ABSTRACT:
An organic electroluminescent light source has at least one substrate and layers that are arranged on the substrate. The layers include electrodes of which at least one electrode is transparent and one acts as an anode and one as a cathode, and at least one organic electroluminescent layer that is arranged between the electrodes. The organic electroluminescent layer has regions that emit blue light and/or green light, and at least one phosphor layer that is arranged in the beam path of the light leaving the organic electroluminescent light source and that partly covers the electroluminescent layer.
