What Makes LED Better than Conventional 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.
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. Today, it is now possible to run LED lighting from an AC supply that offers several advantages. These used to be DC devices operating from a few volts of direct current but can now be used for more robust applications that require the same amount of voltage like those 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. 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.
Today running LED lighting from an AC supply means converting your AC supply to produce DC power to operate your LED lights. Applications or options came to do that – converting AC to DC power to run LED lights. 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. 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.
Another early form 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.
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.
