ABSTRACT:
A digital controlled multi-light driving apparatus for driving and controlling a plurality of lights. The digital controlled multi-light driving apparatus includes a plurality of oscillation step-up circuits and a digital control circuit. The digital control circuit has a counter unit, a memory unit, a comparator unit, and a driving unit. The counter unit starts counting to generate a counting value whenever a digital start signal is generated. The memory unit stores at least one target counting value. The comparator unit is electrically connected to the counter unit and the memory unit to generate triggering signals whenever the counting value matches the target counting value. The driving unit is electrically connected to the comparator unit to output sequentially delayed driving signals to the oscillation step-up circuits respectively on receiving the triggering signals.
