LED infrared transmitting tube, also known as an LED infrared LED, is a crucial component in the field of infrared communication technology. These devices emit infrared light, which is used for various applications such as remote controls, wireless communication, and optical data transmission. This article provides an in-depth introduction to the LED infrared transmitting tube industry, covering its 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 traction. The invention of the LED by Nick Holonyak Jr. in 1962 marked a significant milestone in the development of infrared communication technology. Since then, LED infrared transmitting tubes have evolved significantly, with improvements in efficiency, brightness, and lifespan.

Over the years, the industry has seen several technological advancements. One of the most notable developments was the introduction of surface mount technology (SMT) in the 1980s, which allowed for smaller and more compact infrared transmitting tubes. Additionally, the development of high-brightness LED (HB-LED) technology in the late 1990s further enhanced the performance of infrared transmitting tubes.

Technology and Working Principle

LED infrared transmitting tubes work on the principle of emitting infrared light when an electric current is applied to them. These devices consist of a semiconductor material, typically gallium arsenide (GaAs), which emits light when excited. The emitted light is then focused into a narrow beam using a lens or a reflector, which helps in directing the light towards the receiver.

The key parameters that define the performance of an LED infrared transmitting tube include its wavelength, brightness, and viewing angle. The wavelength determines the color of the emitted light, with common wavelengths ranging from 850 nm to 950 nm. Brightness is measured in milliwatts (mW) and is a crucial factor in ensuring reliable communication over long distances. The viewing angle, on the other hand, defines the range within which the receiver can detect the emitted light.
