Revolutionizing Night Vision: The Cutting-Edge Power of High Power NIR LED Technology

High power NIR LED, or high power near-infrared light-emitting diode, has become a crucial component in various industries due to its unique properties and wide range of applications. This article aims to provide an in-depth introduction to the high power NIR LED industry, covering its technology, applications, market trends, and future prospects.

Technology of High Power NIR LED

High power NIR LED technology is based on the principle of semiconductor light-emitting diodes. It utilizes the energy band gap of semiconductors to convert electrical energy into light energy. The near-infrared region of the electromagnetic spectrum, which ranges from 750 to 2500 nm, is particularly important for various applications due to its ability to penetrate materials and interact with biological tissues.

High power NIR LED chips are typically made of gallium nitride (GaN) or aluminum gallium nitride (AlGaN) materials, which have excellent optical and electrical properties. The manufacturing process involves epitaxial growth, which involves depositing a thin layer of semiconductor material on a substrate to form a p-n junction. This junction is then forward biased to generate light when an electrical current is applied.

One of the key challenges in high power NIR LED technology is achieving high brightness and efficiency. This is achieved through the use of advanced packaging techniques, such as chip-on-board (COB) and flip-chip, which allow for better heat dissipation and light extraction. Additionally, the use of high-quality materials and optimized design can further enhance the performance of high power NIR LED chips.
