English-Chinese/Light-emitting diode

A light emitting diode (LED) is a semiconductor device that generates light from electricity. LEDs have a long life and are not easily broken (compared to incandescent bulbs). They can produce many different colors. They are highly efficient - most of the energy becomes light rather than heat.

发光二极管（LED）是从电产生光的半导体器件. LED使用寿命长，不易破碎（与白炽灯泡相比）. 它们可以产生许多不同的颜色. 它们非常高效 - 大部分能量变成光而不是热.
