  • Device for controlling power supply towards light sources and related method
    Patent number: 8749170
    Abstract: In various embodiments, a device for controlling power supply towards at least one light source comprising a load having a value variable as a result of switching of at least one switch coupled thereto, is provided. The device may include: a power supply set controllable to determine the intensity of the current fed towards said load; a current feedback loop sensitive to the intensity of the current fed towards said load, said current feedback loop connected to said power supply set to maintain the intensity of the current fed towards said load upon variation of said load; and a voltage control sensitive to the voltage across said load, said voltage control likewise connected to said power supply set to maintain the intensity of the current fed towards said load upon variation of said load.
