Abstract
A device and a method for controlling the electrical power supply of a plurality of light sources, preferably of light-emitting diodes, or LEDs. The plurality of light sources is divided into at least two groups of light sources. The invention is noteworthy in that it allows the use of a multiphase step-up voltage converter for all the groups of light sources, whereas the measurements of the input currents for each of the phases of the converter give a reliable indication of the level of power required by one of the groups being powered.
