Claim:
1. A lighting apparatus, comprising: a light generating device for generating a primary light; a first luminophore for the wavelength conversion of the primary light into a first secondary light; and a second luminophore for the wavelength conversion of the primary light into a second secondary light; and wherein: the first luminophore is situated on a movable carrier, which is configured to alternately introduce and remove the first luminophore into and from a beam path of the primary light, the second luminophore is situated on a stationary carrier, the movable carrier is a rotatable luminophore wheel having a plurality of segments passing through into the beam path of the primary light, at least one luminophore segment comprises the first luminophore, at least one transmitted-light segment is a segment that is transmissive at least for the primary light and the second secondary light, at least one reflector segment is a segment that reflects at least the primary light, primary light emitted by the light generating unit can be radiated through the transmitted-light segment onto the second luminophore, and second secondary light emitted by the second luminophore can be radiated back through the transmitted-light segment.
