LED lighting: the light of today and tomorrow

NASA estimates that the Sun takes more than four and a half billion years to illuminate the Milky Way, being the brightest star in the sky. In the prehistoric era, it was conceived as a unique luminescent element of the inhabitants of the Earth. Its natural light governed the cycles, the time, until the first humans discovered the fire.

 

Over the years, appeared new light sources, such as candles, oil lamps or classic chandeliers, then came coal gas, kerosene or petroleum distillation.

Since then, lighting has evolved to even be conceived as an element of aesthetics. Today, intelligent lighting has come to be: The light of the present and the future.

I have written a few articles in the past on led lighting, explaining the benefits of LED lighting and suggesting that we should be changing to this type of lighting, especially due to the large saving on energy and therefore in the electricity bill.

 

Since those articles the prices of LED bulbs and strips  have been reduced drastically so now, there are no excuses not to change over to LED. 

Of world electricity generation, 19% is intended for lighting, according to the International Energy Agency (IEA). For its part, the multinational Philips ensures that switching to more efficient lighting systems would save Europe the astronomical figure of 4.300.000.000 Euros, equivalent to 50,000,000 barrels of oil per year or one billion trees, which would avoid 28.000.000 of tons of CO2 emissions.

 

So, by just switching to more efficient lighting systems could prevent 28.000.000 of tons of CO2 emissions in Europe.

For this reason, increasing the efficiency of lighting devices and reducing unnecessary consumption not only would help to reduce the electricity bill, but also to protect the environment. In this sense, research centres and companies in the sector work in the development of new technologies.

LED lights (Light Emission Diode, or light-emitting diode) are known since the 1960s and became popular as bright red and green spots in numerous electronic devices. Technological advances are expanding the uses of LEDs, and are nowadays used increasingly as the lighting in public places, buildings, giant screens advertising, traffic lights or lanterns for extreme sports. Also, starting in 2008, the EEC regulation allow its use in automobiles as dipped-beam headlamps.

 

The advantages of these lights are different and much better in comparison with incandescent light bulbs: for a start, they occupy less space, are brighter, they can last up to 50 times longer and consume up to 10 times less, and that is not all, its chip allows varying its intensity and colour of light. In addition, with the development of organic LED we could even locate illumination on flexible surfaces, such as textiles and clothing.

However, although the widespread use of LED lights was stopped by its high price a few years back: A lamp of 3W, equivalent to a 40W bulb, used to cost costs about 65 Euros the prices have plummeted and prices are being lower every three months or so. Nowadays you can find the prices of LED bulbs could be cheaper than traditional lighting!!

 

For its part, Silicon could also become the light of the future material. A Canadian company, Group IV Semiconductor, ensures to have developed a technology that would make it possible to manufacture 2014 light bulbs which last for 20 years and consume less power than the current 90%. The system consists of passing electricity through a semiconductor of silicon, making almost all of the energy in light.

The use of non-polluting materials is also another of the concerns of the sector, given the toxicity of some light elements. For example, there are estimated only in the European Union (EU) 35 million mercury vapour, highly polluting, lamps installed on streets and highways. Meanwhile, the recycling of these lighting elements in convenient places such as clean spots is a good way to help preserve the environment.

 

The light surplus, in addition to energy expenditure, negatively affects many species of insects, large numbers of migratory birds, birds of prey, or bats. An example to follow in the fight against this problem is the so-called project "Eco light": promoted by the EU and the city of Valencia, its objective is to curb light pollution in the natural park of the Albufera. To do this, they have installed a model of perimeter lighting, with lower streetlights of a casserole type, which focus on the ground more efficiently.

 

All in all, there are no excuses for not installing LED bulbs as they are manufactured using the typical screw bulb type so you just fit it in without having to install new electrical circuits or other paraphernalia.

So do your pocket and the environment a favour and install LED lighting whenever you can.

 

Led Colours.

It is hard to believe that there are those who still do not know the multiple and varied advantages of lighting with LED lights. On the one hand, LED are a ecological way to illuminate for various reasons: reducing energy consumption by up to 80%, which means a saving of resources that is not negligible. Its useful life is much longer than traditional halogen lights, LED can last about 50,000 hours, so we will need to change less frequently.

 

In addition, are less polluting because LED lights do not contain mercury like fluorescent lamps, and are very safe elements that considerably reduce the risk of domestic accidents compared with other lighting technologies. And all without forgetting another great advantage that is the quality of the light, clear and bright.

 

Although fluorescence and incandescent light persists, LED technology is conceived as present and future of the sector. half a century ago that the American scientist Nick Holonyak devised emitting diodes, whose main mission was to save energy. Then with the regulation towards sustainable horizons, Europe began requiring the development of LED technology for its "green" features.

 

 

LED lighting meets all the requirements for converting external areas of your home in a pleasant landscape and visually appealing. The versatility of LED lighting allows you to create effects such as variety of colors, its small size and various light options for its numerous designs. Ideal for walkways or passage areas and signs.

Many LED systems for outdoor lighting have their own solar panels to supply with energy its bulbs. It is an ideal solution because it loads up during the day and automatically turn on when the light begins to fail. We also save on installation wiring which sometimes can be complex and cumbersome. Obviously, it doesn´t consume any electricity and usually last almost all night. This is another advantage to consider because an illuminated garden or terrace usually dissuades thieves and avoids unpleasant surprises. And another thing, a solar powered system of lighting by solar panels will be active even if we are not at home.

LED outdoor lights have the same advantages as indoor LED lights, with the difference that their manufacturing materials are prepared to withstand the conditions of being out in the open. So if our intention is to create a special environment for our outdoor spaces of our home, LED lighting offers us all the possibilities and possible combinations that we can imagine.

 

 

The first thing is to think calmly and study beforehand some examples that can help us to know what kind of lighting we want in our garden or terrace. Some advice is to keep steps and junctions well lit, and balance the rest of external areas.

 

Automat lighting will go in crescendo, providing better lighting solutions. This is an industry that moves much economy, because it is necessary for all the daily aspects of life.

 

 

It is very likely that in a few years we will live an even greater leap in innovation. An environment in which infinite electronic possibilities will be deployed through lighting, and which will allow controlling the flow of purchases with systems such as "heatmapping" (heat maps), regulating the amount of light in an environment through the voice, besides other things that can now be unimaginable. Let there be light!!
