Systems are generally described that include a curved light guide for thin structure illumination. An example system includes a light sub-assembly comprising a curved light sub-assembly backing ring and a plurality of light-emitting diodes (LEDs), each LED of the plurality of LEDs being coupled to the curved light sub-assembly backing ring. The example system also includes a curved light guide having an edge coupled to the light sub-assembly, the curved light guide including a pattern of optical extraction features that distribute light and are positioned on the exterior surface of the curved light guide for uniformly distributing light from the plurality of LEDs. The example system also includes a curved reflector including an exterior surface coupled to an interior surface of the curved light guide, wherein the exterior surface is reflective, and a volumetric diffuser coupled to the exterior surface of the curved light guide.
