A forthcoming publication from the LRC will offer guidelines and best practices for daylighting schools. The “Guide for Daylighting Schools” was created for the Daylight Dividends program by Innovative Design of Raleigh, N.C., an architectural firm specializing in energy-efficient, sustainable building design. The guide is a “how to” for creating effective daylighting in schools without dramatically adding to the initial cost of the building.

Lighting scientists are continually looking for ways to help us to see better, perform visual tasks with more accuracy, and save energy at the same time. This quest for better quality lighting inevitably leads to studies to understand how light helps or hinders, and how our visual systems perform under various lighting conditions. LRC researchers recently were awarded an international prize for their published study evaluating whether light sources that produce smaller pupil sizes result in better visual task performance.

Even if light-emitting diodes can demonstrate long life, poor construction and misguided application of LED systems can lead to short operating life, consumer dissatisfaction and dismissal of the technology. That was the message presented by N. Narendran, Ph.D., director of research at the Lighting Research Center, and Jean Paul Freyssinier, LRC lighting design specialist, at LED Expo 2004, a four-day international conference dedicated to LEDs.

The Lighting Research Center announced in June that it will work with Evident Technologies of Troy, N.Y., to develop and demonstrate new, efficient white light-emitting diodes (LEDs) for use in general illumination.

Funding for the project comes from the New York State Energy Research and Development Authority (NYSERDA). LED technology will lead to significant energy cost savings and environmental benefits as solid-state lighting begins to replace incandescent and other low-efficiency lighting sources in residential and commercial buildings.

The LRC launched a new series of educational seminars presented via the Internet and designed to provide the latest information on lighting topics important to individuals and their businesses.

From March through June, LIVE! From the LRC brought lighting experts to participants’ offices via the Internet. The first four seminars focused on outdoor lighting, energy-efficient and load-responsive lighting, LEDs and how they are revolutionizing lighting, and light and human health. The series allows people to have their questions answered by the leading authorities in lighting today. More seminars are being planned for the fall.

Those interested in gaining more knowledge of solid-state lighting and light-emitting diodes should make plans to attend the LRC's LED Lighting Institute. This intensive three-day, hands-on workshop is scheduled for September 22-24, 2004. Seating is limited at this popular program, so make your reservation now.

LRC experts will help participants learn more about this rapidly evolving lighting technology through presentations about current research and applications, as well as hands-on design work. Other topics include incorporating LED technologies into architectural lighting fixtures, developing optical components that take advantage of LED characteristics, and designing applications using LEDs. Participants earn 20 continuing education units.

Lutron Electronics Scholarship in Lighting supports graduate education
Anjan Sarkar

Lutron Electronics Co., Inc. has again funded a scholarship for a graduate student at the Lighting Research Center. Each year since 1996, the Lutron Electronics Scholarship in Lighting has been awarded to a student in the Master of Science in Lighting program who has demonstrated outstanding academic performance and leadership, and who is planning to undertake research involving advanced lighting technologies or lighting controls.

"Through this scholarship, Lutron Electronics Co. has once again demonstrated its commitment to generous support and interest in helping to educate the future leaders in the field of lighting," says Dan Frering, LRC manager of education.

The most recent recipient of the Lutron Electronics Scholarship in Lighting is Anjan Sarkar, who is preparing to enter his second year in the MS in Lighting program. "I am truly honored to have been chosen to receive this scholarship," said Sarkar, who says he is particularly interested in how lighting and lighting controls affect people and the way they live and work.

Lutron Electronics Company, Inc., founded in 1961, is a leading manufacturer of lighting controls. Lutron offers more than 10,000 products for residential and commercial applications. Visit the Lutron web site at
