					Super dancing AC lights 4500 watt
using opto isolator
I am extremely proud to present to you this circuit. We dare to challenge that.
When you have contact with the circuit. You may have forgotten to do another
circuits.
In addition to the ability to work resolutely. The circuits is designed. With
safety as a priority. So we use optocoupler isolator to isolate the AC line power
circuit and the control system circuit is strictly prohibited.
In addition will is protection from electric shock to the user. One thing is
important. The protection of the AC line power is not doing any harm to your
machine.
And sitting circuit to an input circuit has a value up to 50K OHM. So make sure
that your audio device of any size Both a high power or a low watt amplifier
will not be certainly loaded until failure.
In Figure 1 is shown block diagram of the super dancing lights of 4,500 watt
will see that the input signal is entered through the filter circuit. Which the
filter to each series will qualify with frequency as follows.
The low pass filter will allows the frequency under 200HZ only.
The band pass filter will allows the frequencies only over 2000HZ up.
The signal from the filter circuit will pass through a schmitt trigger circuit to
controls a light flashing as on-off, is rhythmic by the sound signal absolutely
different from other circuits that you use to see ago.
The output signal from the schmitt trigger circuit send to the OPTO ISOLATOR
circuit to drive the driver circuit and output.




How this circuit works.
The input signal of the speaker will be entered pass through a input resistor R1
come to a master control volume, that act as control a level of a input signal
that will enter to the filter circuit to has good enough level. Do not strong too
much, or a little.
The output signal from the master volume will apply from the potentiometer ,
that act adjust a level signal each channel to the filter circuit each set to has
level of signal Appropriately as needed.
The low range frequency signal will be fed through R1, C1 to the transistor
Q1(BC557) to pin 12 of IC1-(MN5693BN) , which act as the schmitt trigger
circuit has the output pass the R16 to IC2-(TLQ-074) the opto isolator, that has
output to drive the driver Q5(BC547) go to a triac Q8 makes the lamps lit up
as the strength of the signal at low frequencies.
For high frequency entering through C3, C4 to Q3. and the schmitt trigger
circuit pin 5 to the IC2 to drive the lamp at the Q7 circuit , In the same
manner. Frequency range can be entered through the band pass filter circuit
comprising R14, C5, C2 to base of Q2(BC557) and the schmitt trigger circuit at
pin 8 to drive the load driver Q9(BTA10-400V) as with other circuits.
As see that the power supply circuit is divided into two parts, one will be
supplied to the input control circuit.
And another pass to the driver circuit Q4(BC547)-Q6(BC547) makes the
control circuit isolated from the AC line power-220V is strictly prohibited. It is
to ensure 100% safety.
How to assemble circuit.
All equipment can be assembled onto the PCB, as shown in Figure 2.
All devices on assembly PCB correctly. Check the soldering tightly successfully.
Then, check this PCB, that there is short circuit or not, In particular, the point
at which the AC-Line power and The control circuit may cause life threatening.
When assembly experiment was to apply the power AC to the circuit. All bulbs
lamps will be be extinguished completely. Try connecting the input signal from
the amplifier speaker of any side of half time. Be careful not Provide short
circuit the input wire is determined by the output of power amplifier may be
damaged.
       Try refining. potentiometer on the lamp lit by the strength of the input
signal is fed into the desired range.
