Superior 12V IR LED Solutions – Enhance Your Projects!

12V IR LED, or Infrared Light Emitting Diode, is a type of semiconductor device that emits infrared light when an electric current is applied. It has become increasingly popular in various applications, such as remote controls, surveillance systems, and communication systems. In this article, we will delve into the world of 12V IR LED, exploring its working principle, applications, and future trends.

Working Principle of 12V IR LED

12V IR LED operates on the principle of electroluminescence, which is the process of light emission when an electric current passes through a material. When an electric current is applied to the diode, electrons and holes are separated, and when they recombine, energy is released in the form of infrared light. The wavelength of the emitted light ranges from 700nm to 1000nm, which is beyond the visible spectrum of the human eye.

12V IR LED diodes are made of semiconductor materials such as gallium arsenide (GaAs), gallium phosphide (GaP), and indium gallium arsenide (InGaAs). These materials have a direct bandgap, which allows them to efficiently convert electrical energy into infrared light. The forward voltage of a typical 12V IR LED is around 1.2V to 1.5V, and the current can range from 20mA to 100mA, depending on the specific model.
