In line with the Korean Government’s call to implement more energy-efficient solutions, Wonju City in Gwang Won province, South Korea, has installed Praus 150W streetlights with Osram Opto Semiconductors’ Golden Dragon Plus LEDs, which represent the longest LED street light installation to-date in Korea.
Around 520 LED-based streetlamps, with 37,440 Golden Dragon Plus LEDs, were installed along the road from Wonju interchange to South Wonju interchange, and replaced traditional MH 250W and 400W street lamps. Galed anticipates that the LED-based street lamps can save 48% power consumption, while the total cost of ownership can further reduce because of the exceptional 50,000 hour lifetime of Golden Dragon Plus LEDs, minimizing maintenance and replacement costs.
The Korean Government plans to replace all incandescent light bulbs at public facilities with more energy-efficient LED bulbs by 2012. Lee Myung-bak, the president of South Korea, has personally stressed the importance of energy conservation in today’s economic environment, instructing local chiefs to focus on ways to reduce energy consumption in their regions.
Golden Dragon Plus LEDs offer full-color spectrum brightness, consume 80% less electricity than incandescent lamps, and can last more than 50,000 hours. Furthermore, the availability of cool and warm white LEDs with excellent color rendering, offers the flexibility to adjust color temperatures to specific street lighting applications.
Osram is part of the industry sector of Siemens. Its subsidiary, Osram Opto Semiconductors GmbH in Regensburg (Germany), offers its customers solutions based on semiconductor technology for lighting, sensor and visualization applications.
GALED Co. Ltd. is a Korean company established in 2007 with expertise on designing LED applications for street lightings. Its products and service range from developing, manufacturing, to marketing eco-friendly LED lighting system.
