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.

Lighting unit for a motor vehicle headlight for generating a light distribution having a light-dark boundary

The invention relates to a motor vehicle headlamp () containing an ellipsoid reflector (), which allows light coupled in from a light source () to exit through a reflector light exit opening (), a collimator () and a projection optical unit (). The collimator () is designed to collimate the incident light beam coming from the ellipsoid reflector () and to direct the same toward a first image plane (). The projection optical unit () projects a light image produced by the light beam in the emission direction of the motor vehicle headlamp () in accordance with a second image plane () of the projection optical unit (). The first image plane () and the second image plane () intersect or overlap with one another. In the beam path of the light beam, an optical element () having at least one optically active edge () is arranged between the collimator () and the projection optical unit () in such a way that the first and/or second image plane () runs through the optical element (), in Order to mask a part of the light beam and to guide another part to the projection optical unit ().
