Abstract

In a headlight for antidazzle lamps for motor vehicles, a reflector and a shield or screen, and an objective form a light beam illuminating a roadway in accordance with law requirements. The lower portion of the reflector forms a paraboloid-ellipsoid-shaped section which generates an additional light beam below the screen and the objective. The additional light beam is received by horizontal scattering prisms on a transparent pane.
