Patent number: 11946616Abstract: A light engine and system are disclosed in which the light engine contains a core comprising an opening extending through opposing surfaces and a flexible printed circuit board (PCB). The PCB includes a flexible body disposed on an outside of the core and having independently addressable sets of illumination sources mounted thereto, and flexible legs extending from the body and through the opening. The legs are bent such that a terminal portion of each leg is substantially parallel to the opposing surfaces of the core. Independent control of the sets of illumination sources is provided via the legs. The body is separated into segments, each on a different section of the outside and containing body contacts electrically independent of the body contacts of each other segment. Each leg is associated with a different segment, and contains leg contacts on the terminal portion in electrical contact with the associated body contacts.Type: GrantFiled: December 7, 2020Date of Patent: April 2, 2024Assignee: Lumileds LLCInventors: Frederic Stephane Diana, Yifeng Qiu, Michael Wasilko, Nazila Soleimani, Jeroen Den Breejen, Alan Andrew McReynolds, Gregory Donald Guth

Patent number: 10868076Abstract: A light engine is disclosed in which the light engine contains a core having an opening extending completely therethrough and independently addressable LED segments. The opening defines an inner surface of the core. Each segment has LEDs and is attached to a flexible PCB. The PCB has a flexible body attached to one of an inner or outer surface of the core and to which the segments are mounted, and flexible legs extending from the body, along the core, and traverse and adjacent to the other of the inner or outer surface. A light guide plate (LGP) receives and guides light from the segments so that the light exits to provide illumination. The segments emit light in all directions of a plane created by the LGP. A reflector opposes and covers a top surface of the LGP and the segments and reflects light from the LGP back into the LGP.Type: GrantFiled: February 10, 2020Date of Patent: December 15, 2020Assignee: Lumileds LLCInventors: Frederic Stephane Diana, Yifeng Qiu, Michael Wasilko, Nazila Soleimani, Jeroen Den Breejen, Alan Andrew McReynolds, Gregory Donald Guth
