Introduction to 3mm Light Emitting Diode (LED)

A 3mm Light Emitting Diode (LED) is a type of semiconductor device that emits light when an electric current passes through it. These LEDs are characterized by their small size, low power consumption, and high efficiency. The 3mm LED is a popular choice for various applications due to its compact size, making it suitable for integration into tight spaces.

How Does a 3mm LED Work?

The working principle of a 3mm LED is based on the photoelectric effect. When an electric current is applied to the semiconductor material, it creates a flow of electrons. As these electrons move through the material, they collide with atoms, releasing energy in the form of photons. This process generates light, which is emitted from the LED. The color of the light emitted by a 3mm LED depends on the type of semiconductor material used. Common colors include red, green, blue, and yellow. These colors can be mixed to create a wide range of hues, making 3mm LEDs versatile for various applications.
