Introduction to Broadband IR LED Industry

1. Definition and Overview of Broadband IR LED

Broadband infrared light-emitting diodes (IR LEDs) are a type of semiconductor devices that emit infrared light in a broad spectrum. Unlike traditional IR LEDs, which emit light in a narrow bandwidth, broadband IR LEDs can emit light with a wider wavelength range, ranging from 700nm to 3000nm. This characteristic makes them highly versatile and suitable for various applications, such as remote control, night vision, and communication systems.

2. Working Principle of Broadband IR LED

The working principle of a broadband IR LED is based on the semiconductor material's ability to emit light when an electric current passes through it. The semiconductor material used in broadband IR LEDs is typically gallium arsenide (GaAs) or indium gallium arsenide (InGaAs), which has a direct bandgap structure. When the current passes through the material, electrons and holes recombine, releasing energy in the form of photons. The wavelength of the emitted photons depends on the energy bandgap of the semiconductor material, which determines the color and bandwidth of the emitted light.

3. Applications of Broadband IR LED

The broad spectrum of broadband IR LEDs makes them suitable for various applications in different industries. Some of the common applications include: - Remote Control: Broadband IR LEDs are widely used in remote control devices, such as televisions, air conditioners, and audio systems.
