  • Patent number: 8282998
    Abstract: The present invention relates to a method of realizing an optical function on a component of a motor vehicle indicating or lighting device. This method is more particularly suited to producing a mask for a headlamp or light and/or to treating reflective surfaces. The method comprises a step of forming said component in a predetermined material and a step of exposing at least one surface of said component to laser radiation.
    Type: Grant

  • Patent number: 7018056
    Abstract: The present invention concerns a method of producing a lighting or signalling device comprising a light source (16), a reflector (14) reflecting the light rays emitted by the light source (16) towards a lens (18) so as to form along an optical axis (A—A) alighting or signalling beam, the lens (18) comprising a peripheral flange (24) and being held by a support (20), the support (20) comprising an annular surface (26, 26?) limited at its external periphery by a cylindrical rim (28, 34). According to the present invention, the method comprises the step consisting of deforming the cylindrical rim (28, 34) in the direction of the annular surface (26, 26?) in order to envelop the peripheral flange (24) of the lens (18) and hold it in place without play and without requiring an additional component, this deformation of the cylindrical rim (28, 34) being performed by applying on this rim a force parallel to the optical axis (A—A) of the lighting or signalling device.

  • Patent number: 6783268
    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.

  • Publication number: 20030123260
    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).
