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. it then included vehicular headlights by using specially designed reflectors, intensifying its brightness and the length of its coverage while still maintaining its efficiency. There are many advantages to using LED lighting which can now be run from an AC supply. So what once are usually considered to be for DC devices operating from a few volts (of direct current) can now be used for a more robust application that requires the same amount of voltage – like those linear strip-lightning systems around the outside of a building stretching for one 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. This is not necessary if you have AC or alternative current since it main maintain voltage despite 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.
Today running LED lighting from an AC supply means converting your AC supply to produce DC power to operate your LED lights. And several options came to do that. Many stand-alone fixtures simply have a transformer between the wall socket and the fixture to provide the required DC voltage. 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 problem with these types is that its upfront cost are quite costly. Despite the high upfront cost you can expect a remarkable decrease in your power bill in the long run.
The early for of LED lights is what is called the Christmas tree light approach. This approach uses multiple LEDs in series so that the voltage drop across the whole string equals the supply voltage.
There are now attempts at developing true AC LEDs but this will be a big leap in technology that can be seen as an upgrade from analog to digital. This type of lighting have many advantages over conventional lighting and these benefits are so huge and will benefit both the user of technology and out planet.
