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. it then included vehicular headlights by using specially designed reflectors, intensifying its brightness and the length of its coverage while 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. 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. 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.
In order to operate your LED lights today, you run your LED lighting from an AC supply which is converted to DC power. 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. 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. However, there are a lot of people who would argue that despite the high upfront cost you would eventually lower your power bill remarkably.
The early for of LED lights is what is called the Christmas tree light approach. This approach uses multiple LEDs 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. The advantages of LED lighting over conventional lighting are so great that it will not only benefit the user but the planet as well.
