Abstract

The invention discloses an optoelectronic assembly and a method for operating an optoelectronic assembly. The invention relates to an optoelectronic assembly (100, 200, 300, 500, 700, 800) in various embodiments. The optoelectronic assembly (100, 200, 300, 500, 700, 800) comprises at least one optoelectronic component (180) and a sensor circuit (170), which comprises at least one energy supply circuit (160) and a determination circuit (130), which has at least an energy storage unit (132) and a sensing unit (134), wherein the determination circuit (130) and the at least one optoelectronic component (150) are electrically connected in parallel with each other; wherein the at least one energy supply circuit (160) is designed to supply electrical energy to the at least one optoelectronic component (180) and the energy storage unit (132), wherein the energy stored in the energy storage unit (132) is supplied independently of the electrical energy supplied to the at least one optoelectronic component (180); and wherein the determination circuit (130) is designed in such a way that the sensing unit (134) senses a change in the electrical energy stored in the energy storage unit (132) according to a change in the energy stored in the at least one optoelectronic component (180).

Description

technical field [0001] The invention relates to an optoelectronic component and a method for operating an optoelectronic component. Background technique [0002] An optoelectronic component can have, for example, one, two or more light-emitting diode elements. The light-emitting diode element can be, for example, a light-emitting diode (LED) and / or an organic light-emitting diode (OLED) or a part or section of a light-emitting diode (LED) or an organic light-emitting diode (OLED). [0003] Despite extensive quality control of the light-emitting diode components, it cannot be completely ruled out that the light-emitting diode components fail spontaneously during use. A typical error formation of a spontaneous failure, for example in the case of OLEDs, is a short circuit (English: Short) between the electrodes of the corresponding light-emitting diode element. A short circuit of the electrodes of the LED element inherently short-circuits, or discharges, the parasitic capacit...
