Abstract

L'invention concerne un système optique comportant : - une source lumineuse (100) prévue pour émettre un faisceau lumineux (F1), - un guide de lumière (200) comprenant une première (210) et une deuxième (220) branche comportant chacune une entrée (211, 221), lesdites branches se rejoignant en une troisième branche (230), - un moyen (300) prévu pour diriger ledit faisceau lumineux vers l'entrée de la première branche et/ou vers l'entrée de la deuxième branche, - au moins un moyen pour modifier une couleur et/ou une intensité d'un faisceau lumineux lorsqu'il est transmis à l'entrée de la première et/ou de la deuxième branche, de façon à émettre ledit faisceau lumineux dans au moins deux couleurs différentes (F23), en sortie de ladite troisième branche. Elle concerne également un dispositif d'éclairage et/ou de signalisation pour véhicule comportant un tel système optique.The invention relates to an optical system comprising: - a light source (100) intended to emit a light beam (F1), - a light guide (200) comprising a first (210) and a second (220) branch each comprising a input (211, 221), said branches joining in a third branch (230), - means (300) provided for directing said light beam towards the inlet of the first branch and / or towards the entrance of the second branch at least one means for modifying a color and / or an intensity of a light beam when it is transmitted to the input of the first and / or second branch, so as to emit said light beam in at least two different colors (F23) at the output of said third branch. It also relates to a lighting and / or signaling device for a vehicle comprising such an optical system.
