Abstract
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.
