Seoul Semiconductor’s LEDs used in ORNL’s ZEBRAlliance test house

South Korean LED maker Seoul Semiconductor says that its Acriche A3 AC LED is featured in solid-state lighting modules (designed by Lumenique and produced by Molex Inc) installed throughout an energy-saving home as part of the project ZEBRAlliance (the Zero Energy Building Research Alliance) at Oak Ridge National Laboratories (ORNL). Next Monday (20 September) a ribbon-cutting ceremony will mark completion of the project at its site in the Wolf Creek Subdivision, 102 Cross Pointe Lane, Oak Ridge, TN, USA.

ZEBRAlliance is a collaborative public–private effort between Schaad LLC, the Tennessee Valley Authority, the US Department of Energy and ORNL to field-test two pairs of energy-saving residences.

The alliance aims to spotlight energy conservation efforts that can reduce the load on the existing electrical grid and curb dependence on non-renewable energy sources. Energy use, lighting quality and maintenance requirements will be monitored for two years. Data from the house outfitted with Acriche LEDs will be compared against that of a house using compact fluorescent lights (CFLs). The results should help buildings, lighting designers and homeowners make energy-saving lighting decisions, says Seoul Semiconductor.

Because Acriche LEDs do not use electronics to convert AC line voltage into DC (as do most other solid-state lighting devices), they are more energy- and cost-efficient lighting products than other LED options, claims the firm.

"Seoul Semiconductor is proud to support ZEBRAlliance's effort to boost the energy efficiency of residential lighting through our working partner, Molex,” says Doug Hardman, Seoul Semiconductor’s North American strategic marketing director. “This project will help raise awareness about LEDs and their ability to provide energy-saving, cost-efficient, and longer-lasting lighting solutions than homeowners currently use.”
