Abstract:
1. A structure of a color mixture synchronization circuit of an LED light string, characterized in that each of LED lights of an LED light string comprises two input pins and two output pins, wherein the two input pins are respectively an input pin of two light emitting chips of four primary color light emitting chips of R, G, B, and Y that are connected in parallel and opposite in direction and an input pin of the remaining two light emitting chips that are connected in parallel and opposite in direction; and the two output pins are respectively an output pin of the two light emitting chips of the four primary color light emitting chips of R, G, B, and Y that correspond to one of the input pins and are connected in parallel and opposite in direction and an output pin of the remaining two light emitting chips that correspond to another one of the input pins and are connected in parallel and opposite in direction, whereby each of the LED lights of the LED light string is connected in series, in a two-input-two-output arrangement with two terminals in combination with four wires, to form a light string.
