Infrared emitter tube LED, also known as infrared LED, is a type of semiconductor light-emitting diode that emits infrared light. These devices are widely used in various applications, including remote controls, communication systems, and security systems. This article provides 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 LED dates back to the early 20th century when the first semiconductor diodes were developed. However, it was not until the late 1960s that infrared LEDs were first introduced. These early devices were limited in terms of efficiency and power output but laid the foundation for the development of modern infrared emitter tube LEDs. The first practical infrared LED was developed by Nick Holonyak Jr. at General Electric in 1962. This breakthrough enabled the creation of practical devices for various applications. Over the years, the technology has evolved significantly, with improvements in efficiency, lifespan, and cost-effectiveness.

Technology of Infrared Emitter Tube LED

Infrared emitter tube LEDs are made using a similar process to traditional LEDs. They consist of a semiconductor material, typically gallium arsenide (GaAs), gallium phosphide (GaP), or aluminum gallium arsenide (AlGaAs), which emits infrared light when an electric current is applied. The structure of an infrared emitter tube LED typically includes a p-n junction, where the p-type and n-type semiconductor materials meet. When an electric current flows through this junction, electrons recombine with holes, releasing energy in the form of infrared light. The specific wavelength of the emitted light depends on the composition of the semiconductor material. Modern infrared emitter tube LEDs are available in various configurations, including through-hole, surface mount, and array packages. They come in different sizes and power outputs to suit various applications.
