Advantages of 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. 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. 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. Applications or options came to do that – converting AC to DC power to run LED lights. In order to provide the required DC voltage, there are many stand alone fixtures that have a transformer between the wall socket and the fixture. And there are a number of companies that provide LED light bulbs that screw directly into standard sockets, but these invariably also contain miniaturized circuitry that converts AC to DC before delivering it to the LEDs. The upfront costs of these LED lighting are very expensive. 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. In this approach multiple LED lights are connected in series so that voltage drop across the whole siring equal the supply voltage.
There are however attempts to develop ‘true’ AC-LEDs but right now we have to contend ourselves on this big leap in technology that can be seen as an upgrade from analog to digital. And the advantages versus conventional lighting are so huge and of major benefit to both the user of this technology as well as our planet.
