Rolled metal product as light deflecting structure

摘要

The invention concerns a light-guiding metal structure in the form of a rolled product which is provided with at least one structured surface by means of a rolling process. The structured surface is a rib pattern which extends in the direction of rolling and has a tooth-shaped cross section. The tooth-shaped cross section forms a periodic structure in the form of a row of adjacent triangles, the bases of these triangles following one another. The one lateral side of any triangle projects at an angle alpha from the base ab and the other lateral side projects at an angle beta , and the base of each triangle has a length l, alpha being an angle of between 5 and 60 DEG , beta being an angle of between 10 and 90 DEG , and the length l being between 0.01 mm and 10 mm.
