Abstract

1,196,109. Vehicle headlamps. SYLVANIA ELECTRIC PRODUCTS Inc. 15 April, 1969, No. 19303/69. Heading F4R. A vehicle headlamp comprises an ellipsoidal reflector 2, a light source 1 at one focus of the reflector, a shield 5 having an aperture 4 at the other focus of the reflector, a lens 7 with its rear focus at the other focus of the reflector, a paraboloidal reflector 3 outside the ellipsoidal reflector with its focus coincident with the one focus of the ellipsoidal reflector, and an annular glass member 9 around the lens, the arrangement being such that at least some of the light reflected by the paraboloidal reflector passes outside the shield 5 and through the member 9. The lens 7 and the member 9 may be made separately, as shown, or in one piece, and the member 9 may consist of plain glass or have refractive properties. The source may consist of a single or multiple filament bulb or a discharge lamp and a mask may be provided to restrict the light to certain areas of the paraboloidal reflector. The headlamp may be circular or rectangular in cross-section.
