Abstract
A half wavelength resonant cavity having inner and outer coaxial conductors is coupled at one end to a dc power source, and a gas discharge electrodeless lamp is disposed in the region between the conductors at the other end of the cavity. Repetitive bursts of radio frequency oscillations occur within the cavity, the oscillations causing breakdown of the fill material within the lamp to produce light.
