Abstract
A dimmable LED illumination system includes a LED lamp, a switch, and a driver. The LED lamp receives electric signals to emit light; the switch is connected to a power source, and generates a pulse signal by being turned off and then on again in a predetermined time; the driver connects the switch to the LED lamp to convert electric power of the power source into the electric signals which are supplied to the LED lamp when the switch is turned on. In addition, the driver saves a setting luminance, a default illumination mode, and a luminance adjustment mode. When the driver receives the pulse signal, one of the two modes is selected to light the LED lamp.
