A luminaire assembly comprising at least one magnetron, a least one microwave-powered bulb, a luminaire reflector, at least one waveguide, and a radio-frequency screen assembly is provided. The radio-frequency screen assembly, the radio frequency gasket, and the luminaire reflector are configured to form a microwave cavity that can accommodate a microwave-powered bulb. The at least one waveguide is configured to couple energy from the at least one magnetron to the microwave-powered bulb. The radio-frequency screen accommodates at least one latching structure. The at least one latching structure is configured to sufficiently compress or to release the radio-frequency screen and the luminaire assembly. In another embodiment, a radio-frequency screen assembly comprises a frame which comprises an opening defined by a plurality of edges. The frame comprises a planar portion and further comprises a ridge at one of the edges that extends in a direction perpendicular to the planar portion.

Radio frequency screen assembly for microwave cavities

A luminaire reflector comprises a first end reflector segment, a second end reflector segment, and a main reflector segment bonded together as a single-piece. The main reflector segment, the first end reflector segment, and the second end reflector segment form a microwave cavity that can accommodate a microwave-powered bulb. The luminaire reflector is configured to be mated to at least one waveguide of a luminaire assembly. The luminaire reflector comprises at least one RF coupling slot to transmit microwave energy from the waveguide side to the microwave cavity side of the reflector assembly.

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