Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
nullRefer to Fig. 1，In this utility model embodiment，A kind of LED street lamp lighting controller，Including electric capacity C4、Resistance R4、Diode D1、Metal-oxide-semiconductor Q1 and potentiometer RP1，One end of described electric capacity C4 connects resistance R4、The anode of diode D1、The anode of diode D2、Resistance R1 and 220V alternating current，The negative electrode of diode D1 connects resistance R2，The other end of resistance R2 connects the drain electrode of metal-oxide-semiconductor Q1，The negative electrode of diode D2 connects resistance R3 and electric capacity C2，The other end of resistance R1 connects the sliding end of potentiometer RP1、The fixing end of of potentiometer RP1 and electric capacity C1，The other end of electric capacity C4 connects the other end of 220V alternating current、The other end of resistance R4、Electric capacity C2、Electric capacity C3、The anode of diode D3、The anode of diode D4、The emitter stage of audion V1 and LED lamp H，Another fixing end of potentiometer RP1 connects negative electrode and the base stage of audion V1 of diode D3，The other end of resistance R3 connects the negative electrode of diode D4、The colelctor electrode of audion V1 and the grid of metal-oxide-semiconductor Q1，The source electrode of metal-oxide-semiconductor Q1 connects the other end and the other end of LED group H of electric capacity C3.
Resistance R4 is varistor.
Operation principle of the present utility model is: after the line voltage of 220V first passes around electric capacity C4 filtering and varistor R4, then filters through D2 halfwave rectifier and electric capacity C2, and resistance R4 is varistor, is used for bypassing the moment overvoltage on electrical network, to protect late-class circuit.Direct-current working volts are provided for the grid of metal-oxide-semiconductor Q1 and the colelctor electrode of switching transistor V1.R1, RP1 form RC phase-shift network with electric capacity C1, and D3 is arranged for electric capacity C1 charge and discharge over the ground.The conducting of power switch MOSFET and shutoff, controlled by small-signal transistor V1.At the positive half cycle of line voltage, V1 is made to turn on by R1, RP1.During V1 turns on, Q1 turns off.Otherwise, when V1 ends, Q1 saturation conduction.The effect of diode D1 is to ensure that T1 only turns in the starting stage of the positive half cycle of Vac, forms needle-like pulse current and charges Large Copacity filter capacitor C3.RC phase-shift network produces a phase-shifting voltages, as long as and this voltage with input line voltage across zero cross point as starting point, phase-shifting voltages reach the threshold voltage of Q1, V1 then opens conducting, so that Q1 cut-off, the then charging termination to electric capacity C3.V1 turns off after power frequency civil power crosses zero cross point.Owing to the drain electrode of Q1 concatenates a commutation diode D1, therefore C3 can not be charged at line voltage negative half period.Although the needle-like pulse current narrower in width produced when Q1 turns on, that is the shortest to the charging interval of C3, but owing to the capacity of C3 is very large, discharge time constant is the biggest, in the case of voltage on C3 has just begun to decline because of electric discharge or has declined seldom, Q1 turns on again, starts again to charge C3.Therefore, smoother VD can be produced at C3 two ends, be used for supplying LED street lamp and use.
