The module has a reflector (5) situated below a horizontal plane passing through an optical axis. The reflector passes a meridian curve (6) composed of an arc of ellipse (7), and a curve situated in front of an end of the arc of ellipse. An annular lens (10) surrounds a zone of a lower part of a convex lens (4). The lens (10) presents a plane (11) passing through the optical axis and providing two curves corresponding to input and output sides of the lens (10) and to a cut of the convex lens. |
