LED infrared transmitting tube, also known as an LED infrared diode, is a crucial component in various applications, particularly in the fields of remote control, security systems, and medical devices. These devices emit infrared light that is used for communication and detection purposes. This article provides an in-depth introduction to the industry of LED infrared transmitting tubes, covering their history, technology, applications, market trends, and future prospects.

History and Development

The concept of the LED infrared transmitting tube dates back to the early 20th century when infrared technology was first introduced. However, it was not until the late 1960s that the first practical LED infrared diode was developed by Nick Holonyak Jr. at General Electric. Since then, the technology has undergone significant advancements, leading to the development of high-efficiency, compact, and durable LED infrared transmitting tubes.

Technology and Working Principle

LED infrared transmitting tubes work on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. In the case of infrared transmitting tubes, the emitted light is in the infrared spectrum, which is not visible to the human eye. The semiconductor material used in these tubes is typically a combination of gallium arsenide (GaAs), gallium phosphide (GaP), or aluminum gallium arsenide (AlGaAs), which are chosen for their ability to emit infrared light efficiently.

The working principle involves the injection of electrons and holes into the semiconductor material. When these charge carriers recombine, they release energy in the form of photons. The energy released depends on the energy bandgap of the semiconductor material, which determines the wavelength of the emitted light. In the case of LED infrared transmitting tubes, the wavelength typically ranges from 780 to 950 nanometers.
