Solar radiation system sunlight simulator, commonly known as a solar simulator, will be introduced from its principles, structure, applications, and other dimensions as follows:

working principle

By using a special lighting system to generate a spectral distribution similar to sunlight, the light source emits light, which is then shaped, filtered, and collimated by an optical system to simulate the spectral distribution and irradiance of sunlight.

Solar radiation system sunlight simulatorbasic structure

-Light source: Xenon lamp, metal halide lamp orLEDLights, etc. Xenon lamp light source has a wide spectral range and high brightness;LEDThe light source has a long lifespan and good stability.

-Optical system: including reflector, optical integrator, shutterAM1.5Filters, collimating lenses, etc. are responsible for shaping, filtering, and collimating light rays to simulate spectral distribution and irradiance similar to sunlight.

-Control system: used to control light source switches, adjust light intensity, monitor spectral quality, etc., and can achieve automated operation and remote monitoring.

Solar radiation system sunlight simulatorperformance metrics

-Total irradiance: The simulator needs to achieve on the test plane1000W/The standard irradiance per square meter can be adjusted around the standard value.

-Spectral matching: The spectral irradiance distribution of the simulator should match the standard spectral irradiance distribution, gradeAThe matching degree is0.75-1.25.

-Uniformity: The irradiance in the testing area should reach a certain level of uniformityAUniformity of irradiation<=+/-2%.

-Radiation stability: During data collection, the radiation should have a certain degree of stability and levelAThe stability is<=+/-2%.
