Accompanying drawing explanation

Fig. 1 is the circuit diagram of the anti-interference delay illuminating lamp of high accuracy.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments. Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.

Referring to Fig. 1, the anti-interference delay illuminating lamp of a kind of high accuracy, including chip IC 1, resistance R7, one end of metal-oxide-semiconductor Q1 and light fixture H, described resistance R7 connects resistance R1, the sliding end of the fixing end of of potentiometer RP1 and potentiometer RP1, the other end of resistance R1 connects electric capacity C1, the pin 2 of chip IC 1 and the pin 6 of chip IC 1, the other end of resistance R1 connects electric capacity C1, electric capacity C2, resistance R3, resistance R4, resistance R5, resistance R6, light fixture H, the pin 4 of chip IC 1, the pin 8 of chip IC 1, the pin 12 of chip IC 1 and the pin 14 of chip IC 1, another fixing end of potentiometer RP1 connects electric capacity C2, resistance R2, the negative electrode of unidirectional thyristor Q1, the emitter stage of audion V1, the pin 1 of chip IC 1, the pin 5 of chip IC 1, the pin 7 of chip IC 1 and the pin 10 of chip IC 1, the pin 3 of chip IC 1 connects resistance R2, the base stage of audion V1 and the pin 9 of chip IC 2, the colelctor electrode of the other end connecting triode V1 of resistance R4 and the pin 6 of chip IC 2, the pin 1 of chip IC 2 connects the other end of resistance R3, the other end of electric capacity C3 connects the pin 2 of chip IC 2, the other end of resistance R5 connects the pin 3 of chip IC 2, the pin 13 of chip IC 2 connects the other end of resistance R6, the pin 8 of chip IC 2 connects the control pole of unidirectional thyristor Q1, the anode of unidirectional thyristor Q1 connects the other end of light fixture H, the model of described chip IC 1 is NE555, and the model of chip IC 2 is CD4541.

Resistance R7 is photoconductive resistance. Light fixture H is LED.

Operation principle of the present utility model is: the NE555 time base circuit in circuit is connected into Schmidt trigger, after the photoconductive resistance RC signal received is carried out shaping and power amplification, drives subsequent conditioning circuit. When having illumination daytime, its 3rd foot output low level, night is unglazed according to time output high level. CD4541 is in circuit as timing controlled.

On daytime, photoconductive resistance R7 resistance is only small, and by R7 and WR1 dividing potential drop, NE555 the 6th foot voltage, more than 2/3Vcc, makes the 3rd foot be output as low level, and audion V1 ends. CD4541 the 6th pin preset end is high level, and its internal counter resets and resets, and the 8th foot outfan is low level, and Q1 ends, and relay normally open gets an electric shock and disconnects, and its controlled circuit does not work.

When The night screen has hung down time, R7 resistance is gradually increased, and NE555 the 2nd foot current potential is gradually lowered, and when less than 1/3Vcc, the upset of NE555 the 3rd foot output end signal is high level.V1 base potential raises and turns on, and provides one to be become the negative hopping edge of low level pulse from high level to CD4541 the 6th foot, makes internal circuit start counting up, outfan the 8th foot output high level. Q1 turns on, and light fixture H lights luminescence.

R3 and C3 is the external oscillation resistance of CD4541 and oscillating capacitance, when, after a period of time, outfan the 8th foot becomes low level. Q1 ends, and light fixture H quits work. By changing the resistance of R3, timing length can be changed.

Moment on the daytime dimmed relay misoperation that is not result in that this circuit causes for external interference is made, because connect R1 and the C1 of NE555 the 2nd, 6 foot forms delay anti-jamming circuit, when R7 resistance moment increases, owing to electric capacity C1 both end voltage can not be suddenlyd change, thus keeping the 6th foot current potential to be basically unchanged, the 3rd foot output is still low level. Reach to prevent the purpose of instantaneous abrupt change.
