Abstract

L’invention concerne un module lumineux (300) comprenant au moins deux nappes de guidage flexibles (310.1; 310.2), chaque nappe étant apte à renvoyer des rayons lumineux selon un motif gravé. Un premier élément d’injection de lumière (320.1) est apte à distribuer de la lumière dans la première nappe et un deuxième élément d’injection de lumière (320.2) est apte à distribuer la lumière dans la deuxième nappe. La première nappe et la deuxième nappe sont agencées l’une à côté de l’autre de manière à ce qu’un deuxième bord (350.1) de la première nappe de guidage flexible soit en regard d’un deuxième bord (350.2) de la deuxième nappe de guidage flexible. Une partie de la première nappe le long du deuxième bord et une partie de la deuxième nappe le long du deuxième bord sont pliées vers l’intérieur du module lumineux ou sont recouvertes d’un matériau réfléchissant.
