LEDs (Light Emitting Diodes) are an important type of electronic device that can be utilized in a variety of applications. An LED obtained using the model AA3528AVU/AYS is a type of LED that can be used in circuit board indicators, arrays, light bars, bar graphs, and other applications. This article will discuss the application field and working principle of LED AA3528AVU/AYS.

How Do LEDs Work?

LEDs are formed by combining two semiconductors together – one of them carries a positive charge, the other carries a negative charge. When a voltage is applied, electrons from the negative semiconductor flow over to the positive one in what\'s known as a diode-like potential barrier. This generates light, which is then made visible by a transparent encapsulation that covers the outside of the LEDs.

The color of the light generated by the LED is determined by the semiconductors used. For example, a common semiconductor used for constructing green LEDs is gallium arsenide phosphide. Red LEDs are based on gallium arsenide phosphide (GaAsP), while orange ones are based on gallium aluminum arsenide (GaAlAs).

Application Field and Working Principle of LED AA3528AVU/AYS
