  • Patent number: 10507759
    Abstract: An adaptive lighting system for an automotive vehicle. The adaptive lighting system has a wavelength conversion device for receiving the light radiation (L) from the primary source and re-emitting white light radiation (B). An optical imaging system receives the white light (B) re-emitted by the wavelength conversion device and projects this light (B) in front of the vehicle to form a lighting beam, the wavelength conversion device being situated close to a focal plane of the optical imaging system, and the scanning system and the optical system being situated on the same side or on opposite sides of the wavelength conversion device. An intensity of the white light radiation (B) emitted by the wavelength conversion device is capable of being modulated between a minimum value and a maximum value, and the scanning is performed at variable speed.

  • Patent number: 7252420
    Abstract: The object of the invention is a lighting device for a motor vehicle, comprising a first light source focused on a first reflective zone and a second light source focused on second reflective zone. The first light source is able to emit light both in the direction of the first reflective zone and part of the second reflective zone, the light coming from the light source and reflected by the two reflective zones corresponding to a DRL daylight light beam.

  • Patent number: 7252417
    Abstract: The bonding light and dipped beam headlamp for a motor vehicle comprises at least two light sources with at least one first source having a cut-off of the dipped beam type and at least one second source having a cut-off of the flat type, which is placed outside the first source so as to illuminate into a turn to its side; means that are sensitive to the trajectory of the vehicle so as to supply a signal that depends on the nature of the route followed by the vehicle; and means for increasing the brightness of the flat cut-off source in the event of a turn to the side of this source, in response to the supplied signal.

  • Patent number: 6354722
    Abstract: A vehicle headlight has a cam mechanism for displacing the reflector and the light source of the headlight with respect to each other, between two relative positions in which the headlight emits two different types of light beam. The cam mechanism comprises a first cam member and a second cam member, and it converts rotation of the first cam member about an axis of rotation into a first straight line motion of the second cam member. The first straight line motion is collinear with the axis of rotation.

  • Patent number: 5933084
    Abstract: An indicator light for a motor vehicle includes a light source and a reflector, which directs light from the light source in a forward direction on a first screen having lines of optical elements, which converge the light beam received from the reflector on a second screen in front of the first screen. The second screen includes, through at least part of its thickness, colored bands and translucent bands which are arranged alternately with each other over the height of the screen. In the first screen, the lines of optical elements are separated from each other by opaque colored bands, which are aligned with the colored bands of the second screen.
