Abstract
A method for operating an optoelectronic assembly which includes at least one component string having at least one section, wherein the section includes at least one light emitting diode element, is provided. According to the method, the component string is supplied with electrical energy, the supply of the component string with electrical energy is interrupted, a total voltage is detected, which is present between an input and an output of the section of the component string, the total voltage is compared with a sum of threshold voltages of all the light emitting diode elements. It is identified that the section has no short circuit if the total voltage is equal or at least approximately equal to the sum of the threshold voltages, and/or it is identified that the section has a short circuit if the total voltage is less than the sum of the threshold voltages.
