History of Infrared IR LED

The invention of the infrared IR LED can be traced back to the 1960s. At that time, scientists discovered that when a semiconductor material was excited by electricity, it could emit infrared light. This discovery laid the foundation for the development of infrared IR LED.

In the early days, infrared IR LED was mainly used in remote control devices. With the continuous improvement of technology, the application scope of infrared IR LED has been expanding. Today, it has become an essential part of our daily life, such as in mobile phones, cameras, and security systems.

Working Principle of Infrared IR LED

The working principle of infrared IR LED is based on the semiconductor physics. When the semiconductor material is excited by electricity, electrons and holes are generated. The recombination of electrons and holes will emit infrared light. The energy level of the emitted light is determined by the material and the structure of the semiconductor.

The infrared IR LED is usually made of gallium arsenide (GaAs), gallium phosphide (GaP), and other semiconductor materials. These materials have a direct band gap, which makes it possible to emit infrared light.
