12V IR LED, or Infrared Light Emitting Diode, has become an essential component in various industries due to its wide range of applications and superior performance. This article aims to provide an in-depth introduction to the 12V IR LED industry, covering its history, technology, applications, market trends, and future prospects.

History of 12V IR LED

The concept of infrared technology dates back to the early 20th century. However, it was not until the 1960s that infrared diodes were developed, marking the beginning of the IR LED industry. Since then, the technology has undergone significant advancements, leading to the emergence of 12V IR LEDs. These diodes have become increasingly popular due to their compact size, low power consumption, and long lifespan.

Technology of 12V IR LED

12V IR LEDs are semiconductor devices that emit infrared light when an electric current passes through them. They consist of a p-n junction, where the p-type material has an excess of positive charge carriers (holes), and the n-type material has an excess of negative charge carriers (electrons). When the diode is forward biased, electrons and holes recombine at the junction, releasing energy in the form of infrared light.

12V IR LEDs come in various types, including AlGaAs, GaAs, and InGaAs. The choice of material depends on the desired wavelength and power output. For instance, AlGaAs-based IR LEDs are commonly used for short-range applications, while GaAs-based LEDs are suitable for medium-range applications.
