With the rapid development of technology, infrared power LED has become an essential component in various fields. This article aims to provide an in-depth introduction to the infrared power LED industry, covering its history, technology, applications, and future trends.

History of Infrared Power LED

The concept of infrared power LED originated in the 1960s when scientists began to explore the potential of light-emitting diodes (LEDs) in various applications. In the early 1970s, the first infrared power LED was developed, marking the beginning of a new era in the field of optoelectronics. Since then, the technology has undergone significant advancements, leading to the development of high-efficiency, long-life infrared power LEDs.

Technology of Infrared Power LED

Infrared power LED is a type of semiconductor device that emits infrared radiation when an electric current is applied. The device consists of a p-n junction, where electrons and holes recombine, releasing energy in the form of infrared light. The key factors that determine the performance of an infrared power LED include its material, structure, and packaging. The material used in infrared power LED is typically gallium arsenide (GaAs) or its alloys, such as gallium phosphide (GaP) and aluminum gallium arsenide (AlGaAs). These materials have high optical and electrical properties, making them ideal for infrared emission. The structure of an infrared power LED typically includes a p-type layer, an n-type layer, and a cladding layer to enhance the light extraction efficiency. The packaging of an infrared power LED is crucial for its performance. Various packaging technologies, such as chip-on-board (COB), chip-on-glass (COG), and surface mount technology (SMT), have been developed to improve the thermal management, light extraction, and mechanical stability of the device.
