Abstract
The invention concerns a light module with a light source, a primary optical system and a reflector. The primary optical system contains a lens element that is embodied as a sector of an imaginary rotation body formed by the rotation of an imaginary rotation base surface around a rotation axis, wherein the rotation base surface is designed such that the lens element contains a light entry surface that faces the rotation axis and that surrounds the rotation axis and a light emitting surface that is located radially exterior to the rotation axis, wherein the reflector has at least one reflector zone that is embodied as a segment of the surface of a rotation symmetric imaginary associated circular cone, and wherein the axis of symmetry of the circular cone extends parallel to the rotation axis of the lens element.
