Abstract
In a weathering chamber, a UV radiation device is arranged and at least one sample can be arranged in a sample plane spaced apart from the UV radiation device. The UV radiation device has a plurality of UV light emitting diodes (UV LEDs) containing two or more classes of UV LEDs having different emission bands. The emission bands are chosen in such a way that a spectral distribution with which a specific spectral UV characteristic is approximated can be obtained in the sample plane.
