Patent ID: 8405290

Claim:
A light source comprising: a lucent waveguide of solid dielectric material having: an at least partially light transmitting Faraday cage surrounding the waveguide, a bulb cavity within the waveguide and the Faraday cage and an antenna re-entrant within the waveguide and the Faraday cage and a bulb having a microwave excitable fill, the bulb being received in the bulb cavity; wherein the Faraday cage is further comprising: a solid portion extending across a back of the lucent waveguide to a transverse extent thereof; and a clamp clamping the solid portion and the waveguide together and connecting the solid portion to a light-transmitting, front portion of the Faraday cage; wherein the solid portion is reflective, for directing light forwards; wherein the lucent wave guide and the solid portion of the waveguide are complementarily shaped for emitted light focus; and wherein a front of the lucent waveguide is flat.
