The nearly mile-long white and colored
illumination spans bridges, climbs landmark skyscrapers, and marks
Signify’s largest-ever connected architectural lighting project.
Signify has switched on its largest-ever connected architectural lighting
project, stretching some 50,000 scene-changing LED luminaires nearly a
mile over 40 buildings and three bridges along financial and tourist
districts of Shanghai’s sprawling waterfront.
The
Shanghai Municipality and Signify switched on the LED lighting earlier
this month to signal the opening of the city’s week-long China
International Import Expo, in a ceremony witnessed by Chinese president
Xi Jinping. Shanghai is directly administered by the country’s central
government.
The LED lights span three
bridges — the Yangpu, Nanpu, and Xupu — which all cross the Huangpu
river. Landmark buildings lit by the luminaires include the Shangri-La
Hotel and the Shanghai Jinmao Tower in the Pudong district, and in all
about 27,000 white luminaires illuminate the red tops of Pudong’s
skyscrapers.
The 1.2-km-long (0.75-mile)
project includes a number of colored lights as well, including across
the three bridges. At one point on the riverfront, red LED lights create
a waterfall effect.
About
7800 of the 50,000 Signify LED luminaires run across the Yangpu (top),
Nanpu (middle), and Xupu bridges, including color models.
Using Signify’s Interact Landmark control system, Shanghai can alter individual and groups of lights to create different scenes.
The
Interact systems also serves to monitor the lights themselves, noting
usage and energy consumption and identifying maintenance issues.
“The
upgraded lighting system helps demonstrate Shanghai’s cultural heritage
in a more vivid way, creating impressive night scenes in an
energy-efficient way,” said John Wang, Signify’s president of greater
China and senior vice president.
Signify
said the LED lighting and controls will reduce energy consumption by
50–70% “when compared to previous areas lit by conventional lighting.”
An optional “late night” mode helps in the energy-saving effort.
