    Patent number: 5014166
    Abstract: A motor vehicle headlamp comprising a dished body having an ellipsoidal inner reflective surface. A lamp filament is disposed at an inner focal point of the surface. A diverging meniscus lens element having a smooth convex rear surface is disposed between the reflective surface and a front cover. The lens element has a smooth concave outer surface, although the latter may be a concave fresnel lens. The convex rear surface of the lens element reduces the risk of unwanted light scatter compared with the use of a concave rear surface.
