Abstract

A lighting device having a light source, an optical element associated with the light source and designed as a reflection lens which, in a central region accommodating an optical axis of the optical element, has a lens section which has a first coupling-in surface on a coupling-in side and a first coupling-out surface on a coupling-out side. The light source is tilted and/or is arranged rotated about the optical axis in the plane running perpendicular to the optical axis, with the formation of an obliquely running edge of the light source, and the first coupling-in surface, the second coupling-in surface, the reflection surface, the first coupling-out surface, and/or the second coupling-out surface of the optical element are shaped in such a way that the predetermined light distribution is produced with imaging of the edge of the light source as a cut-off line.
