Abstract
The invention belongs to the technical field of lighting, and particularly relates to a lighting circuit and a lamp. A microphone, a signal amplification module, a photosensitive resistor, a trigger module, a capacitor C1 and a level control module are added to a lighting circuit provided with a lighting lamp, a rectifier and filter module and a voltage conversion module. The photosensitive resistor controls the signal amplification module to work or stop working according to the intensity of external light. The microphone converts a sound signal into an electrical signal, and the electrical signal is amplified by the signal amplification module. The trigger module outputs a trigger signal to the capacitor C1 when receiving the electrical signal. The capacitor C1 is used for outputting a current signal to the level control module when receiving the trigger signal, and performing charging at the end of discharging. The level control module reduces or maintains the level at the output end of the rectifier and filter module according to whether there is a current signal or not. Thus, the voltage at the two ends of the lighting lamp reaches the rated working voltage, and the lighting lamp is turned on. The whole lighting circuit has the advantages of no need for manual operation, and electrical energy saving.

When external environment condition illumination is strong by day, the resistance value of photo resistance RG is very little, and the current collection of triode Q2 is low level very, and triode Q2 is in cut-off state.Now the base stage of NPN type triode Q4 is high level, and NPN type triode Q4 is in saturation conduction state.Because the control end of thyristor Q1 is low level, thyristor Q1 is in cut-off state.Because the output voltage of rectification filtering module 100 is too high, illuminating lamp LP1 does not reach rated operational voltage, and whole circuit is not worked.
When night, external environment condition illumination died down, it is large that the resistance value of photo resistance RG becomes, and the collector electrode level of triode Q2 raises, and whole circuit is all in treating standby state.If now there is voice signal input microphone MK1, microphone MK1 outputs to the base stage of triode Q2 and amplifies processing by triode Q2 voice signal being converted to the signal of telecommunication, and the signal of telecommunication after amplification is through capacitor C 2 trigger switch pipe 100 conductings.Once switching tube 100 conductings, its input current potential becomes low level.Now electric current is flowed out by capacitor C 1 second end, and the first end that flows into capacitor C 1 through resistance R 2, resistance R 4 and voltage transformation module 200 forms loop.NPN type triode Q4 is because electric current flows out and reverse bias from base stage, and NPN type triode Q4 ends.Due to NPN type triode Q4 cut-off, the control end of thyristor Q1 becomes high level, thyristor Q1 conducting.Meanwhile, the output voltage of rectification filtering module 100 also becomes low level, and illuminating lamp LP1 is lit because reaching rated operational voltage.
