Abstract

La présente invention se rapporte un dispositif lumineux de véhicule comprenant : - une source lumineuse à bâtonnets électroluminescents de dimensions submillimétriques, l'ensemble de ces bâtonnets étant répartis en plusieurs zones lumineuses distinctes (1 à 3), au moins une zone lumineuse étant agencée de manière à émettre une couleur différente de celle émise par au moins une autre zone lumineuse, - au moins une optique, apte à recevoir les rayons lumineux émis par les zones lumineuses et à les dévier hors du dispositif lumineux, la source lumineuse et l'optique étant agencées de manière à former un faisceau lumineux et à être apte à conférer à ce faisceau lumineux plusieurs couleurs différentes.The present invention relates to a vehicle light device comprising: a light source with electroluminescent rods of submillimetric dimensions, all of these rods being distributed in several distinct light zones (1 to 3), at least one light zone being arranged of in order to emit a color different from that emitted by at least one other light zone, - at least one optic, able to receive the light rays emitted by the light zones and to deflect them out of the light device, the light source and the optics being arranged so as to form a light beam and to be able to give this light beam several different colors.
