in a polymer matrix that is the first light output side 1 in the exemplary embodiment of fig4 a comprises a material that is light diffusing this means that the color components as well as the intensity of the light 21 released through the first light output side 1 can be modified fig4 b shows the emission improvement v in percent plotted as a function of the wavelength of the light 21 emitted from the first light output side for an angle of 0 degrees curve 15 relative to the surface normal n and an angle of 60 degrees curve 16 relative to the surface normal n fig5 shows a fifth exemplary embodiment of a lighting device described here in a schematic sectional view in this exemplary embodiment particles 10 of a color filter and or wavelength conversion material are introduced into the substrate 8 of the lighting device that is the first light output side 1 comprises a color filter material and or a wavelength conversion material the organic layer 3 a provided for generating radiation is suitable for example for emitting blue light the particles 10 can be for example particles of a yellow re emitting or a red green re emitting wavelength conversion material in this way a white mixed light is emitted from the first light output side 1 blue light is emitted from the second light output side 2 alternatively it is also possible for example that the organic layer 3 a provided for generating radiation is suitable for generating white light in that case the particles 10.
