Description of drawings
Fig. 1 is the electrical block diagram of the utility model.
Embodiment
Below in conjunction with Figure of description the utility model is further specified:
The light-controlled electronic switch; Bulb H is serially connected in the switching circuit; The input termination 220V civil power of rectifier bridge in this switching circuit; The positive pole of rectification bridge output end connects positive pole and resistance R 1 one ends of one-way SCR VS; The negative pole of rectification bridge output end connects negative pole, the end of adjustable resistance RP, the negative pole of photodiode D and the positive pole of voltage stabilizing didoe DW of one-way SCR VS; The other end of resistance R 1 connects collector electrode, an end of resistance R 2 and the negative pole of voltage stabilizing didoe DW of triode V, and the emitter of triode V connects the other end of adjustable resistance RP and the trigger end of one-way SCR VS, and the other end of resistance R 2 connects the base stage of triode V and the positive pole of photodiode D.Wherein, the model of one-way SCR VS is MCR100-6, and the model of voltage stabilizing didoe DW is 2CW55, and the model of triode V is 9014.
Operation principle: as shown in Figure 1, the 220V alternating current becomes dc pulse moving voltage after passing through bulb H and rectification full-bridge, as forward bias, is added on one-way SCR VS and the resistance branch; On daytime, brightness is greater than to a certain degree the time, and photodiode D presents low resistive state≤1K Ω; Triode V is ended, its emitter no current output, one-way SCR VS blocks because of the triggerless electric current; Flow through electric current≤2.2mA of bulb H this moment; Bulb H can not be luminous, and resistance R 1 makes triode V bias voltage be no more than 6.8V with voltage stabilizing didoe DW, and V shields to triode; At night, brightness is less than to a certain degree the time, and photodiode D presents high-impedance state>=100K Ω, makes triode V forward conduction, and emitter has the voltage of 0.8V approximately, makes one-way SCR VS triggering and conducting, and bulb H is luminous.Adjustable resistance RP is that element is selected in early morning or the brightness that realizes switch transition at dusk.
Installation and debugging: during installation; The printed board that dress is welded switching circuit is put into transparent plastic box and is fixed; It is connected with controlled electric light H, and let it face the space of becoming clear before the canopy of the heavens or the house light inlet window, avoid 3 meters direct irradiations with interior night lights.Debugging should be carried out during the dusk, regulates the size of adjustable resistance RP resistance, makes controlled electric light H initial point under appropriate brightness bright.
