Brief description of the drawings
Fig. 1 is the circuit structure schematic diagram of the utility model.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in Figure 1：The utility model includes first resistor R1 to the 5th resistance R5, the first photo resistance RG1, the second light
Quick resistance RG2, the first triode VT1 to the 3rd triode VT3, capacitance C, battery E and relay K, battery E cathode at the same time with
The first end of capacitance C, the first end of relay K, the first end of the 5th resistance R5, the collector and the 3rd of the first triode VT1
The first end connection of resistance R3, the anode of battery the E second end with capacitance C, the emitter of the 3rd triode VT3, second at the same time
The emitter of triode VT2, the first end of second resistance R2 are connected with the first end of first resistor R1, the second end of relay K
Be connected at the same time with the first end of the 4th resistance R4 and the collector of the 3rd triode VT3, the base stage of the 3rd triode VT3 and meanwhile with
The collector connection of the second end of 5th resistance R5, the emitter of the first triode VT1 and the second triode VT2, the two or three pole
The base stage of pipe VT2 while first with the second end of the 4th resistance R4, the second end of second resistance R2 and the second photo resistance RG2
End connection, the base stage of the first triode VT1 connect with the second end of first resistor R1 and the first end of the first photo resistance RG1 at the same time
Connect, the second end of the first photo resistance RG1 connects with the second end of the second photo resistance RG2 and the second end of 3rd resistor R3 at the same time
Connect, the controlling switch of relay K（Not shown in figure）It is connected in the control loop of electrical appliance.
The operation principle of the utility model is as follows：
Battery E provides 12V power supplys after capacitance C filtering to circuit, and the 3rd triode VT3 is provided by the 5th resistance R5
Base current turns it on, and relay K obtains electric actuation, its normally opened contact（Not shown in figure）Closure, connects load electrical appliance electricity
Source, since the 3rd triode VT3 is turned on, its collector potential is very low, and the second triode VT2 without enough base bias currents because cutting
Only, therefore the 3rd triode VT3 maintains conducting state, and relay K is attracted always, when using illumination（It can be flashlight）Once
After two photo resistance RG2, its resistance value reduces, and through second resistance R2 partial pressures, is added in the bias increase of the second triode VT2 base stages,
And be enough to turn it on, so that the 3rd triode VT3 ends because without enough base biases, the release of relay K dead electricity, cuts
Disconnected electrical appliance power supply, the 3rd triode VT3 is once end, its collector is changed into high potential, even if illumination at this time is not irradiated to
On second photo resistance RG2, the second triode VT2 is also switched on, and to open power supply, is then needed with illumination once the first photosensitive electricity
RG1 is hindered, after being subject to illumination because the first photo resistance RG1, resistance value reduction, DC voltage is by first resistor R1 partial pressures, and the
One triode VT1 obtains enough base biases and turns on, and then the 3rd triode VT3 is because obtaining enough base biases again
Conducting, relay K is attracted again, and startup power supply.
The advantages of basic principle and main feature and the utility model of the utility model has been shown and described above.One's own profession
