The Art of Mastering Lighting

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.

In LED lighting, diodes are used using DC circuits to emit light that extends battery life that is used for flashlights and other light emitting gadgets like cellphones, and other. Then it found its way to headlights of vehicles by using a specially designed reflector to intensify the brightness and length of coverage while maintain 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. There are different considerations that is brought in since DC drives suffer power loss over distance. 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. Something you do not need to do with an AC or the character of an ‘Alternating Current’ since it can maintain the voltage despite the 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.

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. The upfront costs of these LED lighting are very expensive. Despite the high upfront cost you can expect a remarkable decrease in your power bill in the long run.

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.

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. 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.
