Lighting Research Center Innovation Featured in Scientific American

A U.S. patent issued to inventors from the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute was featured in last month’s issue of Scientific American. The April magazine’s Patent Watch column reviewed the “Solid state light source light bulb” invented by LRC professor and director of research Nadarajah Narendran and LRC co-inventors Jean Paul Freyssinier, senior research scientist, and Yiting Zhu, research scientist.

The patented light-emitting diode (LED) light bulb is designed to replace common incandescent and compact fluorescent lamps found in most homes, but addresses problems typically found in LED lamps currently available on the market. The unique design allows for better thermal management of the LEDs to significantly improve the reliability and the light output of the light bulb. The novel optical design, along with materials inside to refract and reflect light, allow the lamp’s light output distribution to match that of a traditional incandescent lamp. When used in a luminaire such as a table or floor lamp, it maintains a similar appearance and overall light distribution, eliminating the dark shadows and spotlight effect common with other LED replacement lamps.

About the Lighting Research Center
The Lighting Research Center (LRC) at Rensselaer Polytechnic Institute is the world's leading center for lighting research and education. Established in 1988 by the New York State Energy Research and Development Authority (NYSERDA), the LRC conducts research in solid-state lighting, light and health, transportation lighting and safety, energy efficiency, and plant pathology. LRC lighting scientists with multidisciplinary expertise in research, technology, design, and human factors, collaborate with a global network of leading manufacturers and government agencies, developing innovative lighting solutions for projects that range from the Boeing 787 Dreamliner to U.S. Navy submarines to hospital neonatal intensive-care units. In 1990, the LRC became the first university research center to offer graduate degrees in lighting and today, offers a M.S. in lighting and a Ph.D. to educate future leaders in lighting. With 35 full-time faculty and staff, 15 graduate students, and a 30,000 sq. ft. laboratory space, the LRC is the largest university-based lighting research and education organization in the world.

About Rensselaer Polytechnic Institute
Rensselaer Polytechnic Institute, founded in 1824, is America's first technological research university. The university offers bachelor's, master's, and doctoral degrees in engineering; the sciences; information technology and web sciences; architecture; management; and the arts, humanities, and social sciences. Rensselaer faculty advance research in a wide range of fields, with an emphasis on biotechnology, nanotechnology, computational science and engineering, data science, and the media arts and technology. The Institute has an established record of success in the transfer of technology from the laboratory to the marketplace, fulfilling its founding mission of applying science "to the common purposes of life."
