Abstract
A light emitting diode driving system is applied to a light emitting diode lamp string, such that the light signal is carried through a power line to reduce the signal transmission lines. The light emitting diode driving system includes a switch unit, a control unit and a light signal generating unit. The switch unit includes a power input side, a power output side and a controlled side. The power output side is electrically connected to the light emitting diode lamp string. The control unit is electrically connected to the switch unit. The light signal generating unit is electrically connected to the control unit and the power output side. The light signal generating unit generates a light signal when the control unit turns off the switch unit. The light signal generating unit sends the light signal to the light emitting diode lamp string.
