Abstract: An indicator light for a motor vehicle includes a divider screen adapted to divide a light beam into a plurality of elementary light beams which are then added together downstream of the dividing screen. A first coloring means, for coloring some of the elementary light beams, is located at a distance from the divider screen. The light unit includes a second coloring means adapted to color at least some of the elementary light beams, the second coloring means being spaced away from the divider screen and the first coloring means.

Abstract: An indicator light comprises a source, an optical plate adapted to straighten out the incident light towards an average direction generally parallel to an optical axis, and a flux-distributing and recuperating cup interposed between the source and the plate in order to distribute the light over the inner surface of the plate. According to the invention, the optical plate has a height and a width of the same order of magnitude and possesses optical configurations having varied coefficients of transmission of the light, and the cup provides a given distribution of the light, both in the horizontal direction and in the vertical direction, which takes account of said coefficients. As a result, an illumination is obtained at the exit from said plate which is essentially constant in the horizontal direction as well as in the vertical direction.

Abstract: In an assembly of at least one headlight and an indicator light for a motor vehicle, the headlight includes a lamp which is mounted in a reflector, and the indicator light, which is situated adjacent to the headlight, includes a lamp and reflective means for flux recuperation. The headlight and the indicator light also have adjacent lenses. The reflective means comprise a first reflector cooperating with the lamp of the indicator light, and a second reflector, the lamp and the first reflector of the indicator light being disposed behind the reflector of the headlight, and the second reflector of the indicator light is disposed in line with the lens of the indicator light.

Abstract: A rear indicating light for a motor vehicle comprises a light source, a bonnet in front of the light source, and an optical plate in front of the bonnet. The bonnet has means for distributing essentially uniformly the radiation it receives from the light source, over at least part of the surface of the flat optical plate, which is formed with striations to align the radiation along the optical axis. These striations are grouped in at least one discrete zone on the surface of the plate, the remainder of this surface consisting of at least one optically neutral zone, while the distributing means are adapted to distribute at least some of the radiation from the light source towards the discrete striated zones.

Abstract: A motor vehicle indicating light unit comprises a light source, an optical plate having optical arrangements to redirect the light from the region of the source so that it propagates with a mean direction generally parallel to a horizontal optical axis and a flux recovery and distributor bonnet disposed between the source and the optical plate. The bonnet assures a given distribution of the light onto the inside surface of the optical plate in at least a given direction. The optical plate is curved and has optical arrangements having different light transmission coefficients. The bonnet assures the given distribution of light which allows for the different transmission coefficients to obtain an evolution of the illumination at the exit from the plate in the given direction that satisfies a predetermined law.

Abstract: An indicating light display for a motor vehicle, and in particular a raised stop light in the form of a strip which contains a plurality of light sources, also includes optical processing means for redirecting the light received from the light sources so that it will be propagated in the general emission direction. The display thus consists of a series of light cells, each defining a transition zone between each cell and the next. The optical processing means include, in association with each light source, a first element for distributing the light, in a plane at right angles to the general emission direction, on a second element in the form of an optical plate. This optical plate is divided into zones each associated with one of the cells and formed with projecting striations. Each transition between a zone and the next zone is formed with a transition striation which receive light from both of the two adjacent light sources and redirects this towards the general emission direction.
