light emitting diode (LED)
发光二极管;［发光二极体,光发射二极体］
In semiconductors, a diode which glows when supplied with a specified voltage. LEDs are commonly used as alphanumeric display devices, but can be used as light sources in optical fiber transmission systems, although their low power output and relatively wide make them less attractive than lasers.
一种半导体二极管,当加上规定的电压时会发光。LED一般用作字母数字显示装置,也可以在 光纤传输 系统中当光源使用。由于其输出功率低,相对带宽较宽,所以性能不如激光二极管。 |
