Abstract: A point-controlled LED light string and a manufacturing method thereof, the light string comprises a DC power supply controller integrated with a plurality of address registers; and LED lights each with a unique address code. The LED lights form a light string with an address code random method, according to a sequence in which the LED lights are connected and arranged in the light string, associating the LED lights one to one with the corresponding address registers, and each of the address registers stores a corresponding address code of a corresponding LED light. The method comprises the steps of selecting LED lights each with a unique address code by an address code random method randomly to form a light string, storing the address codes of the LED lights in address registers arranged in an orderly manner, and associating the address registers one to one with corresponding LED lights.
