This festival lantern works control circuit shown in Figure 1. The circuit uses four CMOS digital integrated circuit chips and 8 opto triac chip, which is a decimal count of IC1 / distributor, IC2 is six Schmitt trigger (F1 ~ F6); IC3, and IC4 are Second, input four "and" gate (Y1 ~ Y8). From the F1, RP1, C1 to form a super-low-frequency oscillator with adjustable frequency, the output signal as the count clock IC1. RP1 oscillator oscillation frequency can be adjusted. F3 ~ F6 of the inputs and outputs, respectively, in parallel, the drive circuit used LED1. LED1 for ultra-low-frequency oscillator output instructions. In IC1's output of Q1 ~ Q8, respectively, by the isolation diode VD1 ~ VD8 connected to the Y1 ~ Y8 of the b input, while the Q0 output of IC1 is connected to the input of F2, F2 is connected to the output of Y1 ~ Y8 of a input, so that the output can be from the F2 potential control Y1 ~ Y8 timely "reset." Y1 ~ Y8, respectively, after the output current limiting resistor connected to the corresponding GK1 ~ GK8 of feet (light-emitting diode inside the cathode) on, GK1 ~ GK8 of feet (internal light-emitting diode cathode) are connected to the power supply negative terminal. This will by the Y1 ~ Y8, respectively, control the output of the corresponding potential GK1 ~ GK8 conduction or cut-off, GK1 ~ GK8 the direct control of the 8 string bulbs strung with hundreds of small lanterns (H1 ~ H8) composed of "celebrate the fiftieth anniversary of the founding of" light off the text. In each "and" gate output through a resistor, respectively, also connected to this "and" gate input b, so that makes Y1 ~ Y8 "and" doors can become a trigger to be locked in by the the output is high potential triggers. Circuit power of the moment, the role of the C2 and R2, IC1 is automatically reset, the Q1 ~ Q8 outputs are low voltage, Q0 output is high potential, the potential of F2 is lower after RP increase in Y1 ~ Y8's a input, so that Y1 ~ Y8 output are low, so this time GK1 ~ GK8 not work, H1 ~ H8 string lights are off. When the F1 component of the ultra-low-frequency oscillator output of the first arrival of a count pulse, IC1's output goes low potential Q0, the inverted F2 added into the high potential of a Y1 ~ Y8 input for the Y1 ~ Y8 high potential to prepare the controlled output. At this time of the Q1 output of IC1 goes high potential to meet the Y1 "and" conditions, the output becomes high-potential, driven by R20 GK1 in the light-emitting diode, to conduction within the SCR by the H1 series lamp composed of "celebrate" the word light. At the same time, Y1 output of high potential but also by the R12 feedback to the b input, so that Y1 into the "captive" state. When F1 first two counts the output pulse arrives, IC1's Q1 output to low potential, the Y1 is the "Self", it is still in GK1 SCR in conduction state, H1 is still lit. At this point the Q2 output of IC1 goes high potential, so that Y2 to meet "and" conditions, the output of high potential and after R13 "captive" while driving GK2 through R21 in the light-emitting diode and to SCR conduction, H2 formed by the string of lights to make a "wish" the word light ... .... As noted above, when the F1 output of the first eight count pulse arrives, IC1's output goes high potential of Q8, the Y8 to meet "and" conditions, the output of high potential and after R19 "captive" while driving through the R27 GK8 make light-emitting diode in the SCR turns on, the string of lights formed by the H8 "year" the word light. At this point, "to celebrate the fiftieth anniversary of the founding of" light string of 8 characters have all been lit, were lit by a lamp circuit to complete the 8 string composed of the text function. When F1 first nine counting the output pulse arrives, IC1's output Q9 goes high potential, but does not use the floating output, so the circuit does not occur any change at this time, 8 string lights remain lit while the state unchanged. When the F1 section 10 counts the output pulse arrives, IC1's output Q0 goes high potential, the potential of F2 is lower after RP increase to Y1 ~ Y8 of a input, so that Y1 ~ Y8 also "reset", the have become a low potential output, leading to GK1 ~ GK8 also result in the same cut-off thyristor, so that H1 ~ H8 string lights all went out, now, to complete a cycle, the cycle of the circuit. F1 output pulse when the count comes again, the circuit will depend on the above principle has been to start a new cycle will do the same cycle continues ... .... The cycle of light speed of light strings can be changed by adjusting the RP1.
