Abstract: The invention is a lighting system which produces visible and UV light. The system includes a light bulb (60) which emits light in response to excitation by radio frequency energy; an electrically powered bulb rotation motor (50) mechanically coupled to the light bulb which rotates the light bulb coupled thereto; an electrically energized radio frequency energy source (70) which provides the radio frequency energy coupled to the light bulb, the electrically energized radio frequency energy source including a heater (110) which is energized at least while the radio frequency energy source is turned on; and a control circuit (24), for coupling to an electrical power source, which controls application of a regulated voltage to the heater and the bulb rotation motor.

Abstract: An electrodeless lamp comprises an envelope containing a fill and a substance for facilitating the starting of the lamp. An outer tube is secured to an outside portion of the envelope in proximity to the given region and an inner tube is disposed within the outer tube such that a fluid passageway is defined between an inner surface of the outer tube and an outer surface of the inner tube. A hollow retractable electrode is provided within the inner tube, the electrode having a first position in which its tip portion is in proximity to the given region of the envelope when the lamp is being started and a second position in which the tip portion is away from the envelope after the lamp is started. A source of cooling fluid is operably connected to the hollow electrode such that the cooling fluid is forced through the hollow electrode and exhausted through the fluid passageway.
