Beschreibung
Zusammenfassung:	An illumination apparatus includes a first solid-state-based illumination module, a second solid-state-based illumination module, and a superposition unit, which couples first and the second luminescence radiation into an illumination beam path, in which said radiation is guided up to the end of the illumination beam path in order to illuminate a light modulator. A filter unit which filters light with a second color from the first luminescence radiation with a first color and from the second luminescence radiation such that light with the first and second color is present at the end of the illumination beam path.
