IR LED chips, also known as infrared LED chips, are an essential component in various applications such as consumer electronics, automotive, and industrial automation. These chips emit infrared light, which is invisible to the human eye, and are widely used for communication, sensing, and imaging purposes. This article provides an in-depth introduction to the IR LED chip industry, covering its history, technology, market trends, and future prospects.

History of IR LED Chips

The history of IR LED chips dates back to the 1960s when the first IR LED was developed. Initially, these chips were used in simple applications such as remote controls and night vision devices. Over the years, the technology has evolved significantly, leading to the development of high-performance IR LED chips with improved efficiency and longer lifespan. Today, IR LED chips are an integral part of numerous electronic devices and continue to play a crucial role in various industries.

Technology of IR LED Chips

IR LED chips are made using semiconductor materials such as gallium arsenide (GaAs), gallium phosphide (GaP), and aluminum gallium indium phosphide (AlGaInP). These materials have the ability to emit infrared light when an electric current is applied. The manufacturing process involves several steps, including epitaxy, wafer slicing, and chip packaging. The epitaxy process involves growing a thin layer of semiconductor material on a substrate, which serves as the base for the LED chip. After epitaxy, the wafer is sliced into individual chips, and then these chips are packaged using various techniques to protect them from external factors such as moisture and heat.

Types of IR LED Chips

IR LED chips are available in various types, depending on their applications and specifications. Some of the common types include:
