[0017] Such as figure 1 As shown, the present invention mainly consists of a time base chip U, a triac VS, a potentiometer R8, a resistor R9, a resistor R10, a resistor R11, a resistor R12, a resistor R13, a resistor R14, an illuminating lamp EL, a diode D4, a diode D5, and a diode D6 , Capacitor C5, capacitor C6, switch SB, lighting EL light-emitting diode VL, photosensitive circuit, voltage frequency processing circuit and surge voltage suppression circuit.
[0018] Wherein, the P pole of the diode D6 is grounded, and the N pole is connected to the second anode of the bidirectional thyristor VS after passing through the resistor R14. The resistor R13 is connected in series between the OUT pin of the time base chip U and the control electrode of the bidirectional thyristor VS. The resistor R12 is connected in series between the TRI pin and the RE pin of the time base chip U. The P pole of the diode D5 is connected to the RE pin of the time base chip U, and the N pole is con...
