Learning The Secrets About Lighting

Advantages of LED 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.

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 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. LED lighting can now be run from an AC supply which is very advantageous. 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. Since DC drives suffer power loss over distance it then brings a different consideration. 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. 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.

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. Today transformers are used to provide the required DC violated for many stand alone fixtures. 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. 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. 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.
