Abstract
An electrodeless lamp is excited by high frequency power in a termination fixture having an inner and an outer conductor, the lamp being located in the high field region at the end of the conductors. A source of ultraviolet radiation is located near the lamp and is activated momentarily when the lamp is to be excited. The radiation assists in initiating breakdown and excitation of the fill material in the lamp.
