Abstract: Various embodiments may relate to a lighting device including at least two light sources, the light from which has different spectra and is combined to form useful light. For measuring the portions of the light from the individual light sources, part of the useful light, the measurement light, is branched off with the aid of a coupling-out element at the output of the lighting device and is fed to a measuring device.
