Revolutionizing Communication: The Advancements and Applications of Infrared Emitter Tube LED Technology

Infrared emitter tube LED, also known as infrared emitting diode, is a type of semiconductor device that emits infrared radiation when an electric current passes through it. This technology has found wide applications in various fields, including consumer electronics, automotive, medical, and industrial sectors. This article aims to provide an in-depth introduction to the infrared emitter tube LED industry, covering its history, technology, applications, market trends, and future prospects.

History of Infrared Emitter Tube LED

The concept of the infrared emitting diode dates back to the early 20th century. In 1906, a Russian physicist named Oleg Losev discovered that certain semiconductors, such as silicon and selenium, emitted infrared radiation when forward biased. This discovery marked the birth of the infrared emitting diode. However, it was not until the 1960s that the technology started to gain attention due to its potential applications in various industries.

In the 1970s, the first practical infrared emitting diodes were developed. These devices were primarily used in remote controls for television sets and other consumer electronics. Since then, the technology has evolved significantly, with improvements in efficiency, brightness, and lifespan. Today, infrared emitter tube LEDs are widely used in a variety of applications, making them an essential component in modern technology.

Technology of Infrared Emitter Tube LED

The infrared emitter tube LED is a semiconductor device that consists of a PN junction. When an electric current is applied to the junction, electrons and holes recombine, releasing energy in the form of infrared radiation. The wavelength of the emitted light depends on the composition and structure of the semiconductor material used.

The main materials used in the manufacturing of infrared emitter tube LEDs include gallium arsenide (GaAs), gallium phosphide (GaP), and indium gallium arsenide phosphide (InGaAsP). These materials have different bandgap energies, which determine the wavelength of the emitted light. For instance, GaAs emits infrared light at a wavelength of around 930 nm, while InGaAsP emits light at a wavelength of around 1550 nm.

The manufacturing process of infrared emitter tube LEDs involves several steps, including epitaxial growth, doping, and packaging. Epitaxial growth is used to create a thin layer of semiconductor material on a substrate. Doping involves adding impurities to the semiconductor material to alter its electrical properties. Finally, the device is packaged and tested to ensure its functionality.
