Introduction to the 3mm Infrared LED Industry

What is an Infrared LED 3mm?

An infrared LED 3mm, also known as an infrared emitting diode, is a type of semiconductor device that emits infrared light when an electric current is applied to it. It is commonly used in various applications such as remote controls, surveillance systems, and communication devices. The 3mm refers to the diameter of the LED, which is a standard size for many infrared LED applications.

How Does an Infrared LED 3mm Work?

Infrared LEDs work on the principle of the photoelectric effect. When an electric current is applied to the semiconductor material, it creates a forward bias, allowing electrons to move from the n-type to the p-type region. As the electrons recombine with the holes, they release energy in the form of photons. These photons have a longer wavelength than visible light, making them infrared. The 3mm size of the infrared LED is a result of the semiconductor material's physical dimensions. The small size makes it suitable for integration into compact devices and applications where space is limited.
