5mm IR LED, also known as Infrared Light Emitting Diode, is a compact and efficient light source widely used in various applications such as remote control, surveillance, and communication. In this article, we will explore the industry of 5mm IR LED, including its working principle, advantages, applications, and market trends.

Working Principle of 5mm IR LED

The 5mm IR LED is a semiconductor device that emits infrared light when an electric current passes through it. The core of the 5mm IR LED is a p-n junction, which is formed by diffusing the p-type and n-type materials. When an electric current is applied, electrons and holes are generated at the p-n junction. As the electrons and holes recombine, they release energy in the form of infrared light. The 5mm IR LED has a small size and high brightness, making it suitable for various applications. The working principle of the 5mm IR LED is similar to that of a normal LED, but the difference lies in the wavelength of the emitted light. The 5mm IR LED emits light in the infrared spectrum, which is not visible to the human eye.
