IR LED emitter, short for Infrared Light Emitting Diode emitter, has become an essential component in various industries due to its wide range of applications. As a key technology in the field of optoelectronics, IR LED emitters have revolutionized the way we interact with devices, enabling a seamless and efficient experience. This article aims to provide a comprehensive introduction to the IR LED emitter industry, covering its history, technology, applications, market trends, and future prospects.

History of IR LED Emitters

The concept of IR LED emitter dates back to the early 20th century. In 1907, Henry Joseph Round, a British physicist, discovered that when certain materials are excited by electricity, they emit infrared radiation. 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, the technology has undergone significant advancements, resulting in the high-performance IR LED emitters we see today.

Technology of IR LED Emitters

IR LED emitters are semiconductor devices that emit infrared light when an electric current is applied. They consist of a p-n junction, where the p-type and n-type semiconductor materials are joined together. When electrons from the n-type material move to the p-type material, they release energy in the form of infrared light. The key factors that determine the performance of an IR LED emitter include its wavelength, luminous intensity, and efficiency.

Wavelength: IR LED emitters can be categorized into three main types based on their wavelength: near-infrared (NIR), mid-infrared (MIR), and far-infrared (FIR). NIR LEDs have a wavelength range of 750 to 1600 nm, MIR LEDs have a wavelength range of 2 to 20 μm, and FIR LEDs have a wavelength range of 20 to 1000 μm. Each type of IR LED has its unique applications.

Luminous Intensity: Luminous intensity refers to the amount of light emitted by an IR LED emitter. It is measured in millicandela (mcd) and is an essential factor in determining the effectiveness of an IR LED emitter in its application.

Efficiency: Efficiency is the ratio of the electrical power input to the light output of an IR LED emitter. High-efficiency IR LED emitters are crucial for energy-saving applications, as they convert more electrical power into light.
