<p>The module (M1) has a concave collecting reflector (R1) receiving a beam issued from an LED (1) and sending the beam towards an output reflector (R2), where an average emission direction (D) of the LED is parallel to an optic axis (X-X). The reflector (R2) is determined for transforming a semblance wave from a rectilinear edge (4) of a virtual light spot (3) into a cylindrical wave of a vertical axis (Z1) orthogonal to direction of the axis (X-X) and to the edge, so that an outputting beam is top or below side of a plane orthogonal to the axis of the cylindrical wave.</p> |
