angle of the shading plate structure relative to the rear light propagation path of the concentrating system is adjusted by the three-top and three-pull adjustment mechanism to make up for the abnormal irradiation distribution of the irradiation surface caused by the installation and adjustment error.

Description

technical field [0001] The invention relates to the field of solar simulator irradiation regulation, in particular to a shading device that is continuously adjustable for solar simulator irradiation. Background technique [0002] The solar simulator can realize the real simulation of solar irradiance, solar collimation angle, irradiance stability and uniformity, etc. under laboratory conditions, using a concentrating system and a uniform light system, and a light source close to the solar spectrum. The key component of attitude measurement in satellite control system - equipment used for ground simulation test and calibration in the development of solar sensor. [0003] Judging from the existing research results, the simulation of solar irradiance, collimation angle and spectral distribution has been relatively perfect. But there are still many problems in the study of irradiance regulation of solar simulators. The voltage regulation and current regulation method is most c...
