Guide to LED 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. Today, it is now possible to run LED lighting from an AC supply that offers several advantages. 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. 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. 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.

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 however attempts to develop ‘true’ AC-LEDs but right now we have to contend ourselves on this 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.
