Subharmonic filter can effectively eliminate the low-order harmonic in electric current, keep output electric current more stable.To which the circuit can be effective
Improve the stability of present invention output electric current.
Meanwhile voltage signal is when being transferred to rejector circuit, the polar capacitor C11 of the circuit is by the height in voltage signal
Frequency interference voltage signal is decayed, electricity of the impedor that resistance R15 and resistance R16 and resistance R17 are formed to voltage signal
Magnetic wave interference voltage is eliminated, and keeps the level of voltage signal stronger, and diode D6 drives high level and is switched on, triode
Level on the collector of VT6 enhances conducting, and triode VT6 output voltage signal is given by amplifier P, inductance L, resistance R21, electricity
The signal intensifier circuit that R22 and diode D7 is formed is hindered, after the amplifier P of the signal intensifier circuit amplifies voltage signal
It is transferred to and puts after being eliminated by the degaussing circuit that inductance L and polar capacitor C13 is formed to the electromagnetic component in voltage signal
Big circuit effectively raises the present invention and controls the open and close of illumination DHL to improve the accuracy of voltage signal
Effect.
When there is light to be irradiated on photo resistance RG, the resistance value of photo resistance RG can reduce, in the base stage of triode VT2
Voltage can then be pulled low and by voltage in the base stage of triode VT3 rises, and is clipped to triode VT4 also, at this time
Photosensitive control circuit is off state, and electric current is not transmitted, i.e., after circuit no power, headlamp HL are not lit afterwards；When
When dull thread is irradiated on photo resistance RG, the resistance value of photo resistance RG can become larger, and the voltage at the both ends polar capacitor C4 increases, pole
Property capacitor C4 saturation after discharge triode VT2, the voltage in the base stage of triode VT2 then will increase and be switched on, triode
Voltage in the base stage of VT3 reduces, and is switched on triode VT4, and photosensitive control circuit at this time is on state.Make electricity in this way
Stream signal can be transferred to triode VT5 by triode VT4 and carry out secondary amplification, and amplified current signal is transferred to two
The control terminal that the electric current is transferred to unidirectional thyristor VS after adjustable resistance R13 is connected in pole pipe D5, diode D5, brilliant after triggering
Brake tube conducting, relay K obtain electric, and the normally opened contact K-1 of relay K closure, the road where headlamp HL, which just constitutes, to be closed back
Road, headlamp HL obtain electric, are lit.When being lit if necessary to headlamp when ambient brightness is bright enough, then it can will open
S closure is closed, which can then be in long-term on state.
The present invention not only realizes the open and close of sound and photocontrol headlamp HL, while can also be adjustable by adjusting
The resistance value size of resistance R13, to realize the adjusting to size of current, to adjust the Trigger Angle of unidirectional thyristor VS to control photograph
The voltage value size of the voltage input end of bright lamp HL, so that the brightness for being able to achieve control bright lamp HL is controlled.That is adjustable resistance
The resistance value of R13 tunes up, and electric current becomes smaller, and the Trigger Angle of unidirectional thyristor VS becomes larger, and the angle of flow becomes smaller, so that voltage effective value subtracts
Small, headlamp HL is dimmed.Conversely, the resistance value of adjustable resistance R13 is turned down, electric current becomes larger, and the Trigger Angle of unidirectional thyristor VS becomes smaller,
The angle of flow becomes larger, so that voltage effective value increases, therefore headlamp HL brightens.To which the present invention can effectively be improved to headlamp
The control effect of HL can effectively solve that headlamp is opened by mistake the problem of opening, and greatly save electric power resource.
Headlamp HL in the present invention preferentially selects osram lamp, and main cause is that sonic-opticalcon trolled switch is opened by electronic loop
Dynamic, the lamp starting current with rectifier is larger, be easy to cause the breakdown of electronic component, damages circuit.Sonic-opticalcon trolled switch starting frequency
Numerous service life that can shorten lamp to a certain extent for energy conservation waits.Halogen lamp can not be reached before closing simultaneously
Brightness.So general lamps and lanterns are not suitable for use in sonic-opticalcon trolled switch circuit.
According to above-described embodiment, the present invention can be realized well.
