1. A light-emitting diode (LED) light set, comprising:
a controller, which comprises an electric plug adapted to connect to an external power supply to receive electrical power therefrom and a main control integrated circuit (IC) arranged in the controller and electrically connected to the electric plug; a main light string, which comprises main conducting wires electrically connected to the main control IC to receive the electrical power and a plurality of main light bulbs connected to the main conducting wires in a serial arrangement, each of the main light bulbs comprising an associate control IC arranged therein and electrically connected to the main conducting wires; and associate light strings, which are respectively and electrically connected to the associated control ICs arranged in the main light bulbs, each of the associate light strings comprising associate conducting wires electrically connected to the respective associate control IC and a plurality of associate light bulbs connected to the associate conducting wires; wherein the main control IC controls voltage and current and lighting mode applied to the main light bulbs of the main light string and each of the associate control ICs control voltage, current and lighting mode applied to the associate light bulbs of the associate light strings in such a way that the voltage and current supplied to the associate light strings are lower than the voltage and current supplied to the main light string so that the associate conducting wires are allowed to be thinner than the main conducting wires; and wherein the main conducting wires comprise at least one wire that transmits a control signal from the main control IC to the associate control IC and at least one wire that transmits electrical power from the main control IC to the associate control ICs and the main light bulbs. |
