LED simply means ‘light emitting diode’. The diode is simply a small component which lights up when electricity passes through it. Diodes are everywhere, in your TV, Radio, DVD and PC.
LEDs are basically produced by clustering small bulbs. The first clustered bulbs were used for battery powered items such as car headlamps and torch flashlights. Now LED bulbs are made using as many as 150 bulbs per cluster, and encased in different types of lenses which spread the light in wider beams.
The latest generation of LED lighting is now available with standard bases to fit all common household light fittings.
Traditional light bulbs pass electricity through a filament, which results in energy being released as both heat and light, leading to a lot of heat being wasted.
LEDs last much longer than standard bulbs, consume a lot less energy and emit very little heat.
The Government and energy companies are phasing out inefficient light bulbs and manufacturers are producing more energy saving light bulbs to meet the growing demand. In the UK, the European Commission is phasing out inefficient light bulb and all filament bulbs have been banned within the EU by 2016.
