Guide to LED lighting
Today, light emitting diodes or LED lighting is the best when it come to energy saving and a smart solution compared to other methods of lighting available in the market today.
In LED lighting, diodes are used using DC circuits to emit light that extends battery life that is used for flashlights and other light emitting gadgets like cellphones, and other. Then it began to find its way to vehicular headlights by utilizing a specially designed reflectors to intensify its brightness and length of coverage but still maintaining its efficiency. There are many advantages to using LED lighting which can now be run from an AC supply. So before they were only considered to be DC devices operating from a few volts of direct current but now has a more robust application that requires the same amount of voltage such as the linear strip lighting systems around the outside of a building that stretches for a hundred meters. This brings a different consideration because a DC drive suffers power loss over distance. And in order to maintain the voltage there is now a need to use a higher drive voltage when the voltages start to drop and so additional regulators are needed. Something you do not need to do with an AC or the character of an ‘Alternating Current’ since it can maintain the voltage despite the distance. This has always been the problem with DC power and the reason why it is not being used to transmit power across our streets and cities.
In order to operate your LED lights today, you run your LED lighting from an AC supply which is converted to DC power. And several options came to do that. Today transformers are used to provide the required DC violated for many stand alone fixtures. Today, there are companies that provide LED light bulbs that screw directly into standard sockets, but they contain miniature circuits that convert AC to DC before it is delivered to the LEDs. The upfront costs of these LED lighting are very expensive. However, there are a lot of people who would argue that despite the high upfront cost you would eventually lower your power bill remarkably.
The Christmas tree light approach was an early for of this type of lighting. Here multiple LEDs are connected in series so that the voltage drop across the whole string equals the supply voltage.
Attempts at developing true AC LED are beginning but today we still have to wait for this big technological leap that is seen as an upgrade from analog to digital. The advantages of LED lighting over conventional lighting are so great that it will not only benefit the user but the planet as well.
