  • LED LIGHTING SYSTEM AND POWER SYSTEM THEREOF
    Publication number: 20110121740
    Abstract: An LED lighting system including an LED device, a current-balancing device, a comparing device, a power device, and a control device is provided. The current-balancing device generates a feedback voltage based on the operation condition of the LED device. The comparing device compares the feedback voltage with a reference voltage and accordingly generates a compared result. The power device is used for providing a DC voltage to the LED device. The control device generates a control signal based on the compared result. The power device adjusts the DC voltage according to the control signal.
