Introduction

The infrared 940nm lamp, also known as the 940nm infrared LED, has become an essential 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 infrared 940nm lamp, including its working principle, advantages, applications, and market trends.

Working Principle of Infrared 940nm Lamp

The infrared 940nm lamp emits infrared radiation with a wavelength of 940nm. This type of infrared radiation is invisible to the human eye, making it ideal for various applications that require covert or unobtrusive operation. The working principle of the 940nm infrared lamp is based on the semiconductor material, typically gallium arsenide (GaAs), which emits infrared radiation when an electric current passes through it. The semiconductor material is sandwiched between two electrodes, and when a voltage is applied across the electrodes, electrons are excited and move to higher energy levels. As these electrons return to their original energy levels, they release energy in the form of photons, which are emitted as infrared radiation. The 940nm wavelength is a result of the specific energy bandgap of the GaAs material.
