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。

An electronic component that permits the one-way flow of current is called a diode, but what was really needed was a switch to help turn this flow on and off.

任何只允许电流单向流动的电子部件都叫做二极管，但我们还需要一个开关来开关电路。

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

Much of the light these cells used would, of necessity, come from incandescent bulbs, fluorescent tubes and light-emitting diodes (LEDs) rather than through the window from the sun.

它们所用的光能中的大部分势必来自白炽灯，日光灯和发光二极管，而并非透过窗户照射进来的太阳光。

Using diodes and transistors from Radio Shack, and with the help of a music student in his dorm who had perfect pitch, he got it built before Thanksgiving.

他从电器连锁店Radio Shack买来二极管和晶体管，在同宿舍一个拥有准感的学生的帮助下，在感恩节之前就成了制作。

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？"

Once there, the liquid will be solidified by ultraviolet rays from the diode, extending the cylinder and forcing the cone farther into the soil.

液态塑料到达该位置后马上会因二极管发出的紫外线照射凝固，使圆柱体增长，促使锥体在土壤中更进一步。

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。

Published in 2018, entitled Light-Emitting Diodes in Dermatology, A Systematic Review of Randomized Controlled Trials.

2018年发表的，题为《皮肤科中的发光二极管：随机对照试验系统回顾》。

The new 9 Series Tractors let you select the visibility package that best meets your needs Select, Premium, or Ultimate with 360-degree light-emitting diode (LED) lighting - so you and your operators can run confidently in all conditions.

新的9系列拖拉机让你可以选择最符合你需要的视野套装：标准版、高级版或终极版，配备360度发光二极管（LED）照明系统——这样你和你的操作员可以在所有条件下自信地运行。

We use a one way diode essentially for  single direction communication, and so there's no way to access the plant computers  from off site.

我们基本上使用单向二极管进行单向通信，因此无法从异地访问工厂计算机。

Typically these contain a pair of stereoscopic lenses and a light-emitting diode or LED display screen.

通常这些设备包含一对立体镜和一个发光二极管或LED显示屏。

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。

For example, the ENIAC, consisted of more than 17,000 vacuum tubes, 70,000 resistors, 10,000 capacitors, and 7,000 diodes, all of which required 5 million hand-soldered connections.

例如，ENIAC由超过17000根真空管、70000个电阻器、10000个电容器和7000个二极管组成，所有这些都需要进行5百万个手工焊接连接。

Nakamura for developing the blue light emitting diode, or LED. This ridiculously useful invention is the key to making possible the white LED bulb.

Nakamura 开发了蓝色发光二极管或 LED。这个非常有用的发明使白色 LED 灯泡成为可能的关键。

An LED is a type of diode or semiconductor device that emits light when electrons flow through layers of crystalline inorganic material.

LED 一种二极管或半导体器件，当电子流过结晶无机材料层时会发光。

These diodes have been around since the 1950s, but at first we were only able to make ones that emitted either red or green light.

这些二极管自 1950 年代就已问世，但起初我们只能制造发出红光或绿光的二极管。

I'm taking you back to Japan in 1993, when a literal lightbulb moment led to the invention of the first white light-emitting diode, which you'll know as the LED.

我带你回到1993年的日本，当时一个灵光一闪的时刻导致了首个白色发光二极管的发明，也就你所熟知的LED。

In fact, the 2014 Nobel Prize in Physics was awarded to three researchers for their discovery of efficient blue light-emitting diodes.

事实上，2014年诺贝尔物理学奖颁发给了三位研究人员，以表彰他们发现高效蓝光发光二极管。
