Introducing IR LED Chips: The Key to Efficient and Reliable Infrared Lighting Solutions

Introduction to IR LED Chips

In the rapidly evolving field of optoelectronics, IR LED chips have emerged as a crucial component in a wide range of applications. IR LED chips, short for Infrared Light Emitting Diodes, are semiconductor devices that emit infrared light when an electric current passes through them. These chips are widely used in consumer electronics, automotive, industrial, and medical sectors for their ability to provide efficient, reliable, and precise infrared lighting solutions.

How IR LED Chips Work

IR LED chips operate on the principle of the photoelectric effect. When a forward voltage is applied across the diode, electrons are excited from the valence band to the conduction band, creating a flow of current. As these electrons recombine with holes, they release energy in the form of photons. In the case of IR LED chips, these photons are in the infrared spectrum, which is not visible to the human eye but can be detected by various sensors and devices.
