Abstract
An illumination system includes an LED lamp, a timer, a controlling circuit, a driving circuit and a power source electrically connected together. The timer produces different signals to the controlling circuit at different periods, thereby driving the LED lamp to lighten with different brightness. A light or movement sensor is further electrically connected to the LED lamp to work together with the timer. The sensor cooperating with the timer, detects light or movement of an object to drive the LED lamp to lighten for a while with a corresponding brightness.
