Abstract: An optoelectronic semiconductor device includes a semiconductor layer sequence including an active zone that generates radiation by electroluminescence; a p-electrode and an n-electrode; an electrically insulating passivation layer on side surfaces of the semiconductor layer sequence; and an edge field generating device on the side surfaces on a side of the passivation layer facing away from the semiconductor layer sequence at the active zone, wherein the edge field generating device is configured to generate an electric field at least temporarily in an edge region of the active zone so that, during operation, a current flow through the semiconductor layer sequence is controllable in the edge region.

Abstract: In an embodiment, an optoelectronic semiconductor component includes a semiconductor layer sequence with a doped first layer, a doped second layer, an active zone configured to generate radiation by electroluminescence between the first layer and the second layer, and a side surface extending transversely to the active zone and delimiting the semiconductor layer sequence in a lateral direction, two electrodes for electrical contact between the first and second layers and a cover layer located on the side surface in a region of the first layer, wherein the cover layer is in direct contact with the first layer, wherein a material of the cover layer alone and its direct contact with the first layer are configured to cause a formation of a depletion zone in the first layer, wherein the depletion zone comprises a lower concentration of majority charge carriers compared to a rest of the first layer, wherein the cover layer comprises a metal or a metal compound, and wherein the cover layer forms a Schottky contact with the first layer.

Abstract: A method for operating a light emitting diode arrangement with at least one light emitting diode includes the steps of: a) determining at least one instantaneous current-voltage value pair; b) matching the instantaneous current-voltage value pair with an original current-voltage value pair; and c) determining an updated current feed based on the matching and driving the light emitting diode with the updated current feed.

Abstract: An optoelectronic semiconductor component comprising a connection carrier with a mounting face and an electrically insulating base member. An optoelectronic semiconductor chip is arranged on the mounting face of the connection carrier. A radiation-transmissive body having four side faces is provided. The radiation-transmissive body surrounds the semiconductor chip in such a way that the radiation-transmissive body envelops outer faces of the optoelectronic semiconductor chip not facing the connection carrier in form-fitting manner. The radiation-transmissive body comprises at least one side face which extends at least in places at an angle of between 60° and 70° to the mounting face. The base member has a thickness which amounts to at most 250 μm.
