Innovative Infrared LED SMD: Revolutionizing Lighting and Sensor Applications

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 visible light, infrared light is not visible to the naked eye, making it ideal for applications where privacy and security are a priority.

How Does an Infrared LED SMD Work?

An infrared LED SMD operates on the principle of the PN junction. When an electric current is applied to the diode, electrons and holes recombine at the junction, releasing energy in the form of infrared light. The wavelength of the emitted light typically ranges from 780 nm to 3,000 nm, which falls within the infrared spectrum.
