LED的发展与应用中英文翻译

LEDLED点阵模块或像素单元组成的显示屏幕。— LEDLED〔LightEmittingDiode〕，发光二极管，是一种固态的半导体器件，— LEDLED〔LightEmittingDiode〕，发光二极管，是一种固态的半导体器件，N们之间就形成一个“P-NPPLEDP-N的。二 LED进呈现状19901995要是单色和16级双色图文屏。用于显示文字和简洁图片，主要用在车站、金融证券、银行、邮局等公共场所，作为公共信息显示工具。LEDLED出来并得以应用。LEDLED1三 LED优点导体发光二极管(LED)作为第三代半导体照明光源。这种产品具有很多梦幻三 LED优点导体发光二极管(LED)作为第三代半导体照明光源。这种产品具有很多梦幻80%-90%而光效差不多的白炽灯可见光效率仅为10%-20%。(2)光线质量高：由于光谱中没有紫外线和红外线，故没有热量，没有辐射，属于典型的绿色照明光源。(3)0.05-1w，通过集群方式可以量体裁衣地满足不同的需要，铺张很少。以其作为光源，在同样亮度下耗电量仅为一般白炽灯的1/8-10。70%10下可以使用50年，即使长命百岁的人，一生最多也就用2只灯。(5)牢靠耐用：(6)应用敏捷：体积小，可以平面封装，易开发成轻薄短小的产品，做成点、线、面各种形式的具体应用产品。(7)安全：单位工作电压大致在1.5-5v之间，工作电20-70mA(8)绿色环保：废弃物可回收，没有污染，不像荧光灯一样含有汞成分。(9)响应时间短：适应频繁开关以及高频运作的场合近几年来我国LEDLEDLED掌握技术根本上是通信掌握方式，客观上影响了显示效果。所以导致早期的LED显示屏在国内很少，产品以红、绿双基色为主，掌握方式为通信掌握，灰度等级LEDLEDLED显示屏进入市场;电子计算机及微电子领域的技术进展，在显示屏掌握技术领域消灭了LEDLED更为宽阔，下面我就来谈谈LED在酒店和休闲场中的应用。一、酒店LED显示屏的效益2LEDLED电子显示屏可接收来自计算VCD、摄像机等传输的信息，并实时播放二维或三维动画、文字资料。效益.1、社会效益B、宣传酒店的《效劳承诺》等内容，提高其知名度。D、便利顾客。2、经济效益365万元计的广告收入，为投资者带来滚滚财宝；厦门白鹭州广场上的大型全彩屏，500200万元的纯利润为投资者带来源源不断的经济利益。大的、长期的、良好的社会效益和经济效益，起到一箭双雕的效果。二、酒店LED显示屏的作用1、起到衬托气氛的作用大节日的庆祝词等。32、起到宣传、普及学问的作用A、通过LED电子显示屏可播放各种法律、法规、条例及各种常识等。BLED诺》等。3、起到公告板的作用个人的荣耀榜及先进事迹等。4、起到公益广告的作用①、通过显示屏幕可播放天气预报；②、当地的人文、历史、地理、气候概况、风俗人情；③、当地地图、旅游交通图及各旅游景点的分布图；④、《文明市民公约》、酒店的宣传口号及重要闻等。5、可制造良好的经济效益。及单位承办活动及做宣传广告，同时也有利于提升酒店的知名度,充分表达酒店的档次〕。次及创立文明窗口方面起到了良好的作用。三、LED1、显示屏亮度高可视距离远,五百米内都能清楚可见;2、显示屏显示内容简洁明白颜色明媚,不会带来条幅或其它显示设备的粗糙感及厚重感.3/紫外等光谱并不含汞有害物质的绿色照明光源.4、显示屏是一种高科技的产品.它的承受能很快的将贵公司与时代接轨.显示屏的系统的承受，将使贵公司的信息化登上更高的台阶。4色。总得看来，led5ThedevelopmentandapplicationofLEDAsthefurtherdevelopmentofdisplaydeviceandtechnology,screendisplaysystemhasbeenwidelyusedinnationaleconomy,LEDdisplayasacarrierfordisplayinginformationisoneofmajormedia.LEDdisplayiscomposedbyusingLEDlatticemoduleorpixelunit.First
