5G167,2 pin, 7 pin are respectively the output of control signal, 5 pin are input, connect the audio frequency shaping amplification circuit, 4 pin ground connection, 6 pin open circuit, 3 pin connect the adjustable resistance and the electric capacity of VCO frequency in the decision 5G167 integrated package, the fixed juncture of sending and receiving light form selector switch also, another fixed juncture of luminous form selector switch connects the positive pole of electric capacity, also has certain contact open circuit, the other end of adjustable resistance, 8 pin of the movable contact of luminous form selector switch and 5G167 all connect the positive pole of D.C. regulated power supply, D.C. regulated power supply is given the power supply of audio frequency shaping amplification circuit by divider resistance, the audio frequency shaping amplification circuit is by the acoustic-electric converting unit, shaping amplifying unit and audio signal output unit are formed, the acoustic-electric converting unit is by pick-up and provide the divider resistance of pick-up operating voltage to form, connect by coupling capacitance and shaping amplifying unit, the shaping amplifying unit is selected integrated package LM386 for use, its output 5 pin connect by coupling capacitance and audio signal output unit, the audio signal output unit is base stage dividing potential drop drag flow biasing, the adjustable resistance that the exemplary power amplifier of collector electrode output, its basal low parry resistance are parallel with the output signal size of energy control power amplifiers is a music intensity adjustments potentiometer.The AC power output circuit is made up of three tunnel bidirectional triode thyristors that have light-emitting diode, the output that is connected to three control signals of control circuit respectively is 1 pin of 5G167,2 pin, 7 pin, light-emitting diode is serially connected in respectively between the control

can be regulated the audio signal of output, be admitted among the integrated package 5G176 of control circuit after amplifying rectification in order to change original VCO frequency of integrated package 5G176, its original pressure frequency of oscillation is by outward element adjustable resistance and electric capacity decision.Because control signal is a control AC power output circuit operating state, the frequency change of control signal, make the bidirectional triode thyristor operating state of AC power output circuit also change thereupon, the conducting state of AC load also changes thereupon like this, AC load of the present utility model is a color lamp, we saw like this is that the stroboscopic of color lamp is changing, because the output of integrated package 5G167 changes successively, therefore the luminous form control switch that inserts between its 3rd pin and the D.C. regulated power supply positive pole can change its output state artificially, promptly work as the 3rd pin and be connected on the D.C. regulated power supply positive pole, the whole output HIGH voltages of three road outputs of control circuit, the whole conductings of the bidirectional triode thyristor of AC power output circuit are all worked three tunnel AC load.When luminous form control switch makes the D.C. regulated power supply positive pole join with tripod by electric capacity again, three road outputs of control circuit are circulation output, promptly export high potential successively, make the bidirectional triode thyristor conducting in turn successively of AC power output circuit, output AC power.If luminous form control switch open circuit is promptly disconnected electric capacity to the D.C. regulated power supply positive pole, consequently control circuit has only a certain single channel output HIGH voltage.When the audio signal input is arranged, the flashing rate of its load is controlled by the adjustable resistance of control circuit and the power of input audio signal, during the input of absence of audio signal, three road cyclic flare frequencies are determined by adjustable resistance, the electric capacity of
