In this article, we will delve into the world of 5mm infrared LEDs, exploring their features, applications, and the market trends that drive their demand.

Understanding Infrared LED 5mm

An infrared LED 5mm is a type of semiconductor device that emits infrared light when an electric current is applied to it. The term "5mm" refers to the diameter of the LED's lens, which is typically 5 millimeters. These LEDs are available in various colors, with the most common being red, amber, and clear. The infrared light emitted by these LEDs is invisible to the human eye, making them ideal for applications that require stealth or covert communication.

Working Principle of Infrared LED 5mm

The working principle of an infrared LED 5mm is based on the photoelectric effect. When an electric current is applied to the LED, electrons are excited and move from the valence band to the conduction band. As these electrons recombine with holes in the valence band, they release energy in the form of photons. In the case of an infrared LED, these photons are in the infrared spectrum, which is outside the visible range of human eyes.
