Abstract

A projection light module for a motor vehicle headlight with a low-beam diaphragm, which separates a low-beam volume of the projection light module located above this diaphragm from a high-beam volume of the projection light volume located below this diaphragm, and with a high-beam diaphragm arranged in the high-beam volume, which has a vertical diaphragm edge and which divides the high-beam volume into a high-beam volume lying to the right of it and a high-beam volume lying left to it. The low-beam diaphragm and the high-beam diaphragm are components of a composite diaphragm and the high-beam diaphragm is arranged in the high-beam volume obliquely to the optical axis of the projection light module so that its distance from the optical axis of the projection light module increases with increasing distance along the optical axis from the diaphragm edge.
