Abstract:
An indicator light for a motor vehicle comprising a light source, an optical plate having optical configurations adapted to straighten out the lighting originating from a region of the source so that it is propagated with an average direction generally parallel to a horizontal optical axis, and a flux-distributing and recuperating cup interposed between the source and the optical plate and adapted to provide a given distribution of the light over the inner surface of the optical plate in at least one given direction, wherein the optical plate has a height and a width of the same order of magnitude and possesses optical configurations exhibiting coefficients of transmission of the light which are different from one another, and wherein the cup provides a given distribution of the light, both in the horizontal direction and in the vertical direction, which takes account of said different transmissions coefficients so as to obtain an illumination at the exit from said plate which is essentially constant in the horizontal direction as well as in the vertical direction.
