Multi-light-source-mixing sun simulation device

The invention discloses a multi-light-source-mixing sun simulation device. The device comprises a xenon lamp, a xenon lamp spotlight system, an optical integrator, a collimation optical system, a semi-reverse semi-permeable mirror, an LED array and an LED optical system; a simulation light beam of the sun simulation device comes from two optical sources of the xenon lamp and the LED array, under the effect of the semi-reverse semi-permeable mirror, parallel light given out by the xenon lamp and parallel light given out by the LED array are combined, and on the basis of large irradiance, the simulation precision of high spectrum is superimposed. 一种多光源混合的太阳模拟装置，包括氙灯、氙灯聚光系统、光学积分器、准直光学系统、半反半透镜、LED阵列和LED光学系统；太阳模拟装置的模拟光束来自两个光源，分别是氙灯和LED阵列，在半反半透镜的作用，将氙灯发出的平行光与LED阵列发出的平行光进行合束，在大辐照度的基础上，叠加了高光谱模拟精度。
