1. A headlamp for a vehicle, configured to generate a lighting region in front of the vehicle and comprising:
a fixed matrix-array first light source configured to emit a high beam,
a movable second light source configured to emit a low beam,
a correcting mechanism configured to keep a vertical inclination of the low beam constant with respect to a reference horizontal line, when the vehicle is in motion, and
a dioptric prism configured to remove at least one shadow region that may occur in said lighting region, between the high beam and the low beam,
wherein the dioptric prism is movably mounted, in front of the first light source, to be movable between:
a working position, allowing refraction of the incident rays of the high beam, and
a rest position, with no effect on said incident rays;
and in that said dioptric prism comprises:
a flat incident face, and
a flat diopter from which the incident rays emerge from the dioptric prism in a refracted beam intended to project the high beam in the lighting region in a manner adjacent to or partially superimposed on the low beam.
