Abstract
A rectifier rectifies an alternating current power to obtain a direct current power. The rectifier sends the direct current power to a driving power and synchronous signal generation apparatus. The driving power and synchronous signal generation apparatus generates a driving power. The driving power and synchronous signal generation apparatus sends the driving power through a transmission line to a plurality of light emitting diode driving apparatuses to drive a plurality of light emitting diodes. The driving power and synchronous signal generation apparatus generates a synchronous signal regularly according to the direct current power. The driving power and synchronous signal generation apparatus sends the synchronous signal through the transmission line to the light emitting diode driving apparatuses. The light emitting diode driving apparatuses drive the light emitting diodes synchronously according to the synchronous signals.
