Lighting Unit for a Motor Vehicle Headlight for Generating a Light Distribution Having a Light-Dark Boundary

A lighting unit for a motor vehicle headlight for generating a light distribution with a light-dark boundary, the lighting unit (1) comprising:

• at least one light source (2);
• at least one first reflector (R1) having at least one focal point (F1R1), wherein the at least one light source (2) is arranged in the at least one focal point (F1R1);
• at least one second reflector (R2) having at least one focal point (F1R2), wherein the at least one first reflector (R1) is configured to emit and forward light to the at least one second reflector (R2) and wherein the at least one second reflector (R2) is arranged downstream of the at least one first reflector (R1) in a beam path (S) and is configured to display an intermediate light image generated by the first reflector (R1);
• and
• at least one aperture (B) which is arranged in the beam path (S) between the at least one first reflector (R1) and the at least second reflector (R2),
• wherein:
• the first reflector (R1) is constructed in at least two parts (R11, R12) and has a first reflector portion (R11) and at least one separate second reflector portion (R12), each reflector portion (R11, R12) having at least one focal point (F1R11, F1R12) in each case, and
• at least one focal point (F1R11, F1R12) of the first and the at least second reflector portion (R11, R12) is arranged in each case congruently at the location of the at least one light source (2),
• the at least two part first reflector (R11, R12) splitting is configured to split the beam (S1) exiting from the at least one light source (2) into at least two separate beams (S11, S12),
• the at least one aperture (B) is arranged in such a way that it is associated with the first reflector portion (R11) of the first reflector (R1) and is arranged at a small distance (D1) near the beam (S11) emitted from the first reflector portion (R11), and clips the intermediate light image generated in the first reflector portion (R11) to form a light-dark boundary, and
• the at least one aperture (B) is arranged at a greater distance (D2) away from the beam (S12) emitted from the at least second reflector portion (R12) and the intermediate light image generated in the second reflector portion (R12) is substantially free of influence of shadowing of the aperture arrangement.
