LEDs, Jules Verne and the Third Eye
Cary Eskow, Director of Technology
Avnet
8:15am
Today it is generally well-accepted that the primary motivation for implementing Solid State Lighting (SSL) solutions is improved energy efficiency. Unfortunately SSL cost barriers remain high, and in many cases this is slowing commercial adoption and thus delaying the attendant “Green ROI”. What other market forces will accelerate demand, and overcome cost issues? One of them may be the psycho-physiological impact of various wavelengths of light— ranging from influencing circadian rhythm to enhancing concentration and increasing the visual appeal of food and merchandise. Dynamic control of light composition is a unique, and perhaps underexploited, characteristic of properly designed high-brightness LED (HBLED) systems. Consumers and commercial users of SSL may place enough value on these HBLED-related benefits to overcome cost objections and thus accelerate the Green Revolution.
Mr. Eskow’s presentation will provide a survey of several interesting light-related psycho-physiological findings, as well as creative means to leverage them as extended features/benefits in new Solid State Lighting products.
Emerging Applications for Energy Harvesting
Tony Armstrong, Director of Product marketing
Linear Technology Corporation
9:30am
Everywhere you look, engineers are coming up with new and innovative ways to harness non-traditional energy sources so that we can reduce greenhouse gas emissions save the planet. These energy sources are all around us and include heat generated from a thermoelectric generator or thermopile, vibration (or strain) energy from a Piezo element, photovoltaic energy from sunlight or indoor lighting and even galvanic energy from moisture. The common term applied to these practices is energy harvesting and it allows us to do things we have never done before. Tony Armstrong of Linear Technology Corporation will present examples of emerging applications where energy harvesting can be of practical use. Tony will review and discuss several products including their power conversion needs in order to be implemented in a commercial environment.
New Choices for Energy Efficient Power Design
Stephen Oliver, Vice-President, V*I Chip Division
Vicor Corporation
10:45am
New architectures enable different approaches to power conversion that offer significant energy efficiency advantages for green technology. For datacenters, direct 48 V to 1.x V conversion, coupled with new control techniques, allows and increase in system efficiency while meeting all the requirements of the new VR12 specification.
This presentation will compare traditional approaches and new architecture examples of high density, high efficiency circuits for datacenters, automated test equipment, lighting/displays, and more.
Towards an Energy-Efficient California Economy: Policy and Actions
Chris Scruton, Technical Lead
California Energy Commission
Keynote Lunch Presentation
11:45am
For over 30 years California has pursued energy efficiency through building codes, appliance standards, and utility programs. With the twin threats of energy security and global warming these efforts have intensified. California's policy goals now include capping greenhouse gas emissions at 1990 levels, determined to be equivalent to 427 million metric tons CO2 annually, by the year 2020. Complementary goals laid out by the California Public Utility Commission in the Strategic Plan of 2008 include all new residential buildings to be zero net energy by 2020 and all new commercial buildings to be zero net energy by 2030. This talk will explore what California policy makers, citizens and industries are doing to meet these ambitious goals.
LED Lighting - Optimized Design for Dimmable Applications
Michael Pena, Senior Director, Technical Support & Applications
NXP Semiconductors
1:00pm
Recent years have seen a steady improvement in the performance of light emitting diodes (LEDs) enabling new applications in lighting. Key benefits of proper LED fixture design include flicker-free dimming, superior energy savings, and increased lifetime. However, these benefits can only be realized if the complete fixture design is optimized for all aspects; thermal, optical, and electronic. This presentation reviews the design considerations needed to optimize the electronic design of a LED lighting system.
Microcontrollers: The Enabling Technology Behind Smart Grid Applications
Tim Dry, Senior Marketing Manager
Renesas Electronics America, Inc.
2:15pm
To manage our energy consumption more effectively, it is critical that we understand how that energy is being consumed. While smart meter technology is very useful, keeping up with the diverse and changing communication technologies, increasing requirements and emerging applications can be challenging. An effective smart energy system requires both the intelligence to gather, process and communicate data, and the flexibility to accommodate current and future technologies.
This presentation will examine the use of specialized MCUs to more efficiently manage smart energy systems within the home area network (HAN). MCUs can provide the intelligence to monitor real-time applications and adjust as needed for greater efficiency, and communicate the information via ZigBee and powerline communications (PLC) for seamless transitions between smart home systems, including smart meters, LED lighting, solar panels and appliances.
Enabling Easy Development of Google PowerMeter Designs for Smart Energy Monitoring
Michael Ballard, Manager, Home Appliance Solutions Group
Microchip Technology Inc.
3:30pm
Google PowerMeter is a free energy monitoring tool that helps consumers save energy and money. Using energy information provided by utility smart meters and energy monitoring devices, Google PowerMeter enables consumers to view their home's energy consumption from anywhere online through a secure, Web-based iGoogle™ gadget. As a Strategic Partner, Microchip incorporated the recently announced Google PowerMeter API to create a Reference Implementation, which makes it much easier to develop products that are compatible with Google PowerMeter. Microchip's Reference Implementation demonstrates the device's activation, data transmission and status messages using readily available Microchip development tools which can be used as a template for developers' own designs. This presentation will help you to better understand the Google PowerMeter software tool as well as Microchip’s Reference Implementation of the Google PowerMeter API.
