Led decorative light with code writing triggered by an external signal

Abstract

A light-emitting diode (LED) decorative light with code writing triggered by an external signal, includes: a controller and a light string. A positive terminal and a negative terminal of the controller are connected to the light string. The controller supplies power to the light string through the positive terminal and the negative terminal, and loads a control signal on the positive terminal or/and the negative terminal. The light string includes a plurality of code-writable LED modules. After receiving an external signal, the code-writable LED modules complete code writing according to the control signal. Highly efficient code writing for LED modules through external signal triggering can be achieved, thereby avoiding address code writing errors caused by writing addresses during the assembly of LED modules into the light string, and preventing the instability and unreliability of determining LED module address codes based on their positions in the LED light string.
