Fig. 2 is a circuit diagram of the present utility model.
(5) embodiment
In the circuit diagram of Fig. 2, not gate F1-F5 adopts the anti-phase integrated circuit of CMOS type six not gates, and model is CD4069.Wherein F1, F2 are connected into flip and flop generator, and resistance R 1 and capacitor C 1 are connected into and discharge and recharge circuits for triggering, the time constant when its numerical values recited has determined switch.At ordinary times, when the F1 input is low level, the output high level, C1 is charged near supply voltage by R1, at this moment the F2 output low level.As long as click SB1, the high level of capacitor C 1 anode is added to the input of F1 and the output of F2, the flip and flop generator upset, F2 exports high level, and at this moment, the output of F1 is a low level, capacitor C 1 is just discharged by R1, make the C1 anode also be low level, as long as click SB1 again, at this moment, the low level of C1 anode is added to the input of F1, oppositely the back is a high level, and the F2 output low level has been overturn once flip and flop generator again.At this moment C1 begins charging by R1 again, for upset is next time prepared.So, whenever press SB1 one time, the output of F2 all can stably overturn once, i.e. high-low level conversion once.The break-make of back level circuits for triggering has just been controlled in the conversion of high-low level.
When F2 was output as low level, the luminous tube of integrated package CD is because of no forward current, and was not luminous, thus phototriode end, T2 base stage no current, T2 also is in cut-off state, because of the trigger electrode triggerless electric current of one-way SCR VS1, VS1 also is in cut-off state.When the output of F2 is high level, 1 pin of integrated package CD obtains forward current by D5, R8, make luminous tube luminous, thereby phototriode conducting among the integrated package CD, 4 pin that are integrated package CD are high level, the base stage of T2 also is a high level, the T2 conducting, and the trigger electrode of one-way SCR VS1 obtains the forward trigger current and conducting.Because the bridge rectifier D10 ac input end of 4 diode compositions has been connected between the trigger electrode and main electrode of bidirectional triode thyristor SCR1, the both positive and negative polarity of one-way SCR VS1 has been connected between the dc output end both positive and negative polarity of bridge rectifier, so the conducting whether conducting of VS1 has just determined bidirectional triode thyristor SCR1 whether.The synchronous triggering electric current is that the anode by bridge rectifier D10 obtains after R7 current limliting, W2 voltage stabilizing.So flow through the just trigger current of bidirectional triode thyristor SCR1 of D10.So the negative stream of disconnecting of this kind circuits for triggering only flows through bidirectional triode thyristor SCR1, and does not relate to other components and parts.
F3, F4 constitute synchronization control circuit, and F5 is a delay circuit.Usually, when SB2 did not press, F3, F4 all exported high level, because the existence of D7 and D8 so have only as F3, when the F4 output is low level, just can be sent variation to other circuit.When SB2 presses, the output of F3, F4 all becomes low level, one the tunnel delivers to the input of F5 through F3, D7, this moment, C4 charged rapidly by D7, after unclamping SB2, though the output of F3 has recovered high level, the electric charge of storing owing to C4 need slowly discharge by high value resistor R4, so the input of not gate F5 still is a low level.So lamp H can not extinguish at once, along with the discharge of C4, the input level of not gate F5 constantly raises, when rising to the threshold level of not gate, not gate F5 overturns, and output becomes low level, because of losing trigger current, controllable silicon turn-offs when alternating current zero crossing voluntarily, and electric light H extinguishes.The T1 base stage is delivered to through F4, D8 in another road, makes the T1 conducting, at this moment, no matter the F2 output level is high and low, all can make the output upset of F2 be low level.
Incoming call makes the initial state that at every turn powers up all be unified into a kind of state of shutoff from putting out circuit.This circuit is to be made of R2, R3 and C3.When cause powers up at every turn, all be earlier through the D1 rectification, after R6, the D2 current limliting, make C3 pass through R2 and charge rapidly, during charging, an of short duration low level pulse can appear in the anode of C3, this pulse is delivered to the T1 base stage by D9, makes the of short duration conducting of T1, at this moment, no matter F2 output level is that height is low, all can overturn is low level.Thereby after having realized powering up, switch all is to be in off state at every turn.
Power pack: the 220V power supply after load (bulb), by the D1 halfwave rectifier, R6 and D2 current limliting, the one road supplies with power-on reset circuit R2, C3.Another road is level after the D3 isolation is sent to, and by the W1 voltage stabilizing, after C6, the C2 filtering, supply control part divides whole.
