Abstract: A light guide guides light from a light emitter that is adjacent to an aperture of an electronic device. The light is eventually emitted from the aperture, to thereby provide lighting. The light guide can include a plurality of prisms which can thereby permit reduction in the overall thickness of the electronic device.
