First end；The emitter of first triode connects the base stage of the second triode；The collector of second triode is connected to first
The collector of triode；First output terminal of the emitter connection rectification chip of the second triode；The second end of relay coil
Connect the second output terminal of rectification chip；
Further include first resistor and second resistance；Second resistance is photo resistance；First resistor and second resistance series connection, this
First output terminal of one end connection rectification chip of series circuit, the second of the other end connection rectification chip of this series circuit are defeated
Outlet；The anode connection first resistor of diode and the common end of second resistance；The cathode of diode connects the first triode
Base stage.
The advantageous effects of the utility model are：
The utility model can be realized time control, pass through dual-switch on the basis of light controls lamp switch
Control, achievees the purpose that power saving to greatest extent, while do not influence to use again.It, can suitable for places such as factory, duty room, corridors
It is easy to use with adjustment light.
Description of the drawings
Fig. 1 is the circuit diagram of the utility model.
Specific embodiment
Fig. 1 is the circuit diagram of the utility model.As shown in Figure 1, including illuminator L, time switch U1, transformer T, whole
Flow chip U2 and relay.
In the present embodiment, time switch U1 can use the time switch of model KF316T.Rectification chip U2 can be with
Use various types of commercially available bridge rectifiers, such as DB101 series.
Relay includes relay coil KA and relay switch K.Illuminator L connects with relay switch K, this series connection
The input terminal of the both ends connection time switch U1 of circuit.The simple both ends of the output terminal connection transformer T of time switch U1.Transformation
The input terminal of the secondary grade both ends connection rectification chip U2 of device T.The simple both ends of the both ends connection transformer T of relay switch K.
Further include the first triode Q1, the second triode Q2 and diode.The collector connection relay of first triode Q1
The first end of device coil KA.The emitter of first triode Q1 connects the base stage of the second triode Q2.The collection of second triode Q2
Electrode is connected to the collector of the first triode Q1.The first output of the emitter connection rectification chip U2 of second triode Q2
End.The second output terminal of the second end connection rectification chip U2 of relay coil KA.
Further include first resistor R1 and second resistance R2.Second resistance R2 is photo resistance.The effect of first resistor R1 is
For adjusting the sensitivity of photo resistance.First resistor R1 and second resistance R2 series connection, one end connection rectification of this series circuit
The first output terminal of chip U2, the second output terminal of the other end connection rectification chip U2 of this series circuit.The anode of diode
Connect the common end of first resistor R1 and second resistance R2.The cathode of diode connects the base stage of the first triode Q1.
When in use, it can prevent in a closed box, open one small as the second resistance R2 of photo resistance
Window for receiving ambient, can so that light control is sensitiveer in this way.
When illumination strong such as daytime period, second resistance R2 is irradiated by light, and resistance value becomes smaller, the
One triode Q1 and the second triode Q2 end, relay coil KA dead electricity, and relay switch K is disconnected, cut-out illuminator L
Power supply.When the illumination weak period, such as cloudy day or at night, the resistance value increase of second resistance R2, the first triode Q1 and
Second triode Q2 saturation conductions, relay coil KA obtain electric actuation, and relay switch K is connected, and illuminator L obtains power supply electricity
Amount.
Meanwhile when illuminator L is in the illumination weak period, while illumination is not needed on the time again
Period, such as the late into the night, when not needing to mankind's activity, time switch U1 can control the opening and closing of illuminator L, reach
The effect of time control is carried out while to the control of illumination.
Above-described is only the preferred embodiment of the utility model, and the utility model is not limited to above example.It can
To understand, what those skilled in the art directly exported or associated under the premise of the spirit and design for not departing from the utility model
Oher improvements and changes are considered as being included within the scope of protection of this utility model.
