[High-tech LED News] American Rambus company uses LED side-light light guide plate to embed micro-optical devices in the light-guide material to control the light-out angle, so as to obtain more light from the light guide, and the light-emitting efficiency reaches 92-95. %.
It is reported that even a simple collimator rarely achieves 90% light extraction efficiency. This technology will be used to provide lighting for professional areas of a certain area or orientation, such as offices, schools, retail stores and commercial buildings.
The photoconductive material is optically graded with polymethyl methacrylate (PMMA) and optically coupled with a mirror or lens cast at the edge of the light guide without the need to match the anti-reflective coating and index. The lens array that is placed on the surface of the light guide is optimally designed by a computer to meet the requirements of the light exit direction and to have suitable optical characteristics of the light guide.
