Introduction to IR LED Industry
What is an IR LED?
An IR LED, or infrared light-emitting diode, is a semiconductor device that emits infrared light when an electric current is applied. It is widely used in various applications, such as remote controls, security systems, and medical devices. The technology behind IR LED has been evolving rapidly, leading to a growing demand for these devices in the market.
History of IR LED
The concept of the LED was first proposed by Oleg Vladimirovich Losev in 1927. However, it was not until the late 1960s that the first practical IR LED was developed by Nick Holonyak Jr. at General Electric. Since then, the technology has seen significant advancements, and today, IR LEDs are widely used in various industries.
Types of IR LEDs
There are two main types of IR LEDs: near-infrared (NIR) and far-infrared (FIR). NIR LEDs emit light in the range of 750 to 1500 nanometers, while FIR LEDs emit light in the range of 1500 to 3000 nanometers. NIR LEDs are commonly used in applications such as remote controls, while FIR LEDs are used in applications such as thermal imaging and night vision.
Applications of IR LEDs
IR LEDs are used in a wide range of applications across various industries. Some of the most common applications include:
1. Remote Controls: IR LEDs are extensively used in remote controls for TVs, air conditioners, and other home appliances. They work by emitting IR light that is received by the device, allowing users to control the device from a distance.
2. Security Systems: IR LEDs are used in security systems to detect movement. When the LED emits IR light, any object that blocks the light is detected, triggering an alarm.
3. Medical Devices: IR LEDs are used in medical devices for various purposes, such as thermotherapy, phototherapy, and diagnostics. They can be used to heat or cool the body, or to provide illumination for medical procedures.
4. Automotive Industry: IR LEDs are used in automotive applications, such as rear-view cameras, night vision systems, and parking assist systems.
5. Thermal Imaging: FIR LEDs are used in thermal imaging cameras to detect heat signatures. This technology is used in various applications, including building inspections, search and rescue operations, and wildlife monitoring.
