An electrodeless fluorescent lamps was developed which is dimmable to 5%. Smooth dimming was achieved by rapid duty cycling in the lamp's 13.56MHz RF power.Flicker-free illumination at all power levels was achieved by simply modulating the duty ratio thanks to the lamp's nearly instantaneous power-cycle response when driven at 13.56MHz. Electrodeless fluorescent lamps feature an extremely long life since they do not suffer from electrode wear, and rapid power switching response without the delays associated with electrode warm-up and cooling. The high luminous intensity,rapid power switching response and dimming capabilities provide versatility for illuminated signs and decorative illumination use.
