Chongqing main city cross river bridge facelift 28 thousand and 500 sets of LED lights, power saving 2 million 380 thousand degrees

Chongqing daily news reporter, October 8th from the Chongqing municipal lighting Bureau, from mid July onwards, in Yangtze River bridge, Caiyuanba Yangtze River bridge Shibanpo (including railway bridge), the yellow garden bridge, river bridge, Yuao bridge (including light rail double line bridge), Jiahua bridge and Shimen bridge, Egongyan bridge 10 Bridge and etc. Yangtze River and Jialing River 15 barges were lighting upgrade project, is expected to be completed in the end of this month.

According to reports, the project design unit for Beijing Tsinghua Tongheng urban planning and Design Institute, the project overall follow the "elegant atmosphere and advanced science and technology" and the principle of "reduce, add, change, even" ideas, four big promotion and ultimately achieve overall effect, energy saving and environmental protection, linkage control, convenient maintenance "".

City Lighting Bureau official said, the project has three highlights. One is the "run out of the river". On the Yangtze River Bridge and pontoon with warm light, on the Jialing River Bridge and pontoon with cold light, through the contrast of changes in temperature way to create a more pleasing, the vitality of the city at night. Two is the daily and festival two kinds of lighting control mode. The daily pattern mainly presents the structural characteristics of the bridge to achieve the "quiet elegance" effect; the festival model mainly displays the color rhythm of the light, and reflects the effect of "vigor Jiangcheng". Three is energy-saving emission reduction. The project will eliminate 12 thousand and 600 sets of high energy consumption traditional light source, the new 28 thousand and 500 sets of LED energy-saving new light source, the total power down 1332 kilowatts, saving energy consumption of about 2 million 380 thousand degrees / year, equivalent to 1801 tons of carbon emission reduction.

Reporters from the city lighting Bureau learned that the current bridge yellow garden bridge, Shibanpo bridge, Jiahua bridge the old lamps have been removed, the rest of the bridge project progress more smoothly, such as continuous rain etc., several bridges will be held this month at the end of the new lighting light in succession.

Symbiosis between ancient and modern

The status quo: the bridge itself features are not clear, new and old bridge landscape adhesion effect, lack of overall aesthetic.

Metamorphosis: to warm color as the basic color, highlighting new and old "ancient symbiotic" landscape effect.

Design new LED lamps, 3060 sets, laying cables 26 thousand meters, changing distribution box 4. After upgrading the landscape, the total power is reduced by 246 kW, the annual electricity consumption is 400 thousand degrees, the power saving percentage is 47%, equivalent to reducing carbon emissions by 312 tons / year.

Yellow garden bridge

Then, sometime

Status: lighting, brightness decay serious secondary relation is not clear, and the surrounding environment lack of cohesion, lack of overall color clutter beauty, and landscape planning is not appropriate.

In light color turned as the basic color, showing a yellow flickering "dim shadows" landscape effect.

Design new LED lamps, 3235 sets, laying cables 44 thousand meters, changing distribution box 6. To improve the landscape, reduce the total power of 110 kilowatts, annual energy saving 190 thousand degrees, the percentage is 22%, equivalent to reducing carbon emissions of 148 tons / year.

Trans River Changhong

Status quo: the bridge features are not prominent enough to realize the dynamic effect and mode control, the distribution system is not reasonable and the maintenance is inconvenient.

Change: to warm color as the basic tone, focus on highlighting the theme of the bridge color, dynamic echoes train train, fully display the "cross river Changhong" landscape effects.

Design new LED energy-saving lamps 8924 sets, re release 30600 meters cable, replace the distribution box 6. After upgrading the landscape, the total power is reduced by 132 kW, the annual electricity consumption is 410 thousand degrees, the power saving percentage is 23%, equivalent to reducing carbon emissions by 320 tons / year.

Double door Zhenjiang

Status quo: the characteristics of the bridge itself is not clear, the effect of the adhesion of the landscape, the lack of overall aesthetic.

Change: to warm color as the basic tone, highlighting the "double door Zhenjiang" landscape effects.

Design new LED energy-saving lamps 4694 sets, 288 sets of metal halide lamp, re release 28200 meters cable, replacement, new distribution box total of 12 units. After upgrading the landscape, the total power is reduced by 429 kW, the annual electricity consumption is 590 thousand degrees, the power saving percentage is 60%, equivalent to reducing carbon emissions by 460 tons / year.

Ka Wah Bridge

- lumen of light and shade

The status quo: the spot is obvious, outdated facilities, light serious, unable to realize the mode control, the lack of overall aesthetic.

Change: with cold light color as basic tone, combine bridge body to show the beauty of bridge body and the intention of flower bloom, highlight the "luminous lumen" landscape effect.

Design new LED lamps, 1928 sets, laying cables 13 thousand and 500 meters, changing distribution box 4. After upgrading the landscape, the total power is reduced by 43 kW, the annual electricity consumption is 90 thousand degrees, the power saving percentage is 16%, equivalent to reducing carbon emissions by 70 tons / year.

Jialing River Bridge

Corresponding deficiency and excess

Status: lack of primary and secondary relations, lack of brightness level, dynamic control and mode control can not be achieved.

Transformation: through the actual situation, light and color means to open the relationship between the adjacent bridge and its own level, and show the "virtual and appropriate" landscape effect.

Design new LED energy-saving lamps 1999 sets, re release 8500 meters cable, replace the distribution box 5. After upgrading the landscape, the total power is reduced by 68 kW, the annual electricity consumption is 120 thousand degrees, the power saving percentage is 49%, equivalent to reducing carbon emissions by 93 tons / year.

Shimen Bridge

- the cable River

Status: lighting, brightness decay serious secondary relation is not clear, and the surrounding environment lack of cohesion, lack of overall color clutter beauty, and landscape planning is not appropriate.

Change: basic color with cold light
