Abstract

L’invention concerne un dispositif lumineux (1) de véhicule comportant un guide de lumière (6) transparent ou translucide, et une source lumineuse (8A) disposée à une extrémité ou à un bord du guide de lumière (6), le guide de lumière (6) comprenant un cœur (10), la source lumineuse (8A) émettant un faisceau de lumière blanche dans le cœur (10) du guide de lumière. Selon l’invention, le guide de lumière (6) comporte une structure multicouche (12) accolée au cœur (10) et comprenant un substrat (14), une couche réfléchissante (16), et une couche de matériau organique électrochrome (18) structurée en une pluralité d’éléments (E1, E2, …E9), chaque élément étant encapsulé dans une couche d’électrolyte et étant connecté à une paire d’électrodes apte à recevoir une tension électrique, et le dispositif lumineux (1) comporte en outre un circuit électrique de commande (4) configuré pour piloter la tension électrique aux bornes de chaque paire d’électrodes.
