Abstract
A dimmable induction RF fluorescent light bulb comprising a power coupler with reduced extraneous electromagnetic radiation wherein a dimming facility utilizes burst-mode dimming that periodically interrupts the high frequency voltage and current to the power coupler with an off period and an on period in order to reduce the power being delivered to the power coupler wherein the off period is shorter than the time required for an electron density of the discharge within the lamp envelope to substantially decrease.
