Abstract
A light emitting diode system includes a light emitting diode lamp string, a signal voltage unit and a control unit. The light emitting diode lamp string includes a plurality of light emitting diode units. The control unit drives the signal voltage unit to adjust a voltage of the light emitting diode lamp string continuously and repeatedly so the voltage of the light emitting diode lamp string is a predetermined voltage, to form a light signal comprising a plurality of pulse waves to send the light signal to the light emitting diode lamp string. When each of the light emitting diode units receives the light signal, each of the light emitting diode units performs a conversion and a decoding for the light signal to obtain a lighting mode of the light signal, and then each of the light emitting diode units lights based on the lighting mode.
