led bulbs now as bright as 100 watts

Two leading manufacturers of lighting products have shown enough LED bulbs to replace energyguzzling 100-
The Watt lights will disappear from the store on January.
Their demonstrations at this week\'s lantern show in Philadelphia meant that brighter LED bulbs could be introduced next year, but after the government ban came into effect.
New bulbs will be expensive, too. -
About $50 per vehicle-
As a result, this development may not prevent consumers from hoarding traditional bulbs.
The technology of traditional \"incandescent\" bulbs has been more than a century.
Such bulbs waste most of the power they supply and turn them into heat. The 100-
Especially the watt bulb, which produces so much heat that in Hasbro\'s Easy-Bake Oven.
In order to encourage energy efficiency, Congress passed a law in 2007 stipulating that from 2012, production of 100-watt bulbs could meet certain efficiency targets.
Traditional bulbs do not meet these targets, so the manufacture or import of bulbs will be prohibited by law.
The same rule will be applied to the remaining 40 W and above bulbs starting on 2014.
Since January, California has banned stores from buying another 100-
Incandescent lamps in Watt.
Good alternatives to creating bulbs are much more difficult than expected, especially for very bright 100-watt bulbs.
Part of the problem is that these new bulbs must be installed in fixtures and ceiling fixtures designed for old technology.
Compact fluorescent lamps are the most obvious alternatives, but there are also disadvantages.
They contain a small amount of toxic mercury vapor that is released if they break or are improperly discarded.
They last longer than conventional bulbs, but not more than LEDs.
The brighter model is large in size and may not be suitable for existing fixtures.
Another new lighting technology, organic light
LEDs (oled) have encountered problems in mass production.
Oled is a light-emitting sheet or tile, not a needle-tied light source like an led.
They are used as color screens for smartphones, especially for Samsung Electronics.
But make big, bright, cheap, long oled-
It turns out that it is difficult to use long enough as a light source, in part because they use oxygen-sensitive chemicals that can be damaged unless they are sealed with great care.

The company will display some OLED panels at the exhibition.
They will be available for sale next year, but prices may make them a technology showcase rather than a candidate for everyday lighting.
LEDs are efficient, durable and produced in large quantities, but they are still expensive.
A led bulb can hold more than a dozen lights
LEDs or small semiconductor chips cost about $1 each.
The biggest problem with LEDs is that although they produce less heat than incandescent lamps, the heat they produce shortens the life and reduces the efficiency of the chip.

The shape packaging suitable for today\'s lamps and sockets makes the heat problem worse.
The brighter the bulb, the bigger the problem.

Produce light equivalent to 60-
Watt bulbs, though with more powerful directional or floodlit lighting.
Osram sivania of Siemens, Germany, says it has overcome the heat problem and will show a pearshaped 100-watt-
This week\'s LED bulbs are comparable.
It doesn\'t have a definite listing date, but it\'s usually displayed about a year before the product goes public.

A company specializing in LED lighting will showcase a few 100-watt-
Similar prototypes include prototypes that solve led cooling problems by using micro-devices (such as micro-fans) that move air on the chip. Before the 100-
Waters, there will be 75-
The shelves are filled with water this year.
Osram sivania will sell them at Lao from July.
Royal Philips Electronics, the world\'s largest lighting maker, will put them in stores at $40 to $45 by the end of this year. However, 60-
Watt bulbs are the biggest awards because they are the most common.

Today, Zia Eftekhar, head of Philips North American lighting department, said.
Replace the energy savings they can achieve with 10-
The watt LED bulb is shocking.
To stimulate the development of LED, the federal government has set up a $10 million energy \"L Award\"
Efficient replacement of 60-watt bulb.
Philips is the only contestant in the test so far, and Eftekhar expects the company to win the test soon.
But the Lighting Science Group plans to enter itself and it will show this at the trade show.
Philips has been selling 60-watt-
Since December, Home Depot\'s equivalent bulbs are very similar to those submitted for the competition.
But it\'s a little bit darker, with a power consumption of 2 watts and a cost of $40, while the L-Prize target is $22.
Sylvania also sells a similar LED bulb at Lowe\'s for $40.
However, LED prices are falling rapidly.
DOE expects 60-
By 2015, watt\'s equivalent to LED bulbs will cost $10, making them within the price range of compact fluorescent bulbs.
Bob Karlicek, director, intelligent lighting research center, Troy rensler Institute of Technology, New YorkY.
Think that the price can be realized.
But, he said, \"it\'s not necessarily clear to people in the lighting industry that LED chips once intended to enter the bulb.
\"What is really needed, he said, is a new way of lighting ---
New fixtures and lamps can disperse LEDs, avoiding heat problems.
