Motor-vehicle lighting module that produces a cutoff with a reflector the surface of which is partially grained

A luminous device for an automotive vehicle, comprising:

• a main lighting module configured to project a main light beam, extended horizontally and with a horizontal upper cutoff, when the luminous device is in a mounting position on the automotive vehicle;
• and
• at least one additional lighting module configured to project an additional light beam, restricted and central horizontally and with a horizontal upper cutoff, when the luminous device is in the mounting position on the automotive vehicle;
• the at least one additional lighting module including a light source adapted to emit light rays,
• a collector with a reflective surface configured to reflect the light rays in a reflected beam,
• an optical device configured to project the reflected beam in a projected beam along an optical axis of the lighting module by imaging a portion of the reflective surface, wherein the reflective surface includes a front edge and a grained front area including the front edge;
• wherein at 25 m, the projected beam is restricted horizontally and vertically within an area bounded horizontally between −15° and +15° and vertically between −4.5° and +1.5° relative to the optical axis,
• wherein the projected beam produces an overall illumination of less than 1 lux outside the area bounded by −15° and +15° horizontally and bounded by −4.5° and +1.5° vertically relative to the optical axis when the lighting module is mounted on the automotive vehicle.
