Abstract:
A light emitting device ( 1 ) comprising a luminescent element ( 3 ) comprising a first face ( 31 ) and a second face ( 32 ), the first face comprising a light input surface and one of the first face and the second face comprising a light exit surface, the luminescent element ( 3 ) being adapted for receiving first light ( 4 ) with a first spectral distribution emitted by at least one laser light source ( 21, 22, 23 ) at the light input surface, converting at least a part of the first light with the first spectral distribution to second light ( 5 ) with a second spectral distribution, guiding the second light with the second spectral distribution to the light exit surface and coupling at least a part of the second light with the second spectral distribution out of the light exit surface, and a heat sink element ( 7 ) arranged to be in thermal contact with at least a part of the luminescent element ( 3 ) extending between the first face ( 31 ) and the second face ( 32 ), wherein the first face ( 31 ) comprises a cross-sectional area A and the luminescent element ( 3 ) further comprises a length L being defined as the shortest distance between the first face and the second face and a characteristic length B of the cross sectional area A, the characteristic length B being defined as the square root of the cross sectional area A, and wherein, and wherein the length L and the characteristic length B of the cross sectional area A are chosen such that they satisfy any one of the relations L/B≥2*E lls /44(W/mm 2 ) for λ THC <6 W/mK, L/B≥1.3*E lls /44(W/mm 2 ) for 6 W/mK≤λ THC ≤8 W/mK, and L/B≥0.85*E lls /44(W/mm 2 ) for 8 W/mK<λ THC , where E lls  is the irradiance of the at least one laser light sources measured in W/mm 2  and λ THC  is the thermal heat coefficient of the luminescent element at room temperature.

Claim (Index 9):
A light emitting device according to  claim 1 , wherein the first face of the luminescent element comprises both the light exit surface and the light input surface, and wherein the heat sink element furthermore is arranged to be in thermal contact with the second face of the luminescent element.
