Introduction to IR LED SMD

What is IR LED SMD?

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 is applied to it. These devices are widely used in various applications due to their compact size, high efficiency, and long lifespan. The “SMD” in the name refers to the surface mount technology used for their assembly, which allows for a more compact and efficient design compared to traditional through-hole components.

How Does IR LED SMD Work?

IR LED SMD operates based on the principle of electroluminescence. When an electric current is passed through the semiconductor material, electrons and holes are generated. These charge carriers recombine at the junction between the P-type and N-type layers of the semiconductor, releasing energy in the form of photons. In the case of IR LED SMD, these photons have a longer wavelength than visible light, which falls within the infrared spectrum.

The infrared light emitted by the IR LED SMD is not visible to the naked eye, making it ideal for applications where invisible light transmission is required. The wavelength of the infrared light can vary depending on the specific application, with common wavelengths ranging from 780 nm to 980 nm.
