Osram Opto Semiconductors GmbH of Regensburg, Germany and China’s Tsinghua Tong Fang Co Ltd have teamed to illuminate the dragon-shaped water fountains in Beijing’s Olympic Park with Osram’s Golden Dragon LEDs.
In July, Tong Fang installed its dragon-shaped water fountains along the northeast side of the Bird’s Nest and the Water Cube in the Olympic Park. The fountains were outfitted with Osram Golden Dragon with lens and enhanced Thinfilm LED components, providing their golden glow.
Projects like the dragon-shaped fountains reflect the expanding opportunities that customers are finding to create original LED solid-state lighting applications, says Osram. More than 600m long, the ‘Dragon’ is formed by thousands of water jets arranged in a long curve cutting through the Olympic Park, comprising a river stretching 2km. The jets launch water columns as high as 6m, creating a kind of rolling wave (resembling the body of a dragon gliding through the air). At the base of each column, mounted 10cm underwater, a lamp containing 24 Osram Golden Dragon LEDs radiates yellow light upwards to a height of 15m, illuminating the ‘dragon’ for 4-5 hours every evening. Altogether, 1920 lamps containing 46,080 Golden Dragon LEDs help bring the dragon fountain to life.
Osram Opto says that partnering with Chinese companies such as Tong Fang (with which it has worked before) is key to developing China’s LED market. “This kind of innovative and creative thinking is precisely how we aim to revolutionize the lighting industry in China and the rest of the world,” says Osram Opto Semiconductors Asia’s CEO Dr Alfred Felder.
Osram Opto claims that its Golden Dragon with lens and enhanced Thinfilm LEDs come with one of the narrowest viewing angle integrated lenses in the industry (just 20°), taking up less space and reducing the need for secondary optics. Also, the high optical efficiency (61lm/W) of the yellow LEDs enhances energy efficiency, while the lifespan of more than 50,000 hours (under appropriate operating conditions) minimizes maintenance costs.
