Working Principle: As seen in the figure 4-187, the circuit consists of power circuit, pulse oscillator and high voltage generator. The power circuit consists of S,FU,TI,VD1-VD4,C1,C3,IC1,R1 and VL. The pulse oscillator consists of IC1,R2,R3,RP1 and C2. The high voltage generator consists of V1,V2,RP2,RP3,R4,R5,T2. EL is the trap lamp and C5 is reduction voltage capacitor. When S is on, 220V voltage will illuminate EL. The other circuit will provide the pulse oscilator and high voltage generator with +12V working power after reduction, rectification, filtering by T1,VD1-VD4,C1. The voltage which is rectified will illuminate VLA.
