Abstract
An induction RF fluorescent lamp, comprising a vitreous envelope filled with a working gas mixture, a power coupler comprising at least one winding of an electrical conductor for receiving an alternating voltage and current to generate an alternating magnetic field and thereby induce an alternating electric field within the lamp envelope, an electronic ballast providing appropriate voltage and current to the power coupler and a main mercury amalgam having a vapor pressure at room temperature which is higher than the vapor pressure of the mercury amalgam formed on the flag.
