Abstract
A light module includes an excitation radiation source designed to emit an excitation radiation having a polarization, at least one first phosphor, an output, at which an output signal is providable, at least one first polarization beam splitter, a first polarization modulator arranged serially between the radiation source and the first splitter. The first modulator is designed to modify the polarization of the radiation source depending on a control signal. The first splitter is designed to split the radiation incident on it depending on the polarization between a first and a second of two optical partial paths connected in parallel with one another. The first optical partial path includes the at least one first phosphor and ends at the output of the light module. The second optical partial path, whilst bypassing the at least one first phosphor, ends at the output of the light module.
