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 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. 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. This is not necessary if you have AC or alternative current since it main maintain voltage despite distance. 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. And there are several applications for this. 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. LED light bulbs today can be screwed directly into a standard socket and these contain miniature circuits that convert AC to DC before being delivered 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 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.

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. 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.
