luminescence diode的用法和樣例：
例句
- The display may be liquid crystal or light emitting diode.
可以採用液晶或發光二極體顯示。 - When powering a light emitting diode, a comparatively large current flows through the resistor, so you need to consider the power rating of the resistor you choose.
當為發光二極體供電時，會有相對較強的電流通過電阻器，因而要考慮所選擇的電阻器的額定功率。
