Abstract
A projector headlamp includes light sources, a cooling system and reflector comprising an upper part with a first focal point and second focal point and a lower part with a first focal point and second focal point. The headlamp also includes an aperture with a cutoff edge proximate an optical axis of the headlamp and a convergent lens. The convergent lens includes at least two segments with their own first focal points, the first segment in a lower part of the convergent lens has a greater optical power than a second segment in an upper part, the first focal points of the segments located near the optical axis of the headlamp between the light sources and the lens. The light sources comprise at least two light sources, a first adjoins the first focal point of the upper part and a second adjoins the first focal point of the bottom part.
