Abstract

Une lampe pour véhicule (1) comporte un dispositif d'affichage d'image bidimensionnelle (14) et un groupe de lentilles de projection (20). Le groupe de lentilles de projection (20) projette vers l'avant de la lampe (1) la lumière provenant du dispositif d'affichage d'image bidimensionnelle (14). Le groupe de lentilles de projection (20) comporte une première lentille (21) et une seconde lentille (22). La première lentille (21) est disposée du côté du dispositif d'affichage d'image bidimensionnelle. La seconde lentille (22) est disposée du côté image de la première lentille. Un espace (23) est prévu entre la première lentille (21) et la seconde lentille (22). Le nombre d'Abbe de la première lentille (21) est différent de celui de la seconde lentille (22).A vehicle lamp (1) has a two-dimensional image display device (14) and a group of projection lenses (20). The group of projection lenses (20) projects light from the two-dimensional image display device (14) towards the front of the lamp (1). The projection lens group (20) includes a first lens (21) and a second lens (22). The first lens (21) is disposed on the side of the two-dimensional image display device. The second lens (22) is disposed on the image side of the first lens. A space (23) is provided between the first lens (21) and the second lens (22). The Abbe number of the first lens (21) is different from that of the second lens (22).
