Revolutionizing Night Vision: The Power of Infrared LED Light Technology

Introduction to Infrared LED Light Technology

What is an Infrared LED Light?

An infrared LED light, short for Infrared Light Emitting Diode, is a type of semiconductor device that emits infrared radiation when an electric current is applied to it. Unlike visible light, infrared radiation is not visible to the human eye, but it is detectable by various sensors and devices. Infrared LED lights have found wide applications in numerous industries due to their unique properties and capabilities.

How Does an Infrared LED Work?

The operation of an infrared LED is based on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. In the case of an infrared LED, the emitted light falls within the infrared spectrum, which ranges from 700 nanometers to 1 millimeter in wavelength. When an electric current is applied to the LED, electrons and holes recombine at the junction of the P-N semiconductor, releasing energy in the form of infrared light.
