LED infrared transmitting tube, also known as an LED infrared diode, is a crucial component in the field of infrared communication and remote control technology. These devices emit infrared light at specific wavelengths, which is then received by infrared sensors or receivers to transmit signals wirelessly. This article aims to provide a comprehensive 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 using infrared light for communication dates back to the early 20th century. However, it was not until the 1960s that LED infrared transmitting tubes began to gain prominence. The invention of the light-emitting diode (LED) by Nick Holonyak Jr. in 1962 laid the foundation for the development of infrared transmitting tubes. Over the years, advancements in semiconductor technology have led to the miniaturization and increased efficiency of these devices.

Technology and Working Principle

LED infrared transmitting tubes are based on the principle of semiconductor physics. They consist of a PN junction, where electrons and holes recombine, releasing energy in the form of photons. The semiconductor material used in these tubes is typically gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs), which emits infrared light at a specific wavelength, usually between 780 nm and 950 nm.

When an electric current is applied to the LED, electrons are injected into the conduction band, and holes into the valence band. As these charge carriers recombine, they emit infrared light. The intensity of the light emitted is directly proportional to the current flowing through the diode. The quality of the infrared light emitted is determined by the material composition, doping levels, and device design.
