Advantages of LED Lighting
LED lighting or light emitting diodes is by far the most energy-saving and a smart solution when you compare it with those other methods of illumination 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. 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. 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. 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. And several options came to do that. 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. These types of LED lighting are very expensive upfront. 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 Christmas tree light approach was an early for of this type of lighting. 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.
