Abstract

The illumination device has at least one reflector (2), at least one illumination zone (3) containing luminophore, and at least one laser (4). The at least one illumination zone can be excited by at least one laser to emit light, and at least some of the light emitted by the at least one illumination zone is incident on the at least one reflector.
