Abstract
Lighting assembly comprises an optical fiber light guide panel member having a light conducting core cladded on opposite sides by cladding made of optically transparent material having a lower index of refraction than the light conducting core to cause total internal reflection of conducted light within the light conducting core at the core-cladding interface. Disruptions at one or more areas of the cladding cause conducted light within the light conducting core to be emitted from one or more areas of the panel member. Electrical circuitry is bonded to one or both sides of the cladding. One or more LEDs embedded in the panel member are in electrical conduct with the electrical circuitry and optically coupled to the light conducting core.
