Near infrared LED light, also known as near infrared radiation, has gained significant attention in various industries due to its unique properties and applications. This article aims to provide a comprehensive introduction to the near infrared LED light industry, covering its history, technology, applications, market trends, and future prospects.

History of Near Infrared LED Light Technology

The concept of near infrared light has been around for a long time, with early studies dating back to the 19th century. However, it was not until the late 20th century that near infrared LED technology began to develop. The breakthrough came with the invention of the LED (Light Emitting Diode) in the 1960s, which allowed for the efficient generation of light at specific wavelengths, including the near infrared spectrum.

Since then, the technology has evolved rapidly, with significant advancements in material science, semiconductor technology, and manufacturing processes. Today, near infrared LED lights are widely used in various fields, thanks to their high efficiency, long lifespan, and low cost.

Technology Behind Near Infrared LED Lights

Near infrared LED lights are based on the principle of semiconductor physics. When a current is applied to a semiconductor material, electrons and holes recombine, releasing energy in the form of light. The specific wavelength of the light emitted depends on the composition and structure of the semiconductor material.

For near infrared LED lights, the semiconductor material typically used is gallium arsenide (GaAs) or its alloys, such as gallium nitride (GaN). These materials can emit light in the near infrared spectrum, which ranges from 700 to 2500 nanometers. The choice of material and its composition can be tailored to achieve the desired emission characteristics, such as intensity, color, and wavelength.

Manufacturing near infrared LED lights involves several steps, including epitaxy, wafer slicing, dicing, and packaging. Epitaxy is the process of growing a thin layer of semiconductor material on a substrate, which is typically a silicon wafer. The wafer is then sliced into individual chips, which are diced into smaller units. Finally, the chips are packaged and tested to ensure their functionality.
