Abstract

Lentille de projection (4) comprenant une première partie (7) configurée pour générer un premier faisceau lumineux dit « feu de croisement » et une deuxième partie (8) configurée pour générer un faisceau lumineux complémentaire se superposant au moins en partie au premier faisceau lumineux, ce premier faisceau lumineux et ce faisceau lumineux complémentaire formant collectivement un deuxième faisceau lumineux de type « feu de route », caractérisé en ce que la deuxième partie (8) comprend au moins un collimateur (13) issu de matière avec cette deuxième partie (8) et formant une face d'entrée (14) de cette deuxième partie (8) de la lentille de projection (4).Projection lens (4) comprising a first part (7) configured to generate a first light beam called "dipped beam" and a second part (8) configured to generate a complementary light beam superimposed at least in part on the first light beam , this first light beam and this complementary light beam collectively forming a second light beam of the "high beam" type, characterized in that the second part (8) comprises at least one collimator (13) made of material with this second part ( 8) and forming an inlet face (14) of this second part (8) of the projection lens (4).
