摘要：
A device and method for controlling the supply of power to light sources, in which a DC/DC converter is capable of delivering a voltage VMAX to the light sources. The forward voltage of the light sources depends on temperature and may temporarily exceed VMAX at low temperatures. The invention proposes means that allow the required forward voltage to be decreased automatically depending on a measurement of ambient temperature.
