What does the acronym LED mean according to the EGLO guide?

According to the EGLO guide, the acronym LED stands for Lighting Emitting Diode.

This technology is based on the use of diodes, which are electrical components capable of converting electrical energy directly into light. Unlike traditional light bulbs, these devices do not use filaments or polluting gases such as mercury; Instead, they are made up of several layers of silicone and chemical elements such as indium, gallium and nitrogen, the combination of which determines the colour of the light obtained.

The guide highlights that, although its main function is to illuminate just like a conventional halogen, LED does so in a much more sustainable, durable and versatile way.

Metaphor to understand the concept: Imagine that an LED is like a small electronic piano: while an old light bulb is like burning wood to produce noise (heat and light), the LED produces the "note" of light directly and precisely by pressing an electric key, without wasting energy on secondary processes.
