Illumination led, translated to Spanish as a light emitting diode, is a device that emits light colour, i.e. in different waves of amplitude, this happens when it is crossed by the electric current. The fundamental part of the led is a semiconductor, which gives further color to the light emitted. There are electrodes that produce the light beam moving, within the semiconductor. This type of lighting began to use beginning in 1960 at the industry level, although the first led is invented in 1927. In our days we can see the led lights in many urban everyday applications, such as informational panels, liquid crystal displays lighting, cellphones and flashlights, among others.Led lights have some advantages compared with traditional incandescent lamps.
Among them: that they have equal light output than traditional lamps but they do so with one lower consumption of energy. are suitable to decorate the variety of colors that offers both for exteriors as interiors. Its qualities of versatility, durability and fundamentally lower power consumption make it the favorite of decorators. The long service life: some manufacturers estimate a duration of more than 30000 hours of useful life, almost three years. Does not give off heat to be lit unlike lamps incandescent. mercury is not needed to produce it, so this is healthy for the environment care led lighting can be rotating, sequential, or fixed, as opposed to the traditional ones, which are of a single type is useful in difficult to access facilities. has great resistance to shocks.
All the advantages listed above lead to think that the sale of led lightings will increase in the coming years, because manufacturers are interested in producing lower consumption and greater ability to light led lights. All this It is powered by the future energy crisis already Governments are anticipating. He is the development of this technology that helps save resources in the long term and requires no pollutants for its manufacture some future applications would be for traffic lights, displays or posters. It is not yet common, but is now a reality and is one of the most interesting applications of lighting LED in public spaces. It is used in street lighting, in this case the location of LEDs powered by solar panels allow autonomous systems for off and on but with the advantage of zero consumption.
