Claim 1:
2. The LED light string control system as claimed in claim 1, wherein the voltage generation apparatus comprises:
a first voltage generation circuit, coupled to the LED light string and the control module,
a second voltage generation circuit, coupled to the LED light string and the control module, and
a third voltage generation circuit, coupled to the LED light string and the control module,
wherein the control module controls the first voltage generation circuit to generate a first voltage to change the signal to the first voltage level; the control module controls the second voltage generation circuit to generate a second voltage to change the signal to the second voltage level; the control module controls the third voltage generation circuit to generate a third voltage to change the signal to the distinction voltage level.
