Abstract
A solar simulator with at least one lamp module, where the luminous module contains multiple light generating units is disclosed. Each of the light generating units contain at least one semiconductor light source, which generate light in a plurality of separately controllable wavelength ranges. Disposed downstream from the light generating units is a light-concentrating primary optical unit. A light-homogenizing secondary optical unit is likewise disposed downstream of the light generating units. And an imaging tertiary optical unit is disposed downstream of the secondary optical unit. A method for operating the solar simulator and the light generating units in such a way that the solar simulator generates light radiation that alters over time is also disclosed.
