Claim:
1. A concentric lighting module with a concentric axis and a conical mirror that tapers inwardly along the concentric axis toward an active surface for creating of a three-dimensional optical effect, especially in the outer brake and tail lights of a motor vehicle, wherein in a peripheral region of the conical mirror, a cylindrical output part of a light guide is provided by at least one offset on its outer side, terminating in the active surface and coupling in the region beyond the conical mirror to the collimator part of the light guide, formed by a parabolic collimator and a lens, applied by its input part against the light source of the module, and at the transition between the collimator part and the output part of the light guide the module is provided with a total internal light reflection surface, whose bottom part forms an optical prism, and wherein light rays from the light source enter the lens and collimator part and strike the total internal reflection surface where they are in turn reflected into the cylindrical output part toward the active surface, and wherein a portion of the light rays in the cylindrical output part strike the at least one offset and are reflected onto the conical mirror and in turn reflected outwardly in a direction along the concentric axis of the lighting module and toward the active surface, and wherein the other portion of the light rays in the cylindrical output part pass through the active surface.
