A light module includes an excitation radiation source, first phosphor, a beam splitting apparatus configured to generate a first and a second partial optical path, with one of the two partial optical paths comprising the first phosphor and the other one including the excitation radiation, a combining apparatus to merge the first and second paths, and an exit where the radiation from the merged paths can be made available. The apparatus includes a first rotatably mounted filter wheel is arranged between the source and the first phosphor and has a first transmission region and a first reflection region for the excitation radiation, and a second rotatably mounted filter wheel, which has at least one second transmission region and a second reflection region for the excitation radiation. |

1. A light module, comprising:
an excitation radiation source which is configured to emit excitation radiation; at least one first phosphor which is configured to convert the incident excitation radiation to first conversion radiation; a beam splitting apparatus which is configured to generate at least a first and a second partial optical path, with one of the two partial optical paths comprising the at least one first phosphor and the other one comprising, at least during specifiable time periods, the excitation radiation; a combining apparatus which is configured to merge at least the first and the second partial optical path; and an exit where the radiation from the merged partial optical paths can be made available as an output signal; wherein the beam splitting apparatus comprises a first rotatably mounted filter wheel, which is arranged between the excitation radiation source and the at least one first phosphor and has at least one first transmission region and at least one first reflection region for the excitation radiation, and at least a second rotatably mounted filter wheel, which has at least one second transmission region and at least one second reflection region for the excitation radiation; wherein with the first and the second filter wheel being arranged with respect to one another such that at least the first transmission region, the first reflection region, the second transmission region, and the second reflection region together define a total transmission region and a total reflection region. |
