Abstract: An LED illumination system includes a control circuit having a timing unit, a control unit and a PWM signal generating unit. The timing unit divides an operating period of an LED lamp into a plurality of time segments, and outputs a clock signal at a start of each time segment to the control unit. 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 to the LED lamp. The constant current circuit outputs different electric currents to the LED lamp according to the PWM signals, to thereby control the LED lamp to emit light having different light intensities at the various time segments of the operating period.
