In this thesis, for adjustable color temperature of lighting equipment, both a drive and control circuit architecture. The architecture is composed by the flyback PFC converter, PWM control circuit and LED color temperature module, to improve the power factor and efficiency. LED is a current control element. In this thesis used the boost converter module drive circuit as LED color temperature, current mode control to provide the desired stable current source; and the microcontroller output PWM signal to control the drive circuit, thereby changing the average forward current through the LED, to change the color temperature function.
