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.
Diodes using DC circuits are used in LED lighting and this emits light that extends battery life and are used for flashlights and other light emitting gadgets like cellphones and other devices. it then included vehicular headlights by using specially designed reflectors, intensifying its brightness and the length of its coverage while still maintaining its efficiency. Today, it is now possible to run LED lighting from an AC supply that offers several advantages. These used to be DC devices operating from a few volts of direct current but can now be used for more robust applications that require the same amount of voltage like those 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. So then it would require the use of a higher drive voltage once the voltages start to drop and so additional regulators need to be used to maintain the voltage. 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. DC power has always had this problems and the reason why they are 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. 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. These types of LED lighting are very expensive upfront. 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.
