This article provides an in-depth introduction to the infrared LED industry, covering its history, working principles, applications, market trends, and future prospects.

History of Infrared Light Emitting Diode (LED)

The concept of the light-emitting diode (LED) was first proposed by Oleg Vladimirovich Losev in 1927. However, it was not until the 1960s that infrared LED technology began to gain attention. The development of infrared LED technology was primarily driven by the need for secure and efficient communication systems. In the 1970s, the first commercial infrared LED devices were introduced, and since then, the technology has seen significant advancements.

Working Principles of Infrared Light Emitting Diode (LED)

Infrared LED is a semiconductor device that emits infrared light when an electric current is applied. The working principle of an infrared LED is based on the photoelectric effect. When an electric current passes through the semiconductor material, it creates a forward bias, which allows electrons to move from the n-type region to the p-type region. As electrons recombine with holes, they release energy in the form of photons. The wavelength of these photons falls within the infrared spectrum, which is why the device is called an infrared LED.
