WAVEGUIDE ILLUMINATION SYSTEM
20170212295 · 2017-07-27 ·

An illumination system employing a waveguide that receives and propagates light in response to transmission and total internal reflection. Light deflecting elements distributed along the propagation path incrementally change the out-of-plane angles of light rays and cause decoupling of portions of light from the waveguide at different distances from the light input edge or end. Light may escape from the waveguide into an intermediate layer at low out-of-plane angles and can be further redirected by light extraction features out of the system. In one embodiment, the illumination system is configured to emit collimated light. In one embodiment, the illumination system includes shallow surface relief features. In one embodiment, the light deflecting elements include forward-scattering particles distributed throughout the volume of the waveguide.
