Abstract
A light transmitting panel includes a lighting device and a light guide layer. The lighting device emits an input light. The light guide layer is formed from a phase separated glass material that includes a first material phase and a second material phase, wherein the first material phase functions to guide the input light along the light guide layer and the second material phase functions to scatter the input light so that at least part of the input light is directed out of the light guide layer as an output light.
