Introduction to Infrared LED SMD

What is an Infrared LED SMD?

Infrared LED SMD, or Surface Mount Device, is a type of light-emitting diode that emits infrared light. These devices are widely used in various applications, including remote controls, surveillance systems, and medical devices. Unlike traditional LEDs that emit visible light, infrared LEDs emit light in the infrared spectrum, which is not visible to the human eye. This makes them ideal for applications where visibility is not required, but the detection of infrared light is crucial.

How Does an Infrared LED SMD Work?

An infrared LED SMD operates based on the principle of semiconductor physics. When an electric current is applied to the diode, electrons and holes recombine at the junction, releasing energy in the form of photons. In the case of an infrared LED, these photons fall within the infrared spectrum, which is characterized by wavelengths longer than those of visible light. The diode is designed to emit infrared light efficiently, making it suitable for various applications.
