Abstract

La présente invention permet à une zone d'émission de lumière disposée à l'intérieur d'un véhicule d'être coordonnée avec des éléments environnants en l'absence d'émission de lumière et d'avoir des variations accrues de motifs d'émission de lumière. Une unité d'éclairage de véhicule qui amène une zone d'émission de lumière (100) disposée à l'intérieur d'un véhicule à émettre de la lumière comprend : un corps rayonnant qui rayonne de la lumière ; un substrat disposé au niveau d'une position à l'avant du corps rayonnant ; un film décoratif disposé au niveau d'une position à l'avant d'un corps transparent ; et un dispositif de commande qui commande le corps rayonnant. Pendant l'absence d'émission de lumière depuis la zone d'émission de lumière, la manière de décorer une face exposée de la zone d'émission de lumière (100), constituée du film décoratif, correspond à la manière de décorer des faces exposées de zones non émettrices de lumière (20, 21) voisines de la zone d'émission de lumière (100). Pendant l'émission de lumière depuis la zone d'émission de lumière (100), le dispositif de commande commande le corps de rayonnement de telle sorte qu'un point d'émission de lumière (11a) se déplacera régulièrement sur la face exposée d'une deuxième section d'émission de lumière (11) constituant la zone d'émission de lumière (100).
