Abstract
The invention provides a color conversion arrangement, a lighting unit, a solid state light emitter package, a luminaire and a specific use of a graphene layer. A color conversion arrangement () with the first aspect comprises a first luminescent layer (), a supporting layer () and a first graphene layer (). The color conversion arrangement () is for converting light of a first color to light of another color. The first luminescent layer () comprises a first luminescent material which absorbs a portion of light of a first spectral distribution comprising the first color and converts at least a portion of the absorbed light towards light of a second spectral distribution. The supporting layer () supports the luminescent layer (). The first graphene layer () thermally conducts heat in a lateral direction such that temperature differences in the color conversion arrangement () are reduced. Different arrangements of the layers of the color conversion arrangement () are provided.
