摘要:
An electroluminescent device comprising at least one electroluminescent light source (2) with an electroluminescent layer (21) for emitting a primary radiation with an emission characteristic around a mean emission direction (5), and at least one light-converting element (3) for converting at least part of the primary radiation into a secondary radiation, wherein the shape of the light-converting element (3) is adapted to the emission characteristic of the electroluminescent light source (2) so as to generate a defined correlated color temperature as a function of a viewing angle (10).
