The invention is a microwave powered lamp (). The lamp includes a light reflective cavity (); an electrodeless bulb () contained in the light reflective cavity () from which light is emitted when the electrodeless bulb is excited by microwaves; a magnetron () for providing the microwaves for exciting the electrodeless bulb; a waveguide () which couples the microwaves emitted by the magnetron to the light reflective cavity for exciting the electrodeless bulb; a housing () which contains the lamp; a detector () disposed within the housing, which detects the microwaves which are not coupled to the bulb during operation of the magnetron and outputs a signal indicative of a level of received microwaves; and a magnetron control (), coupled to the detector, which causes the magnetron to be turned off when a level of the signal indicates the level of received microwaves exceeds a threshold.

Microwave powered lamp with reliable detection of burned out light bulbs

A system and method are provided to power a plurality of magnetrons devices. The system may include a power supply device to power a first magnetron device, a second magnetron device and a third magnetron device. A control device may control (or apportion) an amount of current to each of the second and third magnetron devices.

Apparatus and method for powering multiple magnetrons using a single power supply

A lamp assembly in accordance with the invention includes an electrodeless bulb ( ) which is symmetrical about an axis ( ) and which contains a light emissive fill which emits light when the bulb is excited by a RF electrical field coupled to the fill; an electrically conductive coupler ( ) comprising a plurality of turns ( ) which are symmetrical about an axis of the electrically conductive coupler, the turns defining a volume ( ) that at least partially contains the bulb; and a conductor ( ) connected to a center portion of the electrically conductive coupler with connection of the conductor to the electrically conductive coupler providing a fixing of the coupler relative to the bulb which, when the conductor is connected to a source of RF electrical potential, conducts a RF current producing a RF electrical potential on the electrically conductive coupler that produces the RF electrical field coupled to the light emissive fill.

Radio frequency driven ultra-violet lamp

The present invention is a microwave excited lamp and a microwave gasket. A microwave excited lamp ( ) in accordance with the invention includes at least one microwave source ( ); a microwave structure ( ) comprising a metallic material to which microwaves are coupled from the microwave source; the microwave structure, including a reflector ( ) comprising the metallic material and containing a microwave excited bulb ( ) which emits light in response to coupling of microwave power thereto from the microwave source; and at least one microwave gasket ( ) which provides a microwave tight seal between a surface of the reflector and at least one other metallic part of the microwave structure with the gasket comprising the metallic material; and wherein during operation of the lamp a microwave current maxima flows on a surface of the gasket and the reflector.

Microwave powered UV lamp with improved RF gasket arrangement

A system and method are provided to power two magnetrons devices. The system may include a power supply device to power a first magnetron device and a second magnetron device. A control device may control an amount of current reaching at least the first magnetron device.

Dual magnetrons powered by a single power supply

A air provided microwave powered lamp ( ) and an assembly ( ) of a microwave powered lamp. A microwave, powered lamp includes a housing ( ) containing a water cooled magnetron ( ), the water cooled magnetron providing microwaves to a microwave excited bulb, the microwave excited bulb providing light from the housing; an air source ( ), coupled to the housing, which blows air ( ) to the water cooled magnetron and the lamp with the air providing cooling to the bulb to control operation temperature thereof; a heat exchanger ( ), disposed in the housing, with the air blown from the air source contacting the heat exchanger, the heat exchanger having a portion contacted by water heated by operation of the water cooled magnetron with the air blown from the air source cooling the heated water, and a water circulation circuit ( ), coupled to the water cooled magnetron and the portion of the heat exchanger, which circulates heated water from the water cooled magnetron to the portion of the heat exchanger and cooled water from the portion of the heat exchanger back to the water cooled magnetron,

Microwave powered lamp with improved cooling system

A microwave-powered lamp comprises a microwave source; a non-resonant microwave cavity operably coupled to the microwave source, the microwave cavity being substantially cylindrical about a centerline; an elongated bulb disposed along the centerline of the microwave cavity; and a reflector operably associated with the bulb to direct radiation generated by the bulb to a product being cured. The bulb may be enclosed by a solid barrier such that cooling gas used for the bulb is isolated from the curing environment. The microwave cavity is separate from the function of focusing the radiation output from the bulb so that changes to the optical system can be made without also modifying the microwave cavity.

Lamp with self-constricting plasma light source

An apparatus for treating material with radiant energy, comprises a first reflector having a first object focus disposed outside thereof; and a second reflector having a second object focus. The first reflector is disposed with respect to the second reflector such that the second object focus is disposed further away from the first reflector than the first object focus. A radiant energy source is disposed within the first reflector whereby radiant energy is directed to the first object focus. An auxiliary reflector is disposed at the first object focus whereby radiant energy from the source is reflected to the second reflector and thence to the second object focus where the material being treated is disposed, whereby the second object focus permits the product to be positioned farther than the first object focus.
