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

How Does an Infrared LED 3mm Work?

Infrared LEDs 3mm work on the principle of 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 infrared light. The 3mm size of the LED ensures that the emitted light is focused and concentrated, making it ideal for applications where precise targeting is required.
