Abstract: A concentric lighting module with conical mirror for creating of a three-dimensional optical effect, especially in the outer brake and tail lights of a motor vehicle, has in the peripheral region of the conical mirror (3) a cylindrical output part (2c) of a light guide (2) provided by at least one offset (2d) on its outer side, which terminates in an active surface (2e) and which couples in the region beyond the conical mirror (3) to the collimator part (2b) of the light guide (2), formed by a parabolic collimator and a lens and applied by its input part (2a) against the light source (1) of the module, and at the transition between the collimator part (2b) and the output part (2c) of the light guide (2) the module is provided with a total internal light reflection surface (4), whose bottom part also forms an optical prism (4a).

Abstract: Feeding device for a geometrically closed lightguide (1) of the signal lamps of motor vehicles placed on both sides of the vehicle comprising a light feeder (4) and a geometrically closed lightguide (1). The two parts are joined and form a single plastic molding. A prism-shaped cavity (9) with total internal light reflection for a uniform light distribution at both sides of the enclosed lightguide (1) is formed at the site of their joint. A semi-transparent insert (16) is inserted in the prism-shaped cavity (9), made of material with a precise ratio of transparent and cloudy components to control the amount of unwanted light arising on the planar surfaces (10;11) of the prism-shaped cavity (9) with total internal light reflection.
