Abstract
A light engine system is disclosed in which the light engine system comprises a light engine. The light engine comprises independently addressable LED segments, each LED segment comprising LEDs and a flexible PCB to which the segments are attached. A light guide plate (LGP) is provided into which light from the segments is introduced, in which the light is guided, and from which the light exits to provide illumination. The segments emit light in all directions of a plane created by the LGP. A diffuser opposes a first surface of the LGP over substantially the entirety of the LGP. The diffuser diffuses light exiting the LGP into the environment away from the light engine.
