Last night, being at a concert, I saw that now ushers use LED Light and started to think how our lives have changed LED technology

What is it, does it work?

LED Light Emitting Diode, as its name says is a semiconductor light emitting diode.
Who does not remember the old 80′s electronic games wearing those red LED barely lit?
Now technology has advanced so much that there is hardly anyone who has not used the technology led at some point.

Whether at home, in your car, on a plane, on your computer, on your watch.
The LED Light are everywhere and are changing the way we literally see the world.
In some cities are changing the traditional incandescent amber lights the streets, leds.
The reason? Are more economical because their energy is low, are more durable with a longer life.

For example, an incandescent light bulb has a lifespan of between 750 and 1000 hrs, led a round focus on average about 25,000 hrs.
An LED bulb consumes about 80% less energy, for the lighting of a bulb of 60watts 12watts consumed.
The LED lights not only are the street lamps, are also being used in cars and even airplanes.

Is common and, finding flashlights and LED desk lamp by a very low price.
But not only are led, there are now revolutionizing television.
What is the difference between an LED TV, plasma or LCD?, What is better?
3 are generally good, but most important before deciding on one in particular is that we know about, some work better “blacks” and are for bright places (LCD), and small formats , (21 ‘to 32′) other work best in dark or closed (plasma) and large format (32 ‘or more), led in large format is excellent and animated films, in addition to their energy consumption is 40% lower than the 2 above, but for now, are the highest cost.
Undoubtedly, the LED Light technology becoming more and more advanced and thus their use.
Soon we will see more applications in daily life.
