At present, there is no way of imagining life if electric light is a basic right that allows us to carry out the most activities of our daily life, so its importance is irrefutable.
Not only human life is benefited by what the UN calls “basic human right”, but also urban life is helped by electricity. Without this, the streets will be seen in areas that are impassable or little traveled so that when the daylight is gone, the street lighting will enhance the beauty of the cities in all senses and make them work and safe.
However, the cost and expense of energy to illuminate these spaces have become very high. This is due to the current electricity demand and the evolution that has had to happen in order to solve the electricity supply.
All this demand and constant evolution is taking its toll on the environment. Currently, 20% of the energy generated in the world is used to illuminate, which means a release of carbon dioxide sometimes greater than what can be generated by the aviation industry.
This transformation has also left great divisions, the creation of lighting or LED technology is one of them. An alternative, which until now is considered as a viable and economic solution for the environment and our portfolio.
Although its existence dates back to the 60s, LED lighting, thanks to its design, has become an electronic piece that has caused a global effect.
Why LED lighting has boomed? How does it work?
- LED bulbs transform a lower percentage of their energy into heat and more into light. A difference of incandescent light. Therefore the LEDs are super-efficient.
This technology comes from the world of quantum mechanics.
- An LED contains two layers of a special material made of semiconductors. One of these layers contains a lot of energetic electrons while the other is full of holes, which are really chemical bonds between broken atoms.
- The LED light works through holes and electrons, which flow into the area where the two semiconductor layers meet. When the electron collides with a hole in that area, it falls into it, so the chemical bond is restored, creating a spark that releases the energy it was using to move and transformed into bright light.
- Thanks to electronic evolution in the development of new semiconductors, scientists constantly improve this technology, so that every day LEDs are more efficient and bright.
This type of technology dominates the lighting of homes and offices. Each day is implemented in more places, which undoubtedly brings a large environmental gain as well as a monetary saving for the inhabitants, granting them a durability superior to traditional systems.
