Abstract

L’invention concerne un module lumineux (1) de véhicule automobile comprenant : une pièce (2) comprenant une pluralité de guides de lumière (3, 31, 32, 36, 37, 38, 4, 41, 42), chacun desdits guides (3, 31, 32, 36, 37, 38, 4, 41, 42) s’étendant entre un dioptre d’entrée (30, 410, 420) de ce guide et une sortie, les guides de lumière (3, 32, 36, 37, 38, 4, 41, 42) adjacents se joignant l’un à l’autre par une jonction (33, 331, 332, 333, 334, 43) de matière ; plusieurs sources lumineuses (9, 91, 92) agencées vis-à-vis des dioptres d'entrée (410, 420) de tout ou partie des guides de lumière  (3, 31, 32, 36, 37, 38, 4, 41, 42) ; et un système de projection (6) en aval des sorties (39, 49) de guide et présentant une surface focale (F) projetant une image de tout rayon lumineux passant par ladite surface focale (F). Selon l’invention, le module lumineux (1) comprend au moins deux guides (4, 41, 42) dont la distance (d1) entre la surface focale (F) et la jonction (43) desdits deux guides (4, 41, 42), est supérieure à la distance (d2) entre la surface focale (F) et la jonction (33, 331, 332, 333, 334) des autres guides (3, 31, 32, 36, 37, 38).
