Why not learn more about Lights?

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.

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. 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. LED lighting can now be run from an AC supply which is very advantageous. 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. This brings a different consideration because a DC drive suffers 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. This is not necessary if you have AC or alternative current since it main maintain voltage despite distance. This has always been the problem with DC power and the reason why it is 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. And there are several applications for this. Today transformers are used to provide the required DC violated for many stand alone fixtures. 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. This approach uses multiple LEDs in series so that the voltage drop across the whole string equals 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.
