Claim Text:
1. A dimmable LED illumination system, comprising: an LED lamp for receiving electric signals to emit light; a switch connected to a power source, wherein the switch generates a first pulse signal by being turned off and then turned on again within a first predetermined time; and a driver connecting the switch to the LED lamp to supply the electric signals from the switch to the LED lamp, wherein the driver has a controller, and the controller saves a luminance setting, a default illumination mode, and a luminance adjustment mode; wherein the default illumination mode is triggered when the switch is turned on, and in the default illumination mode the controller controls the LED lamp to light with the luminance setting; wherein the luminance adjustment mode is triggered when the controller receives the first pulse signal, and in the luminance adjustment mode the controller controls the LED lamp to automatically gradually cycle between a minimum brightness and a maximum brightness, and when the controller receives a second pulse signal from the switch by being turned off and then turned on within a second predetermined time during the luminance adjustment mode, the controller saves the current brightness of the LED lamp as the luminance setting.
