This article aims to provide an in-depth introduction to the 3mm IR LED market, covering its technology, applications, market trends, and future prospects.

Introduction to 3mm IR LED Technology

The 3mm IR LED is a type of semiconductor device that emits infrared light when an electric current passes through it. It is characterized by its small size, typically with a diameter of 3mm, which makes it highly suitable for space-constrained applications. The wavelength of the emitted light typically ranges from 780nm to 1000nm, which falls within the infrared spectrum.

3mm IR LEDs are made of materials such as gallium arsenide (GaAs), gallium nitride (GaN), or aluminum gallium arsenide (AlGaAs). These materials have high efficiency and stability, which contribute to the excellent performance of 3mm IR LEDs. The devices are usually encapsulated in transparent or semi-transparent materials to protect the semiconductor chip and enhance light output.
