There is no denying the fact that the evolution of LED lighting has given birth to more long lasting and more energy efficient sources of lighting when compared to the traditional sources of lighting. But the question is how did the LED lights evolve and what were the various stages of evolution that the LED lights had gone through. In fact, the discovery of the blue LED is around 20 years old but the kind of white light that has been created by this evolution will certainly change the future of the lighting industry as well as our planet. It was between years 2010 and 2014 that LED lighting came into higher focus.
In 1972 M. George Craford for the first time had invented the first yellow LED light and a brighter version of red LED light. In 1979 the first blue LED was invented but till the year 1994 these LED lights was too expensive to be used commercially. However, now the LED lights can be made in multiple colors.
In recent times light emitting diodes have become a preferred choice among households as commercial set up. The reasons are many. First of all they emit more light per watt when compared to the traditional incandescent bulbs, they have a smaller size, and they are quick and can be operated in no time, which means the on/off time is almost negligible. At the same time, they have a longer life and also they are not damaged that easily. But that does not mean that LED lighting has no flaws. There are few problems like they are highly priced per lumen; they have high dependence on the outside temperature. Also they are prone to easy overheating if the outside temperature is too high and also there is no heat sink. But the truth is in spite of the flaws the concept of LED light will stay on for longer and rule the lighting industry.
Possibilities of LED lighting
As far as the future of the LED lighting is concerned it is quite bright and the manufacturers should take full advantage of this situation. As LED lights have the capacity to take on different shapes and sizes they have tremendous potential both for interior as well as exterior lighting solutions. The LED lights can also be integrated into various architectural materials like the concrete.
The possibilities are endless for LED lights because they can operate efficiently both with DC power or AC power and also operating on a low voltage is not a problem with the LED lights. Another added feature of the LED lights is that they can operate on a temperature as low as -40 degrees centigrade. Last but not the least, the fact that they are environment friendly takes them a long way. There is encouragement with the use of LED lights because that reduces your carbon footprint on the planet.
