Abstract
A light engine is disclosed in which the light engine contains a core comprising an opening extending completely through the core and independently addressable LED segments. The opening defines an inner surface of the core. Each segment has multiple LEDs. A PCB contains a body adjacent to one of an inner or outer surface of the core and to which the LED segments are attached and legs extending from the body and bent to be adjacent and traverse to the other of the inner or outer surface. Each leg is associated with a different LED segment. Control circuitry is connected with the legs of the flexible PCB and independently controls parameters of the LED segments to provide a preset illumination distribution and intensity based on user input.
