LED infrared transmitting tube, also known as an LED infrared LED, is a type of semiconductor device that emits infrared light. These devices have become increasingly popular in various industries due to their efficiency, compact size, and long lifespan. This article aims to provide 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 light-emitting diodes (LEDs) to emit infrared light dates back to the early 1960s. However, it was not until the late 1970s that the first LED infrared transmitting tubes were developed. These early devices were large, inefficient, and had a limited lifespan. Over the years, significant advancements have been made in the technology, leading to the development of smaller, more efficient, and longer-lasting LED infrared transmitting tubes.

One of the key milestones in the development of LED infrared transmitting tubes was the invention of the AlGaAs (Aluminum Gallium Arsenide) material in the 1970s. This material allowed for the creation of LEDs with a longer wavelength, which could emit infrared light. Since then, researchers and engineers have continued to improve the efficiency and performance of these devices, making them suitable for a wide range of applications.

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 semiconductor material is typically made of AlGaAs or a similar compound that emits infrared light when excited.

The working principle can be summarized as follows:

1. When an electric current is applied to the LED, electrons and holes are injected into the semiconductor material.
2. These electrons and holes recombine within the material, releasing energy in the form of photons.
3. The photons have a longer wavelength, typically in the infrared spectrum, and are emitted from the LED.

The efficiency of an LED infrared transmitting tube is determined by several factors, including the quality of the semiconductor material, the design of the LED structure, and the cooling system. Advances in these areas have led to the development of highly efficient and reliable infrared transmitting tubes.
