Abstract
A coil extension of the RF coupling coil, surrounding an electrodeless light bulb containing an inert gas and selected chemical elements, generates a voltage at the distal end thereof which is higher than that which appears across the RF coupling coil proper, and wherein the high voltage from the distal end of the coil extension is returned to the light bulb through a point contact electrode located in relatively close proximity to the low voltage end of the RF coupling coil.
