1. A method for joining at least two flexible foils, wherein the method comprises the steps of:
providing a first flexible foil having a first row of light emitting diodes and a first set of electrically conductive tracks for supplying current to the first row light emitting diodes;
providing a second flexible foil having a second row of light emitting diodes and a second set of electrically conductive tracks for supplying current to the second row of light emitting diodes; and
joining the first flexible foil and the second flexible foil at an overlap of the first flexible foil and the second flexible foil, wherein a metal strip or wire gets embedded between the first flexible foil and the second flexible foil at the overlap, and wherein the metal strip or wire electrically connects to the first and second sets of electrically conductive tracks.
