AGENDA:


Wednesday, Feb. 12
Hilton Garden Inn, Troy, NY

7:30 am - 8:50 am Registration, Continental Breakfast and Networking
8:50 am - 9:00 am Welcome Address
Joe Chow, Associate Dean, School of Engineering, RPI
9:00 am - 9:15 am Smart Lighting, Trends, Opportunities and Challenges
Robert Karlicek, ERC Director and Professor, Electrical, Computer & Systems Engineering Dept., RPI
The Smart Lighting Engineering Research Center is defining various evolutionary Smart Lighting paths by developing the transformative technologies and engineered systems more

required to simultaneously maximize human performance and minimize lighting energy consumption. This will be achieved with adaptive lighting systems that are smart enough to autonomously deliver illumination and new light-enabled services. This presentation will describe the technological frontiers of Smart Lighting and share how the Center, with the input and support of our global network of academic and industrial partners, is advancing new illumination-system concepts through advanced research and by training the next generation of scientists and engineers.

9:15 am - 9:30 am ERC Innovation and Industrial Collaboration Program
Silvia Mioc, ERC Director of Industrial Collaboration and Innovation, RPI
The presentation will give an overview of the various ways industry can interact with the ERC and the mechanisms in place to develop an entrepreneurial mindset in students.
9:30 am - 9:55 am Simulation and Control for Smart Spaces
Richard Radke, ERC Controls Thrust Leader and Professor, Electrical, Computer & Systems Engineering Dept., RPI
The presentation will give an overview of recent research in the Controls thrust. In particular, we will discuss progress in measuring, characterizing, optimizing, and controlling light more

distributions in real spaces, and the status of our new Smart Conference Room that will contain color-tunable lights, advanced control algorithms, and an array of time-of-flight sensors for occupancy tracking. We will also describe our continuing investigations into accurate lighting simulation for pre-visualizing and tuning lighting controller behavior.

9:55 am - 10:20 am Luminaire-Based Access Points as Small Cells in Converged Heterogeneous Networks
Tom Little, Associate ERC Director and Professor, Electrical & Computer Engineering Dept., BU
We are in the midst of a 'wireless data crunch' – the burgeoning mobile industry fueled by high performance smart phones and rich data consuming applications is driving enormous more

demand for wireless data access. The rise of Internet video is a contributing factor, but is one of many emerging data consumers including cloud-based applications such as file sharing under a ’continuously-connected’ paradigm. Fortunately, the consumption of data on mobile devices is predominantly in fixed locations – in the home or office, not while actively mobile. These fixed locations are amendable to techniques that offload data to alternative networks, or 'converged heterogeneous networks.'
In this presentation we consider Luminaires as a vehicle for hosting opportunistic wireless access in the form of small cells. As mobile devices gain proximity to these devices, we exploit the availability of localized, high-data rate asymmetric service to enhance the performance at these fixed positions. In the talk we describe the limits of this approach assuming optical communication in the visible spectrum, and the opportunities to augment existing radio frequency and mobile telephony technologies with an offloading technique.

10:20 am - 10:35 am Nanowall Light-Emitting Diodes to Address the Green Gap and Efficiency Droop
Daniel Feezell, Assistant Professor, Electrical & Computer Engineering Dept., UNM
Light-emitting diodes (LEDs) based on low-dimensional nanostructures may have the potential to address the green/yellow gap or improve efficiency droop. more

These non-planar structures can exhibit strain relaxation, very low dislocation densities, polarization-free heterointerfaces, and large effective active region areas. Their unique properties may be leveraged to increase LED efficiency or to enable new functionalities for smart-lighting applications. This talk will review our recent progress toward realizing electrically injected nanowall LEDs and highlight achievements and challenges in crystal growth, device fabrication, and characterization.

10:35 am - 11:05 am Break
11:05 am - 11:25 am Dynamic Optical Beam Control
Chaitanya Ullal, Assistant Professor, Materials Science & Engineering Dept., RPI
This talk will discuss the ERC’s latest plans for dynamic optical control, including scalable photonic crystal processing, flexible materials that provide a means for beam steering, more

and materials for dynamic refractive index control. The development of these new materials will allow rethinking the systems-level design, for example, creating 6" X 6" panels of light with LEDs on the edges and the ability to mix and shape the light output through both intrinsic and extrinsic controls. An update on the projects that have lead the center to address these problems, including electrowetting experiments and index of refraction / color converting encapsulants, will also be provided.

11:25 am – 11:40 am Phosphor Crystals for LEDs
Partha Dutta, ERC Deputy Director and Professor, Electrical, Computer & Systems Engineering Dept., RPI
The fundamental theoretical limits for efficacy and wall plug efficiency of phosphor converted white LEDs (pc-WLEDs) could be achieved only by eliminating the optical scattering more

losses in existing LED packages. One of the approaches for solving this shortcoming is by using optically transparent phosphor substrates. This also enables the usage of ultra-low activator doping concentration, thus, enhancing the luminous efficacy and the thermal quenching temperature of the phosphors. This talk will focus on the crystal growth processes developed at the Smart Lighting ERC to grow phosphor crystals of various compounds. The development of full spectrum phosphors and their impact on the economically viable Smart Lighting system design (with simpler control algorithms) will be presented.

11:40 am - 12:10 pm Student Perfect Pitch Competition: Finalists to present their research in 90 seconds. All industry representatives present are invited to judge the presentations – ballots will be provided
12:10 pm - 1:30 pm Lunch
1:30 pm - 1:40 pm Illumineering Curriculum: Smart Lighting Educational Modules
Ken Connor, Director of Education and Professor, Electrical, Computer & Systems Engineering Dept., RPI
The Illumineering Curriculum, developed to prepare our students for careers in Smart Lighting, promotes a multi-disciplinary educational experience more

including content from engineering (electrical, mechanical, optical, chemical, materials …), science (physics, chemistry …) , architecture (lighting design …), health, business and social sciences. Organized around a matrix of subtopics (e.g. Luminaire Design Optics, Health, Intellectual Property, LED Basics …), the curriculum is used to guide the development of content modules for both ERC education and outreach activities. The modular approach also allows for easy content contributions from any interested party including industry partners, providing an opportunity to both help strengthen the ERC education and outreach programs and introduce students and other program participants to the organization providing the educational materials.

1:40 pm - 1:50 pm Development of a VLC Sequential Relay Messaging Module for Intelligent Building Operations and Indoor Tracking
Kofi Nyarko, Associate Professor, Electrical & Computer Engineering Dept., Morgan State University
The goal of this project is to demonstrate how visible light communication (VLC) can play a pivotal role in making a vast number of the existing and new commercial buildings more

more energy efficient through intelligent building operations. In support of this goal, the objective of this research is to develop inexpensive LED luminaire modules capable of sequential broadcast communication through VLC. When combined with compatible VLC receivers, these modules enable intelligent control of building resources in addition to indoor occupant localization. One type of VLC receiver is a low cost system that interfaces with control modules, such as blind motors, plug-in controls, lighting, and thermostats, by receiving broadcasted signals over VLC where each control instruction is tagged with a unique ID. When a broadcast signal containing a matching ID is received, the receiver performs the desired action without requiring backchannel communication because the central system maintains state information. The central system also maintains indoor occupant position information through the use of another receiver that is designed to be carried by each occupant (i.e. smart ID tag). This position information is further utilized by the central system to direct intelligent building operations.

1:50 pm - 2:20 pm Keynote: The future of electronic illumination
Steven Paolini, President, Telelumen
Visible light is a uniquely valuable portion of the electromagnetic spectrum. In addition to enabling sight it can be used to transmit information. more

Specialized eye receptors allow us to see in color, see in low light, and synchronize our bodies to the sun’s daily rhythm. With proper attention to modulation, both data transmission and illumination can even be done at the same time. Daylight provides a great model and roadmap for solid state illumination. Beyond basic visual stimulation, illumination may have changes in spectral, temporal, spatial, and angular distribution that have been under presented in conventional electrical lighting. This talk will explore these aspects of visible light with a survey of where we came from, where we are, and where we may go in the future.
