Abstract

Lampe de véhicule La présente invention concerne une lampe de véhicule comportant une unité de lampe (40) configurée de sorte qu’une lumière émise à partir d’une source de lumière soit émise vers l’avant de la lampe via une lentille de projection (42). L’unité de lampe (40) comporte des première et deuxième sources de lumière comme source de lumière, qui sont allumées dans des modes d’allumage requis respectifs. La première source de lumière comporte au moins un élément électroluminescent (44A) disposé à proximité d’un point focal arrière (F) de la lentille de projection (42). La deuxième source de lumière comporte au moins un élément électroluminescent (44B) disposé à une position obtenue en étant déplacé à partir du point focal arrière (F) dans une direction avant–arrière au–dessus du point focal arrière (F). Des éléments électroluminescents, comportant les première et deuxième sources de lumière, sont montés respectivement sur le même substrat (46) s’étendant obliquement dans la direction avant–arrière de la lampe, par rapport à un plan vertical orthogonal à la direction avant–arrière de la lampe.
