What Makes LED Better than Conventional 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.
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. it then included vehicular headlights by using specially designed reflectors, intensifying its brightness and the length of its coverage while still maintaining its efficiency. There are many advantages to using LED lighting which can now be run from an AC supply. 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. 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.
Today running LED lighting from an AC supply means converting your AC supply to produce DC power to operate your 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. The problem with these types is that its upfront cost are quite costly. 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. And the advantages versus conventional lighting are so huge and of major benefit to both the user of this technology as well as our planet.…
