LED简介LED目录LED概述LED(Light Emitting Diode),发光二极管,是一种固态的半导体器件,它可以直接把电转化为光。
LED的心脏是一个半导体的晶片,晶片的一端附在一个支架上,一端是负极,另一端连接电源的正极,使整个晶片被环氧树脂封装起来。
半导体晶片由两部分组成,一部分是P型半导体,在它里面空穴占主导地位,另一端是N型半导体,在这边主要是电子。
但这两种半导体连接起来的时候,它们之间就形成一个“P-N结”。
当电流通过导线作用于这个晶片的时候,电子就会被推向P区,在P区里电子跟空穴复合,然后就会以光子的形式发出能量,这就是LED发光的原理。
而光的波长也就是光的颜色,是由形成P-N结的材料决定的。
LED历史50年前人们已经了解半导体材料可产生光线的基本知识,第一个商用二极管产生于1960年。
LED是英文light emitting diode(发光二极管)的缩写,它的基本结构是一块电致发光的半导体材料,置于一个有引线的架子上,然后四周用环氧树脂密封,即固体封装,所以能起到保护内部芯线的作用,所以LED的抗震性能好。
发光二极管的核心部分是由P型半导体和N型半导体组成的晶片,在P型半导体和N型半导体之间有一个过渡层,称为P-N结。
在某些半导体材料的PN结中,注入的少数载流子与多数载流子复合时会把多余的能量以光的形式释放出来,从而把电能直接转换为光能。
PN结施加反向电压时,少数载流子难以注入,故不发光。
这种利用注入式电致发光原理制作的二极管叫发光二极管,通称LED。
当它处于正向工作状态时(即两端加上正向电压),电流从LED阳极流向阴极时,半导体晶体就发出从紫外到红外不同颜色的光线,光的强弱与电流有关。
最初LED用作仪器仪表的指示光源,后来各种光色的LED在交通信号灯和大面积显示屏中得到了广泛应用,产生了很好的经济效益和社会效益。
以12英寸的红色交通信号灯为例,在美国本来是采用长寿命、低光效的140瓦白炽灯作为光源,它产生2000流明的白光。
