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. These devices are widely used in various applications, including remote controls, surveillance systems, and communication systems. The 3mm refers to the diameter of the LED, which is a common size for many infrared applications.

How Does an Infrared LED 3mm Work?

Infrared LEDs work by converting electrical energy into light energy. When an electric current is applied to the diode, it generates heat, which excites the electrons within the semiconductor material. These excited electrons then recombine with the holes in the material, releasing energy in the form of photons. The photons emitted have a wavelength in the infrared spectrum, which is not visible to the human eye. The 3mm size of the infrared LED is a result of the semiconductor material used and the design of the device. The small size allows for easy integration into various applications, making it a popular choice for many designers and engineers.
