Accompanying drawing explanation
Fig. 1 is the circuit diagram of public corridor lamp control circuit.
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 public corridor lamp control circuit, comprises rectifier bridge T, relay J, triode V1 and key switch K1, the contact J-1 of described relay J connects key switch K1, key switch K2, key switch Kn and 220V line voltage, the other end of the contact J-1 of relay J connects the other end of key switch K1, the other end of key switch K2, the other end of key switch Kn, resistance R1, the stiff end of electric capacity C1 and potentiometer RP1, the other end of other end contact resistance R1 of electric capacity C1 and the port one of rectifier bridge T, another stiff end of potentiometer RP1 connects sliding end and the light fixture L of potentiometer RP1, the other end of light fixture L connects the port 3 of rectifier bridge T and the other end of 220V line voltage, the other end of the port 2 contact resistance R2 of rectifier bridge T, resistance R2 connects electric capacity C2, the negative electrode of diode D1, the negative electrode of diode D2 and relay J, the other end of electric capacity C2 connects the anode of diode D1, resistance R4, the emitter of triode V3 and the port 4 of rectifier bridge T, the other end of relay J connects electric capacity C3, the anode of diode D2, the contact J-2 of relay J, the collector electrode of triode V1, the collector electrode of triode V2 and the collector electrode of triode V3, the other end contact resistance R3 of the contact J-2 of relay J, the other end of resistance R3 connects the other end of electric capacity C3 and the base stage of triode V1, the other end of emitter contact resistance R4 of triode V1 and the base stage of triode V2, the base stage of the emitter connecting triode V3 of triode V2.
The contact J-1 of relay J is normally opened contact, and the contact J-2 of relay J is normally-closed contact.
Operation principle of the present utility model is: when certain family to have people to go out elbow night, can click self-resetting button switch Kn(each household set outside this gate, family and all can arrange such self-resetting button switch outdoors greatly).So corridor street lamp L is lit.Meanwhile, electric capacity C1 is energized, and the low-voltage AC exported after current limliting, by after the rectification of rectifier bridge bridge, R2 current limliting, C2 filtering and voltage stabilizing didoe D1 voltage stabilizing, exports 12V direct voltage at C2 two ends.This voltage one tunnel adds to triode V1 base stage through relay J, relay normally-closed contact J-2, resistance R3.Another road of 12V voltage adds to the collector electrode of triode V1 ~ V3, and makes the rapid conducting of triode.Like this, relay Working winding will have electric current to flow through, and the normally opened contact J-1 of relay J closes, and substitute key switch Kn and self-locking, electric light L still continues to light.While relay normally open contact J-1 is closed, another normally-closed contact of relay J-2 disconnects, and has cut off triode V1 base stage positive bias voltage.But power supply still continues through relay Working winding to charge to electric capacity C3, because now V1 base current is very little.C3 both end voltage can not be suddenlyd change.Its current potential can only slowly raise, therefore (i.e. time delay) relay J still continues to keep attracting state during this period.Along with the further rising of C3 current potential, relay J both end voltage is fallen and is reduced gradually.When be down to be not enough to make relay to keep attracting state time, relay resets, and normally opened contact J-1 disconnects, electric light L power-off extinguishing, Cl power-off.Meanwhile, another normally-closed contact of relay J-2 closes.On C3 the loop that forms through normally-closed contact J-2, R3 of lotus of charging release rapidly, in order to the use of time delay of charging next time.By the brightness of the conveniently adjusted light fixture L of potentiometer RP1, the capacitance changing electric capacity C3 can change delay time.
