ABSTRACT:
An electrical circuit is provided for operating a combination insect electrocution grid and outdoor lamp. The circuit of the invention utilizes a high leakage reactance transformer in which a primary coil and two secondary coils are wound on a common core, the primary coil is centrally situated and the two secondaries are situated on opposite ends of the primary. A magnetic shunt is provided in the transformer between the primary and the high voltage secondary coil. A peaking capacitor, selected to induce the power frequency to resonate at the third harmonic, is connected to the high voltage secondary coil to generate the high voltage which energizes the electrocution grid. The other secondary coil is a ballast secondary which energizes the illumination means.
