Title
(EN) VEHICLE LAMP
(FR) LAMPE DE VÉHICULE
(JA) 車両用灯具
Abstract
(EN)
The vehicle lamp is provided with: a mirror (10) capable of rotating a mirror surface, which is aligned with a vertical rotational axis, about the rotational axis; multiple light-emitting elements (31) disposed lateral to the mirror in a vehicle width direction; and a lens (50) for directing light beams from the light-emitting elements over a wider area than the mirror. The light-emitting elements are disposed apart from each other such that light-distribution images of light beams reflected off the mirror surface are arranged side-by-side in the vehicle width direction, and the mirror rotates so as to combine adjoining light-distribution images to form a main light-distribution pattern.
(FR)
L'invention concerne une lampe de véhicule pourvue : d'un miroir (10) apte à tourner une surface de miroir, qui est alignée avec un axe de rotation vertical, autour de l'axe de rotation ; de multiples éléments électroluminescents (31) disposés latéralement par rapport au miroir dans une direction de largeur de véhicule ; et une lentille (50) servant à diriger des faisceaux lumineux provenant des éléments électroluminescents sur une zone plus large que le miroir. Les éléments électroluminescents sont disposés à distance les uns des autres de sorte que des images de distribution de lumière de faisceaux lumineux réfléchis par la surface de miroir soient disposées côte à côte dans la direction de largeur du véhicule, et le miroir tourne de façon à combiner des images de distribution de lumière adjacentes pour former un motif de distribution de lumière principal.
