Claim 6:
7. The LED light string control system as claimed in claim 2,
wherein the at least one LED module comprises:
a first capacitor, coupled to the at least one LED module in parallel, and configured to provide a first energy storage voltage to regulate the at least one LED module,
wherein the third voltage generation circuit comprises:
a fourth switch, coupled to the LED light string and a ground point, and a voltage of the ground point to be the third voltage, and
a fifth switch, coupled to the LED light string in parallel,
wherein the control module turns on the fourth switch and the fifth switch according to a distinction logic so as to change the signal to the third voltage as the distinction voltage level.
