Ir diode, short for infrared diode, is a semiconductor device that emits infrared light when an electric current is applied. It is widely used in various fields such as remote control, optical communication, and medical diagnosis. This article will introduce the industry of ir diode, including its history, working principle, applications, and market trends.

History of Ir Diode

The concept of infrared diode was proposed by the American physicist John Bardeen in the 1950s. However, it was not until the 1960s that the first practical infrared diode was developed. Since then, the technology of infrared diode has been rapidly developed and has become an essential component in many electronic devices.

Working Principle of Ir Diode

Ir diode is a semiconductor device composed of a P-N junction. When an electric current is applied to the P-N junction, electrons and holes are generated due to the recombination of electrons and holes. The energy released during the recombination is converted into infrared light. The wavelength of the emitted infrared light depends on the composition and structure of the semiconductor material.

Applications of Ir Diode

Ir diodes have a wide range of applications in various fields:

• Remote control: Ir diodes are commonly used in remote controls for televisions, air conditioners, and other electronic devices. They can transmit infrared signals to control the devices from a distance.

• Optical communication: Ir diodes are used in optical communication systems, such as fiber optic networks and wireless optical communication. They can convert electrical signals into optical signals for long-distance transmission.

• Medical diagnosis: Ir diodes are used in medical devices for non-invasive diagnosis, such as thermal imaging and endoscopy. They can detect infrared radiation emitted by the human body to obtain information about internal organs and tissues.

• Security and surveillance: Ir diodes are used in security and surveillance systems for infrared detection and night vision. They can detect infrared radiation emitted by objects or human beings to provide security protection.

Market Trends of Ir Diode

The market of ir diode has been growing rapidly in recent years due to the increasing demand in various applications. The following are some of the key market trends:

• High-power and high-efficiency: As the demand for high-power and high-efficiency devices increases, the development of high-power and high-efficiency ir diodes is becoming more important.
