12V IR LED, or Infrared Light Emitting Diode, has become an integral part of various industries due to its unique properties and applications. This article aims to provide a comprehensive introduction to the 12V IR LED industry, covering its history, technology, applications, and future trends.

History of 12V IR LED

The history of 12V IR LED can be traced back to the early 20th century when the first light-emitting diode (LED) was invented. However, it was not until the late 1960s that the first infrared LED was developed. Since then, the technology has evolved significantly, with the 12V IR LED becoming a popular choice for various applications due to its high efficiency and long lifespan.

Technology of 12V IR LED

12V IR LED is a semiconductor device that emits infrared light when an electric current is applied. The key components of a 12V IR LED include a semiconductor material, a p-n junction, and a metal contact. When an electric current passes through the p-n junction, the electrons and holes recombine, releasing energy in the form of infrared light.

12V IR LED is available in various colors, with the most common being red, near-infrared, and far-infrared. The color of the LED is determined by the energy gap of the semiconductor material used. The energy gap is the difference in energy between the valence band and the conduction band of the semiconductor material.
