Patent number: 11359774Abstract: 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.Type: GrantFiled: July 18, 2018Date of Patent: June 14, 2022Assignee: Lumileds LLCInventors: Christian Kleijnen, Barbara Muelders, Lex Kosowsky, Manuel Grave, Udo Karbowski, Georg Henninger, S.

Patent number: 9053844Abstract: An electrical device that includes a first electrode and a second electrode that are separated from one another so as to form a gap structure. A layer of protective material spans the gap structure to contact the first electrode and the second electrode.

Patent number: 9007165Abstract: A substrate device includes an embedded layer of VSD material that overlays a conductive element or layer to provide a ground. An electrode, connected to circuit elements that are to be protected, extends into the thickness of the substrate to make contact with the VSD layer. When the circuit elements are operated under normal voltages, the VSD layer is dielectric and not connected to ground. When a transient electrical event occurs on the circuit elements, the VSD layer switches instantly to a conductive state, so that the first electrode is connected to ground.Type: GrantFiled: June 15, 2012Date of Patent: April 14, 2015Assignee: Littelfuse, Inc.Inventors: Lex Kosowsky, Robert Fleming, Bhret Graydon
