  • HEAT SINK DEVICE FOR A MOTOR VEHICLE LIGHTING MODULE
    Publication number: 20180252383
    Abstract: A heat sink device for a motor vehicle lighting module made of stamped aluminum and ensures good thermal conductivity. The arrangement of the cooling fins of the device is such that the device is able to be installed in various orientations, while at the same time ensuring good dissipation of the heat produced by a printed circuit board attached to the device.

  • STEP-UP/STEP-DOWN CONVERTER WITH A PROTECTIVE CIRCUIT
    Publication number: 20170111964
    Abstract: A device and a method for protecting the buck circuit of a DC voltage converter, for example of boost-buck type, if the input voltage of the boost circuit falls below a voltage threshold value. The invention finds a particular application in devices for controlling the power supply of light sources and notably light-emitting diodes (LED).

  • System for controlling the electrical power supply of a plurality of light sources using a multiphase converter
    Patent number: 9475425
    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.
