Abstract
A current balancing apparatus, a power supply apparatus, a lighting apparatus, and a current balancing method for preventing luminance imbalance are provided. The current balancing apparatus includes a balancer for balancing an AC current and a rectifier for generating a DC current by rectifying the balanced current. Hence, the luminance imbalance caused by dispersion of a light source can be addressed.
