Diode IR, or Infrared Diode, has become an essential component in various industries due to its high efficiency, compact size, and low cost. This article aims to provide an in-depth introduction to the diode IR industry, covering its basic principles, applications, market trends, and future prospects.

Basic Principles of Diode IR

Diode IR is a semiconductor device that emits infrared light when an electric current passes through it. It consists of a P-N junction, which is formed by doping a semiconductor material with impurities. When the P-N junction is forward biased, electrons and holes recombine, releasing energy in the form of infrared radiation. The emitted infrared light has a wavelength ranging from 0.75 to 30 micrometers.

Diode IR has several advantages over traditional light sources, such as incandescent bulbs and fluorescent lamps. Firstly, it has a much shorter lifespan, which means lower maintenance costs. Secondly, it consumes less energy, making it more environmentally friendly. Lastly, diode IR can be easily modulated and controlled, offering various applications in different fields.
