Various embodiments relate to a load driver and a luminaire including the load driver. The load driver may include a voltage limiting circuit including a first polar capacitor and a second polar capacitor connected in inverse series, which are connected in parallel respectively with first and second current limiting elements, where the first and second current limiting elements limit the direction in which current flows so that current flows through different polar capacitors in positive and negative halves of a cycle of an alternating-current power supply.

Load driver and luminaire including the load driver

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.
