The first soft-start module 02, it is connected to connecting between end 2 and AC power live wire from dynamic load of the first load control module 01; Comprise contactor KM1 and time delay part that can control contactor KM1 timing closing; The normally opened contact of contactor KM1 is connected in parallel on the two ends of diode VD1.
In the first soft-start module, the time delay part circuit structure of control contactor KM1 timing closing is: comprise transformer T, rectifier bridge KBL, 555 timers, light-emitting diode VD1;
On high-tension side two lead-out terminals of transformer T connect respectively holding and AC power live wire from dynamic load series connection of load control module; The low-pressure side output of transformer T connect rectifier bridge KBL input, two lead-out terminals of rectifier bridge KBL be connected on respectively the first electrochemical capacitor two ends; The second electrochemical capacitor is connected in series the two ends that are connected in parallel on the first electrochemical capacitor after the first resistance, and the anode of the second electrochemical capacitor is connected with the anode of the first electrochemical capacitor;
555 timers are selected the mature modules product of prior art, its second pin and the 6th pin are all connected on the negative electrode of the second electrochemical capacitor, the 8th pin and the 4th pin are all connected on the anode of the second electrochemical capacitor, after an electric capacity of the 5th pin serial connection, connect the negative electrode of the first pin and the first electrochemical capacitor, then ground connection; One end of contactor KM1 coil connects the three-prong of 555 timers, other end ground connection; After light-emitting diode VD1 series resistance R2, be attempted by the two ends of contactor KM1 coil, and resistance R 2 is connected with luminous two anodes of taking over VD1.
In the time that ambient light is brighter, phototriode VT saturation conduction, is low resistance state, does not substantially have electric current to flow through and in extinguishing state on street lamp group H1～Hn; Bidirectional triode thyristor VS2 in the first load control module 01 and VS1 all can triggering and conducting, and the first soft-start module 02 is not worked.Only have in the time that the active load series connection end 2 of the first load control module has load (while being not Light Condition), the first load control module 01 just have electric current to flow through (just starting working) from dynamic load series connection end 1 load connecing (as the first soft-start module 02 the present embodiment).The access of load control module 01, makes this control circuit not have no-load loss, has reduced expending of electric energy.
In the time that the light of natural environment is darkened to a certain degree, phototriode VT cut-off is high-impedance state, and the AC supply voltage of access electrical network provides electric energy through fuse BX, current-limiting resistance R and diode VD to street lamp group.Because sealing in of the first diode VD is equivalent to halfwave rectifier, the voltage that makes to be added in lamp group that seals in of current-limiting resistance R has part landing simultaneously, make the voltage at street lamp group two ends lower than 0.45 × 220V=99V, now with low pressure, the filament of H1～Hn is carried out to preheating.Supply current is flowed through after street lamp group H1～Hn, enters the first load control module 01 through the active load series connection end 2 of the first load control module 01.Then first supply current charges to capacitor C 5 by resistance R 4, in the time that the voltage on C5 is charged to certain amplitude, can trigger bidirectional triode thyristor VS2 and VS1, and after VS1 conducting, the first soft-start module 02 is started working:
The power supply of the time delay part of control contactor KM1 timing closing is supplied with after by transformer T transformation, rectifier bridge KBL rectification, the first electrochemical capacitor C1 filtering.Now 2 of ic 555 timer, 6 pin are high level, therefore 3 pin of 555 timers are still low level, contactor coil KM1 is in release condition.As time goes on, power supply slowly charges to C2 by R1, makes the potential difference at C2 two ends increasing, and 2 of 555 timers, 6 pin current potentials are more and more lower.When 2,6 pin voltages of 555 timers are during lower than 1/3 supply voltage, 555 timers trigger set immediately, now 3 pin of 555 timers are high level by original low transition, the adhesive of contactor KM1 excitation, its normally opened contact KM1 closure, make the first diode VD by short circuit, illuminating street lamp group H1～Hn starts total head work.The delay time of the first soft-start module is definite by the numerical value of C2, R1, and the while, the secondary voltage of T declined to some extent because the first diode VD and current-limiting resistance R's seals in, and should note the magnitude of voltage of T level while selecting.VD by short circuit after, the secondary voltage of T also can increase, but therefore applied voltage wider range (5～15V) of 555 timers can adapt to this variation completely.
In conjunction with Fig. 3 and Fig. 4, the second specific embodiment structure of the present invention is, on the architecture basics of the first embodiment, increase standby lighting module, comprising the standby lighting street lamp L1～Ln and the second load control module 03 and the second soft-start module 04 that are connected in parallel in alternating current circuit.One end of standby lighting lamp L1～Ln connects AC power live wire, and the other end connects the active load series connection end 2 of the second load control module, and connects AC power zero line by the AC power zero line link 3 of the second load control module 03; The second soft-start module 04 is connected to connecting between end 1 and power firestreak from dynamic load of the second load control module 03; The circuit structure of the second load control module is identical with the circuit structure of the first load control module; The circuit structure of the second soft-start module is identical with the circuit structure of the first soft-start module, but comprises different contactor coil KM1 and KM11, and the second soft-start module 04 comprises contactor KM11 and time delay part that can control contactor KM11 timing closing;
