ABSTRACT:
An electrodeless light bulb assembly including a case or housing supporting an electrodeless light bulb as well as a convection type heat exchanger. A solid state RF driver circuit is located inside the housing and connects to an excitation coil wrapped around the light bulb. The excitation coil comprises a metal heat pipe so as to provide an efficient thermal transport mechanism for the heat generated by the coil and the heat radiated thereto from the electrodeless bulb to the heat exchanger in addition to generating an RF excitation field for the electrodeless light bulb.
