【正文】 摘 要 在生活當中，照明在能耗當中所占的比例越來越大，當今照明的節(jié)能越顯重要。一個好的照明控制系統(tǒng)，能為人們的生活、學習、工作等提供良好的視覺條件，營造舒適的光環(huán)境。目前在國內(nèi)和國外通常使用的大概有這幾種類型：觸摸型、聲控型、感光型等。 論文主要介紹了基于單片機的家庭智能 LED 照明燈具的設計。設計采用單片機作為控制系統(tǒng)，結合 LED 照明技術、光感技術、紅外傳感技術等實現(xiàn)了對照明設備的智能化控制。智能化照明設備克服了傳統(tǒng)照明設備耗能、不便于調(diào)節(jié)光強等缺點，實現(xiàn)了對光強調(diào)整的人性化、智能化的控制。 硬件設計主要包括單片機控制電路、按鍵電路、 LCD 顯示電路 、 熱釋電傳感器處理電路 。軟件設計主要包括單片機主控程序、 ADC 控制程序的設計和 LCD 顯示程序的設計 。家庭智能 LED 照明燈具通過人體感應模塊（熱釋電傳感器）決定 LED 燈的關閉和開啟。同時可以通過光照檢測電路對周圍環(huán)境亮度進行檢測，進而實現(xiàn)對 LED燈的控制。設計通過點亮 LED 燈的個數(shù)來實現(xiàn)光照強度的調(diào)整，同時可用按鍵熄滅或者開啟一組 LED 燈。解決了照明設備關閉、自適應調(diào)整和自動開啟的問題，從而達到良好的光環(huán)境和調(diào)光效果。 關鍵詞： 單片機；光敏傳感器；節(jié)能 ； LED 燈；智能控制 ABSTRACT In life, lighting in the proportion of energy consumption which is more and more big, the energy saving of today39。s lighting is more important. A good lighting control system, for people39。s life, study, work, etc. to provide a good visual conditions, and create a fortable light environment. It is usually used at home and abroad about several types: touch type, sound type, photosensitive type etc.. This paper mainly introduces the design of intelligent LED lighting lamps based on single chip microputer. Design uses a microcontroller as control system, bined with the LED lighting technology, optical sensing technology, infrared sensing technology to realize the intelligent control of lighting equipment. Intelligent lighting equipment to overe the traditional lighting equipment, energy consumption, is not easy to adjust the light intensity and other shortings, to achieve the light intensity adjustment of human nature, intelligent control. The hardware design mainly includes the single chip microputer control circuit, the key circuit, the LCD display circuit, the pyroelectric sensor processing circuit. The software design mainly includes the control program of the single chip microputer, the design of the ADC control program and the design of the LCD display program. Home intelligent LED lighting lamps through the human body induction module (pyroelectric sensor) to determine the LED lights off and open. At the same time, the brightness of the surrounding environment can be detected by the light detection circuit, and then the control of the LED lamp can be realized. The design of a number of the LED lamp lit to achieve light intensity adjustment, while keys can open out or a group of LED lamps. To solve the problem of lighting equipment closed, adaptive adjustment and automatic opening, so as to achieve a good light environment and light adjustment effect.
