Why No One Talks About Lighting Anymore

What Makes LED Better than Conventional 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.

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 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. 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. 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. 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 the reason why it is not being used 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. Many stand-alone fixtures simply have a transformer between the wall socket and the fixture to provide the required DC voltage. 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. The problem with these types is that its upfront cost are quite costly. 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. 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. This type of lighting have many advantages over conventional lighting and these benefits are so huge and will benefit both the user of technology and out planet.
