PWM LED dimming switches on and off at a high speed. The effective if the average is based on the SI time when the LED is on and when off. By using the method PWM LED dimming, on / off frequency must be faster than the human eye can detect to avoid visible flicker. PWM frequency of 200 Hz or higher usually avoid flicker problems. Many PWM current conductors have a specialized LED PWM dimming pin that supports a wide range of frequencies and amplitudes PWM, allowing a simple interface to the external control logic. Often these chips dimming LED driver offers several ways to mitigate an LED.
For example, the LED driver LM3409 from National Semiconductor provides several ways of IF modular LED through PWM techniques. Many vendors, including Allegro Microsystems, Analog Devices, Linear Technology and offer drivers LED PWN National Semiconductor.

Innovative Wearable LED screen
Kickstarter is home to many innovative projects , and one that recently appeared on the site is Fos , LED display system laptop via Bluetooth . Display screens, even small flexible that can be used , are nothing new , but this could be the most innovative solution we've seen so far, with many features that allow this unit Fos to show many items that are related with outdoor activities such as walking , running, or anything else you might want to display for others to see .
Fos is a series of LED lights to show a message on a flexible surface . The screen itself is attached to a piece of fabric that can be connected to your body or clothes in different ways. You can put it in your backpack, on your wrist , belt or jacket . The project aims to multiple versions will come , and of different sizes. You can get one that is 11 inches by 3 inches and is intended for people who want an outdoor LED display , sleeve, or you could get triple Fos belt width , meant to be worn at the waist and will show a warning pattern when you're out in the dark, or even a signal back to show how the bicycle is
to go.
Fos come with a full API so you can use your phone to control what appears on the screen , but by default , you can expect simple things like the distance traveled , current operating objectives , and current heart rate . At this time , there are only 20 days for the financing happen, and have received $ 20,000 of a goal of $ 200,000. It's too early to say whether the team behind this new invention will obtain the funds they need , but if you want to help, check out the various incentives still available . This may well be the most flexible portable LED screen so far.

The future of light is LED
Brett Sharenow chairs the Pepsi Challenge of lightbulbs. The CFO of Switch, a new company in Silicon Valley, Sharenow has put himself in a cabin 20 by 20 in the rear of the Pennsylvania Convention Center in Philadelphia, and he's asking passersby to get two tones identical white. Behind lies a standard incandescent bulb, household lighting technology that has gone largely unchanged since Thomas Edison invented 132 years ago. Behind the other is an impressive prototype, quasi-art deco-style that contains 10 LEDs and a fluid secret. It is a liquid-cooled bulb, as radically different from Edison's invention as anything that has ever been screwed into a standard socket and hopes Sharenow, the next big thing in the lighting industry $ 30 billion. The challenge: Can you tell which is which?
It's the first day of Lightfair, the annual international trade all that glitters, dazzles, blinks or shines, 500 exhibitors and 24,000 visitors who hung row upon row of light after light.

This is the last before Lightfair new regulations governing lightbulb efficiency begin to take effect in the U.S. in January, and there is a real sense of history and urgency in the exhibition hall. Ready or not, the way we light our homes and offices is about to change, and the way technology is in this room somewhere.
If all goes to plan, the provisions of the Law on Energy Independence and Security 2007 effectively prohibit 100-watt incandescent bulbs from 2012. Bulbs will seventy five watts in 2013, followed by 60 - and 40-watt bulbs a year later. So the race to find a suitable replacement technology is coming to the last moment. The industry is betting on LED lighting as the way forward, and is virtually the only bulb technology on LED display: There is hardly a single incandescent or compact fluorescent sick to be seen. Only 200 thousand square meters of companies compete to fill their quota of billions in the world-standard plugs and betting on LEDs as the way to go.
There is an excellent reason LEDs have taken on the aura of inevitability: LEDs are semiconductors, and like all solid state technology, which are getting better and cheaper on a predictable curve. In 1999, a researcher named Roland Haitz, then head semiconductor R & D at Hewlett-Packard, co-author of an article that became the manifesto of the lighting industry. In tracing the historical prices of LEDs and projecting future Haitz estimated that the amount of light they produce has increased by a factor of 20 per decade, while the cost will be proportionately reduced by a factor of 10.
Haitz law has proved remarkably accurate. But the lighting industry still has big hurdles to clear before LEDs gain acceptance by consumers. Beyond the very real problems cooling technique, the costs, the color-light is not persistent public dislike of CFLs, which failed miserably in its intended role as a bulb of the future. That feeling has introduced a fuel Tea Party backlash against the new rules, and there have been attempts in Congress to roll back completely.
The reasoning behind the lighting of the Law on Energy Security and Independence is quite simple: incandescent convert less than 10 percent of the energy pumped into them into light, losing the rest as heat. More efficient bulbs could save billions of dollars, reduce dependence on foreign oil and significantly reduce greenhouse gases.
However, the reaction of consumers resonates, not just CFLs are horrible, flickery, ugly and unreliable. Evolutionary biologists believe that human lighting preferences are the result of our trichromatic vision in non-primate-rare, which makes us especially suited for daylight and color vision primary. There is an anthropological component as well: for 400,000 years, mankind has been banishing darkness with fire. And Edison bulb is, in its essence a burning filament that casts the glow of a flame. Abandoning incandescent bulbs means abandoning fire as our primary source of light for the first time in human history.
As with all exhibitions, business and Lightfair cabins become progressively smaller and the further back patchwork. The front of the hall is the province of the three major industry-Philips, Osram Sylvania and General Electric, founded by Edison himself. Giants give way to a second plane occupied by the likes of Toshiba, Samsung, Leviton and Honeywell. Behind them, small business manufacturers such as LED lighting manufacturers and LED Display manufacturers of accessories, component vendors and Asia-fill the remaining space, to the wall. Here, within smelling distance of the hot dog stand, Sharenow chairs the switch position.
"What's what?" Asks Sharenow. Most people get it wrong, which is significant. When you select what they feel is the top light, that they are selecting the switch.
Although there are a number of 60 Watt LED Lightfair testing prototypes, few are available for side-by-side comparisons with incandescents. Most are sealed inside cabinets or exist only press releases or PowerPoint presentations. The bulbs are in the open switch: shell crystal clear faceted crystal with aluminum tips holding yellow-tinted LEDs shine through coolant to cast a warm glow salon-quality and draw only 13 watts to do it .
About 80 percent of all bulbs sold in the U.S. or equivalent is calculated at 60, 75 or 100 watts, but almost all LED launched so far has come in the range of 40-watt-equivalent, good for little beyond closets and crawl spaces. Brightest bulbs are too hot, too expensive (more than $ 50, although they can last for 20 years), or both. Change plans to start selling its 60-watt equivalent bulb this fall for about $ 30.
"Light is something that people have always needed," says Sharenow. "It is a light source people want."

Hazle way to close for two months
A section of Hollywood Boulevard in Hazle Township closed for nearly two months from Wednesday to make improvements to the Airport Beltway project .
Mike Bernetski , the Department of Transportation construction manager for the Pennsylvania bypass project , said that the road is supposed to be closed from the ring road to the Fe Drive for 70 days , which would be until early November.
But Bernetski not think the road will be closed so long.
" We've done some of the work drain ," said Bernetski . "We're starting the containment (today) . Such work is included within 70 days, so I think that the road will be made before the 70 days are up. "
The teams have built a road connecting Fe Drive - where is the faith of the United Church of Christ - to connect with Moisey Drive, the road is a traffic signal in front of Walmart , and leads to wellness center Greater Hazleton Health Alliance.
Electronic variable message signs along the bypass road advise drivers will be closed on Wednesday .
" The rest of Hollywood Boulevard will remain open ," said Bernetski . "Companies continue to have access to the connector ring (road) we have built."
The Airport Beltway project involves widening of the 43 -year-old , the road to accommodate a turn lane , an additional lane on the ramp to State Route 93 , a new traffic signal at the intersection in Hazle Township Boulevard, and an update of the road and traffic signal near the Laurel mall .
" The third lane will be more or less go to the length of the road," said Bernetski . "This year , we made two box culverts , and have a lot of ways to do. 're Going to do the drainage work on the north side of the road this year , and on the south side of the road next year . us ' we've done a lot of drainage work on the south side . going to do some paving this year , but it will be the base or bonding layers . we are not going to make the final pavement until next year " .
Bernetski said crews built a "weave" for traffic to cross from the westbound lane of the highway. One lane in each direction has been established on the south side of the road this year .
"We tried to make it as easy as possible for people to use the road," said Bernetski .
From the Laurel Mall Route 93 , the road is already four lanes , but the access ramp to Route 93 to go north, or toward Interstate 81 , will change - the reason that the have shaving equipment down the edge of the Penn State University campus .
" From the mall to 93 will only resurfaced ," said Bernetski . "We are adding a second lane to the entrance ramp from Route 93 and the ramp to the ring to have a longer way of stacking . "
The project, which began in March , is scheduled for completion in November 2014 . The project was necessary because the number of fatal rear along two-lane road , as it was built in 1970. Many new businesses have been built along the road during its existence , including the Laurel Mall and Walmart.

Lights out of jams on Highway 4 Brentwood Sand Creek Road
BRENTWOOD - Far East Contra Costa travelers may actually have something to look forward to Monday.
Friday was the last day of the week that eastbound drivers would be stuck at the light onto Sand Creek Road and Highway 4, which has caused stagnation for years.
The finishing touches were made Friday to the transfer of traffic on the new highway lanes so as of Saturday morning, a highway bridge cross the road and drivers can use offramps to exit the sandy cove.
Overlooking a line of traffic on Highway 4 that extends more than a mile north of Lone Tree Way, local political leaders and transportation officials gathered at the new bridge Friday afternoon to celebrate what they called a "milestone "in the $ 37
million project.
"I'm jacked. This is a big problem, not only for Brentwood, but for the entire eastern Contra Costa County," said Brentwood Mayor Bob Taylor. "It will serve the drivers of a much wider area and really open things up."
Stagnation backed drivers often thousands, especially during the evening rush hour, leaving them two blocks from home, but have to wait 15-20 minutes to make a left turn, he said.
"This provides a great value and improves the quality of life of many people, to get home to their families," said county Supervisor Mary Nejedly Piepho, of Discovery Bay.
Taylor added: "Instead of going in May (mph), drivers can go to 55."
The two-lane road has also caused security problems.
State Assemblywoman Joan Buchanan, D-San Ramon, said his office had "numerous" cuts of accidents on the road, while his district director, Iris Obregon, afraid to let their daughters drive that road at night.
"This will not only help people at home, but it is much safer," he said.
Engineers at Friday's event, said the project contractor would be the addition of the "finishing touches" to the switch overnight, including the addition of rail safety barrier, striping and road and traffic sign placement in Sand Creek.
When completed by the end of next year, Highway 4 have ramps and offramps at Sand Creek and Lone Tree four lanes south of Sand Creek.
A switch alignment of total traffic, which would include moving westward Traffic Highway 4 traffic variable message sign is planned for late October.
Authorities recently shuffled money around to add the construction of a second bridge underpass in Sand Creek, allowing the point of the highway where traffic funnels four lanes to two and move around a mile south, near San Jose Avenue.
Work is underway to incorporate the second bridge project in the project.
Friday was the last day of the week that eastbound drivers would be stuck at the light onto Sand Creek Road and Highway 4, which has caused stagnation for years.
The finishing touches were made Friday to the transfer of traffic on the new highway lanes so as of Saturday morning, a highway bridge cross the road and drivers can use offramps to exit the sandy cove.
Overlooking a line of traffic on Highway 4 that extends more than a mile north of Lone Tree Way, local political leaders and transportation officials gathered at the new bridge Friday afternoon to celebrate what they called a "milestone "in the $ 37
million project.
"I'm jacked. This is a big problem, not only for Brentwood, but for the entire eastern Contra Costa County," said Brentwood Mayor Bob Taylor. "It will serve the drivers of a much wider area and really open things up."
Stagnation backed drivers often thousands, especially during the evening rush hour, leaving them two blocks from home, but have to wait 15-20 minutes to make a left turn, he said.
"This provides a great value and improves the quality of life of many people, to get home to their families," said county Supervisor Mary Nejedly Piepho, of Discovery Bay.
Taylor added: "Instead of going in May (mph), drivers can go to 55."

Researchers are working to bring cheaper, more "green" LED lighting market
Hi everyone！Today we are talking about the "green" LED lighting market.
It's not easy being green. For home lighting applications, organic light emitting diodes (OLED) hold the promise of being both versatile environment. Although not as regular as efficient light-emitting diodes (LEDs), which offer a wider range of equipment options and are more efficient than traditional energy lights. OLEDs can also be flexibly applied to the surfaces, which can lead to the lights or television screens that can be rolled up and stowed in a pocket. One promising line of research involves the combination of OLEDs with inorganic quantum dots tiny semiconductor variable message sign crystals that emit different colors of light depending on their size. These "hybrid" OLED, also called LEDs quantum dot (QD-LEDs), increase the efficiency of light emitting devices and also increase the range of colors that can be produced. Commercially But this promising green manufacturing technology remains difficult and costly. To make OLEDs cheaper and easier, researchers at the University of Louisville in Kentucky are developing the development of new materials and production methods using modified quantum dots and inkjet printing. Delaina According to Amos, a professor at the University of Louisville and the principal investigator of the team's efforts, the cost of materials and manufacturing processes has been a major obstacle to the use of OLED lighting devices daily. Economically implementing their quantum dots hybrid devices, researchers use Louisville inkjet printing, popular in recent years as a way to spray the quantum dots and the OLED materials on a surface with high accuracy. Unlike other groups that experience But with this method, Amos team has focused on the technical adaptation of inkjet printing for use in a commercial environment in which minimizes the cost of mass production and results in products off-the-shelf affordable. "We are currently working on a small scale, typically 1 inch by 1 inch for OLED," said Amos. "The process can be scaled from here, probably 6 inches by 6 inches and larger." "There is a reason we do not see OLED lights for sale in the hardware store," said Amos, but adds that find use in small devices such as LED Display cameras, photo frames, and mobile phone screens. To take your QD-LEDs closer to becoming market-ready devices such as home lighting, Amos and his team have been synthesizing new, less expensive and more environmentally quantum dots. The equipment has been modified also interfaces between the quantum dots and other layers of the OLED display to improve the efficiency with which electrons are transferred, ie enabling them to produce more efficient light in the visible spectrum. In addition to its greater efficiency, greater variety of colors, and abitur to be applied to soft surfaces, Amos' QD-LEDs also use low-toxic materials, making them potentially better for the environment. "Ultimately we want to have low cost, low toxicity, and the ability to make soft devices," says Amos. The team recently demonstrated small devices work, and Amos adds that he hopes to have larger devices in the coming months.

LED traffic lights can not melt snow, ice
LED traffic lights can not melt snow, ice
 |
| Road and Traffic Sign |
- Installation of traffic lights with LED light bulbs save municipalities money, but can also create a hazard for drivers because sometimes lights can not melt snow and ice that accumulate during inclement weather.
- LED bulbs use 90% less energy than incandescent bulbs, and states like Wisconsin have seen savings of $ 750,000 per year. While incandescent bulbs must be replaced every 12 to 18 months, the LEDs installed seven years ago is still going strong, according to the Wisconsin Department of Transportation.
- Then we encounter situations in Illinois last April when 34-year-old Lisa Richter made a left turn and was hit by a driver coming the other way because the ice and snow obscure the light. Winter storms that cover the LED traffic lights have been blamed for dozens of accidents, as they have become more common in the last 10 years.
- At this point, the only solution of the state authorities is to send teams of the city, with air compressors to blow snow and ice off the lights dimmed (which kind of negates the money saving LED lights). Other states have begun to try other solutions like installing weather shields or adding heating elements like those used for airport runway lights.
- While waiting for a technological solution, however, drivers should try the lights dimmed in the same way they would broken traffic signal: Proceed with caution.

The Science of LED bulbs
The Science of LED bulbs

LEDs should light the way to a greener future: They use 75 percent less energy and last 25 times longer than incandescent bulbs, and they do a cooler temperature. But right now, we all use LEDs in electronics, as they have a bit of a problem fallen: at higher currents, the amount of light they produce takes a nosedive.
The drop efficiency has puzzled scientists for years, but researchers at the University of California, Santa Barbara and the French Ecole Polytechnique say they have finally solved the mystery.

LED lights contain a microchip with a positive-type and negative type semiconductor made of gallium nitride. Between the two, in a quantum well, the negative electrons of a semiconductor and electron holes combine the other, producing a photon of light. When more electricity is applied, produces more photons - to a point.

Droop City: As the current increases, the efficiency of the blue LED starts to decline. Y. B. Tao et al. Phys. Status Solidi C, March 2012
In low power, such as your cell phone, the process works very well. But when the current rises to the level needed to illuminate a room, the nitride-based LED stop producing photons in the same proportion. According to research from UCSB Center for energy efficient materials, it is because the electrons collide and lose their energy through heat rather than light.

But it costs more upfront, so until LED technology can live up to its theoretical efficiency at higher currents, it is difficult to sell. While the U.S. already making energy sucking incandescent bulbs, LEDs are still controlling the market for commercial and residential lighting.
So far, we have a solution to the fall, but now we have identified the source of the problem, the researchers hope to design LEDs that minimizes the effect and produce more light, making the technology a more attractive option for home and lighting office.And the application of LED Display is also become more and more popular.

Hello,world.
Let's continue.I will talk about that why led light will be emitted by diode when running through current.
A semiconductor with extra electrons is called N-type material, since it has extra negatively charged particles. In N-type material, free electrons move
from a negatively charged area to a positively charged area.
A semiconductor with extra holes is called P-type material, since it effectively has extra positively charged particles. Electrons can jump from hole to
hole, moving from a negatively charged area to a positively charged area. As a result, the holes themselves appear to move from a positively charged area to
a negatively charged area.
A diode consists of a section of N-type material bonded to a section of P-type material, with electrodes on each end. This arrangement conducts electricity
in only one direction. When no voltage is applied to the diode, electrons from the N-type material fill holes from the P-type material along the junction
between the layers, forming a depletion zone. In a depletion zone, the semiconductor material is returned to its original insulating state -- all of the
holes are filled, so there are no free electrons or empty spaces for electrons, and charge can't flow.
To get rid of the depletion zone, you have to get electrons moving from the N-type area to the P-type area and holes moving in the reverse direction. To do
this, you connect the N-type side of the diode to the negative end of a circuit and the P-type side to the positive end. The free electrons in the N-type
material are repelled by the negative electrode and drawn to the positive electrode. The holes in the P-type material move the other way. When the voltage difference between the electrodes is high enough, the electrons in the depletion zone are boosted out of their holes and begin moving freely again. The depletion zone disappears, and charge moves across the diode.
If you try to run current the other way, with the P-type side connected to the negative end of the circuit and the N-type side connected to the positive
end, current will not flow. The negative electrons in the N-type material are attracted to the positive electrode. The positive holes in the P-type material
are attracted to the negative electrode. No current flows across the junction because the holes and the electrons are each moving in the wrong direction.
The depletion zone increases.
The interaction between electrons and holes in this setup has an interesting side effect -- it generates light! In the next section, we'll find out exactly why this is.

I will continue the topic unfinished yesterday.The main topic for today is what is diode and what inside diode.
A diode is the simplest sort of semiconductor device. Broadly speaking, a semiconductor is a material with a varying ability to conduct electrical current. Most semiconductors are made of a poor conductor that has had impurities (atoms of another material) added to it. The process of adding impurities is called doping.
In the case of LEDs, the conductor material is typically aluminum-gallium-arsenide (AlGaAs). In pure aluminum-gallium-arsenide, all of the atoms bond perfectly to their neighbors, leaving no free electrons (negatively charged particles) to conduct electric current. In doped material, additional atoms change the balance, either adding free electrons or creating holes where electrons can go. Either of these alterations make the material more conductive.

HOW LED WORKS?
Hello,world.
I will show you some plain science for LED technology and in the following days
I will show you some plain science for LED technology and in the following days
Basically, LEDs are just tiny light bulbs that fit easily into an electrical circuit. But unlike ordinary incandescent bulbs, they don't have a filament that will burn out, and they don't get especially hot. They are illuminated solely by the movement of electrons in a semiconductor material, and they last just as long as a standard transistor. The lifespan of an LED surpasses the short life of an incandescent bulb by thousands of hours. Tiny LED are already replacing the tubes that light up LCD HDTVs to make dramatically thinner televisions.
In the next article, we'll examine the technology behind these ubiquitous blinkers, illuminating some cool principles of electricity and light in the process.
