Abstract
The invention deals with a light module, notably for motor vehicles, comprising a reflector with a reflecting surface , a screen arranged facing the reflector, the screen a semi-reflecting area, and a light guide extending longitudinally along the screen and the reflector. The guide comprises a diffusing output face extending transversally from the semi-reflecting area of the screen to the reflector. A portion of the rays exiting from the output face passes through the semi-transparent area, the other portion being also reflected toward the reflecting surface to form successive images with a depth effect of 3D type, without dark areas between these images.
