Introduction to Infrared Power LED Industry

Infrared Power LED: A Brief Overview

The infrared power LED, also known as the infrared LED, is a type of light-emitting diode that emits infrared light. Infrared light is a form of electromagnetic radiation with a wavelength longer than visible light but shorter than microwave radiation. It is widely used in various applications, such as remote controls, security systems, and medical devices. The infrared power LED industry has witnessed significant growth in recent years, driven by the increasing demand for high-performance and energy-efficient infrared devices.

Working Principle of Infrared Power LED

The infrared power LED works on the principle of electroluminescence. When an electric current passes through the diode, it excites the electrons in the semiconductor material, causing them to recombine with electron holes. During this process, energy is released in the form of photons, which are emitted as infrared light. The wavelength of the emitted light depends on the material used in the diode.

Types of Infrared Power LED

There are several types of infrared power LED, categorized based on their material, color, and application. Some of the common types include: 1. AlGaAs (Aluminum Gallium Arsenide) infrared LED: This type of LED is known for its high efficiency and long lifespan. It is widely used in remote controls and security systems. 2. InGaAsP (Indium Gallium Arsenide Phosphide) infrared LED: This type of LED has a longer wavelength than AlGaAs and is used in applications requiring longer-range communication, such as infrared data transmission. 3. InGaAs infrared LED: This type of LED has a shorter wavelength than InGaAsP and is used in applications requiring high sensitivity, such as thermal imaging and night vision devices.
