The Essentials of Options – Getting to Point A

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.

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 found its way to headlights of vehicles by using a specially designed reflector to intensify the brightness and length of coverage while maintain 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. With alternating current of AC, this is not necessary since it is able to maintain the voltage despite the distances. This has always been the problem with DC power and it is the reason why we don’t use it to transmit power across our streets and cities.

Running LED lighting from an AC supply means producing DC power to operate yo LED lights. Applications or options came to do that – converting AC to DC power to run LED lights. Today transformers are used to provide the required DC violated for many stand alone fixtures. 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. Many would argue though that eventually it pays off because your power bill would decrease 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.

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.
