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.

Embodiment Construction

[0032] The present invention will be further described below in conjunction with the embodiments and the accompanying drawings. But it should not limit the protection scope of the present invention.

[0033] Please refer to Fig. 1 first. Fig. 1 is an outline drawing of the continuous xenon lamp of the present invention. The lamp tube 3 of the xenon lamp is made of high-quality doped quartz glass tube. The shape of the isolation trench is used to improve its high-temperature radiation self-cooling performance and reduce the operating temperature of the conduction part. An auxiliary electrode (wire) can also be added to the xenon lamp to help start.

[0034] When the xenon lamp is working, the forced air cooling method is adopted.

[0035] Usually, long-arc xenon lamps are powered by AC mains. The advantage is that the power supply is simple and the power supply is high, but its AC ripple is large and the light is unstable. When working with DC, it often requires a bulky power...

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...
