Introduction to Infrared LED Light Technology

What is an Infrared LED Light?

Infrared LED lights, also known as infrared diodes or infrared emitters, are electronic devices that emit light in the infrared spectrum. Unlike visible light, infrared light is not detectable by the human eye, but it can be felt as heat. These lights are widely used in various applications due to their ability to transmit information, provide illumination, and perform specific functions without the need for direct line-of-sight communication.

How Infrared LED Lights Work

Infrared LED lights work on the principle of the semiconductor diode. When an electric current passes through a semiconductor material, such as gallium arsenide or indium phosphide, it excites electrons, causing them to move to higher energy levels. As these electrons return to their original state, they release energy in the form of light. In the case of infrared LEDs, this light falls within the infrared spectrum, which ranges from 700 nanometers to 1 millimeter in wavelength. The process of emitting light from an infrared LED is highly efficient, with a majority of the electrical energy being converted into light. This efficiency makes infrared LED lights a popular choice for various applications, where energy conservation is a priority.
