Abstract (en)
A reflector (1) having a complex surface for an illumination device of a vehicle, mountable on the illumination device with its optical axis (3) substantially parallel to a motion plane (4) on which the vehicle moves: the complex reflecting surface (2) of the reflector (1) is constituted by a plurality of elementary sectors (5) having respective elementary reflecting surfaces (6) adjacent one another and joined together along respective adjacent sides (10) to constitute the said complex reflecting surface (2): in the preferred embodiment the elementary sectors (5) are of polygonal shape with four sides (10) and are orientated in such a way that the sides (10) are not parallel to the motion plane (4) but have a predetermined inclination with respect thereto: in comparison with known configurations of comparable dimensions improved photometric performance is obtained. <IMAGE> <IMAGE>
