Event horizon
In his annual round-up, Dr Geoff Archenhold looks back at a momentous year of developments in LED technology and suggests that this is the dawn of a new era.
The lighting community finds itself in interesting times lumbered with the challenges of the economic credit crunch on the one hand and the disruptive change that LED technology is forcing upon established lighting manufacturers on the other. Over the last few years I have listened to many statements from all parts of the lighting supply chain stating that LED technology is not yet mature enough to be considered as a mainstream lighting technology. However during 2009 the numbers of LED doubters have dwindled significantly which proves one thing - 2009 was the year that LED technology was adopted as the future lighting technology for the global lighting industry - it was an event horizon!

It is clear that 2009 has been a year of significant change for the lighting industry with many of the major lighting brands producing financial results to send shivers down the spine of most analysts.

However the economic crisis has offered significant opportunities with large numbers of smaller companies focusing specifically on LED technology. These companies have taken advantage of the technology disruption and brought highly innovative solutions to end-users. I believe many of the smaller and more innovative lighting companies will develop the skills and understanding of the new technologies faster than traditional brands and the market will see competition that makes for an exciting time for end-users and the lighting market in general. Competition means both lower prices and higher innovation.
There are several reasons why LED lighting have become more readily accepted:
• Consumers are aware of the climate change issues with significant weather events that were supposed to happen once in a 1000 years happening within decades.
• Energy prices are high and set to go much higher so return on investment is key on customer priorities.
• LED performance has significantly improved in both efficiency and colour quality making them the light source of choice.
• LED fixtures are digital and the integration of controls is straightforward compared to traditional light sources.
• Standards for LEDs are now in place.
• The cost of LED emitters have dropped significantly during 2009 making LED fixtures more affordable.
• There is a greater choice of LED manufacturers and LED component suppliers.
others LED projects:
What to expect in 2010.
Steve Landau, Philips Lumileds suggests the following:
• Power LED products are still not generic and what’s true for one product is not necessarily true for those from other manufacturers. This means that there’s significant due dilligence that must be done by the engineers to understand how each product will perform in an application before making an LED selection. The LED manufacturers must continue to provide more, better information that allows this work to be done as easily and quickly as possible. Without that effort and understanding of the differences, it’s likely that some will make the wrong choice and the impact on their business success and customer perception could be impacted.
• Understanding system reliability will take centre stage. Without truly understanding system reliability, warranty, TCO and payback, assessments cannot be accurately calculated. System reliability does not equal lumen maintenance of the LED. It is actually a calculation that considers the following elements: electrical, connections, LEDs, optical, thermal, and mechanical. Strongly related to this is the notion that LEDs don’t fail. They do, as do all electronic components. In LED solutions, the typical approach is to use an array of LEDs. Understanding the lumen maintenance and catastrophic failure probabilities will become critical. Lastly, a clear understanding of these metrics allows systems to be optimised.
• From a product perspective we expect to see significant expansion of the product offerings available to the illumination markets where light output, CRI, and CCT are more finely defined, binning continues to improve and shrink and colour uniformity and quality get significantly better.
Conclusions
2009 has been a stunning year for Solid-State Lighting that has witnessed LED technology leapfrog CFL lighting in terms of performance and LED driver technology become even more sophisticated and flexible. LEDs have again increased the performance bar with a record 249 lumens per watt efficiency in the Nichia laboratories and CREE achieving over 132 lumens per watt for production LEDs.
2010 will be a significant growth year for LED lighting manufacturers, despite the economy, and we will see a major proportion of traditional lighting companies begin to adopt LED technologies as consumers decide to move to a greener lighting solution.
Next year will see a whole raft of colour tuneable white light products launched on the market enabling users to command the lighting environment. The use of LED technology will also see the incorporation of intelligent controls within fixture designs without significant cost surplus making the energy efficient gap between traditional light sources and LED based products extend significantly.
Of course, LED emitter technology will continue to be enhanced but this is now a secondary concern as focus shifts to high CRI LED products and lower cost systems.

Triple Bridge Gateway, New York City, USA.
Lighting Design: LENI SCHWENDINGER LIGHT PROJECTS Architect: PKSP
Leni Schwendinger has helped to transform a desolate area into a destination.
After more than ten years of community planning, design and construction, the bus ramps above Ninth Avenue at 40th Street have been transformed into an infrastructural public-art illumination installation that is delighting residents, visitors, passersby and motorists. Created in collaboration with the Port Authority of New
York and New Jersey (PANYNJ) by the design team of PKSB Architects and Leni Schwendinger Light Projects (LSLP), a formerly desolate stretch of Hell’s Kitchen roadway - shadowed by exposed steel and concrete overpasses - now shimmers with colour-infused light.
Notes lighting artist and designer Leni Schwendinger: “Instead of a place to rush through, our team has created a destination - a dynamic urban oasis for the eye and a visual landmark for the community.”
In 1994, Community Board #4 convened the Triple Bridge Task Force. Leni Schwendinger joined in this volunteer effort to solicit neighbourhood input and create design guidelines for aesthetic renovation of the bus ramps. In collaboration with the PKSB team, Leni Schwendinger Light Projects LTD won the PANYNJ-invited competition to design architectural improvements to the overpasses. Recalls PKSB lead principal Henry Stolzman: “We saw this project as a rare opportunity to celebrate infrastructure and mass transportation – transforming both into art and architecture.”
As the job grew in scope, facades on both the west and east side of the street were incorporated - including replacement with titanium panels of the terminal’s brick façade, creating a new entry marquee and opening commercial storefronts to enliven the streetscape.
The design process for Triple Bridge Gateway began in 1996. A series of mock-ups and installations continued from 2001 through 2008. The design choices - metals, lighting and color pattern - were conceived as emphasis for the bridges’ I-beam engineered structure. A chain-link containment system wraps the sides and underside of each ramp. This highly-detailed stainless-steel metal mesh works to reflect and diffuse light, as well as providing full-time maintenance access.
The lighting fixtures were selected for their capacity to withstand vibration and extreme weather conditions. Unique mountings were designed to achieve site-specific effects from industrial fixtures. Multiple light sources illuminate the bridge structure and the area under the bridges without interfering with ramp-roadway lighting.
Linear fluorescents emphasise the I-beam webs and bolted plates. Metal-halide CSI sources graze the mesh scrim, and wallpacks wash the bridge coffers with light.
A sculptural addition creates ‘a luminous room’. Pendant-mounted, high-polish, adjustable reflector panels pierce the scrim. Metal-halide light sources on the east and west walls of the underpass focus onto the panels that, in turn, cast reflected light patterns onto the street. The reflections unify the existing lines and spaces of the bridges, and accentuate movement and animation as cars pass underneath.
A computer-sequenced illumination scheme brings this urban sculpture to life with a weekly rotating schedule of visual compositions:
* Chambers of Colour - This formal composition focuses on the beam structure and corner shapes.
* Spectacle - A bright and bold composition.
* Reflections - Creates a connection of the street and the bridges’ underside through volumes of reflected light on the roadbed.

1.The EVGA Interview™ Display
2.NEC Curved Monitor
3.iView (experimental)
1.The EVGA Interview™ Display is redefining today’s face to face business interaction. With two displays capable of 1440×900 resolution, along with a 1.3 megapixel webcam and three port USB Hub, the EVGA Interview™ Dual Monitor System is not just another display.
The innovation does not stop there however. Both displays are capable of being rotated independently vertically and horizontally. When the display is flipped 180 degrees vertically, the screen intelligently flips so you can effectively share documents, images, and files with ease. This is the ideal monitor for anyone and everyone who communicates face to face.
Now when sharing information with friends, colleagues or employees, never again will you need to worry about poor viewing angles, knocking over items on your desk as you attempt to rotate your existing display or huddling around a single monitor. The displays rotate smoothly, and auto-flip the image without interruptions, even outside of the operating system!
Of course more displays mean more desktop space, and more desktop space means improved productivity. The two 1440×900 resolution displays can be set up as a clone (same image on both), or a span (extended desktop mode) with a supported graphics card. The revolutionary EVGA Interview™ Display will change the way you interact on a daily basis!
Graphics and multimedia analyst, Dr. Jon Peddie of Jon Peddie Research did a multi-monitor usage study and found an increase in productivity from 50 percent or more. “EVGA now enables in a single system what used to be called a ‘partners’ desk, traditionally facilitating teamwork between two executives while facing each other. Now users can flip the EVGA monitor over and both see the same thing. Doctors can use it in a patient-doctor relationship for reviewing X-rays with patients, teachers can use it for one-on-one tutoring, engineers can use it where they want to have a collaborative discussion on a design…and you can use it yourself for having more screen real estate because the more you can see - the more you can do.”

2.NEC Curved Monitor
NEC was showing off their curved monitor model CRVD-42DWX+ at CES 2008. It’s a 42-inch 2880×900 resolution 32:10 aspect-ratio 10000:1 contrast-ratio LED-backlit DLP display with a 0.02ms response time – great for 3-D gaming and widescreen & immersive apps. Same (?) as the Alienware Curved display also seen at CES…it’s made by the same folks, namely little-known ODM Ostendo Technologies Inc.
CRVD Technology
CRVD. Pronounced “curved.”
CRVD is Ostendo’s revolutionary new scalable technology that allows us to build curved-screen displays that offer unparalleled performance and immersion. The CRVD’s smooth curvature along with its vivid LED colors and blazing fast response time draw the user in and create an experience unlike that of any other monitor.
Vivid LED colors.
The CRVD uses the latest LED technology to deliver bright, accurate colors that are excellent for graphics and video work, or just to impress.
Blazing fast.
The CRVD has a blistering fast response time of less than .02 milliseconds, so there’s no ghosting in moving images and animation.
No special hardware needed.
CRVD displays work with existing graphics cards and games, so there is no need for special hardware or software. Check the compatibility list for further details.
The CRVD’s seamless curved screen engages 75% of the Human Visual System (HVS) peripheral vision, creating an unmatched immersive viewing experience. Whether it’s work or play, prepare to be engrossed.
Be more productive.
Curved screens offer additional productivity benefits above and beyond what flat monitors can offer. Research has shown that screen curvature increases productivity and reduces frustration when compared to multiple flat monitors.1
Improved ergonomics.
In multi-monitor usage, eye strain is often experienced because the focal distance varies across the displays. The CRVD eliminates eye fatigue because the screen is curved and the user’s focal distance remains constant across the screen.
With its roomy 2880-by-900 resolution, the CRVD will expand your desktop and give you extra space to be more productive. In fact, research has shown that wide desktops improve productivity more than 30% compared to a single monitor.2
See what you’ve been missing.
The CRVD’s ultra-wide 32:10 aspect ratio is 180% wider than 16:9 displays and 240% wider than 4:3, letting you see more of what’s important.
Like having two monitors in one.
The CRVD has all the benefits of multiple monitors without all the hassles. Say goodbye to disjointed desktops, split windows, multiple input cables, and that unsightly gap between monitors.

3.iVIEW
The iView curved monitor, designed by Nuno Teixeira, is both compelling and definitely not post-iconic…a kind of stretched and curved double iMac all-in-one desktop computer.
The LCD iView, as it’s officially called, is unfortunately just a concept and so not many details are available. The iView has a curved panoramic double LCD screen on the front and a smaller one on the back to benefit your colleagues. It has two video cameras, one in front & the other at the back with which to monitor those self same ‘colleagues’. Bluetooth also.
…nicely done…the iView dates to Feb 2007 & was perhaps the inspiration for the NEC/Alienware curved monitors that cropped up in CES 2008.
iView – from Nuno Teixeira’s Portfolio on Behance
—Concept year: 2/2007
The next step in LCD for professionals “the LCD iView” the first screen with two distinctive characteristics: a double panoramic screen with a unique curvature accompanying the natural eye curvature and movement.
Eliminate the use of two screens to achieve a larger work area. The use of dual screen, strategically put together side by side, originates areas where the visibility is hindered, not only by the proximity, but by the high perspective created by the curve-free plans, as well. With the iView you will get no undesired reflections, remarkably increased working flow and with the presence of all the commands and working plans in one big area, you can now drag them around or zoom them in or out, without any of the usual unnecessary physical interruptions or adjustments.
Get “another” view of you project. The large double screen iView comprises in its back another practical innovation - an extra LCD - extremely useful for both colleges and assistants. It allows them to follow your work in progress, without any effort, which instantly increases the creative exchange.
Other Characteristics:

Wireless, it only uses electric cable
Two web-cams, one at the front and another at the back.

Solar forest charging station for electric vehicles
Designer neville mars has developed an electric vehicle charging station that takes
the form of an evergreen glade of solar trees. the photovoltaic grove serves a dual function,
acting as a go to source for clean renewable energy while providing a shady spot for cars
to park as they charge.
aspects of urban life are caused by cars, for both driver and the city itself. Large sweltering expanses of tarmac in cities contribute heavily to the urban heat island effect, whilst cars also become unbearably hot in summer sitting in these urban deserts.
Optimizing the heliostatic photovoltaic panels ultimately resulted in their leaflike shape. Although never intentionally conceived to mimic the form of a tree, the panels rotate to follow the path of the sun throughout the day – much like sunflowers – absorbing light whilst also providing optimal shading for cars. Although all parked cars can benefit from shading, electric vehicles can directly charge their batteries by plugging into the ‘solar trees.’
Solar Tree is unique among anti-auto pollution designs in that it empathizes with the anthropomorphized automobile, but particularly with the electric car, providing a place for overworked, spent cars to regain their lost torque, to relax beneath the trees, to gain back their juice in an optimal stress-free environment.
