Abstract: A motor vehicle component consisting of a metal profile element and a lighting element. The profile element has a channel extending in the longitudinal direction of the profile with an externally accessible opening extending in the longitudinal direction of the profile. The lighting element serves to produce a strip of light radiating in the longitudinal direction of the profile, and is arranged in the channel of the profile element so as to be concealed behind an outer surface of the profile element so that the radiated light does not arrive directly at the outside, but instead is reflected outward by a reflecting surface of the profile element.

Abstract: The invention relates to a simple Fresnel structure that can be produced automatically and easily, and can be used for broad application in the use of solar energy or as a reflector in the lighting industry. A Fresnel mirror according to the invention for the directed reflection of light is made of a flat carrier part (10) having a Fresnel structure (20) on the upper side thereof, wherein the individual steps (21, 22, 23) of the Fresnel structure (20) have a reflective surface as an active surface (30).
