The lighting module comprises at least one lighting engine configured for forming a light beam with a cut-off line running along one or more axes, and at least one lens designed to project the light beam with a cut-off line. The lens comprises diffractive elements which correct all or part of the chromatism of the lens, and it comprises a central region which is lacking any diffractive elements.
