Patent ID: 8264142

Claim:
An illumination apparatus with an inorganic light-emitting device with a first light exit area and an organic light-emitting device with a second light exit area larger than the first light exit area, wherein the inorganic light-emitting device and the organic light-emitting device are arranged so that a planar light output in which light of the inorganic light-emitting device and light of the organic light-emitting device superimpose each other results, wherein the inorganic light-emitting device and the organic light-emitting device radiate equally colored light, and the organic light-emitting device is formed as a planar luminaire and comprises a transparent portion, and the inorganic light-emitting device is mounted to the organic light-emitting device so as to radiate its light through the transparent portion so that the inorganic light-emitting device and the organic light-emitting device radiate their light in the same direction of radiation perpendicular to a planar extension of the organic light-emitting device, and the first light exit area is embedded in the second light exit area in a projection along the direction of radiation.
