Abstract: The invention relates to an optoelectronic component (100) comprising a semiconductor layer sequence (1) having an active layer (10), wherein the active layer (10) is designed to produce or absorb electromagnetic radiation in intended operation. Furthermore, the component (100) comprises a first contact structure (11) and a second structure (12), by means of which the semiconductor layer sequence (1) can be electrically contacted in intended operation. In operation, a voltage is applied to the contact structures (11, 12), wherein an operation-related voltage difference ΔUbet between the contact structures (11, 12) arises. When the voltage difference is increased, a first arc-over occurs in or on the component (100) between the two contact structures (11, 12). A spark gap (3) between the contact structures (11, 12), which arises in the event of the first arc-over, passes predominantly through a surrounding medium in the form of gas or vacuum and/or through a potting. The first arc-over occurs at a voltage difference of 2·ΔUbet at the earliest.

Abstract: An optoelectronic component that emits electromagnetic radiation from a radiation exit surface of the optoelectronic component includes a radiation-emitting semiconductor chip that produces electromagnetic radiation, and a marker element applied to the radiation exit surface of the optoelectronic component, the marker element including a dye substance that can be removed from the radiation exit surface using a solvent and/or is permeable to the electromagnetic radiation of the optoelectronic component, wherein the dye substance includes a resin into which fluorescent particles are introduced that convert electromagnetic radiation of a first wavelength range into electromagnetic radiation of a second wavelength range, the first wavelength range and the second wavelength range being within the ultraviolet spectral range.
