Qidu North Bridge, hailed as “ the most beautiful single-pillar cable-stayed bridge” in Wenzhou City. It is 4.7 kilometers long in total and 2.3 kilometers long over the river.
Focusing on the positioning and theme of the whole design, combined with environment-protection(avoid light pollution), safety(value traffic safety), innovation(avoid thoughtless cluttering), local culture(reflect Oujiang river’s landscape)， artistic quality(harmoniously blend into surroundings on color) into the designing solution, concluded with an designing concept of “inheritage, esthetics, spectacularity, harmony”. Through light it reflects the continuity of cross-river development, the beauty created by mixing colors of the lights, the splendor on overall design, the unity of the whole night scene.
It upholds the tenet that illumination is an art of refining, organizing designers from different professions to survey on site since designing phase, simulating the structure and colors of different parts of the bridge, takes into account site environment, weather environment, hydrological environment, light fixtures, vessels’ sailing in the river, doing light simulation from perspectives of on the bridge, on the banks, on the river, cross the bridge to learn and finalize the bridge’s capability on expressing and integrated illumination effects, creates an spectacular sight of the bridge that people will look at it in awe of its loftiness and artistic power.
The bridge uses only 12 pcs 500W narrow-beam city color lights, or RGBW projector lights, but illuminates 2 main towers perfectly, highlighting bridge pillars and columns, and more than 3000 medium-beam linear wallwasher light to illuminate the box girder, making the streamline of the principal part stand out in the evening, meanwhile dyeing the waters under the bridge, thus make Qidu North Bridge and the surrounding nightscape enhance each other’s beauty.
The city color light’s beam spread, narrow as 4degree, illuminates the pillars and columns precisely and cut down light spill to a minimum, avoiding light glare and sight-interference to drivers and pedestrians on the bridge, also maximizing the light utility. All the city color light and wallwasher lights use intelligent logarithmic controlling technology, which ensures high color saturation and makes the bridge vividly decorated.
