A process for manufacturing a panel light-guiding element, including the step of rolling a metal body of one of aluminum and an aluminum alloy in at least one pass between at least two rolls to form a rolled product having at least one structured surface as a light guiding structure having a rib pattern of height h and a tooth-like cross-section. The tooth-like cross-section have a periodic structure of rows of triangles. The triangles have bases which follow each other, a first side of each of the triangles running at an angle &agr;, and a second side at an angle &bgr; from the base which has a length l. At least one of the rolls exhibits an embossed pattern that is structured to form the rib pattern in a rolling direction over a full length of the rolled product and is tooth-like in cross-section so that the angle &agr; is in a range of 5 to 60&deg;, the angle &bgr; in a range of 10 to 90&deg;, the length l in a range of 0.01 to 10 mm and the height h is 0.1 to 2 mm.

Rolled metal product used as a light-guiding structure

A light-guiding panel element arrangeable on a wall or a ceiling for lighting purposes. The light-guiding panel element including a walled metal body having at least one structured surface as a light deflecting structure with a ray of the pattern height h and a toothed-like cross-section. The tooth-like cross-section represents a period structure of rows of triangles. The triangles have bases that follow each other. A first side of each triangle runs at an angle &agr; and a second side at an angle &bgr; from the base which is length 1. The rib structure runs in a rolling direction, &agr; is an angle of 5 to 60&deg;, &bgr; at an angle of 10 to 90&deg;, a length l is 0.01 to 10 mm and the height h of the rib pattern is 0.1 to 2 mm. A line of contact of both sides of each triangle forms an edge with a radius r that is less than l/10.
