An light-emitting apparatus and a method for producing a light-emitting apparatus are disclosed. In an embodiment, the apparatus includes at least one organic device and an outcoupling layer, wherein the at least one organic device emits electromagnetic radiation during operation, wherein the outcoupling layer contains optical structures, and wherein the apparatus has a non-Lambertian radiation distribution curve during operation. The outcoupling layer influences the radiation passing through it in an optically varying manner by the optical structures along a lateral direction in order to produce the non-Lambertian radiation distribution curve.

An optoelectronic assembly and method for operating an optoelectronic assembly are provided. In some aspects, the optoelectronic assembly includes an organic light-emitting component, a temperature sensor configured to record a temperature value, and a driver circuit coupled to the organic light-emitting component and the temperature sensor. The driver circuit is configured to apply an AC voltage to the organic light-emitting component when the organic light-emitting component is switched on, and if the recorded temperature value is less than a predetermined temperature threshold value, where the AC voltage is, at least, temporarily less than an instantaneous threshold voltage of the organic light-emitting component. The driver circuit is also configured to apply a DC voltage to the organic light-emitting component if a measurement value is greater than or equal to a predetermined threshold value, where the DC voltage is greater than the instantaneous threshold voltage of the organic light-emitting component.

A method for producing an organic light-emitting component is disclosed with providing a carrier, forming a first electrode over the carrier, forming an organic functional layer structure over the first electrode, and forming a second electrode over the functional layer structure. The first and second electrodes and the functional layer structure overlap in an optically active region which extends in the lateral direction and is embodied to generate light. In an optically inactive region extending over the carrier in the lateral direction, an electrically conductive contact layer is formed over the carrier, so that it is in direct physical and electrical contact with the first electrode and/or the second electrode. A first contact section and at least one second contact section of the layer are separated from one another by a lithographic process, so that they are electrically insulated from one another. The layer is structured by a laser beam.
