1. A lighting device for a motor vehicle, the lighting device comprising:
a printed circuit board populated with numerous light-emitting diodes;
an optical panel; and
a reflector element between the printed circuit board and the optical panel;
wherein the reflector element is subdivided into numerous segments;
wherein each light-emitting diode is dedicated to a said segment, such that the light from the light-emitting diodes is reflected by the segments of the reflector element and passes through the optical panel; and
wherein each segment of the reflector element has a reflector foot that surrounds the respective light-emitting diode and contacts the printed circuit board at a contact surface, wherein a ratio of a height of the light-emitting diode to a height of the reflector foot is 1:1 to 1:3, the reflector foot including:
a plateau opposite the contact surface; and
an optical surface positioned between the plateau and the contact surface, the entire optical surface being configured to reflect the light from the light-emitting diode.
