Abstract:
A light emitting system (1) comprising a radiation source (2) capable of emitting a first light of at least a first wavelength spectrum; a first fluorescent material (4) capable of absorbing at least partially the first light and emitting second light having a second wavelength spectrum; a second fluorescent material (8) capable of absorbing at least partially the first light and emitting a third light having a third wavelength spectrum; wherein one, the first (4) or the second fluorescent material (8) is a polycrystalline ceramic with a density of more than 97 percent of the density of a monocrystalline material and the respective other fluorescent material is a phosphor powder with a median particle size 100 nm
