leds: lighting the way to major energy savings
In his State of the Union address on Tuesday night, President Obama put forward his ambitious goal of reducing energy consumption: \"Let\'s cut our energy by half in the next 20 years and waste it on our families and businesses.
Why wait so long?
Technology and the economy to achieve that goal exist today.
Now one of the oldest devices to waste power in your home is the lights you use when reading this.
Your incandescent lamp is based on more than 130 years of technology, a light source that converts most of the energy of the bulb into heat rather than light.
US company based on modern technology manufacturing lighting-led (
Consumers can save money and cut lighting power by up to 80%. Today.
This change can achieve most of the president\'s goals, as lighting accounts for nearly onefifth (19 percent)
According to U. S. data, average household electricity consumptionS.

As consumers, we have used LED lights in our phones and HD TVs.
The barrier that high efficiency LEDs are widely used for lighting is the high upfront cost of LED lamps and bulbs.
But now the advances in technology have dramatically reduced the price so that LED bulbs below $10 will soon become a reality, and it can provide excellent, high-quality lights for more than ten years.
For businesses and municipalities, LED lighting has been very well calculated.
The city of Los Angeles saved $5.
£ 3 million per year due to the Green LA initiative, which has so far replaced £ 114,000
Pressure Sodium street lamps with LED lighting, the largest such project in the United States.
Once completed, Los Angeles expects LED lighting to save taxpayers $10million-a-
Nearly two years.
This is the price the city has paid to illuminate the streets.
Convenience store and gas station chain Sheetz, ranked 61 on Forbes magazine\'s list of the largest private companies in the United States, has installed LED interior and exterior lighting in more than 130 locations in six states.
Energy saving: internal lighting 45%, external lighting 55%, lighting the air pump of Sheetz.
LED lighting helps to improve top-as the cost goes down-
According to Sheetz\'s report, the production line grew and customers found brighter facilities more visually attractive and thought they were safer.
These examples explain why led accounts for 8% of the US. S.
According to McKinsey, the lighting market in 2012
It is mainly in street lighting, retail and office environment.
Now it\'s the consumer\'s turn.
Fundamental advances in LED semiconductor technology, optics, and lighting system design now enable LED lights to break through centuries-old cost and performance barriers that prevent consumers from achieving the savings businesses and municipalities they already enjoy.
While typical incandescent lamps use a power of 60 watts to glow, the current state of LED technology can produce the same light in less than 10 watts.
Better and more efficient products mean cheaper lights.
For consumers, this means saving a lot of money.
With the reduction of cost factors, the adoption of LED lighting is also climbing.
Current cost reductions in the industry could double the amount of LED lighting used next year.
The shorter the return on upfront spending, the more likely consumers will be to choose LED lighting.
We have seen this trend in the commercial lighting market.
As we approach price parity with traditional lighting, any remaining barriers to commercial and consumer adoption should continue to decrease and we believe adoption rates will accelerate.
This trend not only brings better lighting, but also saves money and time for Americans (
Imagine not changing bulbs for more than ten years)
But it will also eliminate a lot of physical waste.
Overall, 5, according to IMS Research.
Families and businesses in the United States have 6 billion light bulbs, including 4.
2 billion incandescent lamps and about 1 billion compact fluorescent bulbs (CFL)
Bulbs containing toxic mercury.
More than 1 billion new bulbs are purchased each year.
