Advantages of LED Lighting
Light emitting diodes or LED lighting must be the best lighting so far since it saves energy and a very smart solution compared to the other methods of illumination that you can find in the market today.
It started out by utilizing these diodes via a DC circuit to emit light to extend the battery life that is used for flashlights and other light emitting gadgets like cellphones and etc. 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. 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. There are different considerations that is brought in since DC drives suffer 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. 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. Many stand-alone fixtures simply have a transformer between the wall socket and the fixture to provide the required DC voltage. 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. 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 Christmas tree light approach was an early for of this type of lighting. 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. The advantages of LED lighting over conventional lighting are so great that it will not only benefit the user but the planet as well.
