Public lighting is responsible for valuing the architecture of the city when the sun sets-but it is also responsible for ensuring the safety of citizens, avoiding assaults and accidents in large urban centers.
But it is a fact that spending to light miles in cities is not at all reasonable. In São Paulo, for example, about R $ 97 million reais are earmarked for electricity to lighten the city at night.
However, with the invention of the blue light emitter diode, combined with the green and red LEDs that already existed, white light bulbs were created – they are more durable and efficient than the others.
The municipalities of several cities in Brazil, then, saw in the LED lamps a possibility of saving of expenses, besides guaranteeing an improvement in the service of public illumination. Several capitals and cities in the interior have already approved the exchange of much of the public lighting of sodium vapor lamps for LED bulbs. In other countries of the world the idea has also gained prominence.
In Italy, for example, the company iGuzzini Illuminazione took advantage of Aschilede LED technology for urban lighting – with this innovation, the environment is able to stay clearer and the lamps last longer.
In Mexico, Lightning Science installed LED bulbs on a 23km road in Mexico City and the result was incredible: about 40-50% of the electricity consumed was saved. In addition, the company’s bulbs can be replenished by solar and wind power-helping not only cut costs but also help to improve the city’s landscape.
In addition to providing outstanding cost savings, LED lamps also perform considerably better than sodium vapor lamps.In numbers, LED bulbs are capable of producing 425% brighter than other bulbs. In addition, while incandescent bulbs have a life of 1,000 hours and fluorescents of 10,000 hours, the LED lasts between 30,000 and 100,000 hours.
The LED still collaborates for the well being of the population and for the preservation of the environment – this is because it has no materials harmful to health or nature, such as mercury or lead. In addition, there is no emission of UV rays or elevation of the temperatures of the place.
To save even more energy consumption, the vast majority of cities have already installed the poles with the photocell system. This technology basically consists of sensors that are able to detect when sunlight is no longer sufficient to illuminate the site. Naturally, the sensors are also able to see when the electric light from the pole can be turned off when the sun comes up again.
But LED technology has not only invaded the city streets-domestic environments have also embraced the novelty. A very recurrent way to use LED bulbs at home is in decorative lighting: LED spots are able to direct the illumination and discretely value some of the decor of the environment. They add charm and refinement to any home.
It has been proven that LED bulbs are the best solution to many problems regarding the consumption of electricity: saving of expenses, reduction of consumption, without harming the health or the environment, all with a durability that make the cost benefit of this technology Be incredible.
