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.
