Abstract
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 () comprises a light source (), a first reflector (R) having at least one focal point (F) in which the light source () is arranged, a second reflector (R) having at least one focal point (F), wherein the second reflector (R) is arranged downstream of the first reflector (R) in the beam path (S), and an aperture (B) arranged between the first reflector (R) and the second reflector (R). The first reflector (R) has a first reflector portion (R) and at least one second reflector portion (R), the aperture (B) being arranged in such a way that it is associated with the first reflector portion (R) of the first reflector (R) and is arranged at a small distance (D) near the beam (S) emitted from the first reflector portion (R), and clips the intermediate light image generated in the first reflector portion (R) to form a light-dark boundary, and the intermediate light image generated in the second reflector portion (R) is substantially free of influence of shadowing of the aperture arrangement.
