Infrared LED emitter, as an essential component in various applications, has been widely recognized for its significant role in the development of modern technology. This article aims to provide a comprehensive introduction to the infrared LED emitter industry, covering its history, technology, applications, and future trends.

History of Infrared LED Emitter

The infrared LED emitter has a long history, dating back to the early 20th century. In 1900, Heinrich Hertz discovered the existence of infrared radiation. Later, in 1917, the first infrared LED was invented by Oleg Losev, a Russian physicist. However, it was not until the 1960s that the infrared LED emitter industry began to take off, thanks to the development of semiconductor technology.

Technology of Infrared LED Emitter

Infrared LED emitters are made of semiconductor materials, such as gallium arsenide (GaAs), gallium phosphide (GaP), and indium gallium arsenide (InGaAs). The semiconductor materials are doped with impurities to create a p-n junction, which generates an electric current when forward biased. This electric current excites the electrons in the semiconductor, causing them to recombine with holes, releasing energy in the form of infrared radiation.

The infrared LED emitter's performance is determined by several factors, including its wavelength, brightness, and thermal management. The wavelength of the infrared radiation is determined by the energy bandgap of the semiconductor material. The brightness of the infrared LED emitter is influenced by the quality of the semiconductor material and the design of the LED structure. Thermal management is crucial to ensure the longevity and reliability of the infrared LED emitter, as excessive heat can degrade the performance of the semiconductor material.
