摘要： A headlamp comprising a reflector of which at least one sector is in the form of a paraboloid of reduction, a bulb with an axial filament offset upwards in the radial direction with respect to the axis of the paraboloid, and a light-distributing glass placed in front of the reflector. The filament is centered in the axial direction on the focus of the paraboloid. The surfaces of the reflector situated outside the sector in the form of a paraboloid are designed so as to produce images of the filament which are all situated below the cut-off. Alternatively, the light-distributing glass participates in the deflection, in combination with the surfaces of the reflector. In an advantageous variant the reflector is completely parabolic and homologous deflecting zones are then provided on the light-distributing glass to lower all the images thus produced below the cut-off.

摘要： The present invention relates to a headlight for automobile, with rectangular front opening, of the type comprising a reflector in the axis of which are disposed a light source for dipped-beam illumination cooperating with cut-off means, and a light source for far-beam illumination, a horizontal upper side and a horizontal lower side intersecting the reflector to delimit the rectangular opening of the headlight, wherein the upper side is substantially closer to the optical axis than the lower side, with the result that, for a total, unchanged height of the headlight, the zone of the mirror furnishing the dipped-beam illumination is reduced, this allowing an optimum compromise for far-beam and dipped-beam illumination.

摘要： A motor vehicle headlight has a single light source and a single reflector which receives the light from the source, and which is tripod mounted on three bearing points defining the three apices of a triangle. The headlight has controlled displacement means for selectively displacing at least one of these bearing points in straight line movement. The controlled displacement means comprise a single beam switching device for displacing one of the three bearing points into one of only two discrete positions, namely a first position corresponding to a dipped beam and a second position, higher than the first position, corresponding to a main beam.

摘要： A motor vehicle headlamp lens has two zones A1 and B containing ribs of different width to produce different amounts of lateral spreading of the headlamp beam. Between these zones a transition zone A2 is provided where a gradual change in the width of the ribs occurs. In the transition zone there are provided novel separating surfaces between the ribs having one surface at an angle to the general plane of the lens which act as a prism to deflect light passing therethrough in a downward direction. In zones A1 and B, and in transition zone A2 the total thickness e of the lens at the crest of any rib is constant.
