2012 infrared LED, also known as infrared emitting diode, has become a significant component in various applications, especially in the fields of automotive, medical, and consumer electronics. This article aims to provide an in-depth introduction to the 2012 infrared LED industry, covering its history, technology, applications, market trends, and future prospects.

History of 2012 Infrared LED

The concept of infrared LED can be traced back to the early 20th century when scientists discovered that certain materials could emit infrared radiation when stimulated by electricity. However, it was not until the 1960s that the first infrared LED was developed by Nick Holonyak Jr. at General Electric. Since then, infrared LED technology has evolved rapidly, and the 2012 infrared LED has emerged as a popular choice in various applications.

Technology of 2012 Infrared LED

The 2012 infrared LED is a semiconductor device that emits infrared light when an electric current passes through it. The device consists of a p-n junction, where the p-type and n-type semiconductor materials are combined to create a diode. When the diode is forward-biased, electrons and holes recombine at the junction, releasing energy in the form of infrared light. The key parameters of a 2012 infrared LED include its wavelength, emission angle, and radiant intensity. The wavelength determines the color of the emitted light, with shorter wavelengths producing red and longer wavelengths producing infrared light. The emission angle defines the spread of the light, while the radiant intensity represents the total amount of light emitted.
