Abstract
A circuit for operating a light-emitting diode assembly, wherein the light-emitting diode assembly comprises a plurality of strands connected in parallel of one or more light-emitting diodes which are arranged in series and through which in the operational state a particular partial current of an operating current flowing through the light-emitting diode assembly flows, comprises a current source for providing the operating current. The circuit is designed to detect the greatest partial current and to control an operational value provided by the partial current source on the basis of said greatest partial current such that none of the partial currents exceeds a predetermined maximum current.
