They have ruled your driving, saved your life countless times, and that little red man made you wait around till you were able to cross the street. That's right - the red, yellow and green on the traffic lights are Led lights right in front of your nose. In fact, Light Emitting Diodes have been around for some time, conceptualized in 1907. However, it wasn't until the 1960s that practical applications were found and LED's were first manufactured. led lighting used to be used exclusively for traffic signals, brake lights and headlights on luxury cars, and indicator lights on appliances. You probably didn't even know that LED lights were lighting up your digital clocks, flashlights and telling you when you've got a new voicemail message on your cell phone. Expensive at the start, as applications grew, benefits were discovered and manufacturing costs went down. According to the American Lighting Association (ALA), lighting manufacturers have invested considerable time, effort and research into adapting this super energy-efficient technology for household use.
LED will lead and light up the future. The light bulb that has lit up our homes since the 1800s is officially on its way out. The inefficient incandescent, has fallen out of favor with the financially and ecologically concerned; starting in 2012, U.S. residents won't be able to buy one even if they want to [source: Linden. The government is taking the little energy suckers off the market."This year 2010, will be the first year where LED's will explode in the residential marketplace," says architect Joe Rey-Barreau, education consultant for the ALA and an associate professor at the University of Kentucky's School of Interior Design. "We are already seeing amazing LED developments in all parts of our lives, from Christmas lights to LED TVs. One area where LED's will become predominant in 2010 is the category of desk and task lamps," Rey-Barreau says. "Another major development will be in replacement bulbs, as the extreme long life of an led light bulbs makes it ideal for replacing recessed lights in hard-to-reach areas such as vaulted ceilings in living rooms or kitchens". If you aren't sure yet if you want to devote a large portion of your living space to the technology, Rey-Barreau suggests trying under-cabinet lighting in the kitchen, a desk or task lamp or path lighting outside to see if you like the illumination it provides before investing in an entire ceiling of recessed fixtures or a large chandelier.
