摘要： A light emitting device (1) comprising at least one light source (2) adapted for, in operation, emitting first light (13) with a first spectral distribution, a light guide (4) made of a luminescent material and comprising a light input surface (41) and a light exit surface (42) extending in an angle different from zero to one another, the light guide further comprising a first further surface (46) extending parallel to and arranged opposite to the light exit surface, wherein the light guide is adapted for receiving the first light (13) with the first spectral distribution at the light input surface, converting at least a part of the first light with the first spectral distribution to second light (14) with a second spectral distribution, guiding the second light with the second spectral distribution to the light exit surface and coupling the second light with the second spectral distribution out of the light exit surface. The light emitting device further comprises a phosphor element (77) arranged adjacent to the first further surface and a reflective element (76) arranged adjacent the phosphor element opposite to the first further surface (46). The phosphor element is adapted for converting light incident from the light guide to third light (17) with a third spectral distribution and the light guide (40) is furthermore adapted for receiving the third light (17) with the third spectral distribution at the first further surface (46), guiding the third light (46) with the third spectral distribution to the light exit surface (42) and coupling the third light with the third spectral distribution out of the light exit surface.
