Abstract
The utility model discloses an automatic electrical light turn-off device belonging to the electricity class, in particular to a time delay power-off controller which controls the time length of light emission of an electrical light. The utility model is characterized in that both ends of the electrical light are connected with a time delay control circuit in parallel; the time delay control circuit comprises a relay, an amplifier, and a charger; a main circuit is connected in series with a sensitive switch and the normally open contact of the relay; the main circuit is connected with the electrical light; the sensitive switch is connected in parallel with the normally open contact of the relay. As s result, the electrical light is automatically turned off after being on for a while so that the phenomenon of normally on lights can be avoided in public places with the adoption of the utility model. Consequently, the utility model has the advantages of energy saving and long service life.
Description
The utility model belongs to electricity, specifically a kind of a kind of delay cut-off controller of controlling the electric light fluorescent lifetime.
At present, the electric light of installing as stair, lavatory etc. all is with a pulling switch control in public.Though this control mode is fairly simple, in case having forgotten, people turn off the light, just can cause altar lamp.So promptly cause waste of electric energy, and reduced the useful life of electric light.
The purpose of this utility model is the automatic pass modulator that a kind of electric light of designing in order to overcome above-mentioned deficiency can extinguish after bright a period of time automatically.
The utility model is achieved in that it is the delay cut-off control circuit that constitutes through transformer BT, full-wave rectifying circuit ZL electrical relay J, an amplifier T in parallel and charger C at the two ends of electric light S, the relay J of this delay control circuit is connected with the emitter of amplifier T, charger C links to each other with the base stage of amplifier T, and the collector electrode of amplifier T links to each other with power cathode; Sensitive switch K of series connection in electric light S circuit
2, sensitive switch K in parallel between the collector electrode of amplifier T and base stage
1, K
1, K
2Interlock; The normally open contact J of relay J
1C connects with charger, normally open contact J
2Be connected in parallel on K switch
2Two ends.As long as press sensitive switch K like this
1, K
2, circuit is just connected, and electric light S is luminous, relay J work, normally open contact J
1, J
2Closure, sensitive switch K
1, K
2After the disconnection, electric current is given charger C charging through the base stage of amplifier T, and charger C is filled back control circuit C outage, and relay J quits work, J
1, J
2Disconnect.The moment that next time, sensitive switch was connected, charger C discharges.So just reached the purpose that control electric light S cuts off the power supply and extinguishes automatically.
Fig. 1 is circuit theory diagrams of the present utility model;
Below in conjunction with accompanying drawing the utility model is elaborated: amplifier T of the present utility model, can select a triode T for use
1In order to reduce the current strength of base stage, prolong the charging interval of charger C, amplifier T adopts two-stage to amplify, and promptly uses two triode T
1, T
2, its T
1Base stage and T
2Emitter join T
2Base stage and collector electrode respectively with charger C and T
1Collector electrode connect.Charger C can adopt a capacitor, and in a single day the time-delay of this structural circuit is determined, then can not be regulated again.If the length of lighting time of the present utility model can be selected, can select 1 capacitor parallel connection that above capacity is different for use, at this moment at charger C and normally open contact J
1Between need selector switch K of series connection, selector switch K connects with that capacitor, power supply is just given that capacitor charging, the size of condenser capacity determines the time that electric light S turns on light.In order to guarantee that the electric energy that charges into charger C discharges fully after down circuitry, at the two ends of charger C in parallel one by normally closed interlock J
3Discharge circuit with resistance R is formed so also can solve sensitive switch K
1When moment connects, the charger C incomplete problem of discharging.For can be after turning on light, people can also control and turn off the light, at sensitive switch K of front series connection of the transformer BT of control circuit
3, sensitive switch K
3Be normally closed switch.Sensitive switch K
1, K
2Be normal open switch.Diode D is in parallel with relay J, and purpose is guard amplifier T.Capacitor C
5Strobe C

2, C
3, C
4For selecting capacitor, RD is a fuse.
Because the utility model utilizes the lighting time of better simply delay circuit control electric light, can effectively avoid the phenomenon of public arena altar lamp to take place, this control circuit also is to work in lighting time, consuming electric power is littler, therefore the utility model can reach saves energy, prolongs the electric light purpose in service life.
