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 continuously adjustable shading device for irradiation of a solar simulator is designed, the shading device is composed of a three-jacking three-pulling adjusting mechanism, a shading plate structure and an auxiliary rotating structure, the shading plate structure is driven by the auxiliary rotating structure, and relative rotation between two stacked circular shading plates with fan-ring-shaped light through holes in the shading plate structure can be achieved; and therefore, the irradiance of the solar simulator can be continuously adjusted without changing a sun collimation angle and greatly reducing the irradiation uniformity, the irradiation stability and the irradiation spectrum distribution. Meanwhile, the pitch angle of the shading plate structure relative to the light propagation path behind a light condensing system is adjusted through the three-jacking three-pulling adjusting mechanism, and the abnormal irradiation distribution of the irradiation surface caused by installation and adjustment errors is made up.

Description

technical field [0001] The invention relates to the field of solar simulator radiation regulation, in particular to a continuously adjustable shading device for solar simulator radiation. Background technique [0002] The solar simulator can realize the real simulation of solar irradiance, solar collimation angle, radiation stability and uniformity, etc. The key component of attitude measurement in the satellite control system - the equipment used for ground simulation test and calibration in the development of sun sensor. [0003] Judging from the existing research results, the simulation of solar irradiance, collimation angle and spectral distribution has been done relatively well. However, there are still many problems in the study of irradiance regulation of solar simulators. The voltage regulation and current regulation method is most commonly used to adjust the irradiance of the solar simulator. This method is realized by changing the power of the light source, and ...
