Getting Down To Basics with Lighting

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.

Diodes using DC circuits are used in LED lighting and this emits light that extends battery life and are used for flashlights and other light emitting gadgets like cellphones and other devices. 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. There are many advantages to using LED lighting which can now be run from an AC supply. So before they were only considered to be DC devices operating from a few volts of direct current but now has a more robust application that requires the same amount of voltage such as the 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. 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. 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. Today transformers are used to provide the required DC violated for many stand alone fixtures. 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 upfront costs of these LED lighting are very expensive. Many would argue though that eventually it pays off because your power bill would decrease remarkably.

The early for of LED lights is what is called the Christmas tree light approach. Here multiple LEDs are connected in series so that the voltage drop across the whole string equals 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.
