Abstract
A light fixture for waveguided ambient light is described herein. In one embodiment, the light fixture includes an LED light source for emitting light rays, a waveguide optically coupled to the LED light source to receive and guide the emitted light rays from a proximal end of the waveguide to a distal end of the waveguide, a first indirect lighting surface configured to receive a first portion of the emitted light rays and reflect the first portion at a first distribution to produce a first ambient light source, and a second indirect lighting surface configured to receive a second portion of the emitted light rays and reflect the second portion at a second distribution to produce a second ambient light source.
