Abstract: A luminous motor-vehicle system including an optical module and aims to compensate for undesirable movement or deformation effects caused by the manufacturing tolerances of the optical portion. The module includes an imaging device provided with a pixelated spatial modulator, which is illuminated by a source, and a projecting optic. A control unit for controlling the modulator receives first display commands that are representative of an image to be projected. This unit converts each first display command into a second display command taking into account correction parameters, which are predefined on the basis of an identification of geometric defects specific to the projecting optic. The control unit controls the modulator, which may be a digital micromirror device, depending on the second display commands in order that the image actually projected by the imaging device corresponds to the image to be projected.

Abstract: The present invention relates to a lighting system including a primary light source producing a primary light beam in the direction of a conversion device that returns a secondary light radiation to an optical imaging system forming a projected light beam. A light sensor generates a signal corresponding to the light received by this sensor. The light includes a non-converted light part of the first primary light beam which is returned by the conversion device in the projected light beam and is reflected by an obstacle situated in the zone illustrated by said projected light beam. A control unit has modulation means generating a modulation signal for the primary light, and demodulation means for processing the signal formed by said sensor, and determines a distance between the obstacle and the lighting system.

Abstract: A light device including a light source driven to produce the emission of light rays, as well as a deflection element arranged facing the light source to deflect the emitted light rays, and a ray-forming optic for emitting a light beam out of the device. The light source is a semiconductor source, including at least one substrate and a plurality of light-emitting elements of submillimetric dimensions which extend from a first face of the substrate. The deflection element takes the form of an elliptical or pseudo-elliptical reflector, whose inner face forms a reflection face for the emitted light rays which is turned towards the first face of the substrate of the light source. Also, the forming optic is a divergent lens.
