<p>A headlamp for motor vehicles has a refractor (2) provided with a zone (21) of spread elements (22) below the upper edge (11) of the reflector (1). Their distance (W), height (H), width (S) are function of the parameter (p), polar vector of the profile of the reflecting surface of reflector (1), whereby the zone (21) of the spread elements (22) is vertically of wedge form with the basis of the refracting angle ( THETA 2V) at the upper side. The spread elements (22) are vertical strip flutes of radius (R) and width (T) that can be horizontally of wedge form with the basis of the refracting angle ( THETA 2H) at the side of the central road surface line. <IMAGE></p> |
