Abstract

Dispositif lumineux bi-fonction avec lentille rotative L’invention a trait à un dispositif lumineux (2) pour véhicule automobile, comprenant au moins une source lumineuse (6) apte à émettre des rayons lumineux ; au moins un collecteur (20) avec une surface réfléchissante (8) configurée pour collecter et réfléchir les rayons lumineux émis par l’au moins une source lumineuse (6) en un faisceau lumineux suivant ; un système optique (10) comprenant une fonction de lentille et configurée pour projeter le faisceau lumineux en imageant une partie de l’au moins une surface réfléchissante (8) située à l’arrière de l’au moins source lumineuse correspondante (6) ; où la fonction de lentille est une première fonction, le système optique (10) comprenant une deuxième fonction optique, ledit système optique étant rotatif autour d’un axe de rotation (14) entre une première position où la première fonction est active et une deuxième position où la deuxième fonction est active. (Figure à publier avec l'abrégé : Figure 2)Bi-function light device with rotating lens The invention relates to a light device (2) for a motor vehicle, comprising at least one light source (6) capable of emitting light rays; at least one collector (20) with a reflective surface (8) configured to collect and reflect the light rays emitted by the at least one light source (6) into a subsequent light beam; an optical system (10) comprising a lens function and configured to project the light beam by imaging a part of the at least one reflective surface (8) located behind the at least corresponding light source (6); wherein the lens function is a first function, the optical system (10) comprising a second optical function, said optical system being rotatable about an axis of rotation (14) between a first position where the first function is active and a second position where the second function is active.
