Enhancing Connectivity: The Role of LED Infrared Transmitting Tubes in Modern Technology

LED infrared transmitting tube, also known as an infrared emitting diode, is a semiconductor device that emits infrared light when an electric current passes through it. It has become an essential component in various applications, including consumer electronics, medical devices, and industrial automation. This article aims to provide an in-depth introduction to the LED infrared transmitting tube industry, covering its history, technology, applications, and future prospects.

History of LED Infrared Transmitting Tube

The concept of an infrared emitting diode dates back to the early 20th century. In 1908, a Russian physicist named Oleg Losev discovered that when a selenium crystal was forward biased, it emitted infrared radiation. This discovery laid the foundation for the development of infrared emitting diodes. However, it was not until the 1960s that the first practical infrared emitting diodes were developed by Texas Instruments.

The technology behind LED infrared transmitting tubes has evolved significantly over the years. Initially, the devices were made of materials like selenium and gallium arsenide. Later, the development of gallium nitride (GaN) and aluminum gallium nitride (AlGaN) as semiconductor materials revolutionized the industry. These materials offer higher efficiency, better thermal conductivity, and longer lifespan compared to earlier materials.

Technology of LED Infrared Transmitting Tube

LED infrared transmitting tubes are made of a semiconductor material that emits infrared light when an electric current passes through it. The most common materials used in these devices are gallium nitride (GaN) and aluminum gallium nitride (AlGaN). These materials have a wide bandgap, which allows them to emit infrared light efficiently.

The manufacturing process of LED infrared transmitting tubes involves several steps. First, a p-type and an n-type semiconductor material are deposited on a substrate, typically sapphire or silicon carbide. Then, a p-n junction is formed by doping the materials with impurities. Next, the device is encapsulated in a transparent or reflective material to protect it from external factors and enhance its performance.

The key parameters that determine the performance of an LED infrared transmitting tube include its wavelength, intensity, and efficiency. The wavelength determines the type of infrared light emitted, while the intensity and efficiency indicate the amount of light produced and the energy consumed, respectively.
