Light-emitting organic component
View Patent ↗A light-emitting organic component is specified, comprising—an organic active region ( 3 ), in which light is generated during the operation of the component, and—an uneven light exit surface ( 6 ), through which at least part of the light generated in the organic active region ( 3 ) emerges from the component, wherein—a multiplicity of optical structures ( 7 ) which optically influence the light passing through and/or impinging on them are arranged at the uneven light exit surface ( 6 ).
1. A light-emitting organic component comprising:
an organic active region, in which light is generated during an operation of the light-emitting organic component; and
a non-planar light exit surface, through which at least part of the light generated in the organic active region emerges from the light-emitting organic component,
wherein a multiplicity of optical structures are arranged at the non-planar light exit surface and optically influence the light passing through and/or impinging on them,
wherein the non-planar light exit surface is a concavely and/or convexly curved surface which outwardly delimits the light-emitting organic component,
wherein an angular distribution of an intensity of the light emitted by the non-planar light exit surface is set by the optical structures,
wherein the angular distribution of the intensity becomes narrower toward edges of the non-planar light exit surface, in such a way that a self-illumination of the non-planar light exit surface with light generated in the organic active region is reduced or prevented, and
wherein at different locations of the non-planar light exit surface, the optical structures are embodied differently with respect to one another, thus resulting in different optical influencing of the light passing through and/or impinging on them.
2. The light-emitting organic component according to claim 1 , wherein a main emission direction of the light emitted by the non-planar light exit surface is set by the optical structures and varies along the non-planar light exit surface in such a way that the self-illumination of the non-planar light exit surface is reduced or prevented.
3. The light-emitting organic component according to claim 1 , wherein the non-planar light exit surface comprises at least two planar partial surfaces.
4. The light-emitting organic component according to claim 3 comprising at least two organic active regions, wherein each organic active region is assigned a planar partial surface.
5. The light-emitting organic component according to claim 1 , wherein light emerging from a first region of the non-planar light exit surface is emitted in a direction of a second region of the non-planar light exit surface and is directed away from the non-planar light exit surface by the optical structures in the second region.
6. The light-emitting organic component according to claim 1 , wherein an angular distribution of the intensity and/or of the color of the light emitted by the non-planar light exit surface is set by the optical structures.
7. The light-emitting organic component according to claim 6 , wherein the angular distribution of the intensity and/or of the color varies along the non-planar light exit surface.
8. The light-emitting organic component according to claim 1 , wherein a main emission direction of the light emitted by the non-planar light exit surface is set by the optical structures and varies along the non-planar light exit surface.
9. The light-emitting organic component according to claim 8 , wherein the main emission direction varies in such a way that the self-illumination of the non-planar light exit surface is at least reduced.
10. The light-emitting organic component according to claim 1 , wherein the optical structures comprise at least one of the following optical elements: prism, lens, light-scattering structures.
11. The light-emitting organic component according to claim 1 , wherein the optical structures are present as a foil which is applied to the non-planar light exit surface, wherein the foil is fixed to the non-planar light exit surface only in an edge region of said non-planar light exit surface and an air gap is formed between the non-planar light exit surface and the optical structures.
12. A light-emitting organic component comprising:
an organic active region, in which light is generated during an operation of the component; and
a non-planar light exit surface, through which at least part of the light generated in the organic active region emerges from the component,
wherein a multiplicity of optical structures are arranged at the non-planar light exit surface and optically influence the light passing through and/or impinging on them,
wherein an intensity of the light emitted by the non-planar light exit surface is set by the optical structures,
wherein in a third region in a center of the non-planar light exit surface the intensity has a wide angular distribution,
wherein in first and second regions in edge regions of the non-planar light exit surface the intensity has a narrower angular distribution as in the third region, and
wherein a lens form for the optical structures is different for the third region than for the first region and the second region.
13. The light-emitting organic component according to claim 12 , wherein the optical structures are present as a foil which is applied to the non-planar light exit surface, wherein the foil is fixed to the non-planar light exit surface only at said edges of said non-planar light exit surface and an air gap is formed between the non-planar light exit surface and the optical structures.
