Abstract
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.
