An electroluminescent light source comprising a substrate (1) and a layer structure applied to the substrate (1) for emitting light (10) at least on the side facing away from the substrate, said layer structure comprising at least one electrode as anode (3), at least one electrode as cathode (4) and at least one organic electroluminescent layer (2) located therebetween, wherein the electrode (4) is at least partially transparent on the side facing away from the substrate, and an at least partially transparent encapsulation device (5) for forming a closed volume (6) around the layer structure, which device is filled with a dielectric fluid (11) which is substantially chemically inert with respect to the layer structure, said fluid containing particles (12) for absorbing parts of the light emitted by the layer structure and for re-emitting light of a different wavelength, the density of said particles being selected such that the particles (12) in the dielectric fluid (11) are in the suspended state. |
