Abstract

L’invention concerne un module lumineux (500) comprenant un ensemble d’au moins une nappe de guidage flexible (510.1; 510.2), chaque nappe de guidage flexible de l’ensemble étant apte à recevoir des rayons lumineux par un bord de ladite nappe de guidage flexible et à renvoyer les rayons lumineux dans une direction sensiblement normale à une surface de la nappe de guidage flexible selon au moins un motif gravé dans ladite nappe de guidage flexible, dans lequel l’ensemble étant apte à renvoyer de la lumière selon un premier motif et un deuxième motif. Le module comprend un premier et un deuxième éléments d’injection de lumière (520.1; 520.2) aptes à distribuer de la lumière dans l’ensemble d’au moins une nappe de guidage flexible. Au moins une source de lumière (530.1; 530.2) est apte à injecter sélectivement de la lumière dans les premier et deuxième éléments d’injection de lumière de manière à former le premier motif ou le deuxième motif.
