The EYE-PxP alignment tool features a comprehensive toolset to enable image correction for single- or multi-channel display systems. Developed for devices requiring colour and brightness correction, the toolset also provides colour shading, alpha masks and pixel-accurate blending, among other features.
Based around an easy-to-use GUI that provides straightforward configuration for one or multiple channels, the EYE-PxP can be used with visual display solutions from a wide range of manufacturers, including eyevis itself. Users can upload an individual LUT (LookUpTable) for each colour, while a shading map with independent transparency information for red, green and blue for each pixel can also be incorporated into operations. The ‘resolutionpassthrough’ technology allows easy integration into any system environment without the need to configure the desired resolution, with a DDC-EDID emulation feature among the other key aspects of the EYE-PxP.
Any setting and parameter can be permanently stored on the device, while the input and output is a single link DVI-D for resolutions up to WUXGA (1920×1200 @ 60Hz) or 2k (2048×1080 @ 60Hz).
Hans-Günther Nusseck from eyevis’s R&D department told IE: “The simple control and handling of the device allow for simple integration into existing or new systems. The device enables corrections of colour and brightness of displays or projectors without major interference in the existing infrastructure. The open interface architecture provides the possibility to integrate almost any calibration methods or alignment systems. For the growing range of products on the display market, the eyevis EYE-PxP provides a device-independent solution for colour and brightness corrections.”
The Reutlingen-based manufacturer has also announced details of the EYE-EDID-SIM-DVI emulators, which emulate the selected/programmed EDID for the attached PC to enable continuous video output - even if the attached display is disconnected or powered down. Allowing the user to set up operation for any DVI output resolution - whether or not the device supports this resolution or not -the EDID emulators work passively and do not use presets in conjunction with a switch. For uploading or changing the emulated EDID, users will require the EYE-DDC programmer.

Westminster Academy, London, England.
Martin Lupton and Luke Smith-Wightman of BDP Lighting explain the art of lighting design in school environments. using their work at Westminster Academy as a case study, they emphasise the important role of daylight, the guidelines associated with it and the need to consider electric light as an holistic element of the architecture and overall visual environment.
The current UK government is a significant way along the road of its plans to invest in the order of £2 billion in building and refurbishing schools. This offers the people who are involved in their design a unique, once-in-a-lifetime opportunity. Schools that are performing poorly or schools that are housed in aged decrepit buildings are being identified and re-built. Many of the UK’s schools buildings are between 50 and 100 years old and it is likely that this wave of new schools will stand for the same amount of time. In 50 years time education may be delivered in a completely different way so this could be the last opportunity many of us have to design the lighting for a school building.
The City Academies programme has seen new schools designed and completed by several prominent architects including Sir Norman Foster and Wilkinson Eyre amongst others. When the Government began this programme it was on the basis that they firmly believed that better designed environments will encourage more positive behaviour and improved academic performance.
As lighting designers, we are part of a growing awareness of the power of light and its role in design and usability of spaces and places. Our craft is widely recognised in environments where the commercial cost of design and high quality luminaires are seen as valuable investments. In retail spaces the link between brand quality and customer spend is well established – lighting can play a key role in supporting the brand image.
In commercial offices the value of lighting to the workforce is starting to be understood but the power of lighting in creating the right impression in the reception is fully accepted. In urban spaces the links between lighting and crime, the perception of safety and the creation of a night-time economy are completely accepted. In fact, lighting designers are employed and allowed to practise their art and science where there is perceived commercial value. But what about spaces where there is social value but limited commercial value?
It could be argued that urban lighting embraces some social elements and has positive benefit on the community it serves. In schools and hospitals, two of the most socially important spaces, the lighting design is, more often than not, left to the electrical engineer or even electrical contractor.
Lighting Design: BDP Architect: AHMMWith daylight as the primary source of light, the artificial light needs to be developed to support this strategy and maximise the benefits. The opportunities to save energy and reduce maintenance must be embraced with automatic control. However, it must not be forgotten that most schools have a single in-house maintenance contractor – the caretaker – and his responsibilities will be both varied and numerous.
Maintenance must be as straight forward as possible. If a school can be designed with a minimum number of lamp types, that respond to daylight and operate only when required, then it will have a long life and be simple to maintain.
Schools are one of the most socially important spaces that we as designers, architects and engineers can be involved in. These are the places where the thoughts and behaviour of our children are developed and moulded. Lighting, both electric and natural, has a significant role to play in the quality of environment in a classroom. High levels of controlled daylight and good vertical illumination are the key design criteria for the creation of a successful classroom. However in the strive for innovation and creative design we must not forget the how these important buildings work, the length of time they are design to stand and the many different users that will inhabit and operate them.
Simplicity and robustness of operation is a fundamental requirement.
In many spaces we have come to realise that horizontal illuminance is a poor measure of design quality, and in schools in particular this is true.
Modern styles of kinaestic teaching rely on visual interaction between the students and teacher and therefore the visual focus is usually on the vertical rather than the horizontal. High levels of concentration are essential from the students and anything that can detract from this must be eliminated. It is essential that all lighting – natural and electric – is controlled and delivered into the space in a comfortable way.
As the physiological and biological effects of daylight become more widely understood and appreciated the reasons and justifications for high levels of daylight in schools can be enforced. Recent research indicates that high levels of daylight are a very positive contributor to academic performance and behaviour of students. Research in the USA, by the Pacific Gas and Energy Company, showed that students in classrooms with the highest daylight factors (in the order of 10%) progressed up to 20% faster on maths test and up to 26% faster on reading tests. The results of similar research in Sweden showed significant correlation between behaviour and daylight. In broad terms this research has also shown that student who attend “day lit” schools outperformed students from “none day lit schools” by 7%-14%.

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.
Geoff Archenhold is an adviser to the UK Government on LED technology and helps LED companies raise investment from the finance community. He is an investor in an LED driver company and an LED fixture company, a Lighting Energy Consultancy and euroLEDs Events LLP.

Santa Cristina della Fondazza
LED Projects Italy
“This is one of the first examples of monumental ilumination with LED Technology”. Ferruccio Bigi, Bigi + Gregoli.
Santa Cristina della Fondazza is one of the most beautiful churches in the city of Bologna: an 800 year old gem.
Rebuilt in 1602, at the end of its single nave it has a presbytery, thanks to which the architectural structure has wonderful acoustics, and sound is propagated with extraordinary clarity. The church is also used all year as an auditorium and hosts extremely valuable works of art.
During a recent restoration, the interior lighting was also revolutionised, adopting a scheme based almost exclusively on LED fixtures. With this unusual lighting solution for a church, Bigi+Gregoli studio managed to meet different indispensable requirements: highlighting the unique artistic heritage, creating atmospheres suited to the concert performances, accentuating the cultural role of a consecrated building and keeping its sacredness intact.
After careful selection, SGM LED fittings (supplied by Volume srl) were chosen: 24 Palco 5, 1 Ribalta and 38 Genio Mobile, plus 4 Giotto Wash moving head units and a Pilot 3000 console, used to program and control all the lights.
The LED fixtures were used because they are free from ultraviolet rays that could damage the works of art; its colour temperature is adjustable, thanks to the RGB colour mixing system, with which the tones most suited to the atmosphere can be set according to the colour and form of each painting, statue or architectural element.
The fixtures are mounted along the perimeter cornice, at a height of eleven metres, with a low-impact installation involving absolutely no masonry work. Divided into groups, they are concentrated on various sectors of the church, towards which they are aimed (the main altar, the organ, the statues in the niches, the nave environment, etc.) and they create looks studied according to the varying requirements of the auditorium. The system guarantees minimum consumption and running costs compared to those of any other light source.
