The light-emitting diode (LED) is truly a revolutionary and persistent child of technology. It is cheaper than its incandescent and florescent counterparts, several times brilliant, more efficient in energy consumption and has longer life span. This simply means brighter rooms on cheaper electric bills.
Originally, LED lights were used primarily for industrial purposes. Its first large-scale application was the lighting of factory interiors and exteriors in the U.S. and India in 2008. Although cost of the LED bulbs was thrice its traditional commercial counterpart at the time, expenses were easily recovered within two to three years. Results were more than encouraging such that in just a few years, larger companies, particularly, information-technology (IT) firms shifted to using LED bulbs to light significantly larger areas of up to 60,000 sq. ft.
A few years further still, the LED lamp was used in public areas such as the landmark lighting of the Christmas tree in Turku Cathedral in 2009 where 710 LED lamps. Soon, other major public infrastructures like highways were operated with LED bulbs as lighting utility. In just barely three years, the LED hit mass consumer markets and succeeded in staggering consumption rates as smaller offices and even households turned to it as primary lighting source.
Today, with its blinding pace of its development and even more rapid commercial success, LED technology is being applied to an ever-expanding array of LED-based products from television to cellular gadgets. It has found its way into the design of LED displays, a flat panel display which used LED lights or pixels for video display. The technology is now a standard feature of television screens and cellular phones worldwide and is in fact dominating its traditional competitors such as plasma screen.
And it seems LED technology isn’t done yet as more innovations are expected to further impose the dominance of LED in the market. These products are now widely available in major commercial markets specifically in China and Singapore.
In the industry, round wall washers or utility lights that can emit as much as 2000 lumens to a distance of 56 feet has just broken the market for security lighting last year. New wet-location bulbs like the PAR20-38 are quickly replacing halogen lamps for safety and rescue operations. There are now LED light tiles which is expected to replace traditional tiles in no time as this product offers a convenient option to conventional tiles without the hassle of separate electrical wiring installations. Architectural and water-grade LED pucks and omni-directional light bulbs that operate at 100W is also now a viable option for lighting considerably wide open spaces.
For home use, the development of remote control dimmers, LED step lights, LED accent lights are new products that could make the incandescent and florescent lamps irrelevant for domestic indoor use. For outdoor activities, rechargeable battery packs, solar panels and a host of technologies have given the led more competitive advantage due to numerous possible power sources compared to traditional lights. Water-submersible and flexible strip lights also provide flexibility and uses that were unimaginable with the dominant light products of the past.
As newer bolder LED products are steadily spawned from a seemingly inexhaustible assembly line, it is perhaps safe to say that only one thing can be expected from the LED industry: infinite possibilities.
