Introducing the revolutionary technology of invisible infrared LED, a game-changer in the field of lighting and illumination. This innovative LED emits infrared light that is invisible to the naked eye, offering a wide range of applications in various industries. In this article, we will delve into the world of invisible infrared LED, exploring its working principle, advantages, applications, and future prospects.

What is an Invisible Infrared LED?

An invisible infrared LED is a type of light-emitting diode (LED) that emits infrared light at a specific wavelength, making it invisible to the human eye. Unlike traditional LEDs that emit visible light, invisible infrared LEDs produce light in the infrared spectrum, which is beyond the range of human vision. This unique characteristic makes them ideal for applications where visible light is undesirable or prohibited.

Working Principle of Invisible Infrared LED

The working principle of an invisible infrared LED is similar to that of a conventional LED. It consists of a semiconductor material, typically gallium arsenide (GaAs) or indium gallium arsenide (InGaAs), sandwiched between two electrodes. When an electric current is applied, electrons and holes recombine at the junction, releasing energy in the form of infrared light. The key to making the infrared light invisible lies in the specific wavelength emitted by the LED. Infrared light ranges from 700 to 1,000 nanometers (nm), with invisible infrared LEDs typically emitting light at around 850 nm. This wavelength is beyond the range of human vision, making the light invisible.

Advantages of Invisible Infrared LED

Invisible infrared LEDs offer several advantages over traditional visible light LEDs, making them a popular choice in various applications: 1.
