Patent number: 10697602Abstract: A lighting device for motor vehicles including at least one first light source that is centered on and/or aligned with the optical axis of a projection lens of the lighting device, and a diaphragm element in order to form a cut-off profile in a first light beam shaped by the projection lens. This advantageous configuration enables reduction of chromatic defects linked to interaction between the diaphragm element and light rays generated by the first light source. The lighting device advantageously includes a second light source in order to be able, in collaboration with the first light source, to generate a second light beam. In this case, the diaphragm element is advantageously inclined on the second light source side relative to the optical axis of the projection lens.Type: GrantFiled: December 20, 2018Date of Patent: June 30, 2020Assignee: Valeo VisionInventors: Adrien Manassero, David Bourdin

Patent number: 10267477Abstract: A lighting module for a motor vehicle includes a first light source and a first collimator for generating a first light beam of “low beam” type in collaboration with a first projection lens. Also included are second and a third light sources, the second light source collaborating with a second collimator to generate a first beam complementing the first light beam in order to form a second light beam of “high beam” type. In order to reduce the visibility of a cut-off zone in the second beam, the third light source collaborates with a third collimator and/or a second projection lens in order to form a second complementary beam which at least partly overlaps the cut-off zone. A front headlight for a motor vehicle can include such a lighting module.Type: GrantFiled: February 1, 2018Date of Patent: April 23, 2019Assignee: VALEO VISIONInventors: Orane Marchal, David Bourdin, Stephane Andre, Fabrice Mairet, Sergio Donoso, Ran Fujita

Patent number: 10190741Abstract: Lens for a lighting device of a motor vehicle includes a rear face designed to be oriented toward a light source of the lighting device, and a convex front face designed to be oriented toward the roadway being illuminated. The lens has a median vertical plane designed to be substantially orthogonal to the roadway, the front face having a first zone of diffusion with microstructures adapted to diffuse the light emitted by the light source, the first zone of diffusion extending in the median vertical plane. The front face furthermore includes at least two second zones of diffusion each one having microstructures adapted to diffuse the light emitted by the light source, the two second zones of diffusion being situated on either side of the median vertical plane. The microstructures of the two zones of diffusion have a depth absolutely greater than the depth of the microstructures of the first zone of diffusion.Type: GrantFiled: March 1, 2017Date of Patent: January 29, 2019Assignee: VALEO VISIONInventors: Marie Pellarin, David Bourdin, Stephane Andre

Patent number: 8459849Abstract: An optical device having an optical axis (y-y) and comprising a source of light; a reflector which is associated with the source of light in order to form a light beam; and a rotary assembly which is designed to intercept the light beam, and can be rotated around an axis of rotation between first and second distinctive lighting positions. The rotary assembly comprises at least first and second shields associated respectively with the first and second lighting positions, in order to create a cut-off of the light beam. The first and second shields each comprise at least one ridge. The rotary assembly additionally is designed to permit progressive transition of the lighting between the first and second distinctive lighting positions.Type: GrantFiled: April 23, 2010Date of Patent: June 11, 2013Assignee: Valeo VisionInventors: Martin Grimm, Stephane Thery, Alice Mulin, David Bourdin, Jonathan Blandin, Jean Masse

Patent number: 8348485Abstract: A headlamp for a motor vehicle, this headlamp comprising at least one optical module capable of emitting a plurality of light beams, including a low beam and at least one additional light beam. The optical module is equipped with a cover plate which can be moved between at least two positions, this movable cover plate being configured along a shaft mounted so as to rotate in the optical module and driven in rotation at least by a motor. The shaft comprises at least one first cut-off member configured as a double-edged cover plate providing an oblique cut-off for emission of the low beam, and at least one second cut-off member configured as a wall of substantially constant height, angularly offset relative to the first cut-off member and providing at least one substantially vertical cut-off line for emission of a high beam.Type: GrantFiled: September 30, 2009Date of Patent: January 8, 2013Assignee: Valeo VisionInventors: Pierre Albou, Jonathan Blandin, David Bourdin, Jean-François Le Bars, Boris Wiegand

Patent number: 7708434Abstract: A proposed method to illuminate optimally, or at least in an improved fashion compared with existing solutions, a road taken by a vehicle in question implementing the method whilst ensuring that other vehicles are not dazzled. To this end, it is not proposed in the invention to detect the distance between the vehicle in question and the first vehicle liable to be dazzled by the vehicle in question, and to generate accordingly a light beam optimized in terms of range on the road, and advantageously light intensity; according to the invention, the optimization of the light beam produced is achieved by the use of the motorway function available on the vehicle in question. The use of this function in this context also ensures a gradual transition between the function of the dipped type and the function of the main-beam type in the context of automatic switching operations between these functions.Type: GrantFiled: November 16, 2007Date of Patent: May 4, 2010Assignee: Valeo VisionInventors: Julien Moizard, Benoît Reiss, Pierre Albou, David Bourdin
