Abstract:
A stepped light guide illumination system employing a planar sheet of an optically transmissive material having a stepped light guiding structure and one or more parallel arrays of channels. Light is input into the stepped light guiding structure using a number of light sources, such as LEDs, located within the channels and coupled to the stepped light guiding structure at multiple locations. Light is extracted from the stepped light guiding structure by two-dimensional patterns of light extraction features provided within the parallel channels and in surface areas of the stepped light guiding structure located between the parallel channels.

Claim (Index 18):
A backlight unit of an electronic display, comprising:\n a planar light guide defined by a rectangular sheet of an optically transmissive material having a first broad area surface, an opposing second broad area surface extending parallel to the first broad area surface and a light input edge configured for receiving light; a plurality of discrete optical couplers formed in the first surface and distributed along the light input edge according to a regular pattern, each of the plurality of discrete optical couplers having a highly elongated configuration and a tapered shape; a plurality of discrete LEDs sources disposed in registration with the plurality of discrete optical couplers and in a close proximity to the plurality of discrete optical couplers and the light input edge; a plurality of parallel ridges formed in the first surface and longitudinally extending perpendicular to the light input edge; a plurality of light extraction features formed in the second broad area surface, wherein each of the plurality of parallel ridges is configured to reflect light by means of a total internal reflection.
