Introduction to Infrared Power LED Industry

What is an Infrared Power LED?

An infrared power LED, also known as an infrared LED, is a type of light-emitting diode that emits infrared radiation. Unlike visible light, infrared radiation is not visible to the human eye. It falls within the electromagnetic spectrum between microwaves and visible light. Infrared power LEDs are widely used in various applications due to their unique properties and advantages.

Working Principle of Infrared Power LED

The working principle of an infrared power LED is based on the semiconductor material, typically gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs). When an electric current passes through the semiconductor material, electrons and holes recombine, releasing energy in the form of photons. These photons have longer wavelengths than visible light, which corresponds to the infrared region of the electromagnetic spectrum. The infrared power LED consists of a p-n junction, where the p-type and n-type regions are formed by doping the semiconductor material with impurities. The forward bias voltage applied across the p-n junction causes electrons to move from the n-type region to the p-type region, leading to the recombination process and the emission of infrared radiation.

Applications of Infrared Power LED

Infrared power LEDs have a wide range of applications in various industries. Some of the key applications include: 1. Remote Control Devices: Infrared power LEDs are commonly used in remote control devices such as televisions, air conditioners, and audio systems. They emit infrared radiation that is received by a sensor, allowing the device to respond to the user's commands. 2.
