The most common function of a diode is to allow an electric current to pass in one direction (called the diode's forward direction), while blocking it in the opposite direction (the reverse direction).

发光二极管 是一种将电能直接转换成光能的半导体固体显示器件，简称LED (Light Emitting Diode)。 和普通二极管相似，发光二极管也是由一个PN结构成。 发光二极管的PN结封装在透明塑料壳内，外形 …

The device acts as a diode: at one polarity little current is conducted, but a change in polarity generates a much bigger current.

A diode is a specialized electronic component that acts as a one-way switch. It conducts electric current in only one direction and restricts current from the opposite direction.
