1. An LED light string control system, comprising:
an LED light string, comprising at least one LED module,
a voltage generation apparatus, coupled to the LED light string, and
a control module, coupled to the voltage generation apparatus, and configured to control the voltage generation apparatus to change a signal provided to the LED light string to a first voltage level according to a first logic of a light command, and to change the signal to a second voltage level according to a second logic of the light command,
wherein the light command is composed of the plurality of first logics and the plurality of second logics; the control module controls the voltage generation apparatus to change the signal to the second voltage level as a distinction voltage level to distinguish the two consecutive first voltage levels once the first logics of the light command appear consecutively, and/or the control module controls the voltage generation apparatus to change the signal to the first voltage level as the distinction voltage level to distinguish the two consecutive second voltage levels once the second logics of the light command appear consecutively; the at least one LED module correspondingly generates a drive command according to the plurality of first voltage levels and the plurality of second voltage levels except the distinction voltage level so as to generate lighting behavior according to the drive command,
wherein the distinction voltage has a first time width, the first voltage level has a second time width, and the second voltage level has a third time width; the first time width is different from the second time width and the third time width.
