LED Engin Debuts Multi-die IR Emitters
LIGHTimes News Staff
August 26, 2014...LED Engin, Inc. of San Jose, California USA, announced four new families of
dual-junction infrared (IR) emitters. The new families of IR emitters include
the first 4-die IR emitters. The company claims that the 4-die LZ4 are the
world's most powerful IR emitters, providing 6X the flux density of
conventional emitters. LED Engin says that the LZ4 offers six times the range
and resolution of surveillance and security systems of conventional IR
The company contends that its single-die IR emitter provide 70% more output
than conventional single junction IR emitters. Each die in both product
families has two serially-connected junctions, boosting output with two radiant
surfaces. A continuous 5A pulse drive enables a short output burst for even
greater range. The emitters are designed for IR systems operating at up to
At 1A drive current, the LZ4 and LZ1 emitters come in 940nm and 850nm
versions and produce 4.5W flux and 1.15W output respectively. The packages are
tiny: 7 x 7mm for the LZ4 and 4.4 x 4.4mm for the LZ1. According to the
company, the small footprint of the two emitters enables the design of very
small, discrete fixtures.
The emitters have thermal resistance 50% to 75% lower than competing parts:
2.8°C/W for four-die products and 6.0°C/W for single-die. A proprietary CTE
matched and multi-layer ceramic substrate allows the use of smaller heat sinks
for more compact fixtures.
The company says that the emitters’ integrated glass primary lenses
are far more robust than molded silicone types and do not degrade over time. A
suite of complementary total internal reflection (TIR) lenses, in beam angles
from 8 to 40 degrees enables fixtures with narrow, longer-distance or wider,
LED Engin says that the optimized thermal and optical performance of the
packaged materials ensures consistent and reliable operation throughout the
emitters' lifetimes, particularly in outdoor environments with high humidity
and high ambient temperatures.
"Equipment manufacturers in established markets such as surveillance,
transportation and machine vision, and newer businesses in biometrics and
gesture recognition, are all looking for ways to differentiate their products
through improved performance, smaller size and lower energy consumption. Our
new emitters satisfy these requirements uniquely," said Uwe Thomas, VP of
The IR Dual Junction emitters are available now from LED Engin and its

Elation EZ4 LED Display and Elation LED Luminaires Installed at Qzone in Quil Ceda Creek Casino
LIGHTimes News Staff
August 26, 2014...Quil Ceda Creek Casino, located on the Tulalip Indian Reservation north of
Seattle, installed an Elation Professional EZ4 LED video screen in addition to
Elation Platinum Spot LED II moving heads and EPAR Series LED fixtures. Opened
in April 2014, Qzone functions as a music venue, sports bar, and café and even
holds corporate meetings occasionally. The space, which originally started as a
nightclub before its convertion to a gaming room and now Qzone, is located just
off the main Quil Ceda Creek Casino gaming floor. The client wanted to offer
customers different options and events in order to draw them onto the
Agility was called in to design, build and install the lighting and video
package six months prior to opening. Agility initially planned on a 6 mm pixel
pitch panel for the centerpiece LED video screen. “Venues of this
type are relying more and more on LED walls,” said Agility’s
Rob Johnson, account manager on the project. “Because the LED screen
in Qzone was to be the centerpiece of the room and be used for a variety of
purposes, we were a bit concerned about the pixel pitch. We took a trip to the
Elation headquarters in L.A. where we had the chance to compare the 6 mm screen
with the 4 mm and came away convinced the 4 mm EZ4 was the best choice for this
Elation's 8 ft. x 12 ft. EZ4 LED screen was installed directly behind a 20
ft. wide by 13 ft. deep stage served as the primary presentation platform and
hosts live music and assorted acts. The LED screen is hard to miss from the
venue’s entrances. “It’s the focal point of the room and
looks great when you enter. It even looks good when you’re close to it at
the front of the stage,” Rob stated. Rob cites the EZ4’s easy
assembly, price point, and versatility as factors in its choice. “The
old club had a projector and screen but you can’t use that type of
technology when you have a performer or speaker on stage. The EZ4 is a real
multipurpose screen for a multipurpose room and gives the venue a lot of
The EZ4 is the company's highest resolution LED panel. It offers high
density of 10,816 pixels (104 x 104) per panel for sharp and clear picture with
vivid colors. The EZ4 screen can serve as a visual jukebox to play music videos
or simply to watch TV. It also acts like a big computer screen for corporate
meetings and presentations.
Guests to Qzone can get up close and personal to their favorite sports teams
with the display’s superior image quality and 1,200 Nits of brightness.
The display also serves as the the high quality visual backdrop for bands and
performers who need to run video and graphics. Elation Media Master Express
media server manages and plays back video and graphics for performances and
Rob specified LED lighting for its many benefits including power savings.
The Qzone lighting system includes Elation 135W Platinum Spot LED II color and
pattern changing moving heads and the EPAR Tri LED lights, which are both
mounted on a Global Truss system hanging over the dance floor and stage. Rob
chose the Platinum Spot LED II’s positioned on finger trusses over the
dance floor, for their compact size and attractive price. Their compact size
fit in well with the room and its short trim heights. “They actually
make the room look bigger and taller,” he said.
EPAR Tri RGB LED lights used for band washes provide color wash from 20 ft.
upstage and downstage trusses. The EPAR QA fixtures with their added amber LED
for extended color range and effective color temperature control, highlight
speakers on stage. Qzone hosts bands, DJs, comedy acts and other events and
performances that test the reliability and versatility of EZ4 LED screen and
the LED lighting daily. Rob reports that since its installation earlier in the
year, the system has held up very well.

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.
Download the 2014
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
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
The participants drew several conclusions:
- Achieving the targeted color point adds complexity and cost to the
luminaire manufacturing process especially in applications demanding tight
- 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
- Luminaire manufacturing is now putting less emphasis on the lamp-fixture
paradigm and placing more emphasis on integrated luminaires minimize cost
and maximize efficiency.
- 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.
- 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.
- 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
- 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.
- 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
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
"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

hanging and stacking for large events, concert tours and exhibitions. The
company claims that the finest pixel pitch and outstanding color processing of
the Black OnyX ensures superior performance in lecture halls and TV studios.
Jason Lu, ROE Visual's General Manager, commented, "In the LED industry, it
is obvious that a single product is insufficient to meet the demands of
customers. Because customers need a complete set of solutions, Black OynX, as a
newcomer who wants to surpass the formers, has to develop such solutions rather
than a simple product. Therefore, we design and promote this product by
carefully considering the requirements and ideas of customers prior to and
after the purchase, which enables our customers get maximum value from this
For Audi Shootout, Roe Visual shipped a 7-square-meter Black OnyX display to
Europe on August 1. ROE's Black OnyX will be showcased at PLASA LONDN(Oct. 5-8)
and LDI LAS VEGAS(Nov. 21-23) in 2014.
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
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.”
