Zusammenfassung:	An LED backlight system having a plurality of backlight segments including an integral light waveguide, each backlight segment supporting a sidelight emitting LED. A light guide having a rectangular shape, a flat top surface, and a curved lower surface defines a cavity having a top and sidewalls, with the sidelight emitting LED positioned in the cavity. At least one of a reflective layer and a top out-coupling structure can be positioned between the top of the cavity and the sidelight emitting LED.
