Introduction to IR LED 12V

The 12V IR LED, as the name suggests, operates at a voltage of 12 volts. These LEDs emit infrared light, which is not visible to the human eye. The 12V rating is a common voltage for many electronic devices, making the 12V IR LED a practical choice for a wide range of applications. The primary advantage of the 12V IR LED is its ability to provide a high output of infrared light while consuming minimal power, thus ensuring energy efficiency.

Technology of IR LED 12V

The technology behind the 12V IR LED involves the use of semiconductor materials that emit infrared light when an electric current is applied. These materials are typically made from gallium arsenide (GaAs), gallium phosphide (GaP), or indium gallium nitride (InGaN). The process of creating an IR LED involves growing a thin layer of the semiconductor material on a substrate, which is then doped with impurities to create a p-n junction. When an electric current is applied to the p-n junction, electrons and holes recombine, releasing energy in the form of photons. The wavelength of these photons determines the color of the light emitted, with shorter wavelengths corresponding to infrared light. The 12V IR LED is designed to emit light in the near-infrared spectrum, which is ideal for various applications requiring invisible light transmission.
