Making Landings Safer at Remote Airfields and Airports

Airport runway with lights

Many remote communities, such as those in Alaska, depend on air transport for business, supplies, and emergency aid. However, night landings at remote airfields are often dangerous or impossible. Without adequate lighting systems for runways, it is difficult for pilots to locate an airfield and position their aircrafts for safe landings, especially in times of crisis.

Working with the Federal Aviation Administration (FAA), the Lighting Research Center is helping to make night landings at remote airfields safer and communities more accessible. Researchers are developing a handbook for remote airfield lighting systems that optimize performance while minimizing cost. The systems will be designed to be visually effective and reliable, use minimal energy, require low maintenance, and be easy to implement.  Full story. . .

Gathering and Sharing Data for Circadian Research


The Lighting Research Center is forming a collaborative group of researchers from around the world to collect data in different lighting applications using a special light measuring device known as the Daysimeter.

“The group’s goal is to create a cooperative forum of manufacturers, scholars, scientists, and physicians who are already working in clinical applications and work environments where photobiology and circadian light exposure could be important for health and productivity,” said Mark Rea, PhD, the director of the LRC.  Full story. . .

Delving Deep into Solid-State Lighting

LED MR16 Lamps

In addition to its application studies and field evaluations of solid-state lighting, the Lighting Research Center has been delving into the basics of LED performance at the package and system levels. Two studies were published this fall by the International Society for Optical Engineering (SPIE) as part of its proceedings for the Sixth International Conference on Solid State Lighting, held August 14-17 in San Diego.  Full story. . .

LRC Investigates Luminance Requirements for Signage

Lighted signage has become a mainstay for most retailers, restaurants, and other businesses. However, no luminance standards exist in North America for signs based on visibility. Instead, businesses often install brighter signs to compete with those of adjacent stores. With LEDs growing as a popular replacement for neon and fluorescent lamps in signage, the Lighting Research Center investigated the luminance requirements for backlighted, channel-letter signs.  Full story. . .

LRC Partners: It's the Collaboration

Part of the Lighting Research Center’s continued success in accomplishing its mission to advance the effective use of light is its ability to work collaboratively with other universities, government agencies, and industry.
LRC Partner organizations gathered recently at the LRC to review the latest research results and discuss lighting trends, needs, and ideas for the future. This collaboration ensures that many voices are heard as the LRC plans future research activities. Partners include Boeing, the California Energy Commission, GE Lighting, Genlyte Group, Hunter Fan Company, the New York State Energy Research and Development Authority, the Northwest Energy Efficiency Alliance, OSRAM SYLVANIA, Philips Lighting, the U.S. Environmental Protection Agency, the U.S. Department of Energy, and Xcel Energy. 

The LRC is currently accepting new Partners. Forward-looking companies and organizations consider their support of the LRC an investment in their future. Visit the LRC Partners Program Web site for more information.  Full story. . .

LRC Student Wins Design Award

Fei Hu

Second-year Master's of Lighting student Fei Hu has won a top award in the 2006 Optical Design Competition, sponsored by Optical Research Associates (ORA). 

Hu's entry in the competition, "An LED Light Fixture Design for Pathway Marking in a Park," demonstrated knowledge of optics, optical engineering, and optical design software. The LED pathway marking fixture was designed as a final project for the Lighting Technology and Applications course at the Lighting Research Center.

The award was announced at the SPIE Annual Meeting in August.  Full story. . .


ANNOUNCEMENT: A demonstration of the new Load Shedding Ballast system developed by the Lighting Research Center, OSRAM SYLVANIA, and Intech 21 is set for November 9, 2006. The system provides a cost-effective means of reducing building and utility system peak electric loads without sacrificing occupant productivity.
Developed through a contract with the New York State Energy Research and Development Authority (NYSERDA), the system consists of a high-efficiency, instant-start electronic fluorescent ballast that has been modified to reduce power and light output by 33% when a signal is received via a power line carrier (no extra control wires).
                  LOCATION: Consolidated Edison
