Method for joining flexible foils comprising LEDs

Abstract

The present invention relates to a method for joining at least two flexible foils (10a-b). The method comprises the steps of (i) providing a first flexible foil (10a) having a first row (12) of light emitting diodes (14) and a first set of electrically conductive tracks (16) for supplying current to the first row (12) of light emitting diodes (14), (ii) providing a second flexible foil (10b) having a pot second row (12) of light emitting diodes (14) and a second set of electrically conductive tracks (16) for supplying current to the second row (12) of light emitting diodes (14), and (iii) joining the first flexible foil (10a) and the second flexible foil (10b) at an overlap (22) of the first flexible foil (10a) and the second flexible foil (10b), wherein a metal strip or wire (24; 24) gets embedded between the first flexible foil (10a) and the second flexible foil (10b) at the overlap, and wherein the metal strip or wire (24; 24) electrically connects to the first and second sets of electrically conductive tracks (16).
