Microwave powered lamp with improved cooling system

Abstract

A air provided microwave powered lamp (100) and an assembly (300) of a microwave powered lamp. A microwave, powered lamp includes a housing (22) containing a water cooled magnetron (110), the water cooled magnetron providing microwaves to a microwave excited bulb, the microwave excited bulb 16 providing light from the housing; an air source (18), coupled to the housing, which blows air (20) to the water cooled magnetron and the lamp with the air providing cooling to the bulb to control operation temperature thereof; a heat exchanger (102), 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 (104), 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,
