摘要： An incandescent bulb for use in a submerged swimming pool light fixture is disclosed, which includes a filament, at least one spring-biased filament support, and a grounding device. The filament support includes an exposed current-conducting portion and is moveable in response to the spring bias. The current-conducting portion of the filament support is arranged to allow it to come into electrical contact with the grounding device when the filament support moves in response to the bias of the spring. The filament is disposed to prevent movement of the filament support when the filament is intact and the lamp is in normal operating condition. When the filament is broken or is otherwise caused to release the filament support arms, the arms are free to move in response to the spring bias, causing the current-conducting portion of the arm to contact the grounding device, thereby providing a direct connection to ground for the incoming electrical current, and preventing escape of the current into the adjacent pool water.
