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.

The present invention is a microwave excited electrodeless bulb and a process of generating ultraviolet light with a microwave excited electrodeless bulb. A process of generating ultraviolet light with a microwave excited electrodeless bulb in accordance with the invention includes providing an electrodeless bulb ( ) with an envelope ( ) containing an ultraviolet emissive material which emits ultraviolet light in response to microwave excitation. The envelope is filled with an ultraviolet emissive material. The envelope has a major internal dimension ( ) between and &lgr; to which a strong field of the microwave excitation is coupled during emission of ultraviolet light with &lgr; being the free space wavelength of the microwave excitation which varies between 2.4 and 2.5 GHz. The strong field is produced by a microwave source having a steady state rated output power of no greater than 0.85 kW. The bulb is rotated at a rotational velocity of at least 20 revolutions per minute. Ultraviolet emission occurs in selected ranges between 200 and 300 nm while a stream of air is directed in contact with the rotating bulb to provide cooling thereof.

Microwave-powered ultraviolet rotating lamp, and process of use thereof

A compact, electrodeless, microwave-powered lamp (e.g., ultraviolet light emitting lamp) is provided, as well as methods of using this lamp. The lamp includes a microwave generator, waveguide and RF cavity. The RF slot between the waveguide and RF cavity, for introducing microwaves from the waveguide into the RF cavity, extends through an end member forming the RF cavity rather than through the elliptical-shaped reflector; and the RF slot is aligned with the bulb. Cooling air for cooling the bulb passes through the RF slot, and preferably this cooling air passes by both the bulb and microwave generator for cooling both. The bulb is rotated during use. The compact size of the lamp facilitates its use in small devices, such as inkjet printers for office use to cure ultraviolet light curable inkjet inks, among other uses.

Compact microwave-powered lamp, inkjet printer using this lamp, and ultraviolet light curing using this lamp

An UV oven comprises a compact longitudinal elliptical reflector with first and second focal lines; a longitudinal small diameter bulb disposed along the first focal line that generates short wavelength UV radiation, IR radiation, visible radiation and heat to cure the coating on magnet wires or wire-like elements that are passed through the other focal line. The inside surface of the reflector is coated with material to enhance the reflectivity of the short wavelength UV, IR and visible radiation.
