摘要： The invention relates to a projection module (1; 10; 20) of an automobile headlight. The module (1; 10; 20) includes several semiconductor light sources (101, 102, 103) to broadcast optical irradiation (104, 105, 106) of a primary optics assembly (110, 111, 112) to bundle the emitted irradiation (104, 105, 106), and a secondary optics assembly (2; 12; 22; 32) that projects the bundled irradiation (113, 114, 115) 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 (2; 12; 22; 32) is formed as a multi-part complex lens that includes several lens segments (3, 4, 5; 13, 14, 15; 23, 24, 25; 33-41). Each of these lens segments (3, 4, 5; 13, 14, 15; 23, 24, 25; 33-41) is assigned to at least one irradiation bundle (113, 114, 115) of irradiation bundled from the primary optics assembly (110, 111, 112), and projects this assembly as partial distribution in front of the vehicle, whereby the overall distribution of the projection module (1; 10; 20) results from overlapping the partial distributions.
