Abstract (en)
[origin: EP2505910A2] The motor vehicle headlight (10) has semiconductor light source (12) and a lens (14) with a projection lens (16) influences a propagation direction of light within the headlight. The projection lens has a main surface (18) and is arranged against an optical axis (28). A point of the main surface of the projection lens has an axial distance (d-32) to the semiconductor light source in the direction of the optical axis. The point is located at a radial distance from the optical axis above the optical axis.
