A light unit or indicating device for a vehicle (.e.g., a vehicle lighting unit, a vehicle indicating unit, reversing radars and other systems) has a shell, a light contained in the shell, and an electronics card mechanically associated with the shell. The electronics card is connected an electrical power supply and to a multiplexed bus of an on-board network. The card has a controller for the light that allows exchange of commands and information on status of the light unit over the multiplexed bus, and also has an internal bus connected to the controller and the light that allows exchange between them of commands generated by the controller and of the status information of the light unit. The unit may also have an ancillary component for implementing ancillary facilities such as light beam adaptation or automatic adjustment of the orientation of the light beam.

Lighting or indicating light unit for a vehicle and lighting or indicating system equipped with at least one such light unit

Driving assistance device for a motor vehicle, including at least one emitter of radiation toward the front of the vehicle, a receiver of part of this radiation reflected by a target vehicle, and control and calculation means for influencing the acceleration and braking of the following vehicle in accordance with information coming from the unit comprising the emitter and the receiver and in accordance with data pertaining to the following vehicle. At least the emitter is mounted so as to be rotatable in terms of the azimuth and means for driving the emitter in rotation are provided in order to modify the azimuth of the beam of the emitter in accordance with the curvature of the road. This beam advantageously turns by the same angle as that of the beam of an adaptive lighting system.

Motor-vehicle driving assistance device which is optimized by synergy with an adaptive lighting system

A motor vehicle headlight has a reflector with two focal regions, a light source in one of these focal regions producing a pool of reflected light in the other focal region, and a lens which converts the pool of light into a beam projected on the road. The headlight includes means for displacing the light source with respect to the reflector.

Elliptical headlight with beam modification by movement of optical elements

A motor vehicle headlight comprises a mirror having mounted therein a discharge lamp, a mask placed in front of the lamp, and a shielding plate of conductive material extending behind the mirror. The mask is made of conductive material and is connected to a fixed potential to capture the parasitic electromagnetic fields emitted forwards from the lamp. According to the invention, the shielding plate is constituted by a cover extending behind and along the mirror and connected to said fixed potential. The invention is applicable to ensuring electromagnetic compatibility for discharge lamp headlights.
