Abstract
A controller controls an illumination device of a motor vehicle including at least one light source. The controller includes at least one first stage that provides electric energy for supplying power to the illumination device. At least one second stage forwards the electric energy to the light source. The first stage includes intelligence for controlling the illuminating device, a first supplier for supplying the illumination device with control signals, a generator for generating a constant intermediate voltage, and a second supplier for supplying the second stage with the intermediate voltage. The second stage includes a converter for conversion of the intermediate voltage into a supply voltage suitable for supplying the power to the light source, a third supplier for supplying the light source with the supply voltage, and a mechanism for controlling the light source in dependency on the control signals. Also, an illumination device for a motor vehicle includes the controller.
