LEDs and Lighting Keynote:
The Transition to Solid State Lighting Lighting – both commercial and residential— is a significant consumer of energy and therefore responsible for significant greenhouse gas emissions. The problem starts with more and more light sources worldwide, but the low efficiency of incandescent bulbs compounds the problem. Fluorescent bulbs are providing short term relief. But in the long term, solid state lighting is an even better solution. This address will dig into the obstacles to and benefits of solid state lighting. Attendees will learn about needed advancements in the LED and get a projection of when solid state lighting becomes cost effective in a broader range of applications. Moreover, discover the impact that solid state lighting can make on long term energy requirements. About the speaker: Inês Lima Azevedo is a research engineer at the Climate Decision Making Center from the Department of Engineering and Public Policy at Carnegie Mellon University. Her research focuses on sustainable energy systems and climate change policy, with particular emphasis on energy efficiency related issues. Her recent work focuses on national and regional assessments of the energy savings and the economic costs and benefits of energy efficiency in the US residential sector under several policy options. She has also recently performed an extensive review and assessment of the transition to solid-state lighting in general illumination systems in the US, as well as a benchmark and econometric assessment of US and EU residential electricity consumption. Over the course of the last two years, she was involved in consultant/research assistance in projects for the Lawrence Berkeley National Laboratory and for Resources for the Future. She holds a PhD in Engineering and Public Policy from Carnegie Mellon University, an MSc on Engineering Policy and Management of Technology and BSc+MSc in Environmental Engineering from IST Portugal. Inside the LED: Understand the Specifications, Characteristics,

120 Hz Ripple: Is there an Effect on Vision and LED Lifetime? See What Your Peers Chatted About Is there a lifetime effect when pulse-width modulating or allowing high ripple at relatively low frequencies, such as 120 Hz? Does LED packaging matter? What studies have been completed? Are there visual effects of 120 Hz ripple? What about if fast motion is involved, such as in street lighting applications? See what your fellow engineers chatted about in this discussion on saving power with the latest LED drivers. Moderator: Joe DeNicholas, Lighting Business Unit Director, National Semiconductor Maximizing LED Performance and Efficiency
In LED-based designs, maximizing brightness and lifetime while minimizing power and temperature are conflicting requirements. Like many design challenges, LED drive circuits must meet goals that run counter to the implications in the circuit design. For instance, applications need maximum brightness, but maximum brightness means high power and shorter LED life. Applications need long life, but LEDs generate heat and heat both degrades operational characteristics such as brightness and color over time and shortens the product life. Experts will discuss circuit designs that deliver required optical performance while minimizing the impacts on power consumption and temperature.

See What Your Peers Chatted About Are you familiar with traditional LED design or are you using LEDs in new applications for you products? What are the key design factors when designing with LEDs? If you’re new to using LEDs to replace traditional light sources what are the difference in design and implementation? Will LEDs replace your current solution, if so, what are the design challenges that your face? Moderator: Steve Klesker, North American Sales & Marketing Manager LEDs, Avago Scheduled Chat:
LEDs are Suitable for Any Lighting Application: Fact or Fiction See What Your Peers Chatted About We often hear about the myriad uses of LEDs. Can they possibly be suitable for as many applications are we're hearing? In this chat session, we'll look at exactly which applications are best suited for LEDs, and we'll ask some of the designers that have actually implemented these devices how their experience was. That'll help us compile a list of best practices for designers interested in tackling such a project. Moderator: Richard Nass, Director of Content, TechInsights Sponsored Presentation:
High Efficiency Drivers for High Efficacy LED Lighting Recently high brightness light emitting diodes (HB LEDs) have increased in luminous efficacy (lumens/watts), color quality, stability and reliability. At the same time manufacturing improvements are bringing down the cost of the HB LEDs. The improvement in performance and decrease in cost continue in time on a curve known as Haitz’ Law. In combination with the advantages of “instant on” and lack of mercury or lead in its manufacturing process HB LEDs have displaced filament and gas discharge as the future of lighting technology. This webinar will present some basics of LEDs: LED construction and packages, electrical characteristics, thermal characteristics, lumens maintenance, color rendering, efficacy, basic driving architectures and dimming techniques. The webinar will then discuss the use of HB LEDs in luminaries and the regional standards affecting them. The challenges of dimming input, especially those exemplified by phase cut TRIAC dimmers will be discussed. Finally LED lighting drivers EVMs and reference designs for residential, commercial and outdoor applications will be discussed. Presenter: Peter DI Maso, Product Marketing Manager, Lighting Power Products, About the Presenter: LED Applications: Opportunities Drive Advancements in
Design and Components LEDs are finding widespread use in both display backlighting and illumination applications because of the tremendous advantage they offer in terms of lifecycle costs and energy consumption. It’s imperative that designers understand the advantages that LEDs bring and how they can really decide if LEDs fit in their application. Potential applications could be, but aren’t limited to, illumination in the home, auto, commercial, industrial, displays (backlighting), LED displays (OLEDs), and indicators.

How do you optimizing the tradeoffs between LED Count, Light Output, and Efficacy? See What Your Peers Chatted About We want to hear what you think the trade offs are when designing a solid state lighting luminaire. As you know tradeoffs must be made between LED count, light output, and efficacy for meeting target performance specifications. We want to hear what your calculation methods are and which tools you use for making these design decisions. Moderator: Patrick Durand, Worldwide Technical Director for Future Lighting Solutions Scheduled Chat:
How Do You Deal with Potential LED Failure in Your Design? LEDs are supposed to last forever, right? Maybe not forever, but for a long time. But that's only if you design the lighting subsystem properly. During this chat, we'll ask some of the attendees to share their experiences in designing the LED-based lighting subsystems, and help other designers avoid the potential pitfalls that could result in failure. Moderator: Bill Schweber, EE Times Site Editor, Planet Analog and RF DesignLine The LED Driver: It’s More Than Just a Power-Supply IC
The LED-driver IC is a power-supply IC, but optimized for sourcing of current. How does it differ from a conventional voltage-source power-supply IC? What features make a good LED driver IC? Which specifications are critical for the LED-driver application, and which are not so critical? What external components are needed, and why? How does the LED topology being driven (series, parallel, combination) affect the needed capabilities and characteristics of the driver?
