The module has reflectors (3, 4) each comprising an optical axis passing through a focus (F2) of a reflector (2) and perpendicular to an optical axis of the reflector (2). A folder (5) arranged between the reflectors (3, 4) has an upper reflecting surface (10) carrying the optical axis of the reflectors (3, 4). The surface permits to fold images of light source (6) reflected by elliptical surface (7) of the reflector (2) to the focus. |
