Abstract

L'invention concerne un module optique (1), comprenant : - un support (2) comprenant une première paroi (20) s'étendant principalement dans un premier plan et une deuxième paroi (21) s'étendant principalement dans un deuxième plan perpendiculaire au premier plan, - au moins une première source lumineuse (3) et au moins une deuxième source lumineuse (4), toutes deux solidarisées à la première paroi (20) du support (2), - un premier élément optique (5) apte à être traversé par des rayons lumineux émis par l'au moins une première source lumineuse (3) afin de former un premier faisceau lumineux dit « feu de croisement », - un deuxième élément optique (6) apte à être traversé par des rayons lumineux émis par l'au moins une deuxième source lumineuse (4) afin de former un deuxième faisceau lumineux complémentaire au premier faisceau lumineux pour former un faisceau lumineux global dit « feu de route », une arête (9) de ce deuxième élément optique (6) étant destinée à former une coupure dans le premier faisceau lumineux, - une lentille de projection (7) solidarisée à la deuxième paroi (21) du support (2) et apte à projeter le premier faisceau lumineux et le deuxième faisceau lumineux, caractérisé en ce que le deuxième élément optique (6) comprend au moins une première partie (60) et une deuxième partie (61), la deuxième partie (61) étant séparée de la première partie (60).The invention relates to an optical module (1), comprising: - a support (2) comprising a first wall (20) extending mainly in a first plane and a second wall (21) extending mainly in a second perpendicular plane in the foreground, - at least a first light source (3) and at least a second light source (4), both secured to the first wall (20) of the support (2), - a first optical element (5) suitable to be crossed by light rays emitted by at least one first light source (3) in order to form a first light beam called a "low beam", - a second optical element (6) able to be crossed by light rays emitted by the at least one second light source (4) in order to form a second light beam complementary to the first light beam to form an overall light beam called a “high beam”, an edge (9) of this second optical element (6 ) being intended to form a cut in the e first light beam, - a projection lens (7) secured to the second wall (21) of the support (2) and able to project the first light beam and the second light beam, characterized in that the second optical element (6 ) comprises at least a first part (60) and a second part (61), the second part (61) being separated from the first part (60).
