Chongqing main bridge across the river to replace 28 thousand and 500 sets of LED light year electricity saving of 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, this 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 use of daily and holiday lighting control mode two. The main features of the daily pattern of the bridge structure, in order to achieve the "quiet and elegant" effect; holiday mode mainly shows the color rhythm of light, reflecting the "dynamic Jiangcheng" effect. Three energy-saving emission reduction. The project will eliminate 12 thousand and 600 sets of high energy consumption of traditional light sources, new sets of new energy saving LED light source, the total power of 1332 kilowatts, can save energy consumption of about 2 million 380 thousand degrees / year, equivalent to carbon emission reduction of 1801 tons.

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.

Yangtze River bridge (including double track bridge)

Ancient and modern symbiosis

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.

The design of new LED lamps 3060 sets, laying cable 26 thousand meters, replace the distribution box of 4. After the upgrade, the total power of 246 kilowatts, the annual savings of electricity consumption of 400 thousand degrees, saving percentage of 47%, equivalent to reducing carbon emissions of 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.

The design of new LED lamps 3235 sets, laying cable 44 thousand meters, replace the distribution box of 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

Current situation: the bridge features are not prominent enough to achieve dynamic effects and mode control, power distribution system is not reasonable, maintenance inconvenience.

To warm light color as the basic tone, focus on highlighting the theme of the color of the bridge, the dynamic response of the train, fully demonstrated the cross river Changhong landscape effect.

Design new LED energy saving lamps 8924 sets, re cast cable 30600 meters, replace the distribution box of 6. After the upgrade, the total power of 132 kilowatts, the annual savings of electricity consumption of 410 thousand degrees, saving percentage of 23%, equivalent to reducing carbon emissions of 320 tons / year.

Zhenjiang

Status: the bridge's own characteristics are not clear, the effect of adhesion, lack of overall aesthetic.

To warm light color as the basic tone, highlighting the double door Zhenjiang landscape effect.

The design of new LED 4694 sets of energy-saving lamps, metal halide lamp 288 sets, re cast cable of 28200 meters, replacement, new distribution box of a total of 12 units. After the upgrade, the total power of 429 kilowatts, the annual savings of electricity consumption of 590 thousand degrees, saving percentage of 60%, equivalent to reducing carbon emissions of 460 tons / year.

Jiahua Bridge

Light lumen

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

Transformation: the cold light color as the basic color, combined with the bridge body to show the aesthetic sense of the bridge and the intention of the flowers bloom, highlighting the light and shade, the landscape effect.

The design of new LED lamps 1928 sets, laying cable 13 thousand and 500 meters, replace the distribution box of 4. After the upgrade, the total power of 43 kilowatts, the annual savings of electricity consumption of 90 thousand degrees, saving percentage of 16%, equivalent to reducing carbon emissions of 70 tons / year.

Jialing River Bridge

Virtual reality

Status: primary and secondary relationship is unknown, lack of brightness level, can not achieve dynamic control and mode control.

Through the actual situation, light color means to open the relationship between the adjacent bridge body and its own level, showing the actual situation of the landscape effect.

Design new LED energy saving lamps 1999 sets, re cast cable 8500 meters, replace the distribution box of 5. After the upgrade, the total power of 68 kilowatts, the annual savings of electricity consumption of 120 thousand degrees, saving percentage of 49%, equivalent to reducing carbon emissions of 93 tons / year.

Shimen Bridge

-- the great river

Status: lighting, brightness decay serious secondary relation is not clear, and the surrounding environment lack of cohesion, messy color
