Abstract
A circuit arrangement is disclosed for controlling an illuminating device, particularly light-emitting diodes, in a control device of a motor vehicle, comprised of at least one illuminating device, which is integrated in a switching circuit having a semiconductor component, and of a microprocessor, in particular having an integrated non-volatile memory, for generating a pulse-width modulated signal, whereby the pulse-width modulated signal is coupled to a control electrode of the semiconductor component, whereby the microprocessor generates at least two pulse-width modulated signals, the pulse-width modulated signals are coupled to the semiconductor component via a logical system and the logical system can be subjected to the action of an additional control signal via the microcomputer.
