Abstract

L'invention concerne une plaque de guidage de la lumière (100) comprenant une face d'introduction de la lumière (110) qui introduit de la lumière ; une face d'extraction de la lumière (120) qui extrait la lumière introduite par l'intermédiaire de la face d'introduction de la lumière (110) ; et une face arrière (130) qui est située du côté opposé par rapport à la face d'extraction de la lumière (120). L'épaisseur de la plaque de guidage de la lumière est de 0,020 mm - 0,500 mm, au moins l'une de la face d'introduction de la lumière (120) et/ou de la face arrière (130) comprend en outre un motif constitué d'au moins de creux ou de protubérances ; la proportion occupée par le motif étant comprise entre 0,02 et 0,2 fois l'épaisseur de la plaque de guidage de la lumière (100) inclus.
