Abstract

L'invention porte sur un élément guide de lumière comportant une feuille transmettant la lumière (2), présentant une première surface (21) et une seconde surface (22) d'une épaisseur comprise entre 200 et 800 µm, une couche en résine photodurcissable transmettant la lumière (4) fixée à la première surface (21), et une couche en résine photodurcissable transmettant la lumière (6) fixée à la seconde surface (22). La surface de la couche en résine photodurcissable (4) présente une structure mate, alors que la surface de la couche en résine photodurcissable (6) présente une structure en réseau de prismes. La somme de l'épaisseur moyenne dela couche en résine photodurcissable (4) et de l'épaisseur moyenne de la couche en résine photodurcissable (6) n'excède pas 30 µm.
