Abstract
A light emitting diode lamp string driving system includes a plurality of light emitting diode driving apparatuses and a plurality of light emitting diode lamp strings. The light emitting diode lamp string includes a plurality of light emitting diodes. The light emitting diode driving apparatus includes a switch unit, a control unit and a voltage level generating unit. An anode of a last of the light emitting diodes of the light emitting diode lamp string connected to a first of the light emitting diode driving apparatuses is connected to the control unit of a second of the light emitting diode driving apparatuses.
