Abstract

L'invention concerne un ensemble de projecteurs qui comprend au moins un groupe projecteur (10) qui comprend lui-même plusieurs sous-groupes projecteurs (20, 30, 40), émettant des faisceaux lumineux présentant des caractéristiques différentes. Un faisceau lumineux de croisement de base est émis par au moins un sous-groupe projecteur (20). Au moins un autre sous-groupe projecteur (30), disposé à proximité du bord extérieur (14) du véhicule, émet un faisceau lumineux dispersé sur un côté, en direction du bord extérieur (14) du véhicule, faisceau par lequel le tracé de la trajectoire de roulement, dans une courbe, est mieux éclairé dans le sens du bord de véhicule que par le faisceau lumineux de croisement de base. Un sous-groupe projecteur (40) complémentaire, disposé plus haut que le sous-groupe projecteur (20) émettant le faisceau lumineux de croisement de base, émet un faisceau lumineux concentré par lequel est éclairée, de façon complémentaire, la zone éloignée se trouvant au-dessous de la limite de clair-obscur du faisceau lumineux de croisement de base, ce qui constitue un avantage, en particulier lorsque le véhicule roule à grande vitesse.
