1·These light-emitting diodes could simulate red light.
这些发光二极管可以模拟红光。
2·To test their hypothesis, researchers took some electrical lights, actually, they were light-emitting diodes.
为了验证他们的假设，研究人员使用了一些电灯，实际是使用了发光二极管。
3·I touched the wrong pins causing a current reversal and all of the diodes on the circuit board exploded.
我触碰了错误的管脚，从而导致了电流的反转，结果那块电路板上的所有二极管都被烧坏了。
4·Unlike high-technology solutions to reducing energy use, like light-emitting diodes in lamp fixtures, white roofs have a long and humble history.
不同于其他一些高科技的降能措施，譬如发光二极管的灯泡，白色屋顶有着漫长和不起眼的历史。
5·Once you've got that, you also need a driver to control the individual diodes, which means additional circuitry and firmware.
如果你实现了上述两点，你还需要一个控制每个二极管的驱动，这意味着需要更多的电路和固件。
