Abstract
A control device for an illuminant having at least two semiconductor light sources and connectable to an electrical energy source, for converting an electrical power provided by the electrical energy source, by the semiconductor light sources, into an emitted light power dependent on the electrical power provided is disclosed. The semiconductor light sources are connected to the control device, and the control device is designed to set the electrical power provided by virtue of the control device including a clock generator designed to apply electrical power to the semiconductor light sources in clocked operation and to control said semiconductor light sources in accordance with clock pulse sequences individually assigned to the semiconductor light sources. The clock generator is designed to form a common pulse pattern from the clock pulse sequences and to set the light power emitted by the illuminant by selecting a pulse pattern assigned to the light power.
