Abstract

The invention discloses a solar simulator. The solar simulator comprises a light source module and a reflecting module which are rotatably connected and is characterized in that the uniform convergedlight beam generated by the light source module enters the reflecting module, and the reflecting module outputs the uniform converged light beam to an irradiation face in a collimated manner. The solar simulator has the advantages that the light source module and the reflecting module are independently designed and can be separated during transportation and spliced during use, and small overall size and transportation and mounting convenience are achieved; the reflecting module adopts a three-reflector collimation optical system with the incoming direction and outgoing direction being orthogonal and is compact and lightweight in optical structure; the light source module and the reflecting module are rotatably spliced, and the outgoing direction of the collimated light beam can be adjustedby rotating the reflecting module.

Description

technical field [0001] The invention relates to the technical field of illumination optics, more precisely, to a solar simulator. Background technique [0002] The solar simulator is an experimental or calibration device that simulates the characteristics of solar radiation indoors. It is used to simulate the space environment on the ground to provide a uniform, collimated and stable irradiance that matches the solar spectrum. light source. Solar simulation technology is closely related to the development of space science, and is mainly used for spacecraft space environment simulation experiments. For example, in spacecraft vacuum thermal environment experiments, solar simulators are the most realistic and accurate means of heat flow simulation. The application of solar simulators can achieve high-precision The completion of the spacecraft thermal balance test. In addition, solar simulators have great application value in the fields of monitoring and calibration of solar c...
