隨著信息技術的飛速發展和社會的不斷進步，人們都市生活的迅速發展，新型半導體材料LED照明應用得到普及，人們對 LED 照明的高效控制和功能多樣化的要求也不斷提高。燈飾除了有普遍的照明作用之外，還有廣泛的工業用途。針對普通的LED光源存在光譜不全這個問題，本文介紹了一套小型智能燈，它是基于光敏電阻的照明系統，主要的功能是用光照強度來調節LED燈的亮度，就是通過光敏電阻接收到的外界不同的照度來控制LED燈不同的亮度，也就是說，本設計通過環境光照度的強弱對LED燈進行控制，而且可以自動變換，使生活和工業生產更加現代化和節能環保。這個設計的核心在于單片機控制模塊，光敏電阻通過外界照度的不同產生不同大小的電信號，本設計先根據電信號的大小規定好對應的數字信號，這樣單片機就可以根據輸入的數值信號發出紅綠黃三路通路/截止的命令，達到辨色的目的，判斷光強度做好防護，并且可從液晶屏上讀出光照強度，調控LED光強,這樣的設備在溫棚、禽舍、曬相、電路板生產等方面都得到廣泛的應用。

LIGHTING CONTROL SYSTEM DESIGN BASED ON PHOTORESISTOR
ABSTRACT
With the rapid development of information technology and social progress as well as the rapid development of urban life, new applications of semiconductor materials are popular LED lighting products. Efficient LED lighting and functional diversification of the requirements is also rising. Lighting not only have lighting effect, but also have extensive function of industry. This paper introduces a set of small smart lights, the lighting system which is based on photosensitive resistance, to solve LED light source for general spectrum insufficiency problem. Its main function is to automatically select the light color. Photoresistor receives different illumination of the light outside to control the three RGY-LED work or not. In other words, a lamp can automatically transform several colors light. It will save the energy sources make our life more modern . The SCM ( Single Chip Micyoco) module is the core of this design. Photoresistor generated different signals by different external illumination. The design first turn analog signals into digital signals.Accroding the digital signals, SCM will release the orders to control RGY-LED work or not.In this way, the purpose is able to choose colors of the light intellectuality.At the same time it can read the light intensity On the LCD panel to regulat the intensity of Lighting system . Such equipment Have extensive application on Greenhouse, birdhouse, bask in phase, circuit board production.朗讀
