DEVICES, SYSTEMS, AND/OR METHODS FOR PROVIDING ILLUMINATION

摘要

An illumination system can provide and/or utilize a system comprising a first sheet (1400) formed of a light-diffusing material, said first sheet defining a pair of opposing faces (1410,1420) and two pairs of opposing edges (1430,1440), said first sheet adapted to provide a substantially uniform illumination from at least one (1410) of said faces when light is transmitted into any of said edges; a first reflective layer (1500) adapted to reflect light toward a second face of said pair of faces,- a second sheet (1700) formed of a light diffusing material; and a first light source (1210) adapted to transmit light into a first edge of said edges.
