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 .alpha. and a second side at an angle .beta. from the base which is length 1. The rib structure runs in a rolling direction, .alpha. is an angle of 5 to 60.degree., .beta. at an angle of 10 to 90.degree., 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.sub.1 that is less than l/10.
