Guide to LED lighting
Today, light emitting diodes or LED lighting is the best when it come to energy saving and a smart solution compared to other methods of lighting 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. 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. Since DC drives suffer power loss over distance it then brings a different consideration. 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. This is not necessary if you have AC or alternative current since it main maintain voltage despite 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.
Running LED lighting from an AC supply means producing DC power to operate yo 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. 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. Many would argue though that eventually it pays off because your power bill would decrease remarkably.
The Christmas tree light approach was an early for of this type of lighting. 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. The advantages of LED lighting over conventional lighting are so great that it will not only benefit the user but the planet as well.
