LED infrared, or LED IR, has emerged as a crucial technology in various industries due to its numerous advantages over traditional infrared sources. This article aims to provide a comprehensive introduction to the LED infrared industry, covering its history, technology, applications, market trends, and future prospects.

History of LED Infrared Technology

LED infrared technology has a relatively short history, with its development starting in the 1960s. However, it wasn't until the late 1990s that LED infrared technology began to gain traction in the market. This was primarily due to the advancements in semiconductor materials and manufacturing processes, which allowed for the production of high-quality, cost-effective LED infrared devices. The first LED infrared devices were primarily used in consumer electronics, such as remote controls for televisions and other devices. As the technology matured, its applications expanded to various industries, including automotive, medical, and industrial automation.

Technology of LED Infrared

LED infrared technology is based on the principle of emitting infrared light through a semiconductor material. When an electrical current is applied to the semiconductor, it generates heat, which excites the electrons within the material. As the electrons return to their original state, they release energy in the form of infrared light. The key components of an LED infrared device include the semiconductor material, a phosphor coating, and an encapsulant. The semiconductor material determines the wavelength of the emitted infrared light, while the phosphor coating enhances the intensity of the light. The encapsulant protects the internal components from environmental factors, such as moisture and dust. There are several types of semiconductor materials used in LED infrared devices, including gallium arsenide (GaAs), gallium nitride (GaN), and aluminum gallium indium phosphide (AlGaInP). Each material has its own advantages and disadvantages, such as wavelength range, efficiency, and cost.
