USA - Cities and towns across the United States are considering ways to reduce outdoor lighting energy consumption, and much attention is being paid to the use of light-emitting diodes (LEDs). The LRC at Rensselaer Polytechnic Institute has released a new publication detailing field Test results for photovoltaic-powered LED luminaires installed at three public, outdoor sites in the Catskill Mountains region of upstate New York.
The project was initiated and co-funded by the New York State Energy Research and Development Authority (NYSERDA; http:// ) and Sullivan Renaissance ( http:// ), a beautification and community Improvement program principally funded by the Gerry Foundation.
The mission was to examine system performance, photometric performance, energy savings, and whether people accepted the photovoltaic (PV) LED outdoor lighting system. The publication, Field Test DELTA: Post-Top Photovoltaic Pathway Luminaire, evaluated twenty-four prototype Renaissance luminaires designed By Sullivan Renaissance, Philips Hadco and SolarOne (3) Solutions. The Renaissance is a post-top luminaire with a decorative, Victorian-style appearance that operates LED modules powered by PV panels. The luminaires were installed at three sites in New York's Sullivan County including Bethel, NY, site of the 1969 Woodstock concert festival.
" NYSERDA funded the independent evaluation of the Renaissance luminaire installations in Sullivan County on the hope that it would spur more of the adoption of PV-powered LED outdoor lighting. The study's findings are impressive and should help advance the use of this innovative type of lighting, Said NYSERDA President and CEO Francis J. Murray, Jr. “The three installations combined are expected to save 2700 kWhs per year compared to conventional outdoor lighting systems.â€
"By successfully combining traditional style with contemporary technology, the result was an off-grid luminaire that blended well with the rural surroundings, was well-received by the public, and required no utility power," said Jennifer Brons, LRC research scientist and DELTA Program manager. “Residents and visitors at all three sites were impressed with the PV LED system.â€
"The result of these field tests highlight that Philips' outdoor LED solutions can deliver multiple benefits to a community, in this case significant energy savings and an outdoor lighting experience that enhances the surroundings and secondary makes a community feel safer. This is a significant finding Which we believe can be replicated in communities around the world, and highlights what is possible when partners with world-leading competencies in lighting and solar join forces with forward-thinking end users,†said Eric Anderson, senior marketing manager, Philips Hadco.
" "The project and its findings open the door wider for an array of carbon-reducing technologies and techniques that are evolving at light speed. Accepted as state-of-the-art less than two years ago, the solar lighting system evaluated in this demonstration Is today almost 40 percent more efficient. SolarOne is pleased to be part of the visionary team that is leading these developments and putting them into practice," said Moneer H. Azzam, president and CEO, SolarOne Solutions.
