Abstract

Titre : Dispositif d’éclairage et de signalisation pour un véhicule automobile. La présente invention a pour principal objet un dispositif d’éclairage et de signalisation (1) comprenant au moins un module lumineux (4) apte à générer un faisceau d’éclairage (A) le long d’un axe optique longitudinal et un élément optique (2) à travers lequel le faisceau d’éclairage (A) est projeté, remarquable en ce que le dispositif d’éclairage et de signalisation (1) comprend un écran à cristaux liquides pilotable (18) plaqué contre l’élément optique (2), l’écran à cristaux liquides pilotable (18) étant apte à prendre des états de diffusion différents dont au moins un état de projection du faisceau d’éclairage (A) dans lequel l’écran à cristaux liquides pilotable (18) est transparent et un état d’émission d’un faisceau de signalisation dans lequel l’écran à cristaux liquides pilotable (18) est au moins partiellement diffusant. Figure 1.
