Abstract: An optocoupler has an organic light emitter and an inorganic photodetector with a detector area, the detector area being optically coupled to the organic light emitter. The organic light emitter converts an electrical input signal into a light signal and the inorganic photodetector converts the light signal into an electrical output signal, the organic light emitter and the inorganic photodetector being integrated in a component and galvanically separated.

Abstract: There is described an illumination apparatus with an organic light-emitting device with a first light exit face and an organic light-emitting device with a second light exit face larger than the first light exit face. The inorganic light-emitting device and the organic light-emitting device are arranged so that a planar light output in which light of the inorganic light-emitting device and light of the organic light-emitting device superimpose each other results.

Abstract: A light-emitting diode matrix comprises a substrate, first and second electrodes electrically insulated from each other formed in or on the substrate, and a first organic layer on the first electrode and a second organic layer on the second electrode. The first organic layer is separated from the second organic layer by separator means. Further, the light-emitting diode matrix comprises a cap electrode with an area disposed on the first organic layer and an area disposed on the second organic layer. The areas of the cap electrode are connected in an electrically conductive way via an area of the cap electrode disposed on the separator means.

Abstract: The present invention relates to a method for inspecting the surfaces of a three-dimensional body (2), with which at least one camera and at least one illuminating device are moved relative to the surface of the object, pictures are taken of the areas of the surface to be inspected during the movement of the camera relative to the surface, and the pictures are transmitted to a computer (11) and are evaluated therein. The invention also relates to a corresponding system. In order to obtain high inspection quality, the camera, illumination device and the surface are brought into a defined geometric relationship with each other during the inspection of each area to be inspected on the surface, at least for the period of time required to take a picture.

Abstract: An illumination device has a plurality of main illumination areas subdivided into at least a first and a second sub-illumination area, wherein a luminous element for outputting radiation is arranged on each sub-illumination area, and wherein a beam deflection unit is associated with each main illumination area, which is designed to deflect the radiation output by the luminous element of the first sub-illumination area into another direction than the radiation output by the luminous element of the second sub-illumination area.

Abstract: An opto-electronic device includes a substrate, a light sensor and a light-emitting diode having a light-emitting layer of an organic material, wherein the light sensor and the light-emitting diode are monolithically integrated with the substrate.

Abstract: It is the knowledge of the present invention that the spectrum of any light emitting device can be converted into a desired spectrum in a simple way, by providing a light emitting device with a light conversion layer, which has a dye with a conversion property, to convert the light emitted by the light emitting device into light of a different spectrum, and thereupon acting upon the spectrum conversion layer such that the dye is at least partly removed or a conversion property is destroyed. In this way, it is also possible in a simple way to structure a display of a plurality of light emitting devices to a color display, by providing a spectrum conversion layer for all light emitting devices, i.e.
