Abstract

The module has a reflector (R) defining an optical axis (X), and a dioptric element i.e. convex lens (L). A light source (S) e.g. LED, is arranged between the reflector and the dioptric element. A folder (P) is placed between the light source and the dioptric element. The folder has a transparent block (B) whose upper edge is partially formed with a reflective coating (Re). The transparent block is disposed perpendicular to the optical axis with lateral walls parallel to each other, where one of the lateral walls is curved.
