Abstract

PHARE POUR UN VEHICULE Un phare (1) pour un véhicule comprend une source de lumière (41). La source de lumière (41) comprend : un substrat (42) ; une plaquette de diode électroluminescente (43) ; et un phosphore (44). De la lumière qui sort d’une surface d’émission de lumière pénètre à travers le phosphore (44). Le phosphore (44) comprend une surface de sortie (41L) à travers laquelle la lumière de la surface d’émission de lumière (43L) pénètre et sort. Une première direction de la surface de sortie (41L) correspond à une direction de hauteur d’une configuration de distribution de lumière par la lumière qui sort de la surface de sortie (41L), et une deuxième direction de la surface de sortie (41L) correspond à un étalement dans une direction transversale de la configuration de distribution de lumière. Une dimension dans la première direction de la surface de sortie (41L) est plus petite qu’une dimension dans la deuxième direction de la surface de sortie (41L). Figure pour l’abrégé : Fig. 4.
