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.

摘要： An illumination device comprising a plurality of solid state light sources and a concentrating wave length converter arranged to inject light from said light sources through at least one entrance surface and to extract wave length converted light from at least one exit surface, comprising a structured layer provided on said exit surface, said structured layer having a structure period less than 5 micrometers, thereby enabling out-coupling through the exit surface by a combination of refraction and diffraction. In a situation where the angle of incidence on a surface is within a limited range, a combination of refraction and diffraction may provide a superior out-coupling from that surface.
