Abstract
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.
