Abstract
A UV light emitting diode (UV-LED) is arranged in a weathering chamber and a UV light receiving diode, which is constructed on the same material basis as the UV LED, is arranged relative to the UV LED in such a way that a portion of the radiation emitted by the UV LED impinges on the UV light receiving diode during the operation of the device.
