View Patent ↗An organic luminous means and an illumination device comprising such a luminous means are described. An optical display apparatus, emergency lighting, motor vehicle interior lighting, an item of furniture, a construction material, a glazing and a display comprising such a luminous means and, respectively, comprising an illumination device having such a luminous means are also described.
1. An illumination device comprising:
a first light source, which emits light of a first color; and
a second light source, which emits light of a second color, which is different from the first color;
wherein at least one of the two light sources is dimmable;
wherein the first light source is provided by a luminous means comprising:
a substrate having a first main surface, to which a first electrode is applied,
a second electrode, and
an organic layer stack within an active region of the substrate between the first and the second electrode, the organic layer stack comprising at least one organic layer configured to generate light; and
wherein the luminous means and the second light source are arranged with respect to one another such that light from the second light source passes through the luminous means.
2. The illumination device as claimed in claim 1 , wherein one of said first and second color lies in a yellow spectral range and the other color lies in a blue spectral range.
3. The illumination device as claimed in claim 1 , wherein one of said first and second color lies in a warm white region of a CIE standard chromaticity diagram and the other color lies in a cold white region of the CIE standard chromaticity diagram.
4. The illumination device as claimed in claim 1 , wherein the luminous means is dimmable.
5. The illumination device as claimed in claim 1 , wherein the second light source is dimmable.
6. The illumination device as claimed in claim 1 , wherein the second light source is formed by at least one of the following elements: an incandescent lamp, at least one individual light-emitting diode, a light-emitting diode module, a cold cathode lamp, a fluorescent lamp, a lava lamp and an organic light-emitting diode.
7. The illumination device as claimed in claim 1 , wherein the luminous means is flexible and transmissive to visible light.
8. The illumination device as claimed in claim 1 , wherein the luminous means comprises a lampshade.
9. The illumination device as claimed in claim 1 , wherein mixed-colored light comprising light from the luminous means and light from the second light source is emitted during operation of the illumination device.
10. An illumination device comprising:
a first luminous means and a second luminous means which are electrically and mechanically connected to one another, each of said first and second luminous means comprising:
a substrate having a first main surface, to which a first electrode is applied,
a second electrode, and
an organic layer stack within an active region of the substrate between the first and the second electrode, the organic layer stack comprising at least one organic layer configured to generate light,
wherein the first luminous means includes at least one connection location which comprises a connection pin arranged at a side surface of the substrate of the first luminous means, and
wherein the connection pin engages into a connection location of the second luminous means which comprises a cutout in a side surface of the second luminous means.
11. The illumination device as claimed in claim 10 , wherein the first and the second luminous means are mechanically connected to one another by a cylindrical interference fit via the connection locations.
12. The illumination device as claimed in claim 10 , wherein the first and the second luminous means are mechanically connected to one another by a press fit by means of the connection locations.
13. The illumination device as claimed in claim 10 , wherein the first and the second luminous means are mechanically connected to one another by a plug connection by means of the connection locations.
14. The illumination device as claimed in claim 10 , comprising:
a carrier by which the first and second luminous means of the illumination device are at least one of mechanically and electrically connected to one another.
15. The illumination device as claimed in claim 14 , wherein the carrier comprises one of a carrier plate, a carrier grid, a cable system and a rod system.
