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. It is widely used in various applications, such as remote controls, surveillance systems, and communication devices. Unlike traditional LEDs, which 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 invisible light is required.

How Does an Infrared LED SMD Work?

An infrared LED SMD works 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 are in the infrared spectrum, which is not visible to the human eye. The intensity of the emitted light depends on the forward voltage and the current flowing through the diode.
