Abstract

A driving device for an illuminating device may include a plurality of sub illuminating units. The driving device may include a plurality of sub driving modules in series connected to an input voltage source to distributively store energy from the input voltage source. Each of the sub driving modules is allocated with and electrically connected with one sub illuminating unit so as to release the stored energy to the sub illuminating unit allocated thereto.
