Abstract (en)
[origin: EP2199662A1] The module (1) has a light source (S) i.e. LED, placed in a concave reflector (2). A lens (3) is placed in front of the reflector and the source. The reflector is associated to a beam folder (4). A front edge (5) of the folder is formed by a flat curve with variable curvature, where a curvature in a point (M) is a continuous function of lateral coordinate (x) of the point. The reflector transforms a wave surface of the source into a wave surface restored to the curve. The lens provides an infinity image from the point for all rays contained in a plane perpendicular to the edge at given point.
