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 electronic component that emits infrared light. It is widely used in various applications, including remote controls, sensors, and communication systems. Unlike traditional LEDs, which emit visible light, IR LEDs emit light in the infrared spectrum, which is not visible to the human eye.

How does an IR LED SMD work?

An IR LED SMD operates on the principle of electroluminescence. When an electric current passes through the semiconductor material within the LED, it emits photons in the infrared spectrum. The semiconductor material used in IR LEDs is typically made of gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs). These materials have a direct bandgap, which allows them to emit infrared light efficiently.
