Patent ID: 7768198

Claim:
An electroluminescent light source having a substrate, a layer structure applied on the substrate for emitting light at least on the other side from the substrate, having at least one electrode as an anode, at least one electrode as a cathode and at least one organic electroluminescent layer lying between them, the electrode on the other side from the substrate being at least partially transparent, and an at least partially transparent encapsulation device for forming a closed volume around the layer structure, which is filled with a dielectric liquid that is substantially chemically inert with respect to the layer structure and which contains particles of a non-absorbent material, for scattering light, the density of which is selected so that the particles are in the suspended state in the dielectric liquid, wherein the particles consist of at least one first material having a density greater than the density of the dielectric liquid and at least one second material having a density less than the density of the dielectric liquid.
