LIGHTING<br />
THE FUTURE OF<br />
WHY LED?<br />
LED light bulbs last<br />
longer/ They are<br />
more durable and<br />
offer comparable or<br />
better light quality<br />
than other types of<br />
Lighting.<br />
Our quest for a green environment and eco-friendly future has<br />
given rise to many innovations. One of the ways to achieve this<br />
noble task is through energy efficiency. The lighting industry is<br />
contributing strongly to the achievement of international targets<br />
for energy efficiency and reduction of greenhouse emissions.<br />
The light – emitting diode (LED) is one of today’s most energy –<br />
efficient and rapidly – developing lighting technologies.<br />
However, success of this technology depends on the widespread<br />
adoption of new lighting methods. The relatively low uptake of<br />
compact - fluorescent lamps offers lessons in how not to change<br />
the market. One important consideration is that the new product<br />
must at least maintain the performance levels of the one it<br />
replaces, and if possible there should be an improvement.<br />
One might ask: Why LED? LED light bulbs last longer. They are<br />
more durable and offer comparable or better light quality than<br />
other types of Lighting. LEDs are semiconductors that reproduce<br />
the current waveform faithfully with a very rapid response, and<br />
the electronics to drive the device vary from one device to another.<br />
LED is a highly energy efficient lighting technology; it has the<br />
potential to fundamentally change the future of Lighting in the<br />
world. LEDs use at least 75% less energy and last 25 times longer,<br />
than incandescent lighting. There’s an excellent reason LEDs have<br />
taken on the aura of inevitability. LEDs are semiconductors; and<br />
like all solid-state technology, they are getting better and cheaper<br />
on predictable curve. By charting the historical prices of LEDs and<br />
projecting forward, Roland Haitz the LED pioneer, estimated that<br />
the amount of light they produce would increase by a factor of 20<br />
per decade, while the cost would correspondingly drop by a factor<br />
of 10. The LED revolution also encompasses light for better health,<br />
year round, as well as contributes to a host of other environmental<br />
benefits.<br />
