The electronic pests killing lamp circuit consists of the power switch S, trap lamp HL, high-voltage electrode, capacitors C1 ~ C5 and diodes VD1 ~ VD5, and the circuit is shown as the chart. In the circuit, C1 ~ C5 and VDI ~ VD5 form the 5 times voltage doubling rectifying circuit. Turning on the power switch s will make HL get power and light, and the AC 220V voltage which is 5 times doubled rectified by the voltage rectifier circuit can generate the DC pulse voltage with about 1400V, which is added to the high-voltage electrode. When the insects fly to trap lamp, touch or near high-voltage electrodes, they will be killed by high voltage electrodes. C1 ~ C5 select polyester or CBB capacitors with the voltage being 630Y. VD1 ~ VD5 use 1N4007 silicon rectifier diodes. S uses 3 ~ 5A, 220V AC power switch. HL uses black light or special anti-mosquito lamp.
