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.
