3, circuit structure of the present invention is simple, is easy to realize, economical and practical.
Accompanying drawing explanation
Fig. 1 is circuit theory diagrams of the present invention.
Embodiment
Below in conjunction with embodiment and accompanying drawing, to the detailed description further of the present invention's do, but embodiments of the present invention are not limited thereto.
Embodiment 1:
A kind of automatic light control device being applicable to public arena as shown in Figure 1, comprises bridge rectifier and the lamp L being connected to bridge rectifier input, described lamp L is parallel with the second resistance R2; One output of described bridge rectifier is held with the A of controllable silicon VS by human induction switch S and is connected, and another output is connected on the K end of controllable silicon VS; The G end of described controllable silicon VS is connected on the source electrode of transistor T, A end, the K end of described controllable silicon VS are connected with the drain electrode of transistor T, source electrode respectively respectively by the first resistance R1, the 4th resistance R4, the K end of described controllable silicon VS is also connected with the grid of transistor T by electric capacity C, is connected with photo resistance R3 between the drain and gate of described transistor T.
As shown in Figure 1, bridge rectifier is made up of diode D1-D4.The prerequisite of whole circuit working be the shutoff of human induction switch whether.When human induction switch S has monitored people, human induction switch S connects, civil power is after bridge rectifier rectification, and the voltage be added between the A end of controllable silicon VS and K end is a pulse voltage, supplies follow-up circuits for triggering as DC power supply and synchronizing voltage after resistance R1 step-down.In every half period, when the charging voltage on electric capacity C repeatedly arrives the peak point voltage of transistor, transistor turns, electric capacity C is by the 4th conductive discharge, now, the 4th resistance exports a pulse, delivers to silicon controlled G and hold, trigger controlled silicon conducting, now, lamp is shinny; After controlled silicon conducting, hold the pressure drop between G end very little at silicon controlled A, now, circuits for triggering quit work.When supply voltage zero passage, controllable silicon turns off, until next cycle starts, electric capacity charges again, successively said process repeatedly.In circuits for triggering circuit, adopt photo resistance to regulate the ON time of controllable silicon in every half period, thus control the brightness of lamp.When the resistance of photo resistance is large, namely photo resistance and the second resistant series gained resistance value are greatly, and the electric capacity needs longer charging interval could by controlled silicon conducting, and now, bulb is darker; Otherwise bulb is brighter.When human induction switch S monitors nobody, human induction switch S time delay disconnects, and after disconnection, subsequent conditioning circuit does not then work, and lamp does not work, and reaches the object of saves energy.Resistance R2 shields to lamp, avoids surge to the destruction of circuit.
Embodiment 2:
A kind of automatic light control device being applicable to public arena as shown in Figure 1, the present embodiment is optimized on the basis of above-described embodiment, and namely described human induction switch is human body infrared sensing switch.Human induction switch have based on microwave sensor, have based on infrared inductor.And based on microwave sensor, when unmanned or people's transfixion, namely human induction switch disconnects, in self-study classroom or library, obviously inapplicable.Adopt the human body infrared inductive switch based on infrared inductor, it can directly be monitored people, and no matter whether people is walking about, and it is widely applicable.
In order to improve the sensitivity of human body infrared inductive switch, described human body infrared inductive switch is TDL-2181R.
