ABSTRACT:
An excitation circuit for an electrodeless light bulb which includes an RF source, a driver amplifier, and a load matching network and where the frequency of the RF energy generated by the source is swept over a predetermined frequency range in a controlled manner by a programmable frequency controller to cover the entire range of possible load match tuning conditions so that the electrodeless bulb will be substantially matched at all times to the source at some frequency in the sweep range.
