Electronic Pest Killing Lamp (6)
When the power is on, alternating current 220V voltage will illuminate EL after the voltage is reduced by C1. The other circuit will provide VT's positive pole with working voltage, making VT work in the positive half period and stop working in the negative half period. T will generate pulse high voltage which will be put on the high voltage electric net after the voltage is rectified and reduced by VD2 and R3. When the pest touches the net, it will be killed by the high voltage.
