Introduction to IR LED Light Technology

What is an IR LED Light?

IR LED lights, or Infrared Light Emitting Diodes, are a type of semiconductor device that emits infrared light when an electric current is applied. Unlike visible light, infrared light is not visible to the human eye, but it is detectable by certain sensors and devices. IR LED lights are widely used in various applications due to their efficiency, compact size, and long lifespan. They are a crucial component in many modern technologies, from consumer electronics to industrial automation.

How IR LED Lights Work

IR LED lights work on the principle of the PN junction. When an electric current is passed through the PN junction, electrons recombine with electron holes, releasing energy in the form of photons. In the case of IR LED lights, these photons have a longer wavelength than visible light, typically ranging from 700 to 3000 nanometers. The specific wavelength of the emitted light depends on the material used in the LED and the desired application.
