Abstract In order to make use of electricity efficiently, this design of intelligent LED lamp which is based on STC89C51RC single-chip microcomputer is proposed in this paper. The lamp has two types of regula- tion, manual regulation and automatic regulation. The hardware design part consists of SCM control module, keyboard module, lighting module, photosensitive module, LED module and so on. SCM mas- ter control chip chooses STC89C51RC. Through the key module, SCM adjusts the working mode and the LED brightness. Lighting module uses white LED in the type of 12 straw hats. Photosensitive module uses ADC0832 chip to implement the light signal acquisition, and uses PWM dimming technology to automatically adjust the luminosity of LED. Through programming SCM C language, the software is de- signed and the procedure is loaded into SCM.
