Abstract: A method for controlling a pixelated light source which includes a plurality of pixels. Following the receipt of a command to transition from an initial beam to a target beam, a target luminosity based on the target beam is defined for each pixel of the pixelated light source. The pixels of the light source are then grouped into at least two groups of pixels and the method includes successively driving the groups of pixels. Driving a group of pixels includes modifying the luminosity of each pixel of the group, from an initial luminosity to the target luminosity of the pixel.

Abstract: An optical module of a lighting system of a motor vehicle includes a light source, a primary optical system including at least two optical members, each optical member being arranged to form an image from the light source. The image is shifted with respect to the image formed by each other optical member from the light source. An optical projection system is arranged to project onto the ground the image formed by each optical member of the primary optical system from the light source.

Abstract: A motor vehicle lighting system includes a light source, a multi-phase interleaved power converter having a plurality of selectively activatable elementary converters, each of which is configured to generate an electrical signal having its own phase. The power converter is designed to supply electrical power to the light source, and controller is designed to selectively control each of the elementary converters of the power converter. The controller is designed to receive an emission command for the emission of a desired light beam by the light source and to activate a strictly necessary number of elementary converters of the power converter such that the power converter supplies, to the light source, an electrical power needed to emit the desired light beam.

Abstract: A light guide designed to be mounted in a vehicle includes a coupling portion presenting an input face, a main portion adjacent to said coupling portion, and a light output surface extending at least along the main portion. The light guide is arranged in such a way that light rays that enter into the light guide through the input face are propagated by total internal reflection along the coupling portion and then along the main portion, before reaching out of the light guide trough the output surface. The light input face is flat and has a periphery that is formed by only five edges of substantially the same size, these edges joining together such that they form five angles with substantially the same value.
