Beschreibung
Zusammenfassung:An illumination system comprising a radiation source and a composite monolithic ceramic luminescence converter comprising a composite luminescent material comprising at least one first phosphor and at least one second phosphor capable of absorbing a part of the light emitted by the radiation source and emitting light of a wavelength different from that of the absorbed light provides improved light mixing and chromaticity control of the emitted light mixture. The invention relates also to a composite monolithic ceramic luminescence converter and a method of manufacturing such composite monolithic ceramic luminescence converter.
