Abstract
The lamellar or strip-shaped floor marking, in particular for means of transportation, in particular airplanes, having a photoluminescent layer on which covering elements which appear dark in comparison with the luminous layer and which serve as a directional indication are arranged in such a way that acute-angled markings pointing in a direction are formed. The covering elements extend over the entire width of the floor marking and taper on both sides at one of their ends so that a recess bounded by an acute-angled isosceles triangle is formed there. The covering elements are substantially adjacent to one another, at least in groups, in such a way that the distance between them is smaller than approximately three times their longitudinal extent.
