沈阳理工大学学士学位论文摘要发光二极管(LightEmittingDiode，LED)发明于20世纪60年代，它是利用半导体材料中的电子和空穴相互结合并释放出能量，使得能量带(EnergyGat，)位阶改变，以发光显示其所释放出的能量。LED具有体积小、寿命长、驱动电压低、耗电量低、反应速率快、耐震性佳等优点。随着社会的快速发展，LED照明装饰技术将在社会的应用越来越广。19世纪兴起的数字电路以其先天的便捷、稳定的优点在现代电子技术电路中占有越来越重要的地位。随着人们生活环境的不断改善和美化，在许多场合可以看到彩灯。LED彩灯由于其丰富的灯光色彩，低廉的造价以及控制简单等特点而得到了广泛的应用，用彩灯来装饰街道和城市建筑物已经成为一种时尚。但目前市场上各式样的LED彩灯控制器大多数用全硬件电路实现，电路结构复杂、功能单一，这样一旦制作成品只能按照固定的模式闪亮，不能根据不同场合、不同时间段的需要来调节亮灯时间和变化。关键词：LED；单片机；艺术彩灯I沈阳理工大学学士学位论文AbstractLightEmittingDiodewasinventedinthe1960s,Itistheuseofsemiconductormaterialintheelectronicandcavitiesmutualcombinationandreleaseenergy,andmaketheEnergyGatchangeandasemittingshowsreleaseenergy.LEDhassmallshape,longlife,lowvoltagedriver,lowpowerconsumption,reactionvelocityandSeismicsexgood,etc.Withtherapiddevelopmentofsociety,LEDlightingdecorationtechnologywillbeinsocialusedmoreandmorewidely.Theriseofdigitalcircuitinthe19thcenturywithitsinnateconvenientstableadvantagesinthemodernelectronictechnologyinthecircuitplaysmoreandmoreimportantposition.Aspeoplelifeenvironmentconstantlyimproveandbeautification,inmanyoccasionstoseecolorfullights.BecauseofitsrichLEDlights,lightcolor,lowcostandcontrolofsimplefeaturesandawiderangeofapplications.Withcoloredlightstodecoratethestreetsandcitybuildinghasbecomeafashion.ButonthemarketatpresentthestyleofLEDlightscontrollerwithallthehardwarecircuitimplementationmost,Circuitstructureiscomplexsinglefunction.Then,oncetheproductionoffinishedproductsaccordingtothefixedmodeonlyshine,cannotaccordingtodifferentsituationstheneedsofdifferentperiodtoadjustthelightontimeandchange.Keywords:LED;lightscontroller;semiconductormaterialII沈阳理工大学学士学位论文目录1引言.......................................................................................................................................11.1选题背景及目的.........................................................................................................................11.2LED介绍及其应用领域............................................................................................................11.3主要研究内容.............................................................................................................................31.3.1三基色的原理.......................................................................................................................31.3.2设计的主要内容...................................................................................................................32艺术彩灯系统......................................................................................................................52.1单片机的概念..................................................................................................................................52.2STC15F100系统单片机.................................................................................................................62.2.1引脚说明......................................................
