Abstract
The invention concerns a lighting module for motor vehicles, including at least one first row of first illumination units configured to produce a first exit beam, each first illumination unit including a first light source and a first optical element configured to produce a first unitary beam from light rays coming from the first light source, characterized in that the first optical element of each of the first illumination units is configured to produce: a first total internal reflection of the rays coming from the first light source so as to form a reflected beam of collimated rays; a second total internal reflection of the collimated rays so as to generate the first unitary beam.

Lighting module for motor vehicles, comprising at least one first row of first illumination units configured to produce a first exit beam, each first illumination unit comprising a first light source and a first optical element configured to produce a first unitary beam from light rays coming from the first light source, wherein the first optical element of each of the first illumination units is configured to produce:
- a first total internal reflection of the rays coming from the first light source so as to reflect and collimate the rays from the first light source to form a reflected beam;
- and
- a second total internal reflection of the reflected beam so as to generate the first unitary beam.
