Description

technical field [0001] The invention relates to a light source, in particular to a solar cell array lighting device for simulating a space lighting environment. The equipment is mainly used to simulate the space lighting environment to detect the correctness of the output power of each charging array of the large-area solar cell array loaded on satellites and other aerospace devices and equipment, as well as the matching of the connection between the sub-arrays and the working output of the load. Correctness, etc., is one of the important ground detection methods in aerospace technology, and it can also be used to test civilian fields such as the power generation efficiency of ordinary solar cell arrays. Background technique [0002] The simulation technology of solar irradiation conditions is a technique for studying and simulating the characteristics of solar radiation, including solar spectral characteristics, total solar irradiance, solar collimation angle, irradiance no...

AI Technical Summary

Problems solved by technology

The existing solar cell array lighting equipment at home and abroad mostly use short-arc xenon lamps, iodine-tungsten lamps and other light sources to simulate different solar irradiation conditions, but there are usually problems such as complex structure, high cost or low color temperature, and, For large-area irradiation, the radiation efficiency and solar constant of these light sources are limited to a certain extent, which cannot meet the test requirements.
