The disclosure provides a driving apparatus and a method for driving a semiconductor light-emitting device assembly. The apparatus includes: a driving unit configured to drive the semiconductor light-emitting device assembly; and a cycle by cycle control unit. The cycle by cycle control unit may include: a sampling circuit configured to sample a current instantaneous value of the driving unit or the semiconductor light-emitting device assembly; and an adjusting circuit configured to adjust an output of the driving unit when the current instantaneous value sampled by the sampling circuit is larger than or equal to a preset reference value. The driving apparatus and method for driving the semiconductor light-emitting device assembly may effectively reduce an inrush current on the light-emitting devices and have a lower cost.
