Abstract

An LED lighting apparatus of the invention includes a substrate having a length in a first direction and a width in a second direction. LED chips are supported on the substrate along the first direction. A light guide, having a thickness in the second direction, includes an incident surface, a reflective surface and an emitting surface. The incident surface faces in a third direction perpendicular to the first and second directions for receiving light emitted from the LED chips. The reflective surface spreads in the first and third directions and reflects light from the incident surface in the second direction. The emitting surface spreads in the first and third directions and allows light from the reflective surface to exit. The substrate is supported by a case that includes side plates around the light guide and a bottom plate connecting the side plates.
