NOTRE DAME, Ind. — There are 116 lights in the ceiling of the Purcell Pavilion on the Notre Dame campus. Because all of those lights use up a lot of electricity the university switched to LED lights.


“You actually have better color rendering. You’re going to see a truer color. What’s under an LED light source is very bright, very crisp, and very clean,” said Paul Kempf, Senior Director of Utilities and Maintenance.


Pregame introductions will now be done by simply dimming the lights.


The old lights only had two settings – on and off.


With these new lights, the Irish are sure to be one of the most visible teams in the country.


Kempf says he thinks Notre Dame is one of the first campuses in the country to use led technology on the basketball court.


Each fixture uses about 411 watts of energy compared to the old fixtures that used 1500 watts each.


Purcell Pavilion won’t be the last building in Notre Dame to use LEDs. The maintenance department is already planning to use that same technology to light the dome.

Philips Desso introduce LED Carpets - cooler and transmissive - You"ll Never Get Lost In an Airport Again

Philips to develop light transmissive carpets woven with LEDs

LED Carpets Guarantee You’ll Never Get Lost In an Airport Again

Philips has announced a partnership with Desso, a company famous for its flooring, that will see the two companies work together to develop LED light transmissive carpets. The carpets could be used for everything from delivering information to inspiration, apparently.


With a development that will surely appeal to airports, Philips has announced a partnership with flooring manufacturer Desso to produce a light transmissive LED-powered carpet that can be used to display warning messages, directions, or even fancy glowing designs. And airports are just the tip of the glowy-floor iceberg.


In an airport setting a glowing carpet would make finding the luggage carousels or a specific gate even easier if the directions were underfoot. It would also serve to make the spaces seem less cluttered, as information wouldn’t have to be crammed onto overhead signage everywhere. And casino carpeting could become even more gaudy and busy with colorful glowing patterns, helping to hide the dirt from foot traffic and encouraging patrons to avert their eyes towards the gaming tables.


Philips and Desso will be revealing more details about the initiative sometime in 2014, including the official product branding. But the two companies already have pilot projects in several markets which means the carpets do exist, and could be rolled out (get it?) in new facilities before the end of 2014.

Carpets are great until you have to whip out the old vacuum and clean up all the dirt and stuff that gets stuck in there. Carpets don’t exactly need reinventing. The shaggy floor covers are laid down and just sit there, not doing anything. Two companies want to change that and make those boring carpets actually useful by embedding LEDs in them.


Philips, makers of those awesome smartphone-controlled LED light bulbs has teamed up with Desso, a leading carpet and flooring company to “light transmissive carpets.”


The carpets are exactly what you think they are. They have LEDs right underneath their soft tops, which can display different types of digital signage or information or enhance interior spaces.


For instance, LEDs within the carpet could display arrows to direct people towards exit doors during emergencies like so:


Because the LEDs are, well, LEDs, the information displayed on the carpet wouldn’t be permanent, which would lend it flexibility in many scenarios.


“This light transmissive carpet solution is designed to engage directly with people’s senses and the eyes’ natural inclination to seek out light,” says Ed Huibers, Philips Lighting’s marketing and sales director. “The technology takes advantage of people’s tendency to be guided by the floor when moving through and interacting with space. It brings information, direction, inspiration and safety via the carpet you walk on.”


It all sounds like a great idea until you think about how advertisers are probably all over this already. With our heads already burined in our smartphones, the last thing we all need is to see tons of LED ads on carpeting all over the place. Maybe we’re being a little pessimistic, but it could happen. Still, we like what Philips and Desso are doing and we want LED carpets in our house badly, if only for all the sweet glowing action.

How One Light Bulb Can Change Your Life

What a Difference a Light Bulb Makes? People in developing countries are leapfrogging our 19th century technology.


An M-Kopa solar system, in Kenya. An M-Kopa solar system, in Kenya.


There’s a simple technology that transforms our lives every day, and yet we rarely give a passing thought to its existence (unless of course it flares out at an inopportune moment): the light bulb. And yet for more than a billion people in the developing world who lack access to electricity, this simple device can make an unimaginable difference.


Thomas Edison didn’t actually invent the light bulb, as is commonly credited; rather, he built on decades of research and perfected a practical method for delivering light powered by electricity. But because of Edison, in 1882 the first light bulbs graced buildings in New York City. A New York Herald reporter described it: “In stores and business places throughout the lower quarter of the city, there was a strange glow last night. The dim flicker of gas, often subdued and debilitated by grim and uncleanly globes, was supplanted by a steady glare, bright and mellow, which illuminated interiors and shown through windows fixed and unwavering. … It was the glowing incandescent lamps of Edison, used last evening for the first time.”


A family with a light bulb is a family with opportunities.

We’ve been reaping the benefits ever since. Consider this: Night drifts in through the window, and the room darkens. You casually stroll over and flip a switch, a movement so ingrained you barely notice you’ve done so. The bulbs blaze, the dusky shadows outside disappear. Your home once again turns bright as day. You read a book, maybe cook dinner, and the kids in the house settle in to do some homework.


But for people around the world who can’t flip that switch, their lives are ruled by that great ball of flaming plasma passing across the sky. To the extent that they do illuminate their homes after the sun dips below the horizon, they rely on candles or kerosene, both of which are expensive, dangerous, and polluting. In some areas of Africa, people spend from 10 to 30 percent of their income on refilling kerosene lamps, which are little more than tin cans with an open flame. Burning them releases millions of tons of carbon dioxide per year and contributes to climate change. And igniting them in a closed home can equate to smoking a couple of packs a cigarettes a day. Smoke from burning kerosene irritates the eyes, so students extinguish them instead of doing homework.


On the flip side, a family with a light bulb is a family with opportunities. Women can set up small shops in their homes, for instance, to sew or cook for extra money. Kids can study for school: A light may keep a girl or boy from dropping out. Families read, or may use the light to set up classes to teach others to read. A shop owner keeps his or her store open longer, earns more money, sends more kids to school—and those kids can then use the glow to read in the evenings. That’s why there are dozens of organizations around the world dedicated to nothing more than making sure that people have access to light.


Many of the communities without access to regular electricity are now leapfrogging our ancient 1800s technology. The ubiquitous incandescent bulb, the one perfected by Edison more than a century ago, basically works via a filament that, when electricity passes through, burns hot enough to emit light. But about 95 percent of that energy is wasted as heat. As a result, incandescents are being phased out by many governments; the U.S. slowly began phasing them out in 2012. Compact fluorescent lights, or CFLs, were invented in the 1940s and are significantly more energy efficient. But for decades their cooler tone turned off many consumers (though the color has gotten warmer, and CFLs have been replacing incandescents).


Light-emitting diodes, or LEDs, are the top new technology in lighting. When electricity is applied to an LED, electrons jump from one layer of material within the diode to another and give off light. They’re hardy, they last for years, and they’re incredibly energy efficient. The problem is that white LEDs are pricey. Americans might weigh the options and decide: Why shell out around $10 to $20 for an LED, even if it will last perhaps 25 times longer than the cheap incandescent?


But nearly unbreakable LEDs are easily paired with solar power, and so in poor communities, what seems excessive to us becomes a long-lasting investment that bypasses both inefficient incandescents and the lumbering power grid. Some nonprofits, such the Light Up the World Foundation, pair solar panels with LEDs. The organization Solar Sister provides women in Africa with training, marketing, and an inventory of solar-powered light bulbs. M-Kopa in Kenya provides a financing scheme along with the requisite technology; the organization sells an entire home system with solar panels, lights, and a cellphone charger, for about $200. Customers pay as little as about 45 cents a day and can pay off the debt in a year.


Companies are also focusing on the design of that LED light in the first place. D.light Solar provides rugged lights and chargers to M-Kopa and has already sold more than 1 million units. Nokero, founded in 2010 (the name comes from “no kerosene”), just this October released the latest version of their solar-powered lanterns. The elaborate $45 version can either plug into the grid or recharge via solar panels, and it includes outlets that allow users to power their mobile phones. Their simplified solar-powered bulb is only $5 to $6, the cheapest on the market. They’ve already sold hundreds of thousands of units throughout the developing world through commercial distributors, nonprofits, and governments.


That light can do more than improve someone’s financial situation: A light bulb can save a life. When Laura Stachel, an obstetrician and gynecologist in California, was on a research trip to Nigeria in 2008, the lights went out during an emergency C-section. She was able to supply her flashlight, but she quickly realized that surgeries were postponed, and people died, simply due to a lack of light. This was true not only in Nigeria, but all around Africa. She returned home and with her husband designed a so-called “solar suitcase,” now the foundation of her nonprofit, We Care Solar. The suitcases include solar panels to be mounted on a hospital roof, a battery for energy storage, rechargeable LED lights and a headlamp, walkie-talkies for communication, and a fetal heart-rate monitor. Today, these solar-powered lights are saving lives in 27 countries in Africa, Asia, and Central America. (Stachel was named a CNN 2013 Top 10 Hero.)


It may seem like a throwaway technology to us. But for perhaps 20 percent of the world population, a functioning, reliable light bulb is a godsend.

It"s Time for the LED industry to Tackle Compatibility

It It’s Time for the LED industry to Tackle Compatibility
[/caption]


Article by Jan Kemeling – Ledzworld Chief Sales & Marketing Officer (CMO)


The story behind LED development—only the 4th lighting technology developed in human history—is remarkable. The potential ahead of LED lighting to deliver real and measurable advantages—to save energy, last years longer, significantly lower bottom-line costs—is limitless. But for it to be the next great defining feature of the lighting landscape, LED lighting needs to work.


Yes, work. That’s precisely the question LED end-users, specifiers, designers, utilities and regulatory agencies ask themselves before adopting LED options for their stores and retail fronts, offices and homes. Will these alternative lighting offerings achieve what they promise?


And the simple, scary truth facing the LED industry today is often, there’s no guarantee they will.


Today, legacy infrastructure—the transformers, fixtures, and control devices already incorporated into built environments—creates unique and challenging compatibility interferences with widespread LED adoption.


What we’ve seen to date in our current, ongoing preliminary phase of LED adoption is “plug and play” applications–a customer simply installs an LED bulb into an existing fixture. Sometimes that fixture works with the LED bulb’s mechanical, electric, and thermal requirements; sometimes it doesn’t; and sometimes there are mixed results. The effect? Consumer uncertainty.


Any new technology only has a small window to prove its value. Second chances with first impressions do not exist—which is why in any market; it’s essential to capitalize on the moment of market introduction. It’s an opportunity—and a test—to gain the trust of the consumer on the first try.


The LED industry, peers, partners, and competitors, must work together to ensure full compatibility with the millions of lamps, dimmers, transformers, and fixtures on the market.


When looking at the compatibility problem, there are three separate issues to address: 1. Electrical compatibility; 2. Mechanical compatibility; and 3. Thermal compatibility.


Electric Compatibility. Common voltages in lighting systems are significantly higher than LED requirements. As a result, the transformer and dimmers often don’t operate consistently, or properly. Frequently this causes the LED to flicker and dim erratically, one lamp powering off before another, or the LED not even powering on at all.


Mechanical Compatibility. Problems arise when LEDs do not match the size and dimensions of traditional lamps. It’s simply a matter of fitting a square into a round hole—the LED does not fix the legacy fixture’s width or height.


Thermal Compatibility. Traditional light sources and LEDs operate at dramatically different temperatures. While some halogen lamps operate at 200 degrees Celsius, LED lamps must operate between a specific thermal temperature to ensure long life and safety standards. In much of the legacy fixture infrastructure, there’s no means to dissipate heat in the bulb design.


Let me be clear. Compatibility is the number one compelling problem facing the entire LED industry today. No end-user, designer, specifier will–or should—care what promises and potential LED technology holds in the future, if it doesn’t meet their needs in the present.


So while others keep the issue in the dark, Ledzworld works to guarantee our technology fits legacy lighting infrastructure. How? By proofing every one of our LED solutions against hundreds of the most commonly used dimmer, transformer and fixture applications. It’s painstaking work, but it’s this behind-the-scenes effort that gives our customers the peace of mind they need, and deserve.


We’re also innovating LED drivers that guarantee our lamps are hassle-free, and work seamlessly on a wide range of magnetic and electric transformers and in combination with commonplace dimmers.


Recently, the company launched a breakthrough MR16 LED lamp with our patented Chameleon driver. The Chameleon driver self adjusts to its environment by first detecting the transformer type, then analyzing its waveform, and finally adjusting itself to make a perfect electrical fit with that particular transformer. This innovative driver makes the company’s MR16 LED retrofit lamps truly “plug and play” devices that can be used in a wide variety of transformer and dimmer combinations. Anywhere, every time.


What’s more, the CTR functionality implemented in Ledzworld’s Chameleon driver design also provides an intelligent temperature control monitoring system. The temperature control system acts as a watchdog by continuously measuring the ambient temperature inside the driver compartment by utilizing a built-in thermal sensor embedded into the Chameleon driver chipset.


Bottom-line, our lamps work on the spectrum of magnetic transformers, in combination with most commonly used leading edge dimmers, and with a large variety of electronic transformers paired with commonly used trailing edge dimmers.


Ledzworld set out to revolutionize the lighting industry with one unshakable commitment: to develop, design, and manufacture LED lighting that meets—and exceeds—all LED technology expectations. But that starts with ensuring that our technologically progressive, best-in-class lamps work as well with older infrastructure as they do with the new.


So that a few bad actors don’t spoil LEDs reputation, it’s time for the entire LED industry to tackle compatibility, together.
