Abstract (en)
A motor-vehicle adaptive head-lamp has a diaphragm (6) located at the front of a central area of a reflector (2) with which a light source (3) is associated constituted by a discharge lamp. The annular area of the reflector (2) surrounding the central area is adapted to generate a light beam having a predetermined basic pattern. The opening of the diaphragm (6) uncovers an optical element (10) constituted by lens sectors adapted to generate additional patterns so as to give rise to a plurality of different beams, adapted to the different travel and environment conditions, which can be selected by varying the opening degree of the diaphragm (6). <IMAGE>
