Abstract: The present invention relates to a lighting module for an automobile headlamp that is able to emit a cut-off light beam along a predetermined optical axis. The lighting module includes a light source for generating a beam and an optical element for receiving the beam generated by the light source and configured to form from this beam the cut-off light beam. The optical element has a collimator configured to receive the beam generated by the light source and to collimate this beam into a collimated beam. An optical coupler is configured to couple the collimated beam into a coupled beam in a lightguide. A cut-off means is disposed within the lightguide on the path of the rays of the coupled beam and configured to intercept a portion of the rays in the lightguide and to form a cut-off beam. At least one output face of the lightguide is configured to project the cut-off beam outside of the optical element, and the optical element is formed as a single part.
