Abstract

An LED-based illumination system includes a layered optical sheet-form structure and a light source. The sheet-form structure comprises a first optically transmissive sheet with parallel channels formed in its first major surface. Each channel has a triangular cross-section with opposing planar walls configured for total internal reflection. A second optically transmissive sheet is bonded to the first sheet's surface using an optically transmissive adhesive, at least partially encapsulating the channels. An optically transmissive light diffusing sheet is provided as part of the sheet-form structure. The second sheet's outer surface has light deflecting microstructures. The light source comprises multiple LEDs configured to illuminate the layered structure at incidence angles from 0 to at least 75 degrees. The layered optical sheet-form structure may include additional features such as perpendicular channel arrays or specularly reflective side walls.
