Abstract

The invention provides a portable uniform solar light source with large irradiation surface and high irradiance, which includes a parabolic condenser 101, a short-arc xenon lamp 102, a protective glass 103, a short-arc xenon lamp installation and adjustment mechanism 201, a parabolic condenser installation and adjustment mechanism 202, and a protective glass installation Seat 203, box body 204, support base 205, No. 1 axial fan 301, No. 2 axial fan 302, No. 3 axial fan 303, No. 4 axial fan 304, No. 5 axial fan 305 and No. 6 axial fan Fan 306 is formed. The short-arc xenon lamp 102 is located at the focal point F of the parabolic condenser 101, and can form a uniform light spot with an irradiation area of ​​500mm and an irradiation intensity of 1353w / ㎡ at a working distance of 1500mm.

Description

technical field [0001] The invention relates to the space vehicle ground calibration technology, in particular to a portable large-size high-irradiance uniform solar light source. Background technique [0002] Coarse solar sensor is an analog solar sensor composed of multiple photocell configurations. It has a simple structure and requires less resources, and is widely used in pico-satellite platforms. Photovoltaic output characteristics of photovoltaic cells are the basis for crude solar sensor measurements. [0003] As a ground device for testing the photovoltaic output characteristics of photovoltaic cells, the solar simulator is required to simulate the solar radiation characteristics, including irradiance, spectral matching, spot diameter, spot divergence angle and irradiation uniformity. [0004] At present, the solar simulators successfully developed at home and abroad can simulate the characteristics of solar radiation more accurately and comprehensively, but they a...
