More Information
Summary:Disclosed is a control device (5) for an illumination device (3) of a motor vehicle (1), said illumination device (3) comprising at least one LED (4) and being especially a daytime running light and/or a parking light. The control device (5) comprises a converter (7) and a control unit (8) for controlling the converter (7) in accordance with a control signal, the brightness of the illumination device (3) being adjusted by having the control unit (8) control the converter (7) in a pulse width-modulated manner in accordance with a sampling degree of the control signal. According to the invention, a characteristic curve (13) which transforms a sampling degree of the control signal into a sampling degree of the converter (7) is stored in the control unit (8), at least a range (14) of the sampling degree of the control signal lying below a threshold value (15) being transformed into a zero sampling degree for the converter (7).
