Fiber lasers start with diodes that turn electricity into light.

光纤激光器始于将电转化为光的二极管。

This process called forward bias is self perpetuating, it allows the current to readily flow through the diode.

这个被称为正向偏压的过程在加上电压后便会一直持续，它让电流能轻易地流过二极管。

Maybe you're thinking, " Okay nerd, why is OLED or organic light emitting diode such a big deal? "

也许你在想，" 好吧，书呆子，为什么 OLED 这么重要？"

Updating streetlights to use light-emitting diodes makes sense.

更新路灯以使用发光二极管是有意义的。

The TV's glass-like quality is possible due to the use of transparent organic light-emitting diode (OLED) technology.

由于使用了透明有机发光二极管 (OLED) 技术，电视的玻璃般质量成为可能。

Its early form, the diode, consisted of two electrodes in an evacuated glass container.

它的早期形式是二极管，由真空玻璃容器中的两个电极组成。

We use light-emitting diodes and different wavelengths of light to create optimum growing conditions.

我们使用发光二极管和不同波长的光来创造最佳的生长条件。

These diodes can emit light at a variety of wavelengths-but one color they do not produce naturally is white.

这些二极管可以发出多种波长的光，但它们自然不会产生的一种颜色是白色。

Instead of being a cone containing a meristem it will be a cone containing a motor, a light-emitting diode and a battery.

两者都是圆锥结构，不过前者里面有一个分生组织，而后者里面是电机，发光二极管和电池各一个。

And that required creating a combination of diodes that together glowed in red, green, and blue.

这需要创建一个组合的二极管， 它们一起发出红色、 绿色和蓝色的光。
