With the rapid development of technology, infrared (IR) lighting has become an indispensable part of our daily lives. Among the various types of IR LEDs, 880nm IR LEDs have gained significant attention due to their unique properties and wide applications. This article aims to provide an in-depth introduction to the 880nm IR LED industry, covering its technology, applications, market trends, and future prospects.

Introduction to 880nm IR LED

880nm IR LED, also known as near-infrared LED, is a type of light-emitting diode that emits light at a wavelength of 880nm. It belongs to the infrared spectrum, which is invisible to the human eye. Compared with other types of IR LEDs, 880nm IR LEDs have higher brightness, longer lifespan, and lower power consumption. These characteristics make them ideal for various applications, such as remote control, biometric identification, and medical equipment.

Technology of 880nm IR LED

The technology of 880nm IR LED involves the design and manufacturing of semiconductor materials, which are responsible for emitting light. The most commonly used semiconductor materials for 880nm IR LEDs are gallium nitride (GaN) and aluminum gallium nitride (AlGaN). These materials have excellent optical and electrical properties, which enable the production of high-quality IR LEDs.

During the manufacturing process, the semiconductor materials are epitaxially grown on a substrate, and then a p-n junction is formed. The p-n junction is the core of the LED, where the electrons and holes recombine to emit light. The quality of the p-n junction directly affects the performance of the 880nm IR LED.

In addition to the semiconductor materials, the encapsulation technology is also crucial for the performance of 880nm IR LEDs. The encapsulation material should have good thermal conductivity, optical transparency, and mechanical strength. Common encapsulation materials include epoxy, silicone, and phosphorus.
