Abstract

The invention provides a portable even sun light source with a large irradiation face and high irradiance. The portable even sun light source comprises a parabolic collecting lens 101, a xenon short-arc lamp 102, protection glass 103, a xenon short-arc lamp mounting adjustment mechanism 201, a parabolic collecting lens mounting adjustment mechanism 202, a protection glass mounting seat 203, a box 204, a supporting base 205, a first axial flow fan 301, a second axial flow fan 302, a third axial flow fan 303, a fourth axial flow fan 304, a fifth axial flow fan 305 and a sixth axial flow fan 306. The xenon short-arc lamp 102 is located at the focal point F of the parabolic collecting lens 101, and can form even light spots with the irradiation area being 500 mm and the irradiation intensity being 1353 w/m<2> when the work distance is 1500 mm.

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...
