Be elaborated with regard to each circuit part of present embodiment below.
1, light-operated circuit 1
Base chip U1 when time base chip 11 be NE555, it and photo resistance RG1, RG2, variable resistor RP1 and R1 composition Schmidt trigger light-operated switch.The strong RG value of light on daytime is less, and after the RP1 dividing potential drop, U1 2～6 pin voltages are greater than 2/3VC, and VC is a supply voltage, and its output 3 pin low levels that are reset are to back grade U2, Q1 non-transformer are not worked.Thyristor switch breaks off, and electrodeless lamp WL does not work.To evening, the photo resistance resistance increases to more than the 1M Ω, after the RP1 dividing potential drop, makes U1 2,6 pin voltages less than 1/3VC, and then the Schmidt circuit of U1 formation is triggered, and 3 pin output becoming high level is to making subsequent conditioning circuit get into operating state.
For reliability and the job stability that improves light-operated circuit 1, two measures have been taked.The one, use two photo resistance and, influence performance to keep away from moisture with the sealing of transparent glass bottle; The 2nd, increase R1, C1 form anti-jamming circuit, in case receive night lightning, vehicle light to disturb the lamp operate as normal.
2, programmable timing electric circuit 2
Programmable timing electric circuit 2 comprises programmable Timer IC, variable resistor and small-sized toggle switch.To night RG be high resistance to making the time-base circuit U1 set that is triggered, 3 pin output high level is so programmable timing electric circuit CD4541 must establish the beginning timing by cable.This moment, 8 pin output initial states were low level because of 9 pin ground connection, the Q1 conducting, and photoelectrical coupler U3 work, it triggers thyristor Q2 conducting, and electrodeless like this lamp is connected civil power and is lighted.The time of lighting is regularly confirmed by U2.
CD4541 is a kind of programmable Timer IC, and the frequency of oscillation of its internal oscillator is confirmed that by the RP2 of external 1,2 pin and the numerical value of C4 the external R2 of 3 pin plays the frequency stabilization effect.
Timing t=2.3*N*RP2*C4 ... (1)
N is regularly a coefficient in the formula, and N numerical value is by programming end A, B, and promptly external high level of 12,13 pin or low level are confirmed.
N=27=128 when A=H, B=L; N=29=512 when A=L, B=H;
N=212=4096 when A=L, B=L; N=215=32768 when A=H, B=H.
So connect power supply or ground connection through small-sized toggle switch K1, K2, can select regularly coefficient N.Match with regulating RP2 in addition, can confirm required timing by (1) formula.
When timing arrives, U2 output 8 pin become high level by low transition, and then Q1 ends.U3 does not work yet, and Q2 turn-offs because of Triggerless, and electrodeless lamp extinguishes because of outage.
CD4541 is by the method that connects shown in Figure 1, and K1K2 closes and connect high level, and RP2 transfers when maximum, t=2.3*N*RP2*C4=2.3*32768*470*103*1*10
-6=35422.2 seconds=9.8395 hours, promptly maximum can be regularly about about 10 hours.

No-voltage triggers thyristor switch circuit 3 and comprises that thyristor Q2, triode Q1, zero-based trigger optocoupler U3 and R3～R5.Zero type triggers optocoupler U3 and has the function that triggers at the electric main zero crossing, therefore, passes through complete ac power waveform when making the thyristor conducting, so can not produce Harmonic Interference.This point improves than triggering with transistor or other photoelectrical coupler has tangible benefit, and compliance with environmental protection requirements.
In addition, thyristor Q2 two ends and on the RV piezo-resistance, make overvoltage protection usefulness, prevent that the overvoltage that produces at electrodeless lamp shutdown moment from damaging thyristor, improved product reliability.
4, power supply circuits 4
Civil power is through C6 step-down current limliting, and D1, D2 rectifying and voltage-stabilizing obtain the 12V DC power supply and supply entire controller to use after the C5 filtering.
