LED infrared technology, often referred to as "LED infrarrojo," has become a pivotal component in various industries due to its efficiency, compact size, and versatility. This article delves into the world of LED infrarrojo, exploring its applications, technological advancements, and the impact it has on modern technology.

Introduction to LED Infrarrojo

LED infrared, or infrared LED, is a type of light-emitting diode (LED) that emits infrared light. Unlike visible light, infrared light is not visible to the human eye and is often used for communication, remote control, and sensing applications. The technology behind LED infrarrojo involves the use of semiconductor materials that emit infrared radiation when an electric current is applied.

How LED Infrarrojo Works

The operation of an LED infrarrojo is based on the principle of electroluminescence. When an electric current is applied to a semiconductor material, such as gallium arsenide (GaAs) or indium gallium arsenide (InGaAs), the electrons and holes within the material recombine, releasing energy in the form of infrared light. The color and intensity of the light depend on the semiconductor material used and the amount of current applied.
