Patent abstract
A UV-C anti-fouling device that is coupled to power source using a single power supply wire. The device is AC powered, and is capacitively coupled to the conductive surface that is being protected, such as the hull of a ship. The device includes a plurality of UV-C LEDs that are either powered during half-cycles of the AC supply, or powered via individual rectifier circuits, such as a diode bridge, or Graetz bridge. A light guide optically extends the light from the UV-C LEDs. The arrangement is robust against shorts and opens, as well as external inflicted damage.
