Electronic pests killing lamp circuit diagram 4
The electronic pests killing lamp circuit consists of the oscillator, control circuit, high voltage generator, LED indicating circuit and power supply circuit, and the circuit is shown as the chart. The oscillator circuit is composed of the time-base integrated circuit IC, resistors R5 ~ R7, diodes VD10, VD11 and capacitors C7, C8. Power supply circuit is composed of the capacitors C5, C6, resistors R3, R4, rectifier diodes VD5 ~ YD8 and voltage regulator diode VS. Control circuit consists of diode VD9, relay K and the pin 3 internal circuit of IC. High-voltage generator circuit consists of the capacitors C1 ~ C4, rectifier diodes VDI ~ VD4, resistors R1, R2, and high-voltage grid (high voltage electrodes A, B). LED indicating circuit consists of the resistors R8, R9, and light-emitting diodes VL1, VL2. R1 and R2 select 2W metal film resistors; R3 and R4 select 1W metal film resistors.
