Patent ID: 7518315

Claim:
An electrodeless plasma lamp comprising: a lamp body comprising a dielectric material having a dielectric constant greater than 2; an electrically conductive material forming an outer surface around the lamp body; a power source configured to provide power to the lamp body at about a resonant frequency for the lamp body; an electrodeless bulb containing a fill, the fill positioned within the lamp body to receive at least a portion of the power from the lamp body, the fill adapted to emit light when the power is received from the lamp body; the electrically conductive material including an opening in the outer surface; the bulb including at least a portion of light transmissive material recessed from the opening such that a light path is formed between the light transmissive material and the opening in the outer surface; and the light transmissive material positioned between the fill and the opening in the outer surface such that the light emitted from the fill is transmitted through the light transmissive material and out of the opening.
