Abstract:
1. A motor vehicle headlamp, comprising a light source for generating light, a mirror possessing first and second focal regions, and a converging lens, the source being placed in the first focal region and the lens having a focus located in the second focal region, the mirror and the lens having axes which are essentially coincident defining an optical axis of headlamp, and the headlamp further including a mask located in the region of the focus of the lens, in order thus to project a beam having an upper cut-off defined by said mask, and the mirror having at least a first area for concentrating the light in the vertical direction, towards a vertical focusing baseline extending substantially horizontally and transversely to the optical axis and passing close to the focus of the lens, wherein the mirror further comprises at least one corrected vertical focusing area for concentrating the light, in the vertical direction, towards a second vertical focusing baseline separate from said vertical focusing baseline in the axial direction, in order thus to increase a width of the light reflected by said first area along said optical axis.
