Operation principle of the present utility model is：The voltage that outside provides is added separately to triode Q1 collection through resistance R1 and R2
Electrode and base stage, Q1 is set to obtain base current, so that Q1 is turned on；
After voltage is filtered by electric capacity C1 again by diode D1, form steady dc voltage, after by Lp be added in Q4's
Drain electrode, electric current flows through by R1, Q1 pole electrode Ic1 after Q1 is turned on, and because Q1, Q2 base stage are connected on same point, so again
Q2 is given to obtain base current, if Q1, Q2 β, 200 or so, Q1, Q2 saturation conduction, Q1 colelctor electrode are changed into low electricity from height
It is flat.And then low level is changed into high level to Q2 colelctor electrode, so as to provide a conducting voltage to Q4 control pole, turn on Q4；
After Q4 conductings, source current is flowed through by primary LP, and ground, i.e. shape are flowed to Q4 drain electrode, then to Q4 source electrode and R7
Into a loop, because of the primary LP for thering is electric current to flow through transformer, therefore induced electromotive force will be produced in LP, and to C5 and transformation
Device secondary LS charges, and after certain voltage is charged to, just forms a voltage difference in lamp tube ends, with voltage difference increasingly
Greatly, so as to puncture the fluorescent material in fluorescent tube, lamp luminescence is made to work；
Due to Q2 current collection extremely high level, therefore electric current charges by R3 to C2, as the charging interval increases, D6 positive poles
Terminal potential constantly rises.After D6 positive poles terminal voltage is more than setting voltage, Q3 is changed into turning on from ending, and Q2 base stage becomes low
Level, so as to cause Q2 to end, Q2 cut-offs, Q4, which also becomes low level, and then to be ended, due to transformer T1 induced electromotive force
It can not be mutated, therefore lamp tube power supply is still given in T1 induced electromotive force, fluorescent tube is worked on luminous；When Q3 continues to turn on
Afterwards, C2 begins through R4, Q3 base stage electric discharge, and after discharge voltage is less than setting voltage, Q3 is changed into ending from turning on, Ran Houzai
Mode of operation during firm beginning occurs, then starts to repeat said process.
