Abstract
The disclosure provides a lighting device and a voltage reduction method thereof, wherein the lighting device comprises: an AC power supply generator for generating an AC power source to supply power to other accessories and circuits in the lighting device; m load components, every two adjacent load components forming one head common connection point and one end common connection point respectively for each load component from head to end alternatively; and (m−1) current balancing cells each respectively connected between one head common connection point or one end common connection point and one of two output terminals of the AC power supply generator; wherein the m load components comprise (m−n) low impedance load components therein. The present application can reduce the output voltage of the AC power supply generator with lower cost.
