Optimizing IR LED Source Efficiency: The Future of Infrared Illumination Technology

IR LED source, or Infrared Light Emitting Diode source, has become an integral part of various industries due to its versatility and efficiency. This article aims to provide a comprehensive introduction to the IR LED source industry, covering its history, technology, applications, market trends, and future prospects.

History of IR LED Source

The concept of IR LED source dates back to the early 20th century. In 1907, Henry Joseph Round, a British scientist, discovered that certain materials emit infrared radiation when excited by an electric current. This discovery laid the foundation for the development of IR LED technology. However, it was not until the 1960s that the first practical IR LED was developed by Nick Holonyak Jr., an engineer at General Electric. Since then, IR LED technology has undergone significant advancements, making it a crucial component in various applications.

Technology of IR LED Source

An IR LED source is a semiconductor device that emits infrared light when an electric current passes through it. The basic structure of an IR LED consists of a p-n junction, where electrons and holes recombine, releasing energy in the form of infrared radiation. The key parameters of an IR LED include wavelength, power, and intensity.

The wavelength of an IR LED determines the color of the emitted light. Generally, IR LEDs are categorized into three types based on their wavelength: near-infrared (NIR), mid-infrared (MIR), and far-infrared (FIR). NIR LEDs have a wavelength range of 750 to 3000 nm, MIR LEDs range from 3000 to 5000 nm, and FIR LEDs range from 5000 to 10000 nm.

The power and intensity of an IR LED are critical factors in determining its performance. Higher power and intensity allow for longer detection distances and greater sensitivity. However, excessive power and intensity can lead to overheating and reduced lifespan. Therefore, engineers must carefully balance these parameters to achieve optimal performance.
