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 1):
An illumination system, comprising:\n a first planar sheet of an optically transmissive material defined by a first broad-area surface configured for light output and an opposing second broad-area surface, the first planar sheet is configured for guiding light along a prevalent plane of the first planar sheet; a plurality of second planar sheets of an optically transmissive material attached to the second broad-area surface and spaced apart from each other by non-zero spacing distances; a first plurality of light extraction features formed in the second broad-area surface of the first sheet in spaces between the plurality of second planar sheets; a second plurality of light extraction features formed in a surface of at least one of the plurality of second planar sheets; and a plurality of LEDs optically coupled to an edge of at least one of the plurality of second planar sheets.
