Abstract
The present invention provides an LED current balance apparatus, which utilities capacitances coupled to secondary windings of a transformer to store voltage differences between LED strings. Thereby, the driving voltages applied to LED strings are respectively modulated to make the LED strings flowing through a same driving current. A current regulating apparatus is coupled to all LED strings to stabilize total current of the LED strings at a predetermined current.
