Introduction to IR LED Chips

What are IR LED Chips?

IR LED chips, or Infrared Light Emitting Diode chips, are a type of semiconductor device that emits infrared light when an electric current is applied. These chips are widely used in various applications due to their compact size, low power consumption, and ability to emit light in the infrared spectrum. The infrared spectrum is beyond the range of human vision, making IR LED chips ideal for communication, sensing, and other invisible light applications.

How Do IR LED Chips Work?

IR LED chips operate on the principle of the photoelectric effect. When an electric current is passed through the semiconductor material, it generates heat, which excites the electrons within the material. These excited electrons move to a higher energy level and then recombine with the electrons in the valence band, releasing energy in the form of photons. In the case of IR LED chips, these photons are in the infrared spectrum, which is not visible to the human eye.

Types of IR LED Chips

There are several types of IR LED chips available in the market, each designed for specific applications. Some of the common types include:

• AlInGaP IR LED Chips: These chips are known for their high efficiency and are used in applications such as remote controls, barcode scanners, and infrared cameras.
• AlGaAs IR LED Chips: These chips are used in applications that require high brightness, such as IR illuminators and infrared sensors.
• InGaAs IR LED Chips: These chips are known for their long wavelength output and are used in applications such as fiber optic communication and thermal imaging.
