Abstract: The invention proposes an indicator lamp comprising an optical axis oriented from the rear to the front, on which there is a light source which is provided for emitting a light flux towards the front, and of the type comprising an optical device for recovering and distributing the rays of light emitted by the source, with a view to providing an indicating faction that meets the regulations, wherein the optical device comprises a coaxial annular reflector and, in front of the light source a central optical part known as the light engine which is provided for distributing the rays of light emitted by the source in directions that are generally transverse about the optical axis, towards the coaxial annular reflector that is provided for distributing the rays of light axially towards the front.

Abstract: An apparatus for lighting or indicating purposes in a motor vehicle includes a light guide associated with at least one light source for transporting light rays emitted by the light source from an input face to an output face via and intermediate section of the light guide. The output face of the light guide is contained between two closed lines which define a continuous internal contour and a continuous external contour, and the input face is contained between two further closed lines, also delimiting continuous internal and external contours.

Abstract: The invention proposes an indicator light, in particular for a motor vehicle, of the type comprising a central optical axis oriented from rear to front, a light source on this optical axis, and a solid optical piece, of the type in which the optical piece comprises an input surface and an output surface,

Abstract: An indicator lamp for a motor vehicle includes a plurality of light sources, and a plurality of linking elements. The lamp includes components that straighten out the light emitted by the light sources so that the light is propagated in a direction essentially parallel to a general direction of emisssion. These components include multiple first elements and a second element. East first element corresponds to one of the plurality of light sources. The first elements are able to distribute the light in a plane essentially perpendicular to the general direction of emission, in an essentially uniform way onto the second element. The second element is able to straighten out the incident light towards the general direction of emission.

Abstract: The invention proposes an indicator lamp (10), comprising an optical axis (A-A) oriented from the rear to the front, on which there is a light source (14) which is provided for emitting a light flux towards the front, and of the type comprising an optical device for recovering and distributing the rays of light emitted by the source, with a view to providing an indicating function that meets the regulations, characterized in that the optical device comprises a coaxial annular reflector and, in front of the light source (14), a central optical part known as the light engine (22) which is provided for distributing the rays of light emitted by the source (14) in directions that are generally transverse about the optical axis (A-A), towards the coaxial annular reflector that is provided for distributing the rays of light axially towards the front.

Abstract: The present invention relates to an indicator lamp for a motor vehicle comprising a plurality of light sources (10) and optical processing means (16, 18, 20) able to straighten out the light emitted by the light sources (10) so that it is propagated in a direction essentially parallel to a general direction of emission (X), the optical processing means (16, 18, 20) comprising, in association with each source (10), a first element (12, 16, 18) able to distribute the light in a plane (YZ) essentially perpendicular to the general direction of emission (X), in an essentially uniform way onto a second, generally plate-shaped, element (14, 20) able to straighten out the incident light towards the said general direction of emission (X).

Abstract: A motor vehicle indicator light has an elongate light source, highly inclined with respect to a required beam spread direction and a reflector in which the source is mounted. The reflector includes a mirror able to create, from part of the source situated opposite it, a primary virtual light source parallel to the required direction of spread and means for concentrating the light radiation coming from the said primary virtual source in the vicinity of a plane containing the required beam spread direction.

Abstract: A motor vehicle headlamp has a discharge lamp, a reflector and a smooth or nearly smooth cover lens, the reflector being adapted to generate a beam below a cut-off line. At least two masks are associated with the discharge lamp, and define two shadow zones on the reflector; the reflector includes at least two reflective zones for forming portions of the beam below the cut-off line, with different amounts of sideways spreading of the light; and these zones of the reflector are separated by generally radial transition planes, at least some of which extend into the shadow zones. A particular application is to enable wide cruising beams to be produced to European standards without any optical anomalies.
