Electric main is by being divided into two-way after illuminating lamp and rectification filtering module 100, and a road is Automatic level control mould
Block 500 is powered；Second tunnel is signal amplification module and trigger module confession after voltage transformation module 200 processes
Electricity.
When external environment condition illumination is strong by day, the resistance value of photoconductive resistance RG is the least, audion Q2's
Current collection extremely low level, audion Q2 is in cut-off state.Now the base stage of NPN type triode Q4 is
High level, NPN type triode Q4 is in saturation conduction state.Owing to the control end of IGCT Q1 is low
Level, IGCT Q1 is in cut-off state.Owing to the output voltage of rectification filtering module 100 is too high, shine
Bright lamp LP1 does not reaches rated operational voltage, and whole circuit does not works.
When night, external environment condition illumination died down, the resistance value of photoconductive resistance RG becomes big, audion Q2's
Colelctor electrode level raises, and whole circuit is all in treating standby state.If now there being acoustical signal to input mike
MK1, mike MK1 by acoustical signal be converted to the signal of telecommunication export audion Q2 base stage and by
Audion Q2 is amplified processing, and the signal of telecommunication after amplification triggers switching tube 100 through electric capacity C2 and turns on.
Once switching tube 100 turns on, and its input current potential becomes low level.Now electric current is by electric capacity C1 the second end
Flowing out, the first end flowing into electric capacity C1 through resistance R2, resistance R4 and voltage transformation module 200 is formed back
Road.NPN type triode Q4 flows out and reverse bias from base stage due to electric current, and NPN type triode Q4 is cut
Only.Owing to NPN type triode Q4 is ended, the control end of IGCT Q1 becomes high level, IGCT
Q1 turns on.Meanwhile, the output voltage of rectification filtering module 100 also becomes low level, illuminating lamp LP1 because of
Reach rated operational voltage and be lit.
After illuminating lamp LP1 is lit, even if the trigger voltage that switching tube 100 controls end disappears, its input
End still can keep low level to make Q1 be constantly in conducting state.Discharge loop resistance due to electric capacity C1
Value is very big, so discharge process is longer.When the electric energy stored by electric capacity C1 discharges completely, electric current flows again
Entering the base stage of NPN type triode Q4, NPN type triode Q4 turns on again, and IGCT Q1 enters
Cut-off state, illuminating lamp LP1 quits work immediately.The most whole circuit is in again treats standby state, under wait
Secondary it is triggered.
The another object of the embodiment of the present invention also resides in a kind of lighting including above-mentioned lighting circuit of offer.
The embodiment of the present invention is by possessing illuminating lamp LP1, rectification filtering module 100 and voltage conversion
In the lighting circuit of module 200 increase mike MK1, signal amplification module 300, photoconductive resistance RG,
Trigger module 400, electric capacity C1 and level control block 500, by photoconductive resistance according to external light intensity
Adjusting resistance value with the work of control signal amplification module or to end, acoustical signal is converted to by mike MK1
The signal of telecommunication, the signal of telecommunication is operationally done processing and amplifying by signal amplification module 300, and trigger module 400 is connecing
Trigger signal to electric capacity C1 output when receiving the signal of telecommunication, electric capacity C1 when receiving triggering signal to level
Control module 500 output current signal, and be charged after electric discharge terminates, level control block 500 exists
The outfan maintaining rectification filtering module 100 during the non-output current signal of electric capacity C1 is high level, at electric capacity
It is low level by the level conversion of the outfan of rectification filtering module 100 during C1 output current signal, thus
Illuminating lamp LP1 two ends are made to reach rated operational voltage and light.Whole lighting circuit has without artificial behaviour
Make, the advantage of saves energy.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all at this
Any amendment, equivalent and the improvement etc. made within bright spirit and principle, should be included in the present invention
Protection domain within.
