A voltage detection system for detecting a stray voltage in pool water within a pool caused by an electrical fixture integral with a pool wall of the pool. The system comprises a pair of elongate conductive elements, with one of the elongate conductive elements having a detector electrode end and a terminal end, and with the other elongate conductive element having a reference electrode end and a terminal end. The detector electrode end is positioned adjacent to the electrical fixture and the reference electrode end is positioned on an opposite side of the pool and preferably a maximum distance from the detector electrode end. And, the terminal ends are connected to a microprocessor for determining if a voltage between the detector electrode end and reference electrode end is greater than a predetermined threshold voltage.

Stray voltage detection system for protecting against electric shock drowning

An LED bulb is described, comprising LEDs within a shell and a driver circuit to operate the LEDs at a plurality of brightness levels. The driver circuit comprises first and second inputs to receive AC, a neutral input, a converter circuit, first and second rectifier circuits, a detector circuit, and a processing circuit. The first rectifier circuit is connected to the first and neutral inputs and rectifies the AC received. The second rectifier circuit is connected to the second and neutral inputs and rectifies the AC received. The detector circuit is connected to the first and second rectifier circuits. The processing circuit has a first and a second processor input, and is connected to the detector circuit. The processing circuit produces a chop signal with a duty cycle based on whether the first or second input is hot. The converter circuit powers the LEDs based on the chop signal.
