Black Friday Lightens Up with LEDs

The day-after-Thanksgiving-shopping-mayhem known as Black Friday has officially come and gone, but the repercussions (or shall we say benefits) of all that purchasing will be felt for months. According to the 2009 holiday survey by Pricegrabber.com, 45 percent of consumers were planning to shop on Black Friday and Cyber Monday, with 80 percent planning to make a purchase on Black Friday and 66 percent on Cyber Monday. And I can vouch from a personal standpoint that it was crazy out there, people! I happened to be in Chicago on that fateful Friday, and let me just say, Michigan Avenue was nothing less than insanity. But given the struggling economy, that’s not a bad thing. In fact, the numbers were better than expected by retailers, who attracted shoppers with hard-to-turn-down sales. (Again, I can vouch for this from a personal perspective. There must have been something in the water at Macy’s because those sales ladies were downright hypnotic with their powers of persuasion…but I digress.)

LEDs were no exception this season; more shoppers than ever purchased decorative holiday LED lights. That’s a great thing for our planet and our nation, since the U.S. Department of Energy estimates that if every household switched to using LED holiday lights, the country would save approximately $410 million in electricity costs. While the recession is still affecting most Americans, that didn’t stop them from spending a little extra for LED lights. While a string of incandescent lights costs about $2 and a similar string of LED lights costs $5-$15, the LED lights will last more than 20,000 hours (that’s up to 40 holiday seasons!), are less likely to break and remain cool to the touch, so they’re safe for kids and to use on that dried up Christmas tree! LEDs use 70 percent less energy than incandescent lights and they contain no mercury like CFLs do.

In fact, due to the increasing popularity of LED lights, IKEA plans on phasing out incandescent lights over the next five years. That’s a big statement from a huge retailer, attesting to the popularity and staying power of LEDs. What can we say, we told you so?

Give Thanks for LEDs!

led_turkey1As I’m enjoying my tryptophan haze on the couch (that’s the stuff in turkey that makes you feel sleepy and happy), I thought I’d take a minute to give thanks for LEDs, because they really do make our world a better place. I mean if you think about it, we humans require a lot of light, and thanks to LEDs, we can start lowering our energy consumption despite the fact that we like (and need) to lead fairly illuminated lives. That makes our planet a healthier place and makes our wallets a little fatter too.

But enough with all the touchy feely stuff. Another reason I like LEDs is because they’re FUN! I mean, would you be able to make an LED turkey centerpiece with incandescent or flourescent lights? Probably not, and if you did it would probbly get too hot and burn the house down! But not trusty LEDs. They stay calm, cool and collected in any situation! Just check out the hilarious and downright cute turkey centerpiece made by Sparkle Labs. The ingenious folks at SL have created a simple template you can download, print and cut out in the shape of a turkey. Then, you can either use the Discover Electronics breadboard kit they’ve designed for the job, or just some LED christmas lights you have lying around to light it up!

Thanks to Technabob.com for turning us onto this colorful and fun way to give thanks for LEDs, by appreciating them right on your dinner table, along with all of the delicious food you cooked!

Happy Thanksgiving, everyone!

LEDs: Up, Up and Away!

If anybody out there still questions the technology behind LEDs, here’s yet another reason to stop doubting. LEDs are joining the ranks of some of the most sophisticated technological innovations known to man; we’re talking man-on-the-moon and ice-on-mars stuff. That’s right; LEDs are going to outer space. NASA has agreed to a two-year commitment with Lighting Science (an LED manufacturer) to develop a “high illumination and good color rendering LED light fixture for space exploration,” according to a Lighting Science Corporation press release.

It’s only fitting then that LEDs are the chosen light source to accompany man into the ethers. After all, their long lasting, high quality and durable attributes make them perfect for space travel. LEDs can withstand extremes of both high and low temperatures, and their smooth dimming and color-changing capabilities make them easily adaptable to the ever-changing conditions of space. The NASA-grade LED prototype will be developed to meet standards for space travel in such areas as “control, vibration, off-gassing, electromagnetic interference and other spacecraft issues.” One of NASA’s goals for the LED fixture is that it help them learn how to aid astronauts in establishing and maintaining healthy sleep patterns in space, a notoriously difficult task. Fred Maxik of Lighting Science says, “We hope to not only improve circadian rhythm management for our astronauts but, also to learn something that will help the millions of people who struggle with these issues here on Earth.”

Happy Holi-LEDs!

led_menorahIt’s happened. It’s that time of year again and there’s nothing you can do about it. The Holidays are indeed upon us. And while that may leave you feeling nostalgic, nauseated or a little of both, at the very least you can know that this year, you can go greener than a Christmas tree by using LEDs for all of your holiday lighting needs.

Just take your cue from the nation’s most famous Christmas tree, the 65-foot tall, 35-foot wide evergreen tree in New York’s Rockefeller center! The tree has been adorned with the same topper-a Swarovski Crystal star for several years. But this year, that same star has been retrofitted with new energy-saving lights-720 LED lights, to be specific. It’s reported that all 720 LEDs will use only about as much power as a single 100-watt light bulb, and will shine even brighter than in years past. We can see it all for ourselves when the tree is lit on December 2nd

And if you want to get in on the action and make the switch to LED Christmas, Hanukah or other holiday lights this year, you’re not alone. Apparently, certain ACE Hardware stores across the country have predicted that so many consumers will be making the switch to LEDs that they are offering to swap out incandescent lights for LED lights. Some stores are also offering recycling opportunities for your old incandescent lights. What a great idea!

And, if Christmas isn’t your thing, guess what? LEDs work for menorahs too! Just check out the above adorable LED Menorah kit from Evil Mad Science Labs. This battery operated kit lets you choose the type of lights you like the best, based on size and color. What a fun gift or-better yet- way to show your Hanukah spirit without burning the house down!

LEDs Installed to Save Lives in Japan

blue-light-prevent-suicide-asahi-jr-yurakucho-stationAccording to psychologists, the color blue helps to calm stressed people. That’s why Japanese rail operators decided to install blue LED lights in train stations throughout Tokyo: to dissuade commuters from committing suicide by jumping in front of trains.

It’s a grim subject, true, but it’s a fact that Japan is home to an ever-increasing suicide rate, one that has only worsened over the last year due to the international economic recession. Experts are predicting that more people will commit suicide in Japan this year than in the record-breaking year of 2003. That year, 34,427 people took their own lives in Japan, with more than 2,000 of those people doing so by jumping in front of trains.

JR East, one of Japan’s biggest train companies, gathered troubling statistics to show that suicides occurring at its stations rose from 42 in 2006 to 58 in 2007 and 68 in 2008. In the past, officials have installed barriers and barricades to hinder jumpers, to no avail. The lights offer a new solution that tackles the root of the problem: anxiety and unhappiness.

While there is no way to scientifically prove that the blue LEDs, which have been installed at the ends of several platforms throughout the country, will in fact reduce suicide attempts, Japanese officials thought they ought to try anything they could to deter passengers from jumping.

“We associate the color with the sky and the sea,” Mizuki Takahashi, a therapist at the Japan Institute of Color Psychology, a private research centre that was not involved in the lighting project. “It has a calming effect on agitated people, or people obsessed with one particular thing, which in this case is committing suicide.”

Here’s hoping that Japanese commuters “see the light” in more ways than one, and that LEDs can help them remember that life is, in fact worth living.

Starbucks Brightens the Mood with LEDs!

Well, we knew it would happen someday. Now when you’re crossing the street to go to the other Starbucks because the Starbucks you were just in was out of coffee cup lids, you can rest assured that the company is doing something good for the environment where lighting is concerned. Starbucks just announced that it will replace conventional lights with light emitting diode (LED) bulbs in 8,000 stores by March of next year. The coffee manufacturer is making the switch as a part of its overall goal to reduce energy consumption by 25 percent by the end of next year. Each store will replace its incandescent bulbs and other vacuum-and-chemical lights to solid state lighting, which is estimated to reduce energy costs by 7 percent per store.Reportedly, General Electric will be supplying the LEDs to Starbucks, and worked closely with the company to design lights that fit with the Starbucks ambiance and aesthetic. One thousand Starbucks have already been retrofitted with LEDs. According to Michael Petras, president and CEO of GE Consumer & Industrial’s lighting and electrical business, “Starbucks’ aggressive moves on the conservation front will have far-reaching environmental and financial impacts. Other GE customers will benefit from these achievements.”

And lighting isn’t the only place Starbucks is purportedly getting on the “green” wagon. According to TreeHugger, “The company isn’t often on this side of green when it comes to operations. A year ago they were in hot water for wasting 6 million gallons of water a day, all for a very lame policy for cleanliness. However, they have been trying hard to be eco-friendly, including starting BICEP, Business for Innovative Climate and Energy Policy, switching to hormone-free milk, and getting more serious about fair trade coffee.”

Well, Starbucks, our hat is off to you! Welcome to the wonderful world of LEDs!

Maybe it’s Maybelline, Maybe it’s LEDs?

10829698671Halloween has already come and gone, but I just found out about a little accessory that will make you wish the costume-centric holiday was here all over again: LED eyelashes. Yes, folks, that’s right. Someone has figured out how to affix tiny LED bulbs onto human eyelashes, creating a futuristic and in my opinion, downright rad look. The person I’m referring to is Korean artist Soomi Park, who says she created the lashes to draw attention to her belief that woman (Asian women in particular) are obsessed with having larger eyes, which they perceive to be more beautiful.

The artist’s statement includes the following about her creation: The LED Eyelash is a clever product that speaks to many Asian women’s desire for bigger eyes. It features an inclination sensor with mercury to turn on and/or off. The sensor can perceive the movements of the pupil in the eyes and eyelids. If someone wears it and moves her head, LED Eyelash will flicker following the movement.

It turns out that Park made these LED eyelashes in 2007, but buzz about them just finally made it over to the United States this year. The artist is receiving both praise and criticism for her invention. Some attest that the eyelashes symbolize the beginnings of the next big trend in fashion, sci-fi couture. Others call Park a “betrayer of her own sex,” asserting that the eyelashes encourage women to go to extremes to meet societys arbitrary ideal of beauty.

Either way, the technology behind the LED eyelashes is impressive. The sensor Park describes above allows the wearer to turn the lashes on or off with a tilt of the head, and the product is lightweight and easy to apply and remove.

Leave it up to the versatile LED to help to spearhead an important sociological debate about women’s issues and beauty ideals, or to help set the next big fashion trend. Feel free let us know how you feel about it- are LED eyelashes friend or foe to fashion? And to the women’s movement? Personally, I’ve just got one question. Do they come in purple?

Here Comes the (LED) Bride…

images1Okay, I admit it. I’ve got weddings on the brain. A certain member of my family is getting married in the near future and much of my free time is consumed with helping her plan for the big day - we’re talking cake, dress, champagne, music - the works. Now, all of those details are of course fun to plan, but the one that interests me the most is the lighting. I mean, what’s a wedding without ambiance, right?

And with LEDs on the market, wedding lighting options have really expanded. For instance, white strings of lights are usually quite popular at weddings. But old fashioned LED bulbs get hot, use a lot of energy and are heavy and difficult to work with. LEDs provide the same effect, or an even better one, but are more efficient, lightweight and stay cool no matter how long they burn. Plus, if you decide you want to get a little crazy at your wedding, LEDs easily change color. You could start with a classic white ambiance and switch to a more party-oriented, colored one as the night progresses (and the drinks add up).

And if you’re into that whole Chinese lantern look but you hate the idea of having to wire all of the lanterns with unsightly black chords, what about lighting each lantern with a battery-powered LED? This frees you up to place the lanterns wherever your little heart desires, and reduces risk of fire too! (Incandescent bulbs heat up and could potentially light paper lanterns on fire.)

But I have to say, in all of my wedding-oriented LED research, my favorite find had nothing to do with ambiance. It came from a bride whose wedding dress lit up during the first dance with her new husband! Turns out she wired the dress with 300 tiny LEDs, and during a particularly moving crescendo in the song, switched the dress on to great effect. Check out the video here.

And remember, LEDs create a healthier planet, a fuller wallet, and just maybe, a happier marriage, too. At the very least, they’ll make your wedding a day to remember!

Happy Birthday to Our Hero!

Tomorrow, November 3rd, is a very special day. That’s because it’s the day that Nick Holonyak was born, without whom the LED, or light emitting diode, might never have existed. Holonyak, considered to be the “father of the light emitting diode,” was born in 1928 in Zeigler, Illinois. As you can imagine, it takes quite an impressive mind to revolutionize the very way in which light functions in our society, but Holonyak himself was surrounded by revolutionary physicians and inventors from an early age. As an electrical engineering student at the University of Illinois, he studied under John Bardeen, inventor of the transistor. Transistors are now considered to be fundamental building blocks of any electric device - they are used as semiconductors to amplify electrical signals.

In school, Holonyak’s studies first focused on vacuum tube research, but in 1952 he switched his emphasis to semiconductors and began working in Bardeen’s semiconductor lab. It turns out that semiconductor diodes are the basis of LED lighting, and it was this decision to switch specialties that led to Holonyak’s’ invention in 1962. While he is not the only person responsible for LED lighting (several other researchers in several other countries around this time reported on semiconductor discoveries, including those of the infrared variety), Holoynyak was the first to develop a practical, visible LED light (in the color red), while working at General Electric Company. He went on publish two books, one called Semiconductor Controlled Rectifiers in 1964 and the other, Physical Properties of Semiconductors, in 1989.  He is still doing research at Illinois in the Department of Electrical and Computer Engineering. One of Holonyak’s students, M. George Craford, went on to improve upon his mentor’s invention, and created a brighter, yellow LED light in 1972.

Holonyak will be 81 years old tomorrow. Lets all wish him (and the LED) a happy birthday!
