Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

Refer to Fig. 1, a kind of LED light control street lamp life extending controller, comprise electric capacity C4, triode V1, unidirectional thyristor Q2 and LED group H, one end contact resistance R6 of described electric capacity C4 and 220V alternating current, the other end contact resistance R6 of electric capacity C4 and the port one of rectifier bridge T, the port 2 of rectifier bridge T connects electric capacity C1, resistance R1 and LED group H, the other end contact resistance R2 of resistance R1, the collector electrode of triode V1 and the negative electrode of diode D1, the anode of diode D1 connects electric capacity C2, the other end of electric capacity C1 connects electric capacity C2, electric capacity C3, the emitter of triode V1, the port 4 of rectifier bridge T and the negative electrode of unidirectional thyristor Q1, the other end contact resistance R3 of resistance R2, the other end of resistance R4 and electric capacity C3, the other end of resistance R3 connects the anode of diode D2, the negative electrode of diode D2 connects the anode of unidirectional thyristor Q1 and the other end of LED group H, the other end of resistance R4 connects bidirectional trigger diode Q1, the other end of bidirectional trigger diode Q1 connects the control pole of unidirectional thyristor Q2.

Triode V1 is phototriode.

Operation principle of the present utility model is: the right-hand part of circuit is made up of single-phase thyristor Q1, bidirectional trigger diode Q1 and auxiliary circuit R2, R4, C3, R1.During daytime, triode V1 conducting by illumination, unidirectional thyristor Q1 not conducting, LED group H does not work, close to time at dusk, light intensity decreasing, during conduction value lower than triode V1, triode V1 turns off, now electric capacity C3 is charged by resistance R1, and when C3 charging voltage reaches the trigger voltage 35V of Q1, Q1 punctures generation trigger impulse, make thyristor Q2 conducting, in lamp group H, have electric current to pass through.This part circuit is typical thyristor voltage regulation circuit.

The time constant be made up of R1, C2 is that the charging circuit of 10 ~ 20s makes to be increased with the voltage rise on C3 by the electric current of R2 by C3, thus the time making C3 reach the trigger voltage of Q1 will reduce to 1ms gradually from 8ms, and then make to increase to 165 ° of about 10s of this process by the voltage turn-on angle of white trifoliate orange lamp gradually by 30 °, white trifoliate orange lamp is lighted in this process gradually.The value of C3 is larger, and time of delay is longer, and when R3, D2 ensure that C2 discharges into 2V whenever turn on thyristors, after thyristor voltage zero-crossing switching, C3 restarts charging.The effect of D6 ensures that in circuit shown in figure below, A point voltage, not charging to C2 lower than during 30V, starts to avoid lamp group H the waits for too long that is energized.

When dawn, after light intensity reaches the conduction value of triode V1, triode V1 conducting, charged to C3 by R2 by C2, make thyristor Q1 can also conducting, along with the decline gradually of C2 voltage, the thyristor Q1 angle of flow reduces gradually, and lamp group H brightness is thereupon dimmed gradually, until turn off.
