Accompanying drawing explanation
Fig. 1 is the circuit diagram of intelligent standby LED controller.
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 intelligent standby LED controller，Including rectifier bridge Q、Diode D1、Resistance R1、Electric capacity C1、Audion VT1 and one-way SCR VS，Described rectifier bridge Q pin 1 and pin 3 connect 220V alternating current two ends respectively，Rectifier bridge Q pin 2 connects diode D1 negative pole respectively、Resistance R1 and resistance R2，The resistance R1 other end connects electric capacity C1 and audion VT1 base stage respectively，Audion VT1 colelctor electrode connects the resistance R2 other end and audion VT2 base stage respectively，Audion VT2 colelctor electrode connecting luminous diode LED1 positive pole，LED 1 negative pole connects resistance R3，The resistance R3 other end connects the G pole of resistance R4 and one-way SCR VS respectively，The resistance R4 other end connects the A pole of accumulator battery E positive pole and one-way SCR VS respectively，The K pole connecting luminous diode LED2 positive pole of one-way SCR VS，LED 2 negative pole connects accumulator battery E negative pole respectively、Audion VT1 emitter stage、Audion VT2 emitter stage、The electric capacity C1 other end、Diode D1 positive pole and rectifier bridge Q pin 4；Described diode D1 is Zener diode.
nullOperation principle of the present utility model is: refer to Fig. 1,After 220V AC rectification bridge Q rectification，Amplify latter aspect through audion VT1 and audion VT2 again to power to LED 1，Charge on the other hand to accumulator battery E，Now，Due to audion VT2 current collection extremely low level，The i.e. G of one-way SCR VS extremely low level，One-way SCR VS is made to be off state，LED 2 will not be lighted，LED1 is now only had to light，Accumulator battery E is charged，Existence due to Zener diode D1，Accumulator battery E maximum charging voltage not can exceed that the voltage stabilizing value of D1，When 220V alternating current has a power failure suddenly，Because the capacity of filter capacitor C1 is less，Audion VT1 and audion VT2 ends immediately，Release the block to one-way SCR VS，The G pole of VS obtains forward trigger current by resistance R4 and turns on，Standby LED2 obtains electric lighting，LED 1 extinguishes because losing civil power.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this utility model in other specific forms.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than described above, it is intended that all changes fallen in the implication of equivalency and scope of claim included in this utility model.Should not be considered as limiting involved claim by any reference in claim.
In addition, it is to be understood that, although this specification is been described by according to embodiment, but the most each embodiment only comprises an independent technical scheme, this narrating mode of description is only for clarity sake, description should can also be formed, through appropriately combined, other embodiments that it will be appreciated by those skilled in the art that as an entirety, the technical scheme in each embodiment by those skilled in the art.
