Claim 0:
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 a third voltage level as a distinction voltage level to distinguish between the two consecutive first voltage levels and/or the two consecutive second voltage levels once the first logics and/or 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.
