An intellectual control system includes a power supply input terminal, a primary controller, a controller signal terminal, a detector, a current output terminal and an LED module. The power supply input terminal, the primary controller the controller signal terminal and the detector are connected serially. The primary controller includes a function switch which is connected with the LED module through the current output terminal. The primary controller outputs a regulated low-voltage direct-current to the LED module. The LED module includes at least two LEDs having different color temperatures. The LED module has a whole color temperature that is regulated by changing an input current of the at least two LEDs of the LED module. The function switch of the primary controller adjusts a working state of the LED module. The detector includes a human body sensor and an optical sensor.
