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. The "3mm" refers to the diameter of the LED, which is a standard size for many applications. These LEDs are widely used in various industries due to their compact size, low power consumption, and efficient infrared emission capabilities.

How Does an Infrared LED 3mm Work?

Infrared LEDs work on the principle of the photoelectric effect. When an electric current passes through the semiconductor material, it generates heat, which excites the electrons within the material. These excited electrons then recombine with the holes in the material, releasing energy in the form of photons. The photons emitted have a longer wavelength than visible light, making them infrared. The 3mm size of the LED is ideal for many applications because it allows for compact and efficient design. The small size also makes it easier to integrate into various devices and systems.
