  LED, whose electroluminescent device is cold light illuminator with the specialities of energy saving, environmental protection, long operating life and small in size, is known as the 4th generation of illuminating source or of green lighting. This paper mainly describe designing indoor LED energy-saving table lamp with high lightness by means of intelligent control. The environmental signal inspected is changed into the signal that can be processed by A/D converter by means of sensor technology, sent into SCM to be computed, and then calculated and amplified to drive the driving circuit and display circuit of LED by A/D converter again. Moreover, this paper will introduce a set of Intelligent adjustable optical-intensity system of the light source of LED, provide the systematic hardware design, software flow chart and some data collected by pyroelectric infrared detector and photoconductive resistance. The advanced PWM dimmer technology employed, the PWM signal is generated after the procession of STC SCM. The LED light can automatically regulate the switch and brightness depending on the environmental brightness. This system owes the effects as follows, the improvement of power efficiency, energy saving and environmental protection.
