System and method for controlling intelligent light

The invention provides a system for controlling intelligent light, comprising a light sensor which is used for detecting the brightness of an environment, a microprocessor and a displayer, wherein the brightness signal detected by the light sensor is switched into a voltage signal and then transmitted to the microprocessor, and the microprocessor adopts an AD converter thereof to switch the voltage signal into a digital signal and controls the brightness of the displayer according to the digital signal. Because the invention can automatically adjust the brightness of the displayers, the problem that the operation states of an air conditioner cannot be distinguished through the fixed brightness of the displayer in a high brightness environment, which is caused by the low brightness can be effectively solved, and the problem that the relaxation and the sleep of users are influenced by the high brightness in the low brightness environments, can be effectively solved.
