  • Patent number: 4608623
    Abstract: A headlamp for an automobile comprising a light source (F.sub.C) a reflector (F) co-operating with this light source in order to reflect in a direction of emission a beam of substantially parallel rays, and a front glass (G) for dispersion and diffusion interposed in the path of the light rays, this glass being inclined with respect to the direction of emission. The glass has on its internal face, correcting optical elements (10) the active surface (11) of each of which is defined by the intersection of a prism inclined by an angle .alpha. with respect to the vertical plane passing through the direction of emission and having an angle .beta. at the apex, and a cylindrical rib having an axis parallel to the prism and a radius r, in such a way that the inclination .alpha. of the prism compensates for the effect of vertical deflection caused by the inclination of the glass.

  • Patent number: 4567550
    Abstract: The invention relates to an automobile headlamp having a light source co-operating with a principal reflector of generally parabolic form, and a glass which is greatly inclined with respect to the vertical. Selected critical zones of the reflector have an elliptical form with one focus in the proximity of the light source and the other focus in the proximity of the center of the glass, and the central zone of the glass is substantially smooth, in such a way that the light rays reflected by the critical zones of the reflector pass through the glass without significant deflection in spite of its inclination.
