Abstract

Un dispositif émetteur de lumière comporte un corps émetteur de lumière plan (22) configuré pour émettre de la lumière sous forme plane, et un élément transparent (24) configuré pour commander la lumière provenant du corps émetteur de lumière plan (22). L'élément transparent (24) comporte une surface d'incidence de lumière (25) agencée de manière à être tournée vers la surface émettrice de lumière (22a) du corps émetteur de lumière plan (22) et configurée pour que la lumière provenant du corps émetteur de lumière plan (22) soit incidente sur l'élément transparent (24) et une surface d'émission de lumière (26) configurée pour émettre vers l'extérieur la lumière qui se propage dans l'élément transparent (24). L'élément transparent (24) est formé de façon à s'étendre dans une direction prédéterminée et formé de sorte que la distance entre la surface d'incidence de lumière (25) et la surface d'émission de lumière (26) varie en fonction de la position dans la direction prédéterminée.
