Abstract

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.
