But people often forget to turn off the lights and caused great waste of energy. Its very inconvenient to turn on the lights in the dark. Now most of the desk lamp is using filament lamp, fluorescent lamp and energy-saving lamps.And the control mode is often used manual switch.Those desk lamp cant continuous adjustment and cant automatic adjustment,too.This project design a kind of intelligence desk lamp by using heat-releasing infrared sensor and BISS0001.This desk lamp have intelligent switch and it can automatically adjustable light.You neednt control this desk lamp by your hands. This reflects the modern home appliance intelligent and human nature in the design idea. At the same time the desk lamp also have the function of protect eyesight . When the user stand too close to the desk lamp,it will warn people to leave the desk lamp by rang the alarm.KEYWORDS: smart switch, auto-control, protect eyesight, biss0001目錄摘要IABSTRACTII1緒論11.1方案的提出11.2方案介紹21.2.1方案選擇21.2.2 功能與指標(biāo)31.2.3方案簡(jiǎn)述32部分元件介紹52.1 7812/7805穩(wěn)壓器52.1.1 LM78系列穩(wěn)壓器結(jié)構(gòu)圖52.1.2 LM78系列穩(wěn)壓器介紹52.2熱釋電紅外傳感器72.2.1熱釋電傳感器結(jié)構(gòu)72.2.2熱釋電傳感器簡(jiǎn)介72.2.3熱釋電傳感器RE200B的參數(shù)92.3 BISS0001集成芯片102.3.1 BISS0001結(jié)構(gòu)圖102.3.2 BISS0001敘述112.3.3 BISS0001管腳說明122.3.4 BISS0001工作原理132.4光電耦合器152.4.1光電耦合器原理圖152.4.2光電耦合器常用參數(shù)152.4.3光電耦合器選取規(guī)則162.4.4光電耦合器應(yīng)用于開關(guān)電路中的工作原理172.4.5使用光電耦合器的注意事項(xiàng)192.5三極管恒流源192.5.1三極管的恒流特性192.5.2三極管射極偏壓設(shè)計(jì)范例203硬件組成223.1電源模塊223.1.1電源模塊電路圖223.1.2電源模塊電路分析223.2感應(yīng)信號(hào)處理模塊243.2.1感應(yīng)信號(hào)處理模塊電路圖243.2.2 熱釋電紅外傳感器電路分析253.2.3 信號(hào)放大電路電路分析263.2.4 延時(shí)電路電路分析283.2.5 其他組成部分電路分析293燈光處理模塊31
