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.
Claims9
An electronic insect killer comprising a plurality of spaced electrodes adapted to be electrically contacted by the bodies of insects, means for attracting insects toward said electrodes comprising at least one fluorescent lamp, and solid state circuitry interconnected with said electrodes and also with said lamp for providing both a high voltage and a lower voltage at a high AC frequency, said high voltage being supplied across said electrodes and said lower voltage being supplied to said lamp for ballast-free energization of said lamp said high voltage being DC.
An electronic insect killer comprising a plurality of spaced electrodes adapted to be electrically contacted by the bodies of insects, means for attracting insects toward said electrodes, and solid state circuitry, including transistor switching means and a high frequency transformer having a primary winding, provided with current by said switching means, and a secondary winding, for providing a high AC voltage, means for rectifying said high AC voltage to provide a high DC voltage for insect electrocution, said means for attracting insects comprising at least one fluorescent lamp, said transformer having a further secondary winding for providing a lower AC voltage at high frequency to said lamp for ballast-free energization of said lamp, said electrodes surrounding said lamp, and means for supplying said high DC voltage across said electrodes.
