Guide to 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 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. 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. 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. DC power has always had this problems and the reason why they are not being used to transmit power across our streets and cities.
In order to operate your LED lights today, you run your LED lighting from an AC supply which is converted to DC power. And several options came to do that. Many stand-alone fixtures simply have a transformer between the wall socket and the fixture to provide the required DC voltage. And there are a number of companies that provide LED light bulbs that screw directly into standard sockets, but these invariably also contain miniaturized circuitry that converts AC to DC before delivering it to the LEDs. The problem with these types is that its upfront cost are quite costly. 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. 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.
