Hangzhou Bay Bridge for the first large-scale light

Hangzhou Bay Bridge for the first large-scale lighting debugging

Yesterday, the first large-scale lighting debugging of Hangzhou Bay Bridge, "if it is at night, landscape lights, contour lights, lights are lit, the bridge will be more beautiful!"

Responsible for bridge lighting project engineer Zhao Renyi told reporters, according to the plan, by March 13th all lighting debugging completed, after March 15th, the north and south sides of the people will be able to see the spectacular night brilliantly illuminated the bridge.

There are 1844 lights

The lighting system of the bridge is divided into two parts: lighting and landscape, "the lighting system mainly refers to the street lamp, there are 1844 lamps, each lamp power of 250 watts, an average of every 42 meters." Zhao Renyi introduced the street all by Zhejiang Zhongqi Industrial Co Ltd production installation, through intelligent control system, which is a unique technology in the world, each lamp equipped with intelligent control module to control independently, so that managers can through the terminal system according to the actual traffic flow to adjust the brightness of street lamps and lamp open density, to achieve energy saving objective." Reporter observed, all the lights on the bridge are the same height, 12 meters away from the bridge street, the height of precision design, to ensure the effective width of street lamp can shine on the bridge, and spacing settings can also give full consideration to the effect of glare on the road, 42 meters distance can be reduced this effect to the lowest."

In addition, the lighting system also includes fog lights, fog lights with the number of lights, installed in the lamp post about 1.6 meters high, only in fog.

Landscape lights are divided into four kinds

To reflect the bridge majestic, than the lights. Bridge landscape lighting design is a very complex system, not only to consider the beautiful bridge, but also to consider the safety of vehicles and navigation vessels, therefore, the different sections of the bridge has a different landscape lighting arrangements. Zhao Renyi, the landscape is divided into 4 types, the first is the landscape lights, mainly in the north and South Bridge, there were 500 sets installed in the bridge on both sides of each lamp, a distance of 8 meters, is the north south approach lights respectively stretches 2 kilometers. The second is the cable lamp, mainly in the north and South Channel Bridge, the Southern Bridge 80 sets, 112 sets of the north channel bridge, taking into account the impact on traffic, light does not produce glare color change, to prevent, unity is a single white light." The third is the tower lighting, there is no actual lighting effects, mainly in order to display the bridge tower at night, three sets of cable tower set up a total of 130 sets of light. The fourth is the channel bridge night lights, respectively, mounted on both sides of the bridge, are 150 watts of power for the white floodlight, there are 574 sets.

Bright lights less chance

"Although all light sources are energy-efficient and after a rigorous bidding, but because of the number of its power consumption is still relatively large." Zhao Renyi, light is a landscape lamp is more than and 670 kW, an hour will consume more than and 670 degrees (KWH) of electricity, according to the daily lights 8 hour is more than 5 thousand and 300 degrees (KWH), if coupled with the lights, will cost more. Therefore, in general, only the lights are switched on, unless all the special commemorative events will turn on all the lights.

Fence every 5 km of a color

In addition to lighting, the design of the bridge guardrail color also fully take into account the impact on the driver's vision. If it is not under the bridge of the sea, people can not feel the car is in the "bridge", more like an ordinary highway. From the south to the north, a road in the past, the bridge guardrail color changes in the color, but also by the "warm" and "cold", 36 kilometers of the bridge was painted in 7 colors, almost every 5 kilometers a color, from the south to the north are red, orange, yellow, green, green, blue and purple, if you come from far away on the surface of the whole bridge, like a lie in the sea of colorful Changhong". The reason why the bridge guardrail color change, mainly in order to prevent the driver in the process of visual fatigue, increase the safety factor. Reporters noted that the bridge in the middle of the belt is not an ordinary green belt on the highway, but a block of color changes along with the anti glare panels, the bridge has a total of more than 7.2 pieces.
