Claim Text:
1. A light emitting diode arrangement, comprising at least one first light emitting diode chain having a first plurality of series-connected light emitting diodes; at least one second light emitting diode chain having a second plurality of series-connected light emitting diodes; a circuit arrangement for coupling the first and second light emitting diode chains to a supply source, which provides a temporally varying voltage; wherein the light emitting diodes are arranged at least partly on at least one first arrangement surface; wherein the circuit arrangement is configured in such a way that the first light emitting diode chain and second light emitting diode chain in each case can be coupled to the supply source and can be decoupled from the supply source, wherein the first light emitting diode chain can be coupled to the supply source at first points in time and the second light emitting diode chain can be coupled to the supply source at second points in time, wherein the first points in time differ from the second points in time; wherein the circuit arrangement is configured in such a way that, in the case of a coupling of the light emitting diode arrangement to the supply source, a current having a first average current intensity flows through the first light emitting diode chain and a current having a second average current intensity flows through the second light emitting diode chain, said second average current intensity differing from the first average current intensity at least owing to the difference between the first and second points in time; wherein the light emitting diodes of the at least one first and second light emitting diode chain are arranged according to a predefined criterion depending on their average current intensities, wherein the light emitting diode arrangement has at least one second arrangement surface, wherein the at least one first and second arrangement surface are arranged on at least one main body, wherein the normal vectors of the at least one first arrangement surface differ in terms of their direction from the normal vectors of the at least one second arrangement surface, wherein an orientation of the normal vectors points away from the at least one main body, and wherein the separation is configured in such a way that the light emitting diodes of the at least one first light emitting diode chain are arranged on the at least one first arrangement surface and the light emitting diodes of the at least one second light emitting diode chain are arranged on the at least one second arrangement surface.
