Abstract
A driving device for driving a plurality of lamp modules includes a plurality of power stage circuits, a plurality of driving circuits, a multi-phase controller and a controller. The power stage circuits, corresponding to the lamp modules, convert received direct current (DC) signals to alternating current (AC) signals to drive the lamp modules. The driving circuits are correspondingly connected to power stage circuits, for outputting driving signals to control outputs of the power stage circuits. The multi-phase controller is connected to the driving circuits, for controlling the driving circuits to output the driving signals in different periods. The controller is connected to the driving circuits, for controlling outputs of the driving circuits.
