Abstract
A light-emitting diode assembly having at least one light-emitting diode, a controller which is designed to dim the at least one light-emitting diode by means of pulse width modulation, wherein the pulse width modulation is characterized by a clock pulse and a pulse duration during a clock pulse. The controller is designed to actuate the at least one light-emitting diode with packets of at least two clock pulses. The controller being optionally designed to actuate the at least one light-emitting diode in a first operating mode and at least one second operating mode, wherein the at least one light-emitting diode is actuated in the first operating mode with the same pulse durations within the packet and is actuated in the second operating mode with at least one different pulse duration within the packet.
