摘要： A flexible lighting strip (100) comprising a multitude of LEDs (22) which arranged in at least two groups, each comprising at least two LEDs (22) connected series. The at least two groups of LEDs (22) are arranged in parallel to at least an anode track (12) and a cathode track (14) as outer lines (12,14). A last LED (22) of a first group is arranged next to a first LED (22) of a second group. Each of the outer lines (12, 14) consists of a substantially circular wire (30) being bend building zones. A third wire line (15) having a substantially circular wire (30) is arranged between the outer lines (12, 14) that are able to receive compressive and/or tensile stress. At least one LED (22) of every group is mounted on an interposer (24), whereby the interposer (24) contacts all three wire lines (12, 14, 15).

摘要： The invention describes a method for producing a flexible lighting strip (100) comprising a multitude of functional elements (21) in a longitudinal arrangement. The functional elements (21) comprise light-emitting diodes (22). In one alternative, the functional elements (21) may be light-emitting diodes (22) itself. In another alternative, the functional elements (21) may be interposers (24) with light-emitting diodes (22) mounted thereon. The functional elements (21) are arranged in at least two groups. Each group comprises at least two functional elements (21) arranged in an electrical series connection. The at least two groups are arranged in an electrical circuit having at least an anode track (12) and a cathode track (14) as outer lines (12, 14), wherein the at least two functional elements (21) are arranged in an electrical parallel connection to the anode track (12) and the cathode track (14). The at least two groups are arranged in a longitudinal arrangement such that a last functional element (21) of a first group is arranged next to a first functional element (21) of a second group. Each of the outer lines (12, 14) consists of a wire line having substantially circular wires (30), whereby the wires (30) of the outer lines (12, 14) are bent building zones that are capable to receive compressive and/or tensile stress. The electrical circuit provides a third wire line (15) having a substantially circular wire (30) as a center line arranged between the outer lines (12, 14). The method comprises the steps of soldering a first functional element (21) to a first wire segment and connecting of the at least one wire segment to a second functional element.
