Abstract:
1. An illumination system for forming a low beam in traffic applications comprising a light source and a reflecting surface formed by a multiplicity of reflector segments arranged around a central optical axis, wherein the light source is positioned in a focal point of the reflecting surface, the light source having a major axis parallel to the central optical axis, the light source in operation emitting light over an angle of at most 180° in a direction facing away from the intersection of the central optical axis and the reflecting surface and toward the emission window, and in that each of the reflector segments is parabolically-shaped and has a segment optical axis parallel to the central optical axis, wherein each reflector segment is positioned such that the segment optical axis substantially intersects with an edge of the light source, such that the reflector segment optical axis aligns with the central optical axis of the reflecting surface forming a sharp cutoff between an illuminated area and a glare area of the light beam without the aid of occulting elements.
