Wide Angle IR LED: A Game-Changer in the Field of Infrared Illumination

Introduction to Wide Angle IR LED

Wide Angle IR LED, also known as Infrared Light Emitting Diode, has emerged as a revolutionary technology in the field of infrared illumination. With its wide-angle beam and high-intensity output, Wide Angle IR LED has become an essential component in various applications, including security, surveillance, and medical fields. This article aims to provide an in-depth introduction to Wide Angle IR LED, its working principle, advantages, and applications.

Working Principle of Wide Angle IR LED

The Wide Angle IR LED operates on the principle of electroluminescence, which is the process of emitting light when an electric current passes through a semiconductor material. In the case of Wide Angle IR LED, the semiconductor material used is Gallium Arsenide (GaAs) or Aluminum Gallium Arsenide (AlGaAs), which emits infrared light when an electric current is applied. The working principle of Wide Angle IR LED can be summarized as follows: 1. Electric current is applied to the semiconductor material, causing electrons to move through the material. 2. As the electrons move, they collide with the atoms in the semiconductor material, releasing energy in the form of photons. 3. These photons have a wavelength in the infrared region, which is not visible to the human eye. 4. The emitted infrared light is then focused into a wide-angle beam by the lens or reflector attached to the LED.
