DOE Publishes 2014 SSL Manufacturing R&D Roadmap
SSL Design News Staff

August 21, 2014...The U.S. Department of Energy published the 2014 Solid-State Lighting Manufacturing R&D Roadmap. The updated Roadmap complements the SSL R&D Multi-Year Program Plan that guides the Product Development and Core Technology R&D programs. One of the roadmap's goals is to guide the Manufacturing R&D program and help direct funding solicitations for it. The Roadmap also offers guidance for material and equipment suppliers, based on industry consensus about the expected evolution of SSL manufacturing.

Industry feedback for the updated report comes from a series of roundtables with invited experts and from the attendees of DOE's SSL Manufacturing R&D Workshop that was held in May in San Diego. The 2014 Roadmap adds the discussion of the OLED manufacturing cost model. DOE says it will continue to update the Roadmap annually in collaboration with industry partners, to provide an outline of research and process development priorities, and new analysis as the technology and marketplace evolve.

Navigant Consulting conducted the analysis update. Navigant concluded that in the U.S. the annual source energy savings from LED lighting in 2013 more than doubled from the previous year to 188 trillion British thermal units (BTUs). Navigant points out that this is equivalent to an annual energy cost savings of about $1.8 billion.

While these current energy savings are significant, market penetration is still quite modest. Navigant estimates that LED-based A-lamps make up only about 1 percent of all installed A-lamps. However, the company asserts that growth is happening rapidly. Navigant also reported that from 2012 to 2013 that the U.S. installed base of LEDs in general lighting applications had more than doubled to about 105 million units.

Navigant further concluded this that the 188 trillion BTU savings is a tiny fraction that of the potential energy savings that complete adoption of SSL lighting in U.S., 4.1 quadrillion BTU. Navigant says that while widespread adoption may be several years in the future, the potential reveals the need of developing a robust, high-capacity manufacturing capability for SSL. Market adoption is likely to accelerate as prices continue to fall, and unit sales are expected to increase at a much faster rate than revenues, according to Navigant.

In response to this energy-saving opportunity, the DOE launched the SSL manufacturing initiative in 2009 to improve SSL product quality and consistency, establish a strong SSL manufacturing base, and support reductions in SSL manufacturing cost in the U.S.

Current projects that the DOE Manufacturing Initiative supports include Philips Lumileds’ development of patterned sapphire substrate technology for lighting caliber LEDs, Cree’s development of lower cost integrated LED luminaires, and OLEDWorks’ development of organic light-emitting diode (OLED) deposition technology for OLED lighting products. DOE-supported SSL manufacturing R&D projects cover much of the value chain of SSL production, including designs for lower costs, process improvements, manufacturing equipment, testing, and materials.

The DOE engaged the LED community through a "Round-Table" meeting of invited experts to review the state of LED-SSL manufacturing technology and identify areas for improvement. The DOE followed the meeting with its SSL Manufacturing R&D workshop and a post-workshop conference call held among participants.

The participants drew several conclusions:

  1. Achieving the targeted color point adds complexity and cost to the luminaire manufacturing process especially in applications demanding tight color control.
  2. Long-term color stability is still poorly understood for LED -based lighting products and (probably OLED as well). Mitigating color shift over time adds to the cost of LED lighting products. Furthermore, the participants report concludes that the ability to understand and predict color shift over time would simplify the manufacturing process, reduce manufacturing costs, and increase consumer confidence in LED lighting products.
  3. Luminaire manufacturing is now putting less emphasis on the lamp-fixture paradigm and placing more emphasis on integrated luminaires minimize cost and maximize efficiency.
  4. The report concludes that highly flexible luminaire and module manufacturing will be needed to accommodate the enormous variety of designs that customers demanded. Production lines will have to be efficient and cost-effective, even with relatively low numbers for any given product variant. The required production line improvements may call for innovative and perhaps more flexible manufacturing methods and equipment.
  5. The manufacturing of phosphors and down converters and their process of being applied to LEDs is costly, and innovations in this area could potentially reduce cost, simplify the manufacturing process, improve color quality, increase light output, and improve efficacy.
  6. The domestic OLED community could work together to create a viable OLED lighting manufacturing infrastructure and promote consumer acceptance of OLED products. Larger volume production is required to exercise the supply chain and manufacturing processes in order to identify weaknesses and opportunities.
  7. The OLED community is preparing to introduce products for lighting by examining the barriers in the adoption of LED lighting and understanding the needs of lighting designers and luminaire makers.
  8. OLED fabrication methods including vapor deposition approaches and hybrid approaches are being explored. Efforts are underway to promote a panel fabrication process solution.

The report concluded that currently, the main challenge for LED lighting is to continue ramping up production and drive down costs while maintaining product quality and consistency. The emerging challenge is to demonstrate to consumers the value that LED technology offers in terms of extended lifetime, energy consumption and added functionality while avoiding consumer disappointment.

In the short-term, the expansion of LED lighting manufacturing capacity will require the refinement of existing manufacturing approaches. Longer-term, it will require the introduction of innovative approaches to lighting product design and manufacturing.

The report asserts that the biggest challenge for OLEDs is to develop acceptable, cost-effective manufacturing processes beyond what is being done for the manufacturing of OLED displays and build demand by identifying lighting applications that play to the strengths of OLED technology.

UV LEDs from SETi Used in Newly Installed Decontamination System for Scientific Experiments Aboard the International Space Station
LIGHTimes News Staff

August 21, 2014...Onboard the International Space Station, crew members using the Microgravity Science Glovebox (MSG), can now safely perform biological research. NASA has installed a UV LED-based decontamination system developed by Teledyne Brown in partnership with Marshal for MSG. UV-LEDs from Sensor Electronic Technology Inc. (SETi) of Columbia, South Carolina sanitize liquids, air, and surfaces inside MSG within minutes. SETi developed the UV LEDs in part through US Defense Advanced Research Projects Agency (DARPA) Compact Mid-Ultraviolet Technology (CMUVT) program. The decontamination process before and after experiments with the UV LEDs helps to ensure the crew safety from biological experiments inside MSG.

MSG is a highly-specialized containment system for conducting scientific experiments in zero or low gravity. Crew members aboard the International Space Station have used MSG to conduct experiments for the past ten years. With the recent installation the decontamination system, the facility can now host life science experiments.

"We are really excited to be able to provide this new system that will enable astronauts aboard the space station the ability to conduct important life science research," said Lee Jordan, project manager of the MSG at Marshall. "For example, with this system, crews can conduct experiments related to non-human cell biology that we couldn’t do before in the MSG. The work we do aboard the space station is so vital because it helps us discover technologies that can lead to bettering our lives on Earth."

A sanitation process cleans up spills inside the glovebox and uses high power UV LEDs with sufficiently short wavelength for ultraviolet germicidal irradiation to kill any microorganisms. The sanitation process also removes airborne contaminants such as biological and chemical impurities and offers optimal accommodations for life science and cell science research. It has an exchangeable glove system that was redesigned for biological studies.

The decontamination system is available to all biological payloads that operate in the MSG and require a sterile environment. Rodent research studies will be among the first experiments to employ the decontamination system. Rodent Research Hardware and Operations Validation (Rodent Research-1) is scheduled to launch aboard the fourth commercial resupply flight of SpaceX’s Dragon spacecraft. The long-term rodent studies in space will examine the effects of microgravity on rodents that serve as model organisms.

Green Spirit Farms Chooses Illumitex LED Grow Lights to Grow Good Local Food
LIGHTimes News Staff

August 21, 2014...Illumitex of Austin, Texas, reported that the company has partnered with Green Spirit Farms of New Buffalo, Michigan. According to Illumitex, the partnership will continue its efforts of enabling independent farmers to provide locally grown, fresh food to communities across the country.

Illumitex plans to replace Green Spirit Farm's existing induction lighting at its vertical farm operations with its LED grow lights. Illumitex says Green Spirit Farms plans to use only Illumitex LED grow lights as the light source for Greens Spirit's planned expansion farms. Green Spirit tested numerous lights of various types, including other LEDs before deciding to employ Illumitex grow lights.

“We at Green Spirit Farms believe that Illumitex is the premiere lighting source for indoor horticulture based on our independent testing conducted this year in New Buffalo. We are excited to announce this fruitful partnership that will assist us in further vertical farming innovation,” said Daniel Kluko, Green Spirit Farms’ director of research and development. “Illumitex LEDS will allow us to grow more produce in less time using less energy, which ultimately is good for our business, our customers and the planet we all share.”

Green Spirit also plans on choosing Illumitex Eclipse grow lights for the systems it will develops for other vertical farms using its unique Vertical Grow Systems.

Illumitex points out that vertical farming is quickly becoming the food-sourcing solution of choice for markets and restaurants that want locally sourced, fresh produce. A city's Centrally-located, abandoned warehouse buildings can reportedly be transformed into urban farms that supply freshly-picked tomatoes, herbs, and greens locally. Illumitex recognizes the need for alternative farming methods to feed the world's growing population with a finite amount of available farmland.

“With more and more Americans relocating from the suburbs to the cities, it is becoming very important to grow fresh food closer to the population,” said Eric Anderson, Illumitex VP of marketing and business development. “Together, Green Spirit Farms and Illumitex are making that goal a reality. The controlled environment agriculture expertise of Green Spirit Farms coupled with their innovative business model and Illumitex’s LED technology is a very powerful combination.”

Mid-Power LEDs to Comprise 48 Percent of Packaged LED Revenue in 2014, IHS Predicts
LIGHTimes News Staff

August 19, 2014...The 2014 lighting end market is expected to comprise about 35 percent of all revenues from packaged LEDs, according to IHS. IHS points at that for the first time, the end lighting market for packaged LEDs is greater than the market for packaged LEDs in all backlighting combined. In 2013, backlighting and Lighting each accounted for 31 percent of market revenue, IHS indicated. IHS forecasts that Mid-power devices will make up about 48 percent of packaged LED revenue in lighting applications in 2014 and 81 percent of units sold.

The market has changed drastically in recent years. Back in 2010, high power LEDs such as 1-watt devices dominated the market, IHS noted. In the west, the percentage of revenue from mid power LEDs is lower. IHS found that in Asia however, the percentage is higher. The company points out that numerous Chinese suppliers that sell LEDs to their large domestic market primarily produce mid-power LEDs.

From 2011 to 2013, the market for mid-power LEDs grew rapidly. IHS says that this rapid growth was driven by the attractive dollar-per-lumen ratio and the availability packaged LEDs previously used for backlighting. South Korean companies such as Seoul Semiconductor and Samsung initially led this trend. However, mid power LEDs are an essential part of the packaged LED portfolios of most global companies now. Other suppliers such as Cree, Lumileds, and Nichia have followed the trend, IHS says.

While Cree is the largest provider of packaged LEDs in lighting applications. Philips Lumileds is a close second. Despite this, competition from Asian companies has increased in last few years in lighting applications.

During 2015 and beyond, IHS predicts that the share of mid-power will continue to increase. Also according to IHS, the proportion of chip-on-board (COB) LEDs of the packaged LED market is growing and playing an increasingly important role because companies are designing completed lighting products for a wider variety of target end markets. IHS says that high-power LEDs are still popular in areas such as street lighting and should retain a strong presence in the market.

Excluding lighting, the rest of the LED market is almost completely flat from year–to-year. IHS predicts that the rest of the packaged LED market will remain flat until 2019. The lighting market, led by mid-power LEDs, will drive the growth, IHS contends.

Daktronics Installs Lagest Ever Display at Ector County ISD High School
LIGHTimes News Staff

August 19, 2014...Daktronics supplied and installed the largest display that it has ever installed at the high school level for Ratliff Stadium of Ector County ISD (ECISD). Ratliff Stadium in Odessa, Texas is home to Odessa High School as well as Permian High School of "Friday Night Lights" fame. The company also recently installing the largest display in college football at Texas A&M University's Kyle Field and the largest display in professional football at the Jacksonville Jaguars.

Daktronics notes that ECISD's new display is one of the largest in all of high school sports. The display with a 15HD pixel layout measures about 27 feet high by 50 feet wide, a little more than 1,330 square feet. It's size makes it larger than displays at three professional stadiums including the New Orleans Saints, San Diego Chargers and Oakland Raiders.

Daktronics originally installed the district's previous video display in 2005 that was less than 400 square feet. This display is still being used in the stadium. ECISD is apparently the only high school in the nation that uses two two displays with full video capability for a combined 1700 total square feet of video space.

The Daktronics Sports Marketing team helped ECISD secure 1.2 million dollars of equipment and and more than 2 million dollars in ad contracts over ten years. With the assistance, the district was able to pay off the existing equipment, which will stay where it is. The district is also expected to pay off the new equipment two years sooner. Any revenue generated above obligations is returned to the district.

DRSA Wins Contracts to Refit Yauchts with LED lighting
LIGHTimes News Staff

August 19, 2014...DRSA, a supplier of marine LED lighting, recently secured more than 12 major contracts to refit yachts ranging between 100’ and 175’ with LED lighting. According to DRSA, refitting yachts with LED lighting that have dimming capabilities is now in high demand because the technology for LED lighting has finally made its way to the yacht industry.

“We have dramatically increased our focus on designing, creating and sourcing LED light products over the past year as we have seen significants benefits in the marine industry,” said DRSA president Cathy Smith. “LED lights are smaller in size, brighter in appearance and lower in heat emissions. Also, we have now been able to identify solutions to properly dim LED lights on board, so anyone with a yacht going thru a refit - or a used build - is well advised to look at these alternatives,” Smith added. For more than 25 years, DRSA has designed, developed, manufactured, and imported luminaires, light bulbs and LEDs to illuminate entire vessels from bow to stern.

DRSA will be showcasing its products at the International Boatbuilders Exhibition and conference (IBEX) 2014, September 30-October 2 at the Tampa Convention Center in Tampa, Florida.

Commentary & Perspective...

The Light We Do, and Don't, Want
Commentary Staff

August 14, 2014...In a mostly annual trek into parts mostly unknown (to us, anyway) to see what is going on with lighting in the real world, we were struck two things. 1) There still isn't all that much of the light we want, and 2) There is still a lot of light we don't want. While few probably fell off their chair on that revelation, we all tend to have so much legacy lighting around us that we tend not to reflect too much on what we're missing, much less on what we're getting that we really shouldn't be.

One of the first stops on the tour was into The Caverns at Natural Bridges, in the mountains of Virginia. Lots of natural wonder to be found in a mostly horizontal cave that heads into a mountain, which therefore gets deeper and deeper "underground" as you head in. That means more opportunity for water to pick up minerals on its way down, and when they hit the roof or floor of the empty space, they give the minerals back. That water also carries clay with in this particular cavern, so you get pretty impressive "mudstones" that can be scrubbed white for a day or two (also right there on their website). And you get green stuff -- algae in this case, that made it down there on some air currents, and grows courtesy of the moisture and the artificial light. Nice, broad spectrum incandescent, to enhance our viewing pleasure, is prevalent, and with close to 8 hours a day on time, it's plenty to grow. It's the light we don't want. The guide pointed out where they had begun to changeover to LED lighting, that would "supposedly" help with that. The company apparently specializes in that kind of thing. Don't know who it is yet, but hopefully they'll let us know their formula, which we'd expect to be removing some spectra that algae like, and which the viewers won't necessarily miss.

The next stop was the Smithsonian Air and Space Museum. A look at the high ceiling revealed some nice looking area lights that fit the model of Beta (now Cree's) original Edge product line. The optics were well done, and weren't obnoxious to look toward. With good color rendering, it made it the kind of light we do want. Unfortunately, the LED lighting doesn't appear to have gained overwhelming traction in that facility, as a number of displays protected from curious fingers behind a protective glass barrier required the traditional "bob and weave" to see it all against the glare in the glass. The original Wright flyer (the, the original... very cool) was illuminated by a beachy sort of Kitty Hawk sand dune kind of towards sunset yellow. Quite emotionally stirring, and very deficit of helpful wavelengths when it comes to visual acuity. LED lighting shouldn't be challenged to provide a cure for that - ambiance plus fidelity, all for just a few pennies per lumen. Even better would have been a bit more experiential display, with the light giving us the full sunrise-midday-sunset playback of a typical day over the course of 10 minutes, along with a background soundtrack of seabreeze, sputtering engines and enthusiastic hollering (I'd recommend they check out Telelumen's solution for the realistic light playback -- Yo, Smithsonian. Tell Steve Paolini we said "Hi").

At the Smithsonian Art and Portrait gallery, CMH and halogen were the watchwords. One of the few artifacts in the extensive gallery was a civil war sword. The sign read (paraphrase), "This is a replica. The original is carefully stored away to prevent it from being damaged by light." There's a thrill! A genuine, real live, carefully detailed replica. We could have gotten that in the wax museum in Gatlinburg, TN (lots of LED lights in that town... sort of Orlando in the mountains). In a room only lit by artificial light, should we really need to protect a treasure from the damage that light can cause? Maybe we can put in the kind of light we want, and get rid of the kind we don't.

The good news here is the LED lighting is in its infancy when it comes to what we know, or don't know, about light. As we've said many times before, incumbent technologies didn't offer a particularly cost-effective solution set to test each and every wavelength. LEDs open that door, and with that, our knowledge. We've mentioned it a lot, but it's only because we don't want anyone to miss it: This whole thing is about what our light can do for us, and very quickly, it will also be about what our light has been doing too us. Up til now, anyone has been able to claim, "That's all we had." No one was suing their employers for using kerosene lamps, since the choice then was those, or darkness. When Edison heated that wire, we quickly had good, healthy (enough) light. Then came the longevity and efficiency of fluorescent which quickly devolved to devising the bare minimum of phosphor spikes to fool our eyes into thinking it looked ok, but do we really know what we were missing? Soon enough, we'll know what the lack of, or extra of, in terms of photons were or weren't doing for us. Then there will be published papers that get cited in the lawsuits for decades of bad lighting causing many of the ails of society. And the justifiable defense will be "We didn't know." All will be forgiven, with the out of court settlement being total conversion to "natural" LED lighting (with none of the bad additives).

This will be way better than that incandescent bulb ban. We promise.
