IPC: F21V8/00

Abstract: A transparent illumination system and related light guide plate is provided. The system is configured to facilitate total internal reflection propagation of light through the light guide plate despite low index of refraction differences between the glass material of the light guide layer and the adjacent layer. The system includes a light source, such as a laser diode, and an optical element to fan out light from the light source in the plane of the light guide plate. The light guide plate includes internal light extraction features.
