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 11):
A light emitting device according to  claim 1 , wherein the luminescent element and the heat sink element are connected by means of a bonding material.
