Operation principle:
Shown in line such as X frame, AC220V(L) connected with rectifier bridge one end by load LAMP, the rectifier bridge other end and AC220V(N) connect.
When storing transport because of not accessing 220V power supply, so resistance R2 two ends no-voltage, and then the grid of field effect transistor Q4 is also at zero potential state, the cut-off of field effect transistor Q4, accumulator E discharge off loop, the not power consumption of accumulator E.When accessing 220V power supply, resistance R2, filter capacitor C1, protection Zener diode D5 provide forward bias voltage for field effect transistor Q4, make field effect transistor Q4 turn on, and accumulator E provides running voltage to controlling parts；When outfan 2 foot of human inductor module U2 is low level, 7 jiaos of controller U1 are low level, and audion Q2 ends, field effect transistor Q1 turns on, controllable silicon D1 turns on, and electric current returns to the negative terminal of rectifier bridge (switch Guan Bi) through accumulator, charges for accumulator E simultaneously.Audion Q3, Zener diode D3 are charge protector；Electric capacity C2, resistance R5, diode D2 form delay circuit；When outfan 2 foot of human inductor module U2 is the 6 foot high potential that high level and the timing circuit that is made up of R5, C2 make controller U1,7 feet of controller U1 become high level through pull-up resistor R3, audion Q2 turns on, and field effect transistor Q1 is ended, and controllable silicon D1 ends (switch OFF).The resistance of resistance R1, R2 is very big (100M), is negligible at the ohmically leakage current of the two, therefore flows through without any electric current during switch OFF, complete switches off.
