Introduction to IR LED SMD

What is an IR LED SMD?

An IR LED SMD, which stands for Infrared Light Emitting Diode Surface Mount Device, is a type of semiconductor device that emits infrared light when an electric current passes through it. These devices are widely used in various applications due to their compact size, high efficiency, and reliable performance. The SMD technology allows for the integration of the LED into a smaller package, making it suitable for space-constrained environments.

How Does an IR LED SMD Work?

An IR LED SMD operates based on the principle of electroluminescence. When an electric current is applied to the semiconductor material, it generates heat, which excites the electrons. These excited electrons recombine with the electron holes, releasing energy in the form of photons. In the case of an IR LED SMD, these photons are in the infrared spectrum, which is not visible to the human eye.

The semiconductor material used in IR LED SMDs is typically made of gallium arsenide (GaAs) or indium gallium arsenide (InGaAs). These materials have a direct bandgap, which allows for efficient emission of infrared light. The size of the LED is determined by the size of the semiconductor material and the package design.
