LED-based edge lit illumination system
An edge lit illumination system is directed to providing backlighting utilizing a luminescent impregnated lightguide. The apparatus includes an LED radiation source providing a first radiation and a lightguide optically coupled to the LED radiation source including a luminescent material embedded or coated on an output surface of the lightguide designed to absorb the first radiation, and emit one or more radiations. The illumination system may further include additional optical components such as reflective layers, for directing radiation striking the back surfaces of the light guide back into the lightguide, as well as diffusion layers, UV reflectors, and polarizers.
