Abstract

L’invention concerne un dispositif lumineux (100) comprenant des sources lumineuses (110) collaborant avec des guides de lumière (120) et un masque ajouré situé à distance des sources lumineuses (110), le masque ajouré (130) comprenant une grille (131) formant une pluralité de cellules lumineuses (140) en regard des guides de lumière (120) et des sources lumineuses (110) correspondantes. Le masque ajouré (130) permet ainsi de former une surface lumineuse composée d’une pluralité des cellules lumineuses (140), toutes bien délimitées latéralement les unes par rapport aux autres. Afin de mieux homogénéiser une luminance de chaque cellule lumineuse (140), le dispositif lumineux (100) conforme au premier aspect de l’invention comprend aussi un support (150) du type d’un diffuseur (155 collaborant avec le masque ajouré (130) en sortie des guides de lumière (120). Figure pour l’abrégé : Figure 1A
