Introducing IR LED Chips: The Heart of Infrared Illumination Technology

Introduction to IR LED Chips

In the realm of optoelectronics, IR LED chips play a pivotal role in various applications, serving as the backbone of infrared illumination technology. These chips are designed to emit infrared light, which is invisible to the human eye but essential for numerous electronic devices. The demand for IR LED chips has surged in recent years, driven by advancements in technology and the growing need for efficient and reliable infrared solutions.

How IR LED Chips Work

IR LED chips, also known as infrared light-emitting diodes, are semiconductor devices that emit light in the infrared spectrum. They are composed of a p-n junction, which generates light when an electric current is applied. The process involves the recombination of electrons and holes within the semiconductor material, resulting in the emission of photons. These photons fall within the infrared region of the electromagnetic spectrum, making them invisible to the naked eye. The working principle of IR LED chips is based on the bandgap of the semiconductor material used. Different materials have different bandgap energies, which determine the wavelength of the emitted light. For example, gallium arsenide (GaAs) and aluminum gallium arsenide (AlGaAs) are commonly used materials for IR LED chips due to their ability to emit light in the near-infrared region (700 to 1600 nm).
