Abstract
A light emitting diode lamp string system with a sequencing function includes a light emitting diode driving apparatus and a light emitting diode lamp string. In a predetermined sequence testing mode, the light emitting diode driving apparatus sequentially sends a plurality of predetermined sequence testing signals to the light emitting diode lamp string to find out the damaged light emitting diode lamp. In an extended sequence testing mode, the light emitting diode driving apparatus respectively sends a plurality of extended sequence testing signals to the light emitting diode lamp string to find out the new light emitting diode lamp. A sequencing method performs a predetermined sequence testing mode to detect a failure address code, and performs an extended sequence testing mode to detect a replacement address code, and replaces the failure address code with the replacement address code in a testing sequence.
