Abstract
An electrodeless lamp which couples to a small bulb and obtains a relatively high light output therefrom. A cavity which comprises a compound resonant structure including vestibule and reflector portions is provided. The combination of vestibule and reflector results in a condition of resonance throughout the cavity, whereby strong fields are coupled to the small bulb and a reflector is provided for directing and enhancing light output.
