What Makes LED Better than Conventional 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. 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. LED lighting can now be run from an AC supply which is very advantageous. 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. Since DC drives suffer power loss over distance it then brings a different consideration. This means that it would now require the use of higher drive voltage from its starting point then once the voltages starts to drop, you will then have to use additional regulators to maintain that voltage. 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 the reason why it is not being used 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. 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 upfront costs of these LED lighting are very expensive. Many would argue though that eventually it pays off because your power bill would decrease remarkably.

The early for of LED lights is what is called the Christmas tree light approach. Here multiple LEDs are connected in series so that the voltage drop across the whole string equals the supply voltage.

Attempts at developing true AC LED are beginning but today we still have to wait for this big technological leap that is 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.
