Headlight i.e. adaptive front lighting system headlight, for motor vehicle, has screen for profiling part of light dispersion in upper position of borderline, from traffic in opposite direction, above borderline in dipped beam position

摘要

The headlight has a screen (3) placed in a beam path of light regrouped or emitted by an optical action unit i.e. reflector, and a light source e.g. tungsten halogen lamp. The screen has an upper optical effect edge (7) forming a clarity/darkness borderline in distribution of light. A cylindrical shaped auxiliary screen (11) is placed in beam path. The screen (11) profiles a part of light dispersion in an upper position of the borderline, from the traffic in opposite direction, above the borderline in a dipped beam position, where the upper position is different from the dipped beam position. The cylindrical shaped auxiliary screen acts as a three dimensional object.
