Abstract

There are many different issues around intellectual property in the LED industry: every company needs to understand its own IP position. IP is not like other assets and it is important to understand how intangible assets differ from other, more familiar assets. Accurate IP inventories and IP landscape awareness, linkages between IP and business strategy, tracking of competitors' IP positions, value creation and maintenance through IP, valuation and exit strategies for IP portfolios  - these are just some of the primary considerations for LED companies in today's markets. Developing an appropriate and comprehensive IP strategy is an essential function for any company that wants to avoid IP problems and also to use its own IP as a strategic asset. The author's experience as the portfolio manager for Color Kinetics provides the basis for a look at modern IP management strategies, techniques, and tools.  There will be discussion about the ways that IP managers in LED lighting companies can deal with intangible assets, often inside companies where their tasks are complicated by a general lack of understanding about intangible assets. It is expected that this will be a highly interactive workshop where participants are encouraged to share their experiences in IP to the benefit of all attendees.

Workshop 3 - The Replacement Lamp Tear Down     

8:00-12:00    The Replacement Lamp Tear Down
Presenter:
Steve Paolini
CTO
NEXT Lighting

Abstract
A great way to learn about the status and trend of solid state lighting is to carefully take apart lamps and tubes and document the results. They are relatively inexpensive, readily available, and constantly updated. However, not everyone has the inclination or means to carry out the disassembly and measurement. This workshop will show the results of many products that have been opened up and measured. We will also provide a methodology and framework for the why and how to go about your own analysis. In general, we look at the electrical power input/output, the optical power output/loss, and the quality of the final lumen output.

About the Smart Lighting Engineering Research Center:                
The Smart Lighting Engineering Research Center (ERC), founded in 2008 by the National Science Foundation, performs research on advanced lighting systems enabled by advanced LED sources, light detection devices and interactive controls and light based communications systems.  Led by Rensselaer Polytechnic Institute with university partners at Boston University and the University of New Mexico, the Smart Lighting ERC is developing the advanced devices and engineering concepts required to enable future solid state lighting systems to deliver exactly the right light where and when it is needed.  Learn more at http://smartlighting.rpi.edu.

Efficient solid-state lighting has progressed to the point that it can replace most conventional illumination sources. New lighting system capabilities that include dynamic color tuning, new form factors, as well as the integration of video capability with illumination (synthetic windows) need to be evaluated with regard to human health and performance.  Solid-state lighting’s new capabilities and unique lighting properties offer tools for examining the psycho-physiological effects of light exposure on humans in health services, education and the workplace.  Along with new illumination capabilities,  control system strategies will also influence how people and lighting systems interact.  This workshop will examine how lighting affects human performance and well-being in settings as diverse as healthcare and education, particularly considering how solid-state lighting  could lead to innovations in lighting practice and research that save energy and improve our lives.

Jennifer Veitch
Senior Research Officer
National Research Council

Abstract
My colleagues and I have shown that better office lighting delivers benefits to individuals, their employers, and the environment. This research focused on the benefits of workstation dimming control and light distribution. SSL systems offer the potential to add individual or automatic color tuning of light source spectrum. We have begun to study these effects on office occupants, finding that there is a broad range of preferred light source spectra and a desire to have this feature. Innovative features that respect lighting quality principles will enhance the attractiveness of new lighting technologies, speeding uptake and achieving sustainability sooner.

William Witherspoon
Founder
Sky Factory

Abstract
Light, by virtue of its dynamical versatility and its ability to resolve into content laden image, is arguably the principal channel by which human beings receive information from their environment.  Further, because of our evolutionary reliance on vision, light-transmitted information receives high priority as data for the cogitative process that leads to perception. Consequently, light driven illusion, generated by solid state and video technologies, can be judiciously used as a powerful tool to modify the built environment and enliven genetically essential biophilic elements in the physiology and psychology of its human occupants.

Robert Casper
Professor, Div. of Reproductive Sciences, Univ. of Toronto, & Sr. Investigator,
Samuel Lunenfield Research Institute
Mount Sinai Hospital

Abstract
Rotating shiftwork involves recurrent disruption of normal circadian rhythms by nocturnal lighting. Low wavelengths in nocturnal light (440-480 nm) have the most pronounced disruptive effects on endocrine and clock gene rhythms, and ultimately on sleep and performance. We developed a subtractive technology using optical filters that block light wavelengths below 480 nm. In a controlled experimental setting, and in volunteer shiftworkers in field studies conducted in a hospital and nuclear power plant, we demonstrate that filtering out light wavelengths between 470 and 480 nm normalizes melatonin and cortisol secretion, prevents shifts in core clock gene expression, and improves sleep and performance compared to exposure to unfiltered nocturnal light. These findings may have important implications for the health and wellbeing of rotating shiftworkers.

Michael Mott
Assistant Professor, Department of Teacher Education
Univ. of Mississippi

Abstract
Light is universally understood as essential to the human condition. Yet light quality varies substantially in nature and in controlled environments, leading to questions of which artificial light characteristics facilitate maximum learning. Recent research has examined lighting variables of color temperature and illumination for affecting sleep, mood, focus, motivation, concentration, and work and school performance. This has resulted in artificial light systems intended to support human beings in their actualization through dynamic lighting technology, allowing for different lighting conditions per task. A total of 84 third graders were exposed to either focus (6000K-100fc average maintained) or normal lighting. Focus lighting led to a higher percentage increase in oral reading fluency performance (36%) than did control lighting (17%). No lighting effects were found for motivation or concentration, possibly attributable to the younger age level of respondents as compared with European studies. These findings illuminate the need for further research on artificial light and learning.

Eunice Noell-Waggoner
Founding Chair
Center of Design for an Aging Society

Abstract
LEDs will be the answer for the lighting needs of the growing 65+ age group, only if normal age-related vision changes are addressed. Although older people need higher levels of light to maximize aging vision, caution must be exercise to control glare. Glare is enemy #1 of older eyes and those with eye diseases. As mobility decreases, so does exposure to daylight.  Seniors need high levels of bluish light during the day (to mimic daylight) and lower levels of warm light at night. The color shifting of LEDs holds great promise to improve the circadian rhythm of seniors, especially those in care facilities.
