  • Electronic insect killer
    Patent number: 4387529
    Abstract: An electronic insect killer has spaced electrodes adapted to be electrically contacted by bodies of insects, said electrodes surrounding fluorescent lamps which attract the insects toward the electrodes. Interconnected with the electrodes and the fluorescent lamps is a solid state inverter which provides a high AC voltage at high frequency which is rectified to provide a high DC voltage across the electrodes, as well as lower AC voltage at high frequency for energizing the lamps without ballasting.
