Abstract
The invention describes a flexible lighting strip comprising a multitude of light-emitting diodes arranged in at least two groups. Each group comprises at least two light-emitting diodes arranged in an electrical series connection. The at least two groups are arranged in parallel to an anode track and a cathode track. The at least two groups are arranged in a longitudinal arrangement such that a last light-emitting diode of a first group is arranged next to a first light-emitting diode of a second group. The anode track and the cathode track each consist of a wire line having substantially circular wires that are bent to receive compressive and/or tensile stress. The electrical circuit provides a third wire line having a substantially circular wire as a center line arranged between the outer lines. At least one light-emitting diode of every group is mounted on an interposer which contracts all three wire lines.
