▎ 摘　　要

NOVELTY - The color conversion arrangement (140) includes a luminescent layer (110), a supporting layer (106) and a graphene layer (108). The luminescent layer comprises a 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 graphene layer thermally conducts heat in a lateral direction. USE - Color conversion arrangement for use in lighting unit, solid state light emitter package, or luminaire (all claimed) for converting light of first color to light of another color. ADVANTAGE - Temperature differences in the color conversion arrangement are reduced since the graphene layer thermally conducts heat in a lateral direction. The supporting layer does not have to withstand these large temperature differences and may, optionally, be manufactured of a less expensive material. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of a color conversion arrangement.
