摘要： 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 (140) with the first aspect comprises a first luminescent layer (110), a supporting layer (106) and a first graphene layer (108). The color conversion arrangement (140) is for converting light of a first color to light of another color. The first luminescent layer (110) 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 (106) supports the luminescent layer (110). The first graphene layer (108) thermally conducts heat in a lateral direction such that temperature differences in the color conversion arrangement (140) are reduced. Different arrangements of the layers of the color conversion arrangement (140) are provided.

摘要： The present invention relates to lighting module, wherein a light exit window (12) of the lighting module is engraved such that the output color temperature of said lighting module is tuned. The present invention also relates to a method for tuning an output color temperature of a lighting module, said method comprising providing said lighting module comprising a light exit window (12), and a light source arranged to provide light having an optical path through said light exit window (12), said lighting module having a first output color temperature; and engraving a surface of said light exit window (12) such that the output color temperature of said lighting module is tuned to a second output color temperature.
