FGH Gets New Vision Signage at Bradford Facility
LIGHTimes News Staff
February 2, 2012...New Vision Signs & Graphics based in Bradford, UK, has installed illuminated signage at the warehousing facility in Listerhhills of Bradford of Freemans Grattan Holdings' retail group.
The massive lettering for the sign at the FGH gatehouse on Thornton Road is 5 meters high and spans 6 meters between two vertical pillars.
Tony Stead, business development manager of New Vision in the city’s Ventnor Street, said, “The project was challenging due to the scale of the signage and its position on the gatehouse structure. We called in a structural engineer to design the steel support frame."
Stead added,
“The letters are fabricated in steel and house low energy LED light modules, creating a subtle ‘halo’ illumination at night. The sign is very imposing and forms an impressive welcome to FGH’s Listerhills site – both day and night. "

What is the DOE's role in technology development for LED lighting?
Guest Commentary: James Brodrick, SSL Program Manager, US Dept of Energy
January 26, 2012...We recently asked Dr. James Brodrick, SSL Program Manager for the US Department of Energy, what the sustaining role of the DOE is in the basic science and technologies underlying the LED and solid state lighting industries. Jim has been a powerful voice championing the healthy technology and market development of LED lighting, and was kind enough to share his views in some detail.
Researchers have made great progress in the efficacy of LED packages, to the point where many people are asking if they are "good enough". Why shouldn't DOE just let industry take over now and move on to other things? The answer in part depends on how much energy savings is "needed" from SSL and in part on one's assumptions about what industry will do on their own going forward.
Max Possible... As to the first question, DOE has taken the position that we should maximize the potential energy savings. The goal should be to wring all the efficiency we reasonably can out of the technology, and not be satisfied with being able to compete with some fraction of incumbent technologies. At the present time, we're perhaps a bit more than half way to what DOE believes is the ultimate capability; why should we stop now?
State of Today... The second question is a lot more complicated. Do we believe industry will continue to drive the bandwagon on their own? There is some evidence that there is competition for the most efficacious products in what have become the standard platforms: GaN pc-LEDs on sapphire or SiC. But recent efficacy gains have been realized through either lowering the current density (sidestepping droop) or by using white pc-LEDs in concert with monochromatic reds (sidestepping phosphor spectral limitations and reducing Stokes loss). Both are excellent choices but they do have their limitations. Lowering current density either with larger LEDs or more of them tends to increase costs. Using monochromatic red LEDs results in additional complexity for drivers, especially when dimming is needed, but also to account for variable ageing rates and temperature sensitivity, both of which add cost and may reduce reliability.
Take it to the Next Level... The obvious "science" opportunity is to find a way to overcome the fundamental limitations that these work-arounds are addressing: Put most simply, dramatically reduce or eliminate current droop and find a way to realize an efficient color mixed solution to eliminate Stokes loss. There are of course other challenges, especially if one moves beyond the devices into the end products. But these challenges are presently the big ones. In fact, while practical products continue to improve, we have not seen the kind of basic breakthroughs that we would like to see in a while. The greatest progress is likely to be step-like, not incremental. Finding promising "steps" that represent real breakthroughs would seem to be a legitimate role for publically supported science work.
Just do It Sooner... Another value of supporting basic development is
the notion of acceleration of progress. There is a fairly logical argument that
says industry may prefer to avoid or delay a major change in the platform, choosing
to maximize the return on investments they have already made. It would seem
to be a difficult argument to gain support for internal research if the outcome
would be to obsolete millions of dollars of expensive equipment. More effort
and funding by industry is likely to go into specific product development with
incremental but not dramatic efficiency gains, just enough to remain competitive.
So while competition may eventually approach to some extent the ultimate capability
of LEDs, it might take a lot longer, thus delaying higher energy savings.
DOE looks to focus its resources on exploring fundamental science challenges
and pathways that may lead to the next “step” or breakthrough. We
look forward to continuing the discussion with the R&D community and industry
at the upcoming Transformations
in Lighting - 2012 DOE Solid State Lighting R&D Workshop in Atlanta,
Jan 31- Feb. 2 (on-site registration is available).
