1. A lighting device for a motor vehicle, the lighting device comprising:
a printed circuit board populated with numerous light-emitting diodes;
a reflector element positioned on a side of the printed circuit board, wherein the light-emitting diodes are also positioned on said side of the printed circuit board, wherein the reflector element is subdivided into numerous polygonal segments that can be combined to form light patterns having the shape of a polygon, and wherein each light-emitting diode is dedicated to a segment that reflects light from each of the light-emitting diodes away from the printed circuit board in a beam direction(S);
an optical element positioned downstream of the reflector element in the beam direction (S), wherein the optical element extends over at least part of a reflective surface of the reflector element, and the optical element has a variety of optical properties over this reflective surface, and
a diffusing optical layer positioned between the reflector element and the optical element.
