Finding Ways To Keep Up With Options

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.

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 began to find its way to vehicular headlights by utilizing a specially designed reflectors to intensify its brightness and length of coverage but 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. 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. With alternating current of AC, this is not necessary since it is able to maintain the voltage despite the distances. DC power has always had this problems and the reason why they are not being used to transmit power across our streets and cities.

Running LED lighting from an AC supply means producing DC power to operate yo LED lights. And there are several applications for this. 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. 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. 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. 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.
