Abstract

L'invention concerne une lentille optique avec une surface d'entrée de lumière et une surface de sortie de lumière, la surface de sortie de lumière (11) ou la surface d'entrée de lumière (10) étant fractionnée en segments de surface (110) gradués, réalisés en surfaces de forme libre. L'invention concerne en outre un dispositif d'éclairage avec au moins une source de lumière (20) et au moins une telle lentille optique (1). Le dispositif d'éclairage sert de préférence de phare de véhicule et les sources de lumière sont de préférence des modules de diodes électroluminescentes (20).
