With the development of science and technology, the requirement of intelligent control and energy save increases rapidly. From the above two points, a new design scheme of LED light brightness control is proposed in this paper. The brightness would be kept constant in the designated region. The constant brightness is realized by the illumination of the surrounding and LED light. The total circuit includes detection circuit and control circuit. The detection circuit is used to examine the outside brightness and transfer information to the control circuit. The control circuit determines the current of LED light.
