Classification: CPC H | IPC H

Claim 9:
10. A method of controlling an LED light string control system, the method comprising steps of:
changing a signal received by an LED light string to a first voltage level according to a first logic of a light command,
changing the signal to a second voltage level according to a second logic of the light command,
changing the signal to a third voltage level as a distinction voltage level for distinguishing between the two consecutive first voltage levels and/or the two consecutive second voltage levels when first logics and/or second logics of the light command appear consecutively, and
correspondingly generating a drive command, by at least one LED module of the LED light string, 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 light command is composed of the plurality of first logics and the plurality of second logics.
