A slogan "Greetings Motherland" is displayed on a Sun Valley pillar at the Expo Boulevard .

The Expo Boulevard in the site of World Expo 2010 will present an LED lighting show every night during the National Day holiday from today to commemorate the 60th anniversary of the founding of the People's Republic of China.

LED, which means light-emitting diode, is known for its high luminosity, endurance, controllability and low energy consumption when used in lighting. Nearly 80,000 LED lights, all produced by Shanghai manufacturers, have been installed on the six Sun Valley pillars in the Expo Boulevard .

The National Day LED show will feature images like the fluttering national flags and the jaunty Haibao as well as slogans like "Greetings Motherland" through changes of colors and dynamics of visual elements.

Residents will be able to watch the LED show from the top of nearby buildings, advisably the Lupu Bridge.

The LED lighting will have more functions in next year's World Expo 2010, including interactive features through which spectators can change the visual elements on the LED lighting canvas by waving hands to certain video cameras.
