Abstract

L’invention concerne un dispositif lumineux (300), tel qu’un pour véhicule automobile, comprenant au moins un module d’éclairage (301.1;301.2) apte à projeter des rayons lumineux pour réaliser une fonction d’éclairage et comprenant en outre un module lumineux (400; 500; 600) comprenant une nappe de guidage flexible apte à recevoir des rayons lumineux et à les renvoyer dans une direction sensiblement normale à une surface de la nappe de guidage flexible, au moins un élément d’injection de lumière apte à recevoir de la lumière et à distribuer la lumière dans la nappe de guidage flexible et au moins une source de lumière apte à injecter de la lumière dans l’élément d’injection de lumière. Le module lumineux est agencé de manière à ce que la nappe de guidage flexible soit traversée par les rayons lumineux issus du module d’éclairage et la source de lumière est activée lorsque le module d’éclairage est désactivé.
