Diode IR, or Infrared Diode, is a crucial component in the field of infrared technology. These devices are designed to emit infrared radiation, which is a form of electromagnetic radiation with wavelengths longer than those of visible light but shorter than those of terahertz radiation. The applications of diode IR technology are vast, ranging from consumer electronics to industrial automation. This article aims to provide an in-depth introduction to the diode IR industry, covering its history, technology, applications, and future prospects.

History of Diode IR Technology

The concept of infrared radiation has been known for centuries, but it was not until the late 19th century that scientists began to understand its properties and potential applications. The first practical infrared diode was developed in the 1950s, which marked the beginning of the diode IR industry. Since then, significant advancements have been made in the technology, leading to the development of various types of diode IR devices.

How Diode IR Works

Diode IR devices work based on the principle of the photoelectric effect. When a semiconductor material, such as silicon or gallium arsenide, is exposed to light, it absorbs the energy and releases electrons, creating an electric current. In the case of diode IR, the semiconductor material is specifically designed to emit infrared radiation when an electric current passes through it. This process is known as electroluminescence.
