Abstract

Improvements to the headlights for vehicles, of the type that includes a glass, a parabolic reflector of revolution and a lamp with cylindrical filament centered on the axis of the reflector to one part and another of the focus of the latter, characterized: - that at least one frusto-conical surface centered on the axis of the reflector is associated with one of the faces of the glass so as to deflect in the direction of its greatest length the elementary images given of the filament by the points of the reflector corresponding to said surface frustoconical, - because the angle of said frustoconical surface with respect to said axis is small enough so that the displacement of each deviated elemental image remains less than half the longest of the latter so that the intensity of illumination in the reflector axis direction, and - because said frustoconical surface is limited to a certain sector of the glass so that it confers a non-circular shape to the curves of the same illumination level of the beam emitted by the headlight.
