Abstract

A method for producing a flexible lighting strip comprising multitude of functional elements, which are light-emitting diodes, comprise light-emitting diodes, or are interposers with light-emitting diodes. The functional elements are in at least two groups, each comprising at least two functional elements in electrical series connection. The groups are in an electrical circuit having at least an anode and a cathode track as outer lines. The functional elements are in an electrical parallel connection to the anode and cathode tracks. The groups are in a longitudinal arrangement so a first group's last functional element is next to a second group's first functional element. Each of the outer lines has a wire line having substantially circular wires that are bent building zones capable of receiving compressive and tensile stress. The electrical circuit provides a third wire line having a substantially circular wire as a center line arranged between the outer lines.
