摘要： An LED illumination system includes a control circuit having a timing unit, a control unit, a PWM signal generating unit and a micro-programmed control unit (MCU). The timing unit divides an operating period of an LED lamp into different time segments, and outputs clock signals. The control unit outputs different controlling signals corresponding to the clock signals to the PWM signal generating unit, which in turn generates different PWM signals with different duty cycles. A constant current circuit electrically connects the control circuit and outputs different electric currents to make the LED lamp emit light having different light intensities at the different time segments. The MCU is at an outside of the LED lamp and sets a program to control the timing unit, the control unit and the PWM signal generating unit.
