What Makes LED Better than Conventional Lighting?

Light emitting diodes or LED lighting must be the best lighting so far since it saves energy and a very smart solution compared to the other methods of illumination that you can find 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. 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. Since DC drives suffer power loss over distance it then brings a different consideration. And in order to maintain the voltage there is now a need to use a higher drive voltage when the voltages start to drop and so additional regulators are needed. 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. 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. 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. Here multiple LEDs are connected in series so that the voltage drop across the whole string equals 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.
