Dipped headlamp for motor vehicles

A dipped headlamp for motor vehicles comprising a bulb and a reflector having a reference axis and a closure glass placed in front of the bulb ad the eflector, and adapted to create a light beam under a cut-off defined in a standardized vertical transverse screen by two horizontal half-lines at different heights, and on the opposite sides of a vertical center line, the left-hand half-line being at the lower level;

• said bulb being an axial filament bulb with its light-emitting surface completely exposed,
• said reflector comprising a reflecting surface without any discontinuity and forming on said screen images of the filament such that substantially all points of said images are below a horizontal line contained in said screen and intersecting the reflector axis, and the side portions of the reflector forming images of the filament smaller than the center portion thereof,
• the axis of the filament and the axis of the reflector being both inclined downwardly with respect to the horizontal in such manner that said horizontal line is at the same level as the lower half-line of the cut-off,
• the axis of the filament and the axis of the reflector being further inclined to the right at an angle corresponding to about one half of the horizontal extent of said concentration images, and
• the headlamp further comprising correction means associated with said side portions of said reflector for angularly displacing said concentration images upwardly to the level of the right-hand upper half-line.
