Lighting Unit for a Motor Vehicle Headlight for Generating a Light Distribution Having a Light-Dark Boundary
The invention relates to a lighting unit for a motor vehicle headlight for generating a light distribution having a light-dark boundary, wherein the lighting unit (1) comprises a light source (2), a first reflector (R.sub.1) having at least one focal point (F.sub.1R1) in which the light source (2) is arranged, a second reflector (R.sub.2) having at least one focal point (F.sub.1R2), wherein the second reflector (R.sub.2) is arranged downstream of the first reflector (R.sub.1) in the beam path (S), and an aperture (B) arranged between the first reflector (R.sub.1) and the second reflector (R.sub.2). The first reflector (R.sub.1) has a first reflector portion (R.sub.11) and at least one second reflector portion (R.sub.12), the aperture (B) being arranged in such a way that it is associated with the first reflector portion (R.sub.11) of the first reflector (R.sub.1) and is arranged at a small distance (D.sub.1) near the beam (S.sub.11) emitted from the first reflector portion (R.sub.11), and clips the intermediate light image generated in the first reflector portion (R.sub.11) to form a light-dark boundary, and the intermediate light image generated in the second reflector portion (R.sub.12) is substantially free of influence of shadowing of the aperture arrangement.
Thin aspect lighting system with cutoff
A thin aspect lighting system and method are shown. The system and method include at least one module having a reflector that is generally elliptical in one cross-section and generally parabolic in another cross-section. Each module is adapted to generate at least one of a flat beam pattern, a high beam pattern or a low beam pattern, such as a low beam pattern with a kink or elbow. Also shown is a headlamp assembly having a plurality of modules that generate the same or a different light beam pattern. Manipulation and variation of facets and/or positions of various components, such as at least one light source, have been found to provide improved characteristics in one or more of the light beam patterns.
