Patent ID: RE43492

Claim:
An underwater light, comprising : an ordinarily watertight housing; an outer compartment within said housing, said outer compartment being subject to flooding by water flowing therein from outside said housing in the event said housing is no longer watertight; a current shield disposed within said outer compartment, said current shield at least partially defining an inner compartment within said outer compartment; housing, said current shield inhibiting a stray electrical current from escaping said inner compartment when said housing is no longer watertight and said inner compartment is subject to flooding by water flowing therein; a light emitter disposed within said inner compartment; a passageway communicating between said inner compartment and said outer compartment such that at least a portion of any water flooding said outer compartment can enter said inner compartment and come into contact with said light emitter; and and a conductor positioned so as to collect any and substantially all the stray electrical current that may be conducted from said inner compartment by water within said passageway , thereby reducing the risk of electrical shock presented by such the stray electrical current.
