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.

摘要： The invention relates to a lighting device (10) and a manufacturing method especially therefor. LEDs (12a, 12b, 12c) are arranged at a distance from each other. A leadframe (20) comprising conductor segments is provided interconnecting the LEDs (12a, 12b, 12c). The LEDs (12a, 12b, 12c) each comprise an LED die (30) attached to one of the conductor segments of the leadframe (20). The LEDs (12a, 12b, 12c) further each comprise a holding element (22) disposed to hold at least two conductor segments of the leadframe (20) which are at least partially embedded within the holding element (22). In order to obtain good optical properties, the holding elements (22) do not cover the LED dies (30). In addition, one or more of the conductor segments of the leadframe (20) are configured to be bent such that the lighting device (10) may be shaped. According to the proposed manufacturing method of the lighting device (10), conductor segments of the leadframe (20) are provided and holding elements (22) are formed at a distance from each other on the leadframe (20), each at least partially embedding at least two conductor segments of the leadframe (20). Mounting portions (26) of at least three conductor segments of the leadframe (20) are not covered by the holding elements (22). LED dies (30) are attached to the mounting portions (26).
