发明名称 Headlamp system for motor vehicles
摘要 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.

主权项 1. A projector headlamp, comprising: a system of light sources; a cooling system; a reflector comprising: an upper part with a first focal point and with a second focal point, anda lower part with a first focal point and with a second focal point; an aperture arranged with its cutoff edge in proximity to an optical axis of the headlamp; and a convergent lens comprising at least two segments with their own first focal points, wherein a first segment situated in a lower part of the convergent lens has a greater optical power than a second segment situated in an upper part of the convergent lens, and the first focal points of the individual segments of the convergent lens are located near the optical axis of the headlamp between the light sources and the convergent lens, wherein the system of light sources comprises at least two light sources, where a first light source adjoins the first focal point of the upper part of the reflector and a second light source adjoins the first focal point of the bottom part of the reflector, and also the first focal point of the first segment of the convergent lens is adjacent to a cutoff edge of the aperture or aperture in a first position and the first focal point or points of the second or other segments of the convergent lens lie outside a region of the first focal point of the first segment behind and beneath the first focal point of the first segment of the convergent lens in the direction of the path of light rays from the reflector to the lens, and the second focal point of the upper part of the reflector is adjacent to the first focal point of the first segment of the convergent lens and the second focal point of the bottom part of the reflector is adjacent to the first focal point of the first segment or the first focal point of the second segment of the converging lens.
