1. An illumination structure comprising:
- a substantially non-fiber waveguide, the waveguide comprising;
a discrete in-coupling region for receiving light and comprising an optical element disposed therewithin,a discrete propagation region for propagating light and that is substantially free of the optical element, anda discrete out-coupling region for emitting light, the in-coupling, propagation, and out-coupling regions being spatially distinct, light entering the in-coupling region being substantially retained within the waveguide for emission from the out-coupling region.

Abstract
In one aspect, an illumination structure includes a substantially non-fiber waveguide, which itself includes a discrete in-coupling region for receiving light, a discrete propagation region for propagating light, and a discrete out-coupling region for emitting light.

17. A method of producing light, the method comprising:
-
providing a substantially non-fiber waveguide comprising; a discrete in-coupling region for receiving light comprising an optical element disposed therewithin, a discrete propagation region for propagating light and that is substantially free of the optical element, and a discrete out-coupling region for emitting light; and emitting light proximate the in-coupling region, whereby the light propagates through the propagation region with substantially no emission therefrom into the out-coupling region, and is emitted from the out-coupling region. - View Dependent Claims (22, 23, 24, 25)
