Revolutionizing Infrared Detection: The Power of 940nm IR LED Technology

940nm IR LED, or Infrared Light Emitting Diode, has become an indispensable component in various industries due to its unique characteristics. This article aims to provide an in-depth introduction to the 940nm IR LED industry, covering its basic principles, applications, market trends, and future prospects.

Basic Principles of 940nm IR LED

The 940nm IR LED is a semiconductor device that emits infrared light with a wavelength of 940nm. It is typically made of gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs) materials. The working principle of 940nm IR LED is based on the electron-hole recombination process in the semiconductor material.

When the forward voltage is applied to the 940nm IR LED, electrons and holes in the semiconductor material are injected into the active region. As the electrons and holes recombine, they release energy in the form of photons, resulting in the emission of infrared light. The wavelength of the emitted light is determined by the energy band gap of the semiconductor material.
