A reflector for a dimmed or dimmable motor vehicle headlight is divided into an asymmetrical wedge-shaped sector, an upper sector, and a lower sector which are stepped axially from on another. The reflection surface is thereby formed such that a desirable light distribution is achieved without a correcting lens in horizontal and vertical areas perpendicular to a middle axis of the headlight. The desired light distribution of the asymmetrical wedge-shape sector is such that a corresponding point of every reflected light-filament image of each arbitrary point of the asymmetrical wedge-shaped reflection surface is positioned immediately near a prescribed borderline, such as a legislatively mandated borderline.

Reflector for dimmed or dimmable motor vehicle headlights

The opening in the bowl-shaped plastic reflector is surrounded by a collar. Inserted into the collar is an incandescent lamp with a flange that surrounds its base and rests against the face of the collar. The lamp is secured to the reflector with a wire spring that is bent along the optical axis into the shape of a U at the rear of the reflector. The two legs of the spring are tensioned against opposite sides of the collar. The free ends of the legs rotate in a mount. Another mount is positioned on the other side of the collar and has a projection that extends out more or less radially in relation to the optical axis of the reflector and creates an undercut. The web that connects the legs automatically snaps into the undercut. The web has a lever in the form of a bent-in eye that rotates when forced down along the optical axis around a section of the second mount that parallels the web of the spring.

Headlight for vehicles

The invention concerns a headlight for motor vehicles, with a cover plate that covers up the reflector. An essentially U-shaped enclosure made out of sheet metal is positioned in the vicinity of the lamp, which fits into an opening in the vertex of the reflector. The flanks of the enclosure extend above and below but not in contact with the lamp, at least to some extent constituting a screen that screens off sections of the reflector that generate diffused light. The flank below the lamp also functions essentially as a supporting arm for the enclosure. The free terminal section of the supporting arm above the lamp has a third screen. A tongue is punched and bent out of the area of the U-shaped enclosure between the lamp and the cover plate and constitutes the upper supporting arm.

Headlight for motor vehicles

A vehicle headlight for providing a shaped beam spreading as a flat bundle. A dish-shaped reflector is employed where the inner reflection surface in the axial longitudinal sections in each case forms an ellipse segment, where the ellipse eccentricity increases from the longitudinal section spanned by the vertical and the reflector axis to the longitudinal section spanned by the horizontal and the reflector axis, where the focal points of the ellipse segments of all sections disposed in planes containing the reflector axis coincide, and where the vertices of the ellipse segments of all sections disposed in planes containing the reflector axis coincide. The depth of the reflector within the longitudinal sections of the reflector containing the reflector axis corresponds to the longer half-axis of the respective ellipse.
