Abstract: The subject of the invention is a reflector device for a lighting module of a motor vehicle. The device includes a housing made of plastic, wherein the internal faces are metallized so as to reflect the light received. The housing on an external face of one of its walls has reception means able to house a support including at least one light source, the wall having an opening which leads toward the inside of the housing and which allows the light emitted by the light source or sources to propagate toward the inside of the housing. According to the provisions of the invention, the external face of the housing may be connected to ground potential so as to act as a shield against the electromagnetic waves emitted by various electronic components.

Abstract: A design of a bridging connector, a connection assembly, a vehicle lamp, and a vehicle. The bridging connector is used to connect circuit board components arranged on a carrier, and the circuit board component is provided with electrical contact holes and has a board surface. The bridging connector includes a housing with contact surfaces and contact bodies arranged in the housing. In the installed state, the contact surfaces are in contact with the board surface, and the contact bodies are located in the electrical contact holes in a manner of being in contact with the electrical contact holes. The housing is provided with guide holes, and the guide holes cooperate with guide pins provided on the carrier so that the contact bodies occupy a predetermined position with respect to the electrical contact holes.

Abstract: A method for a driver device of an automotive lighting device that includes at least two inputs for receiving one electricity supply each, and a power converter circuit for selectively converting the electricity supplied on one of the inputs into a periodic power supply for powering said lighting device. The method allows for switching between inputs of the driver device while reducing the power supply shortage which generally arises at the time of switching inputs. This allows for providing generally flicker-free luminosity while using a single converter circuit.

Abstract: A converter that makes it possible to selectively switch between various converter architectures that are capable of supplying different output voltages on the basis of one and the same input voltage. The various architectures share at least some electronic components with one another, thereby decreasing the production cost of the converter according to the invention. The converter is particularly advantageous for lighting modules for motor vehicles, in which there are substantial space constraints but in which wide output-voltage ranges are required to be able to supply a varied and substantial number of electroluminescent light sources (LEDs) with power.

Abstract: The invention provides a device for driving the electrical power supply of at least one electronic circuit branch comprising at least one light source of an automotive vehicle. A converter circuit converts an input voltage VIN into a load voltage (or current) that is applied to said circuit branch, and control means are configured to control the converter circuit by means of a periodic PWM signal having a predetermined frequency f. The frequency f is adapted in real time and according to a disruption that is detected in the input voltage signal VIN in order to avoid any occurrence of flickering in the intensity of the luminous flux emitted by the light sources.

Abstract: A device that provides a circuit for controlling the power supply of a plurality of groups of light sources, preferably of the light-emitting diodes type, which perform a plurality of lighting functions for an automobile vehicle. The device is noteworthy in that it enables a primary output voltage and several high-voltage secondary outputs to be produced, corresponding to the power supply requirements of the various groups of light sources, with the use of a single switch-mode converter circuit.

Abstract: The invention proposes a light device casing formed by a wall made of an electrically insulating material, such as a polymer. The casing includes an inner surface forming a housing receiving a light module with a light-emitting diode and a light guide. The inner surface includes a zone reflecting light from the light module out of the casing, and a fixing zone for a control module of the light module. The light device includes a reflecting and electrically conductive coating, which covers both the reflecting zone and the fixing zone. The aluminum coating is cost-effective since it is applied in one step, and it ensures two functions, namely a reflection and a protection against the electromagnetic field.
