ABSTRACT:
Apparatus for inactivating the source of microwaves for an electrodeless lamp to prevent accidental release of microwaves into the environment as a result of failure to assemble the lamp with a conductive mesh. An electrodeless lamp which is provided with a gas manifold for directing a stream of cooling gas against a lamp envelope is provided with a gas leak passageway which is blocked when the conductive mesh assembly is in place. A pressure switch in fluid communication with the gas manifold is activated and prevents operation of the microwave source when pressure is reduced as a result of gas leaking through the gas leak passageway.
