Infrared LED diodes, also known as infrared light-emitting diodes, are electronic components that emit infrared light when an electric current is applied to them. These diodes are widely used in various applications, including remote controls, security systems, medical devices, and consumer electronics. This article provides an in-depth introduction to the infrared LED diode industry, covering its history, technology, applications, market trends, and future prospects.

History and Development

The concept of the light-emitting diode (LED) was first proposed by Oleg Losev in 1927, but it was not until the 1960s that infrared LEDs were developed. The first infrared LED was created by Nick Holonyak at General Electric in 1962. Since then, the technology has undergone significant advancements, with improvements in efficiency, brightness, and color spectrum.

Technology and Working Principle

Infrared LED diodes work on the principle of electroluminescence, where an electric current is applied to a semiconductor material, causing electrons to recombine with electron holes, releasing energy in the form of light. In the case of infrared LEDs, the emitted light is in the infrared spectrum, which is not visible to the human eye. The key parameters of an infrared LED diode include its wavelength, forward voltage, forward current, and luminous intensity.
