R课堂 | LED元器件发光原理科普
本文的关键要点
当电流流过半导体晶片时,p型半导体的空穴和n型半导体的电子复合,使LED发光。
LED的发光波长会因发光元件的材料及其比例而异。

LED为什么会发光?
LED的发光原理
LED为什么会发光?
在我们的生活中,LED的使用非常广泛(比如显示器和照明等),那么,它们究竟是如何发光的呢?
例如,灯泡和荧光灯是通过灯丝发热和放电现象等间接地将电能转化为光能而发光的,而LED则是通过直接将电能转化为光能来发光的。因此,可以说LED属于电-光转换效率非常高的产品。
本文将为您介绍LED中使用的半导体元件的发光原理。
※在本文中,为了区别于“元件(发光元件)”,我们将封装后的产品称为“LED(或LED产品)”。
LED的发光原理
LED(Light Emitting Diode,发光二极管)中元件的基本结构是p型半导体和n型半导体结合而成的“pn结”半导体。
※p型半导体(+:positive 空穴多的半导体)、 n型半导体(-:negative 电子多的半导体)
在该元件上施加正向电压时,空穴(带正电)和电子(带负电)向p-n结方向移动,两者因复合而消失。此时产生的多余能量会被转化为光能,从而实现发光。这种现象称为“复合发光”。
※电子(带负电)和空穴(带正电)复合释放出多余的能量而发光。
发光元件的材料
常见的二极管主要由Si(硅)和 Ge(锗)等材料制成,但这些单质半导体在电子和空穴复合时不容易发光,因此LED使用的是GaN、GaAs、InP等复合时容易发光的化合物半导体。
通过使这些组合的半导体(比如GaAsP、AlGaAs、InGaAlP、AlGaN等组合)在特定的衬底上晶面平行向外推移生长(外延生长)来获取发光元件的功能。
因材料而异的发光颜色
作为LED元件的材料——化合物半导体,会根据其材料的组成和比例而发出各种波长的光(红色和绿色等可见光、红外光、紫外光等)。
另外,发光颜色还会因复合前后的电子能级而异。因多余而被转化为光的能级能量差(带隙能量)越大,光的波长就越短。

关于LED元器件的知识
ED是通过直接将电能转化为光能来发光的。因此,可以说LED属于电-光转换效率非常高的产品。本文介绍了LED中使用的半导体元件的发光原理。
作为LED灯具的“心脏”,LED驱动芯片在实现高效、稳定、智能照明方面发挥着至关重要的作用
现代照明技术的浪潮中,LED驱动芯片以其卓越的性能和广泛的应用前景,正逐渐成为行业的焦点。作为LED灯具的“心脏”,LED驱动芯片在实现高效、稳定、智能照明方面发挥着至关重要的作用。 LED驱动芯片,全称为发光二极管驱动芯片,是一种专为LED灯具设计的集成电路。它的主要功能是精确地控制LED的电流、电压和功率等参数,从而确保LED灯具在各种环境下都能稳定、高效地工作。

打算用1mA电流驱动使LED数字显示器发光,可以吗?
要使用1mA电流驱动的话,建议选用高亮度LED数字显示器。这种情况,应当在电路设计方面采取相应措施,使得实际通过LED元件的电流的偏差不会比设定电流大。另外,还是不提倡用1mA以下电流来驱动LED。

发光二极管久放会坏吗?
发光二极管的久放不会影响发光,唯一受到影响的是引脚生锈问题。受成本限制,直插式发光二极管很少用铜作引脚。一般都用钢质(即我们平时讲的熟铁)材料镀银或镀锡来制作。由于镀层较薄,保管稍有不慎很容易生锈。特别是靠近根部和横杠切口部位,严重时会变脆断掉。
LED数字显示器可以用回流焊接法安装吗?
虽然大部分是不能用回流焊接的产品,但也有可以用回流焊接的产品。被称为LED数字显示器表面贴装型的产品(LF系列)是为回流焊接安装而开发出的产品。不能用回流焊接的产品是采取贯通印刷电路板的方式安装的所谓LED数字显示器双列直插式封装型(LA、LB、LAP、LBP系列)产品。这些产品用射流焊接法或双列直插式封装焊接来安装。关于安装条件,请参阅各种产品的产品规格说明书。
