A lighting device is provided with a pump radiation source for emitting pump radiation, a first phosphor element for converting the radiation into a first conversion light, a second phosphor element for generating a second conversion light, and a coupling-out mirror arranged downstream of the first element in a beam path with at least part of the first light. The first light is a broadband conversion light having components in first and second spectral ranges, and the coupling-out mirror is transmissive only in one of the two ranges such that, lights having first and second spectral components in the first and second spectral ranges are separated. The second element is arranged in a beam path with the light having the second component and, in response to this excitation, emits the second light, which can be used jointly with the light having the first component in order to increase the efficiency.
