  • Patent number: 4922386
    Abstract: A projection-type vehicle headlight includes a sheet metal support (11) which provides a light shield (3) between a convex lens (2) and a reflector (1). The support is rigid and has arms (12) which are fastened to the ellipsoid-formed reflector. The arms are appended to a lens frame (13), which receives the lens, of the support. The light shield is in the form of a spherical bulge which extends, or is convex, toward a light source (5), the bulge being produced by "drawing out" areas of the support lying within the lens frame. A light shield edge (6) is formed by "blanking out" an opening in a top half of the spherically shaped bulge.

  • Patent number: 4797790
    Abstract: A dimmed motor vehicle headlight is provided with an ellipsoidally shaped reflector, where a light source is disposed at a first focal point of the reflector. A collector lens is supported by a frame having an annular part which is connected to the reflector and where the lens is disposed behind a second focal point of the reflector. A diaphragm is provided which is in the path of the light beam ahead of the collector lens and disposed at the respective focal point of the collector lens. The diaphragm is provided adjustable and with an upper substantially horizontally running edge that generates a light-dark boundary. The diaphragm and the frame are formed as a single part. The frame is provided by a beaker shaped sheet metal piece, where a cut out floor area serves to support the lens and where arm shaped webs are cut free from a wall forming a jacket face. One of these webs is angled toward the optical axis such that its upper end edge forms the diaphragm edge for the light-dark boundary.
