Since it is getting more popular all the time because of the enormous energy savings on electricity it seems we are constantly hearing of more and more uses for LED lighting. Manufacturers are always coming out with new uses and that they are helping in a greener future is great. A long lifespan, no distorted tint, energy efficient and a great bonus, does not attract bugs.
People are amazed that in the United States itself 6% of energy consumed is through lighting, but is one of the easier things to cut wasted energy from. In a short 20 year span up to 50% of power could be cut just by converting lights from the conventional incandescent bulbs, fluorescent tubes and halogen to LED lighting.
You probably don't realize it but LED lighting is used in more places and things than you realized. With street lights they are great because they are low maintenance and light direction can be controlled to where it's wanted, not in bedroom windows. LED lighting is used by auto manufacturers for brake lights and Buckingham Palace is experimenting with them in the 60ft. ceiling fixtures.
At this time LED's can only throw light at a very narrow angle in one direction, but all new technology has a few kinks to work out, Presently, to mass produce LED light is difficult because two materials that are not alike are put tightly together making electrons jump from one to another. This procedure is needed because of a tunnel effect causing a need for lenses or reflectors. The quality and lifespan for an inferior product will ruin the longevity of the LED, a reason why to mass produce is so costly.
Europe is one step ahead of the United States as it has been using LED lighting for street lights and commercial buildings. Many places are using President Obama's stimulus towards the installation of LED street lights that will pay for itself in a few years, as they are doing in San Jose, California with plans to install 1,500 street lights with energy savings grants that they have received.
In 2007, LED lighting proved to be a $297 million industry and it is likely that this figure will more than double in the next few years. Scientists and engineers are hard at work to redesign the technique by utilizing silicon instead of precious metals in growing a cheaper variety yet high quality LED light for consumer use. Giants such as General Electric and Philips have seen the potential for a market of growth and are currently testing and making LED's.
Due to unlimited creativity, there are constantly new ways to use LED lighting. In Ann Arbor, Michigan LED's are used as street lights and the city has them programmed to get brighter only when someone approaches or to flicker outside of a home where an emergency is and paramedics have to go. The entire world is striving towards being more energy efficient and LED lighting will be a part of this trend.
