Publication number: 20230417387Abstract: A flexible three dimensional display assembly is provided. The flexible display assembly includes electrically interconnected light emitting elements, a flexible lattice fixture and a display bezel. The light emitting elements are electrically interconnected by a system of conductors. The light emitting elements are coupled to the flexible lattice fixture by an arrangement of structurally interconnected framing cells that receive pairs of the light emitting elements. The flexible lattice fixture is secured to the substrate of the display bezel such that the pairs of light emitting elements are maintained in optical alignment with corresponding pairs of apertures of the display bezel.Type: ApplicationFiled: June 23, 2023Publication date: December 28, 2023Applicant: LUMILEDS LLCInventors: Barbara Roswitha Mülders, Udo Karbowski

Patent number: 11121122Abstract: 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.Type: GrantFiled: July 18, 2019Date of Patent: September 14, 2021Assignee: Lumileds LLCInventors: Christian Kleijnen, Frank Gubbels, Barbara Roswitha Mülders, Georg Henninger, Florent Monestier
