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: Apparatus for inactivating the source of microwaves for an electrodeless lamp to prevent accidental release of microwaves into the environment as a result of failure to assemble the lamp with a conductive mesh. An electrodeless lamp which is provided with a gas manifold for directing a stream of cooling gas against a lamp envelope is provided with a gas leak passageway which is blocked when the conductive mesh assembly is in place. A pressure switch in fluid communication with the gas manifold is activated and prevents operation of the microwave source when pressure is reduced as a result of gas leaking through the gas leak passageway.
