An independent panel of lighting professionals judges the LFI awards, which recognize products that exemplify innovative design. The 2014 LFI award winners were chosen from among 261 entries spanning 14 categories.

University of Michigan Researchers Develop Metal-free Phosphorescent OLED
LIGHTimes News Staff

July 17, 2014...Researchers from the University of Michigan claim to have produced a metal-free Phosphorescent OLED. The researchers note that fluorescent LEDs can produce light from up to 25 percent of the electrons that pass through them. However, phosphorescent organic LEDs can potentially turn every electron into a ray of light, but achieving this efficiency with inexpensive materials is difficult.

The researchers note that while carbon-based, or organic, semiconductors are much cheaper than inorganic semiconductors, today's organic technologies employ metals in the semiconductor to enable phosphorescence. According to the researchers, these metals and their incorporation into the semiconductor material raises the price and sometimes makes the material toxic. Now, the team led by Jinsang Kim, a professor of materials science and engineering, has devised bright, metal-free, phosphorescent OLEDs.

The difficulty was getting the semiconductors to produce light rather than heat. The researcher pointed out that electrical charges in a semiconductor can produce light in one of two ways. About one in four of the charges can cause fluorescence, resulting in the 25 percent efficiency limit for fluorescent LEDs. The other three in four can go towards phosphorescence, emitting slightly lower energy light than fluorescence, the researchers said.

Organic semiconductors reportedly tend to loose about 75 percent of the energy from electricity in producing phosphorescence. Instead of creating light, 75 percent of the electrons generate vibrations in the surrounding molecules, heating the material. The researchers note that while incorporating metals can improve phosphorescent emission efficiency, going metal-free requires a different solution.

"That's why phosphorescence from metal-free organic materials in nature is very rare," said Min Sang Kwon, a materials science and engineering postdoc in Kim's lab. One example, he added, is the Hope Diamond.

The researchers indicated that the phosphorescent OLEDs that they developed can reveal the presence of water under backlight. Water reportedly causes the polymers in the phosphorescent OLED they created to break, changing the material's phosphorescent light (green) to fluorescent light (blue), according to the researchers.

The team demonstrated that the stiff lattice structure of the OLED they created helps to stifle vibrations so more energy could be released as light. The material's crystals produced light from 55 percent of the charges. However, according to the researchers, it is very difficult to produce high-quality crystals consistently in manufacturing.

The researchers altered the molecules so that they would structurally bond with a transparent polymer. The team heated and dried a solution containing the new phosphorescent OLEDs and polymers, and the molecules assembled themselves into a stiff matrix. This structure allowed 24 percent of the charges to produce light. While this efficiency level is only about as good as fluorescent light, the team is attempting to devise a complementary way to improve the efficiency further.

"We demonstrated that increasing the intermolecular bonding strength could efficiently suppress the vibrational loss of the phosphorescent light," said Kim. "This finding provides an insight into molecular designs for achieving energy-efficient and inexpensive light-emitters, ideal for practical devices."

The presence of water reportedly breaks up the bonds that enable the charges to fluoresces (producing green light in this material). However, when the bonds break, the OLED switches to the fluorescent mode, emitting blue light.

"We can see the change from phosphorescence to fluorescence, and we know some water is there," said Kwon.

The material could lead to simple sensors for detecting water. The researchers detailed their findings in a paper in Angewandte Chemie. The Samsung Global Outreach grant funded the research.

SSL Design News Staff

July 17, 2014...Cree has begun leasing an 80,600 square foot warehouse located on Weck Drive in Durham, North Carolina to store products awaiting shipment to distributors. Mike Watson, vice president of product strategy at the Cree, reported that because the space is being used as a warehouse, “minimal new hires would be tied to this space specifically, potentially one-to-two jobs if any.”

Lakewood Church Upgrades Displays with Higher Resolution Daktronics LED Video Displays
LIGHTimes News Staff

July 17, 2014...Lakewood Church in Houston, Texas got two new LED video displays from Daktronics Inc. of Brookings, South Dakota USA. Daktronics designed, manufactured and installed two new LED video displays to replace the existing Daktronics displays with a higher resolution display that features 4-millimeter line spacing in a full black package.

The church uses the displays to show inspirational images and stories during service or reveal IMAG (Image Magnification) shots as well as live video of the sermon and song lyrics that allow the congregation to follow along. The feed shown on the new LED displays is the same video shown on the video displays inside the church.

The display installation continues the nine-year relationship between Lakewood Church and Daktronics. The installation employs the existing structure to support the new displays that measure more than 12-feet high by 22-feet wide that replaces the two previously installed 8-millimeter pitch displays positioned on each side of the main service platform. Installing each display took roughly five days between Dec. 1 and Dec. 13.

"We started tearing down one of the old displays after the final service on Sunday and had the new display installed and operational before the Saturday service at the end of the week," said Nathan McGillivray, Daktronics project manager of the installation. "It was critical for Lakewood to have zero display downtime, so we installed one display the first week and the other display the following week. Services went off without a hitch and with full video display functionality."

"After the displays were installed, the wardrobe and makeup departments had to be notified of everything that was now visible on the new high-definition displays," said Joel Henie, Daktronics sales representative.

Henie said, "A trip to the recent installation at Saddleback Church really helped confirm Lakewood's choice to upgrade with Daktronics."

The upgrade reportedly offers image clarity and contrast that now makes everything much more visible to the audience, from lint on clothing to blotches of makeup and powder.

Harvatek Corporation Licenses Technology for White LEDs with Silicate Phosphors from Toyoda Gosei
LIGHTimes News Staff

July 15, 2014...Harvatek Corporation (Harvatek) and Toyoda Gosei Co. Ltd (TG) have entered into a license agreement relating to silicate-based LEDs. Harvatek Corporation is a Taiwan based manufacturer of SMD LEDs. Toyoda Gosei Co. Ltd. is a Japanese company that pioneered gallium nitride-based LEDs.

TG, together with Tridonic Jennersdorf GmbH of Austria, Leuchtstoffwerk Breitungen GmbH of Germany, and Litec GbR of Germany form the “B.O.S.E. Consortium” whose basic patents relate to technology for generating white light using blue LEDs and novel yellow silicate phosphors. Silicate phosphors are packaged with blue LED chips to produce high-brightness white LEDs with high-accuracy. Primary applications of such white LEDs include GPS, laptops, cell phones, and other small displays, accounting for a large share of today’s global LED market.

The B.O.S.E. Consortium offers two different licensing schemes: a “Device License” for the use of the white LED light technology covers the application of the silicate phosphor to a blue LED and a “Material License” for manufacturing and marketing of the silicate phosphor materials. TG has reportedly granted a device license to Harvatek, a Taiwanese LED company, to employ the patented white LED technology.

The License Agreement between TG and Harvatek allows Harvatek to manufacture and offer white LEDs using silicate phosphors covered by licensed patents. Through the license agreement, Harvatek now joins the pool of white LED manufacturers having licensed B.O.S.E. Consortium’s silicate-based white LED patent family. Harvatek and TG reportedly look forward to exploring new business opportunities and future cooperation based on the agreement.

FDA Approves New Pulsaderm LED Blue Light Therapy Device for Acne Treatment
LIGHTimes News Staff

July 15, 2014...Pulsaderm, the U.S.-based skincare device company, announced the launch of the FDA-Cleared Pulsaderm LED Blue at the 2014 Cosmoprof North America. The FDA-approved Class II Medical Device is available for $189. Pulsaderm designed the device with blue LED technology to provide a non-invasive and painless treatment for mild to moderate inflammatory acne. Pulsaderm LED Blue reportedly offers a safe, effective, and affordable alternative with competing FDA-approved light therapy devices which often sell for well over $500. Pulsaderm has made its LED Blue into an over-the-counter version of the blue light therapy that many dermatologists use.

"We are ecstatic that Pulsaderm LED Blue has been rigorously tested and approved by the FDA," said Pulsaderm founder and CEO Yvonne von Berg. "Following the enormous success of the launch of Pulsaderm and Pulsaderm Buddy facial cleansing brushes, adding Pulsaderm LED Blue seems like a natural addition to the brand's growing line of affordable and effective beauty products."

The device employs blue light at a wavelength of 415 nanometers (nm). At the device's light frequency and intensity, the light penetrates into the skin's pores to activate light-sensitive porphyrins, in the outer cell membranes of acne or acne-causing bacteria. Certain wavelengths of light cause porphyrins to produce free radicals. These free radicals ultimately kill the acne-causing bacteria without harming healthy skin. The device utilizes 97 non-damaging LED lights for nearly four times as much power as most of its competitors. According to the company, the brightness guarantees faster results for clearer, blemish-free skin. Blue light therapy is 100 percent natural, non-invasive and drug-free acne treatment process with no short-term or long-term adverse side effects. The company boasts that the gentle and painless therapy reveals visible improvements with each use.

"With innovative advancements serving as the backbone of Pulsaderm, it's in the brand's DNA to revolutionize skincare," added von Berg. "All of the Pulsaderm products were created in an effort to prevent and resolve skincare problems at affordable prices. By incorporating the latest cutting-edge technology in each product throughout the line, Pulsaderm aims to deliver a new sense of clean."

DesignLights Consortium Racks Up 50K Listings
Commentary Staff

July 8, 2014...In 1996, the DesignLights Consortium was founded as a regional non-profit whose mission was to serve the Northeast and Mid-Atlantic to accelerate energy efficiency in the building sector through public policy, program strategies and education. As a project of Northeast Energy Efficiency Partnerships (NEEP). In its own (correct) words, the DLC has "driven the lighting market towards innovation by providing information, education, tools and technical expertise for cutting edge technologies. We were pleased to host a talk by NEEP and the DLC back at our 2010 SSL Summit, when they were just kicking off a program that was intended to accelerate the adoption of LED lighting by creating a more streamlined qualified product list for commercial applications, now affectionately known as the QPL.

While we all see the EnergyStar program chugging away happily today, the backdrop to the DLC and QPL at the time was not quite so smooth. EnergyStar was struggling with the dual (or maybe even triple) challenge of working out a long-lasting, well-organized standard that didn't necessarily obsolete incumbent technologies. There was also the whole challenge presented by the good old RLF (Residential Light Fixtures) spec, which needed to be reconciled into the whole EnergyStar scheme of things. LEDs weren't really at price parity with much of anything at that point, but we all knew where they were headed, and what they could do, so the desire was to set a high-enough bar that any LED related standards wouldn't be obsoleted in a year or two. By setting the bar on LED products higher than on the incumbents (CFLs, mostly), the result was an apparent double standard. Well, not apparent, but actually a real one.

On one hand, it made sense that you didn't want to strip the CFLs of their rebate-eligibility status, especially since it had taken them a decade or two to final start producing some decent quality light. Some energy savings is better than no energy savings, and CFLs were affordable. LEDs weren't necessarily so in nearly the numbers of applications they are today. So we (the LED lighting industry) cried foul and the program involvement wasn't explosive to start. That was also the time when the DOE brass caved to the EPA brass, and suddenly energy was suddenly deemed more of an environmental issue than, oh... say... an energy issue. And egg farms should be overseen by the Heath and Human Services, not the Food and Drug Administration, or Department of Agriculture, because if you eat too many and get no exercise, smoke and drink to excess, those nasty eggs are a health risk. (Why yes, yes we are still bitter about that whole deal...). EnergyStar was rigorous for LEDs, and if you qualified, it was a rousing endorsement, that stacked you right on par with mediocre performing fluorescents... big whoop.

Meanwhile, utilities were eager to incentivize decent quality LED lighting products in the commercial marketplace (the one where the lights are on all the time), but found themselves short of EnergyStar takers, as well as short of certain useful categories. Northeast energy stakeholders said enough is enough, and in stepped NEEP, who quickly recruited stakeholders nationwide to back the DLC's efforts to fill the gaps, as well as implement a more streamlined process. Perfect performance wasn't as important and decent quality, and things caught on quickly. By 2011, pretty much everyone recognized that EnergyStar or a DLC qualified product listing were good enough for most incentive programs. You can check out the easy to comprehend qualification criteria summary here. Basically, they were able to be nimble enough to include new categories, such as LED troffer retrofit kits, as a recent example, and get quick stakeholder buy-in without the long development, review and feedback periods that are the necessary inconveniences of a bureaucratic engine (while we wish common sense could always prevail, it doesn't, so it's a good thing that the wheels of vehicles like the EPA have certain statutory brakes on them... All hail the free(er) market!). If you're unfamiliar with the DLC QPL, also be sure to check out the overview of product submission criteria here. It ties into a number of EnergyStar approaches, but they just seem to be able to keep the categories caught up with the technology.

So fast forward to nows-ville, and I think everyone can be impressed by this week's news that the DLC QPL has passed 50,000 product listings. Here's the announcement:

DesignLights Consortium® SSL Qualified Products List
Surpasses 50,000 High Efficiency Lighting Products

With growing product list, DLC remains at forefront of fast-moving industry

LEXINGTON, MA, June 30, 2014 – The DesignLights Consortium®, an international commercial LED lighting qualification program, recently saw its Solid State Lighting (SSL) Qualified Products List (QPL) surpass 50,000 products. The list is a leading resource that distinguishes quality high efficiency LED products in the commercial sector. It sets the bar for efficiency program incentives across the U.S. and Canada while influencing performance and quality in manufacturer product development.

With this increase in qualified products on the DLC QPL, luminaire and component manufacturers, energy efficiency program administrators, and others in the SSL industry continue to improve energy efficient lighting technology with the latest most innovative and high-performing products.

The DLC, a Northeast Energy Efficiency Partnerships (NEEP) project, promotes quality, performance, and energy-efficiency in commercial-sector lighting through collaboration among its stakeholders. These are federal agencies, regional and state organizations, utilities, and energy efficiency programs throughout the U.S. and Canada, as well as luminaire and component manufacturers, lighting testing labs, lighting designers, and industry experts.

“The DLC QPL is having a real impact on commercial lighting. The utilities are embracing its use in assuring the best in quality and energy efficiency, and manufacturers are eager to get on board,” said Irina Rasputnis, NEEP Commercial Program Manager. “Hitting this milestone so soon after raising the qualification requirements shows that DLC and the utility programs are significantly improving the LED lighting market. This is a great benefit to customers as they light their businesses, stores, institutions and offices”.

As the QPL grows, the DLC has identified additional ways to increase the list’s value as it relates to user’s needs. It is investigating processes to test and tier products, which will help to distinguish products on the list, provide quality control, and identify those products performing above baseline requirements.

The DLC continues to improve and evolve the QPL to increase value for its users. In addition to periodically revising its technical requirements, the DLC continually monitors potential new product application categories to add, it develops policies and procedures to keep the list honest and accurate, and it monitors industry testing procedures in order to keep its processes streamlined and up to date. The result is a resource that truly sets the bar for energy efficiency and quality in the commercial LED sector.

Thanks DLC!
