Abstract
The invention relates to a projection module of an automobile headlight. The module includes several semiconductor light sources to broadcast optical irradiation of a primary optics assembly to bundle the emitted irradiation, and a secondary optics assembly that projects the bundled irradiation to create the desired light distribution in front of the vehicle. In order to reduce the weight and dimensions of the projection module, it is proposed that the secondary optics assembly is formed as a multi-part complex lens that includes several lens segments. Each of these lens segments is assigned to at least one irradiation bundle of irradiation bundled from the primary optics assembly, and projects this assembly as partial distribution in front of the vehicle, whereby the overall distribution of the projection module results from overlapping the partial distributions.
