Claim:
1. A light module for a lighting system of a motor vehicle, comprising: a plurality of semiconductor light sources for emitting light; a primary lens element for concentrating the light emitted from the semiconductor light sources in sections perpendicular to a sagittal plane of the light module, wherein the primary lens element includes a plurality of disk-like light conducting sections extending in a plane perpendicular to the sagittal plane, wherein each light conducting section includes a light coupling surface and a light decoupling surface, and is designed to conduct light, with total internal reflection, from the light coupling surface to the light decoupling surface, wherein each light conducting section is allocated to a semiconductor light source such that light from the semiconductor light source can be coupled with the respective light coupling surface in the light conducting section, wherein each light conducting section includes a main reflection surface, which is convex curved with a parabolic shape such that a primary focal line allocated in each case to the light conducting section is defined, wherein the primary focal line extends in, or parallel to, the sagittal plane; and a secondary lens element provided downstream of the primary lens element in the beam path, wherein the secondary lens element is a cylindrical lens that defines a secondary focal line that runs perpendicular to the primary focal line such that the light passing through the plurality of light decoupling surfaces of the plurality of light conduction sections can be concentrated in sections parallel to the sagittal plane by the secondary lens element and wherein the light decoupling surfaces of the light conducting sections lie between the secondary focal line and the secondary lens element.
