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.

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. 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. 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. Applications or options came to do that – converting AC to DC power to run LED lights. In order to provide the required DC voltage, there are many stand alone fixtures that have a transformer between the wall socket and the fixture. 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.

Another early form 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.

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. 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.
