摘要： An electroluminescent light source includes a substrate and a layer structure applied to the substrate for emitting light at least on the side facing away from the substrate. The layer structure includes an electroluminescent layer between two electrodes. A partially transparent encapsulation device forms a closed volume around the layer structure, and is filled with a dielectric fluid which is substantially chemically inert with respect to the layer structure. The fluid contains particles for absorbing parts of the light emitted by the layer structure and for re-emitting light of a different wavelength. The density of the particles is selected such that the particles in the dielectric fluid are in the suspended state in the operational state of the light source.
