Introduction to IR LED Industry

What is an IR LED?

An IR LED, or Infrared Light Emitting Diode, is a type of semiconductor device that emits infrared light when an electric current is applied to it. Unlike visible light LEDs, which emit light that can be seen by the human eye, IR LEDs emit light in the infrared spectrum, which is beyond the visible range. This makes them ideal for applications where invisible light is required, such as in remote controls, security systems, and medical devices.

How Does an IR LED Work?

IR LEDs operate on the principle of the semiconductor junction. When an electric current passes through the junction, it excites the electrons, causing them to move to a higher energy level. As these electrons return to their original state, they release energy in the form of photons. In the case of IR LEDs, these photons fall within the infrared region of the electromagnetic spectrum, typically ranging from 780 nm to 3,000 nm.

Applications of IR LEDs

IR LEDs have a wide range of applications across various industries. Some of the most common uses include:

• Remote Controls: IR LEDs are commonly used in remote controls for TVs, air conditioners, and other electronic devices. They emit infrared signals that are received by a sensor in the device, allowing for wireless control.

• Security Systems: IR LEDs are used in motion detection systems, where they emit infrared light that can detect changes in the environment, triggering an alarm if movement is detected.

• Medical Devices: In medical applications, IR LEDs are used for various purposes, such as thermal imaging, endoscopy, and phototherapy.

• Automotive Industry: IR LEDs are used in automotive lighting, including taillights, brake lights, and turn signals, where they provide a distinct and efficient light source.

• Consumer Electronics: IR LEDs are used in gaming controllers, cameras, and various other consumer electronics for features like autofocus and night vision.
