ABSTRACT:
An electrodeless fluorescent lamp adapted for economical substitution in place of existing incandescent lamps comprises an ionizable medium contained within a phosphor coated globular envelope. A closed loop, magnetic core, which may be ferrite, is contained within the ionizable medium to induce an electric field, ionize the medium, and stimulate visible light output. The core, which may be coated with glassy material, is energized by a radio frequency power source in the lamp base structure. Current from the power supply is transmitted to the core by means of a metal rod structure which also serves to transfer heat from within the envelope. A secondary winding on the core provides high starting voltages to initiate a glow discharge.
