MONDAY, 27 SEPTEMBER 2010 Workshop A – Standards for LED Lighting: What’s the Current Status and Where are the Gaps? Standards are playing an essential role in the growth of the LED lighting market and the rate of adoption of LED lighting in various applications. Without standards, performance comparisons can be difficult or impossible, and specifications cannot be traced to a meaningful reference. This can make customers and specifiers uneasy about using LED lighting for their projects. With standards in place, such issues can be alleviated. Various standards have already been issued, relating to both performance and safety of LED-containing products. This Workshop reviews the existing standards that are in place both internationally and in North America, and looks at the ongoing work to create new standards. Also discussed will be the different photometric measurements that are called for by various standards. International standards for LED products Andreas Scholtz, Standardization Officer, OSRAM GmbH Test and measurement of high power LEDs Eric Schwabedissen , Sales Engineer , Instrument Systems Introduction to the new requirements of UL 8750 Albert van der Veen, Project Engineer, UL International (Netherlands) BV, The Netherlands Safety standards for LED lighting Lars E H Norén, Senior Technical Manager, Intertek Luminaire Performance Standards for North American Certification Programs James Walker, Manager – Testing Services, Lighting Sciences Inc, Workshop B – Building the Perfect Luminaire: Essential Considerations when Designing Effective LED Lighting Due to the nature of LED light sources, the design of high-quality LED-based lighting fixtures requires specific design competences. OEMs and producers of LED-based luminaires must decide whether they have sufficient in-house expertise and resources, or if they need to select a partner with the appropriate knowledge in LEDs, electronics and associated components. These and other considerations are discussed in the “CELMA Guide for OEMs and Producer of LED-Based Luminaires,” which will be presented during the Workshop. Further presentations will then focus in more detail on three specific technical areas that are all essential parts of a well-designed LED-based luminaire, namely optics, drivers and thermal management.

From mobile phones to cars – there is hardly any field in which semiconductor solutions are not making real inroads. And there’s a very good reason for this – these new technologies are long-lasting and efficient. For the lighting industry, this development is a major opportunity but it also raises questions. How quickly will LEDs replace the classic technologies? What conditions need to be created in general so that the LED market can stand on its own two feet? What technical challenges do we have to meet? And how will the next generation of light, the OLED, influence this development? In his keynote address, Martin Goetzeler, CEO of OSRAM, presents the latest examples of applications, demonstrates the major trends in the industry and ventures a forecast. To the future of light. Promoting Quality LED Lighting within the European Lighting Industry The main focus of the European Lighting industry, represented by ELC (Lightsources) and CELMA (Luminaires and their components), is to assure that LED lighting in Europe brings an improvement of the Lighting Quality as well as a further increase of the Energy Efficiency of the lighting system. In this key-note speech running activities and the views of the industry in the fields of standardisation, minimum performance criteria, market surveillance, quality labelling, etc. will be explained.

Session 1 Time: 08:30 – 10:00 Room: Congress Center C HB LEDs and LED Lighting Market Overview and Forecast Vrinda Bhandarkar, Analyst, LED Practice, Strategies Unlimited, USA This presentation will provide a review and update of the market developments in HB LEDs. Top level market growth trends will be discussed, as well as developments in lighting. In addition, it will provide a review of the trends in the HB LED industry. With rapid advances in the efficacy of LED light sources, their application in the general illumination applications is well underway. While the LED luminaires and replacement lamps have a high initial cost, LEDs in lighting have become feasible in applications that are difficult to maintain, and in hard-to-reach places where the long life and low maintenance costs of LEDs provide competitive cost of ownership. The LED lighting market is expected to continue its strong growth, aided by commercial availability of brighter and cheaper HB-LEDs. Heightened awareness about energy efficiency and the environmental cost of using energy has created conditions favorable to the growth of LED lighting market. The presentation will include a review of the market, and technology trends as they affect the emerging applications for LEDs in lighting. It will also discuss the LED lighting market segmentation by application and market trends for the application segments, with a forecast through 2014. Lighting designers and specifiers; how are their requirements being met by LED lighting Mike Simpson, Technical & Design Director, Philips Lighting, UK The UK has a well-established lighting specification market with global reach. Like UK architects, specifiers seek to offer leading-edge technology to their customers. LEDs are transforming their offer but at the same time introducing new challenges. How do you design with such a fast-moving technology? How can you specify a product that will have changed in performance before it is even installed? Can we believe the performance data we are presented with? These are just some of the questions that have had to be addressed. By bringing together the leading professional and trade organizations, the UK has addressed many of these questions so that there is a growing confidence in specifying LED products. Alongside this can be seen the switch-over from conventional light sources to LED solutions by application sector, with the Holy Grail of commercial lighting just around the corner. The paper will look at how LED lighting is meeting the aspirations of designers and transforming the global lighting market. Mike Simpson is a past president of CIBSE.

Session 2 Time: 10:30 – 12:00 Room: Congress Center C The Chinese Strategies on SSL Technology and Industry Ling Wu, SSL is a disruptive technology, it will change our lives as well as the international lighting industry. To cultivating emerging strategic industry, implementing energy and environment stragegy and ensuring sustainable economic development, China is going to pay great efforts to develop SSL industry. This presentation will analyze the importance of SSL for China, introduce the current status and challenges of SSL industry in China, as well as the China strategies. Markus Klein, Senior Director & General Manager Solid State Lighting, OSRAM Opto Semiconductors GmbH, Germany LEDs are already on their way to penetrate most lighting applications, and their unique benefits are contributing to many new applications in the lighting area. Currently in development, OLED technology will soon enable further design options and greater flexibility. Two-dimensional OLED light sources will enable extremely thin and flexible light-emitting surfaces in the future. Neo-design, beautification and architainment (architecture + entertainment) will be the next developments. The combination of spot-lit sources and two-dimensional lighting may change the way we use light. This will all be feasible with a fraction of the energy we need today to produce artificial light. Lighting design, using both LED and OLED technologies, will be completely redefined and fundamentally change our everyday lives in the coming years.

Session 3 Time: 13:30 – 15:00 Room: Congress Center C Driving for greater efficiency and performance From the smallest lamp retrofit through to high-power street lighting, the LED driver is a key component in achieving high system reliability and efficiency. Frequently ignored in the discussion of LED lighting, driver technology and control techniques are continuing to develop rapidly. This presentation will demonstrate how LED drivers can remove barriers to adoption and unlock the true promise and potential of LED lighting, while improving the overall value proposition. Topics to be explored include: · Bad drivers - pull over · You can have it all - regardless of power level and application · Shrinking the envelope - more power, more performance - less space · How low can you go ? - dimming techniques unwrapped · You can do it ! - Intelligent solutions to improve your life, and grow your business Although a technical subject, the aim of the presentation is to appeal to a wide audience with a minimum of graphs, equations and circuit diagrams - instead we will explore real life examples, lessons learned and show how drivers can create inspirational product solutions for a wide range of lighting applications. There are very high expectations for LED street lamps, which should significantly reduce operating costs while also improving the quality of lighting. To compete with state-of-the-art products without LEDs on an economic basis, the development of LED street lamps has to reduce costs in manufacturing, reduce installation costs and minimize the energy consumption of the installed product. There is a vast number of LED street-lighting products on the market, most of which do not meet the required standards or which consume more energy than products without LEDs. Existing lamp technologies are often more efficient, cheaper and come in lumen packages suitable for street lighting. Even so, well-engineered LED street lamps can compete with other lamp techniques on an economic base. A key to this potential is the fact that it is easier to develop highly-efficient optics for LEDs than for other lamps. Excellent optics for LEDs can redirect 80% or more of the LED’s light into the target area on the street. The quality of the optical engineering has critical influence on the overall system. High optical efficiency leads to low energy consumption. Other measures of quality, like uniformity, low glare and separation of posts are controlled by the optics. Efficient optics lead to a lower required number of LEDs and therefore reduced heat sinking. A robust optical approach helps to tolerate variations between the single LEDs. The paper shows the development of a 29W street lamp as case study.

AC LED – The Infrastructure Solution Conventional lighting wastes energy and has a relatively short operational life, but it is simple and has a very low capital cost. LED lighting has matured as a technology to the point where it can successfully replace many conventional light sources, however it is complex and has a high capital cost. |

Session 4 Time: 15:30 – 17:00 Room: Congress Center C As Strong as the Weakest Link: Reliability from the LED System Perspective Rudi Hechfellner, Director of Applications, Philips Lumileds Lighting Company, USA Overall system reliability is only as good as the weakest link. While the LED supplier can quantify the reliability of the LED, the probability of failure of the rest of the LED system also needs to be quantified. This paper will discuss methodology for evaluating how arrays of LEDs behave over time, and how LED luminaire manufacturers can confidently make business decisions such as warranty commitments. LED Industry Shifting from Technology-Driven to Application-Driven Market Tom van den Bussche, European Marketing Director, Bridgelux Inc, USA The LED market is reaching the stage in 2010 where single LED array platforms are able to provide standardized, future-proofed solutions to meet the majority of the standard lamp lighting ranges, along with the demands for proper lumen packages delivering the right CCT, CRI, color consistency and lumens-per-watt. This good-is-good-enough evolution will set in motion a shift in the character of the LED lighting market. This market is evolving from being purely a technology-driven market to an application-driven one, as this presentation will discuss. In 2010, LEDs will start their full integration as an excellent light source, moving into mainstream lighting while simultaneously adhering to traditional lighting selection criteria such as design, ease of installation and short payback times. |

Session 5 Time: 08:30 – 10:00 Room: Congress Center C How Many Governments Does It Take to Change a Light Bulb? The adoption of LED lighting technology has been happening, niche by niche, for the last 15 years, with vastly different results when comparing various geographical and political markets. This presentation will review 15 years of progress in the adoption of LED technology exploring barriers, accelerators and initiatives to drive adoption of energy-saving LED technologies. Topics will include:
Attendees will gain a valuable insight in to over 15 years experience of driving the adoption of LEDs in globally regulated markets. They will learn about the importance of value proposition, ROI and how this extends way beyond the obvious benefits of LED technology. And they will also gain an insight into many of the markets and applications in which LED has been successful and which applications could soon experience rapid growth with the correct government and regulatory intervention. The New Technology Landscape Of Lighting - From Challenges To Solutions Lighting is going through a radical transformation, driven by both various society needs and rapid progress of SSL technologies and micro/nanoelectronics. Starting from the major technology and business development trends of SSL, this talk will summarize the associated scientific and technological challenges, and present the so called “New technology landscape of lighting”, which is the seamless integration and combination of “More Illumination” (focusing on efficiency, cost, retrofit, miniaturization and revolution in form and fixture) with “More than Illumination” (focusing on new functionalities, intelligence and interaction management), aiming to create high value lighting systems and solutions (See figure below).This new technology landscape will have profound impact on not only future technology development, but also global lighting business landscape. The strategic research agenda associated with this new technology landscape will be also be highlighted. LED Backlighting: Utilizing BLU Technology for General Lighting Uwe Hock, Manager, Manager Lighting Business, Sharp Microelectronics Europe, Germany At the moment the share of LED-backlit TVs is small but is expected to grow rapidly in the next several years. Sharp is one of the leading LCD TV makers, with vertical integrated competence in LCD and LED technology. This presentation will start by analyzing the properties of LEDs that make these devices suitable for the construction of LCD TV backlights. The advantages of using LEDs in LCD TVs include sharper contrast, brilliant and natural colors, energy efficiency, small form-factor, uniform illumination and more. The presentation will then discuss how detailed knowledge of LED backlight technology can be utilized for general lighting applications. |

Session 6 Time: 10:30 – 12:00 Room: Congress Center C High Efficacy Linear Lighting Fixtures – Market Demand, Technical Trends, Competitive Technologies, Design Approaches and Manufacturer's Experience The talk will cover the design and manufacture of high efficacy linear lighting fixtures for the use in decorative and general lighting applications from low to high ingress protection requirements (IP68). Besides the market demand, technical trends and competitive technologies the manufacturers practical design approaches and daily experiences will be discussed. Despite the ongoing improvement in LED price and efficacy the market requires overall high efficacy and durable linear lighting fixtures at reasonable cost compared to other light sources. On the one hand products need to be designed to supply a maximum of light output, guaranteeing a high light quality (in terms of binning and CRI), long life time (>50.000hrs) and thus a low thermal load (Tj < 110 @ Ta = 50°C) on the LED light source. On the other hand the bill of material needs to be provide a sustainable basis for future LED improvements and to keep tooling and material cost at a minimum. The talk will try to provide advise how to handle this issues from a system approach. Modular Spot- and Down-Lights Beyond 1000 Lumens with Minimized Supply Chain Complexity Stefan Gianordoli, Group Leader LED Components, Ledon Lighting, Austria Down-lights and spots for retail, office and residential illumination are the playground for solid state lighting (SSL). Benchmark efficiency versus traditional light sources is achieved, and the SSL platform enables the replacement of compact fluorescent, HID and halogen light sources. Factors like color rendering, stability of color over time, zero color bin, well defined luminous flux packages and maintenance over lifetime are coming into focus. The paper discusses a modular approach to LED-systems starting from 500 lm up to more than 5000 lm. Based on the modular concept, logistic effort and supply chain complexity can be minimized, both on the customer and supplier side. Additional features like tunable white open a new playground for lighting designers. A new generation of intelligent light sources is achieved by smart combination software, hardware and LED technology. Impact of Video-Based LED Lighting in Architectural Projects Carl Rijsbrack, Director, Director Product & Solutions Management VLS, Barco, Belgium This presentation will attempt to answer a number of questions about the synergy between lighting and video by looking briefly at various applications and recent developments. It will then elaborate on the evolution towards a video-enabled “Creative Lighting” system. With reference to various projects, the presentation will show the impact of the implementation of LED lighting into the architectural market, such as land marking, image building and commercial value. The session will also expound the requirements for integrating LED lighting into buildings, for example project management, value chain, delivery process and customization, and seamless integration of the LED pixels into the architecture. |

Session 7 Time: 13:00 – 15:00 Development of LED Retrofits Moritz Engl, Head of Department - Development SSL Consumer Lighting Europe, OSRAM GmbH, Germany Although 40 W retrofit LED lamps are on the shelves now, much development has to be done to produce lamps that can replace 60W lamps or even brighter lamps. This paper will present an overview of retrofit lamps, looking at how they are constructed, where the limits are and what needs to be done to achieve even brighter lamps. The presentation will examine various examples, such as what is necessary for a 100-W lamp retrofit. Assumed is a A60 bulb with length 100 mm and diameter 62mm. With that shape, one can dissipate around 8 W heat while the temperature at the heatsink must be low enough for electronic components and LEDs. The luminous flux must be 1505 lm. This can be reached when the LEDs are having an efficiency is around 133lm/W in the steady state, equivalent to ~165 lm/W in the cool state at around 3000K. The wall plug efficiency is then at 116lm/W. 2010: The Year of the LED Module Andy Davies, Product General Manager LED Solutions EMEA, LED Solutions, EMEA, GE Lighting, UK As LED technology progresses ever further into the general lighting arena, there is a growing demand for modular luminaire systems where the LED technology can be replaced and upgraded. Experiences with variable quality integrated luminaires have led some lighting designers to only specify modular systems where the LEDs are replaceable, whilst many luminaire manufacturers are beginning to realise the investment cost of continued re-tooling to keep their product range current in such a dynamic industry. Industry dynamics such as this have led to 2010 being christened ‘the year of the LED module’. Already we have seen significant new product developments in this field by a number of the worlds largest lighting companies, as well as newer specialist LED manufacturers. We have also witnessed the establishment of a new organisation to standardise LED module interfaces. In this presentation the author examines the reasons for this industry trend, looks at some of the more significant product developments, and examines the dynamics leading the industry towards standardisation of modular systems. What it Takes to Bring 2.5 Million LED Lamps to Consumers’ Homes Martijn Dekker, CTO, Lemnis Lighting, The Netherlands To help accelerate the adoption by consumers of environmentally-friendly LED general lighting, a product launch, unique in its scale and impact, was carried out in the fall of 2009 in The Netherlands. In 4 weeks, the Dutch postcode lottery and the World Wildlife Fund distributed 2.5 million Pharox 6W dimmable LED retrofit lamps among their participants. This was combined with a massive media campaign under the banner “Wat LED-je?” (“What keeps you from moving to LED?”) with endorsement from media stars, entrepreneurs and the Dutch Ministry of Environment. This presentation looks behind the scene and discusses the specs of the product, and the key trade-offs in the product’s design and cost. It describes what it took to meet these specs in mass production for millions of units with a timescale of only one month. Also, it looks at the main contributors to spread in performance, such as lumen output, color point, power and dimmability. Finally, the presentation will discuss the key technical lessons and the feedback from the end-users. |
