The Donghai Bridge project and the indispensable supporting project of Yangshan Port Area can meet the needs of the recent (2005), medium-term (2010) and long-term (2020) bulk container land collection and distribution of Yangshan Port Area, facilitating the settlement of the port. The district's water supply, power supply, communications and many other engineering needs are the country's key strategic projects.
The Donghai Bridge includes: the onshore section between the new and old levees of Luchao Port (that is, the section spanning the new flood control embankment to the end of the old dyke bridge after the landing of the bridge, with a total length of about 2.3km); the small tortoise from Luchaogang to Qixian Island About 25.3km of sea section between the islands (including a 5000t-class navigation hole, a 1000t-class navigation hole, two 300-500t-class navigation holes, and the rest are non-navigable holes in the sea area); and the small turtle island to Xiaoyang About 3.4km between the islands and the bridge section (mainly including the Kaishan section, the seawall section and the Zhuzhushan Bridge), the total length is about 32.5 km.
The main purpose of building the Donghai Bridge is to meet the requirements of traffic functions. Due to the special geographical location of the Donghai Bridge, the constraints of space and the influence of design concepts, it is impossible to leave too much room for lighting design. Therefore, our lighting design concept is to first use the unique rendering function of the lighting, using the unique rendering function of the lighting, using the color, brightness contrast and other methods to make it as bright and beautiful as possible.
The lighting project of the bridge is a whole, and it should have a unified style and coordinate with each other. Lighting design is to use the good combination of illumination, brightness and color. Through the contrast of light and dark, strength, weakness, size, height and density, the transition is smooth, the combination of points and faces forms the overall melody of the beat coordination, reflecting the modern atmosphere and showing the first in China. The style of the cross-sea bridge.
The lighting design of the Donghai Bridge itself includes both functional lighting and landscape lighting. Functional lighting is mainly to solve the night driving roads, bridge lighting, broaden the horizon, guide the driving direction, ensure traffic safety, smooth, and improve transportation efficiency. The purpose of landscape lighting is to reflect the three-dimensional sense of the Donghai Bridge through proper lighting techniques according to the characteristics of the bridge, and to express the beautiful appearance of the bridge from an aesthetic point of view. The Donghai Bridge that stretches the raft and the rough sea form a dynamic and integrated organic whole, which weakens the place that is not beautiful, and makes the beautiful place more beautiful. Use lighting art effects to create a comfortable, cozy, beautiful environment culture.

2. Design of functional lighting of Donghai Bridge
The functional lighting design of this project is mainly divided into three parts: the middle pole lighting of the Donghai Bridge, the road lighting of the Donghai Bridge outreach part, and the high pole lighting of the toll section. The functional lighting is mainly based on the GE brand SKY GEN. Light fixtures.
According to the characteristics of the on-site lighting method of the Donghai Bridge, the symmetrical lighting method is adopted to install the street lamp on the inner collision wall of the bridge. The height of the street lamp is 9.55 meters and 10 meters. The street lights are spaced 25 meters apart. Considering the characteristics of the Donghai Bridge during the actual operation, it is difficult to replace and maintain. Therefore, in the selection of the light source, we use GE's imported LU brand double-tube sodium lamp, which has high light efficiency, good fog permeability and long life. Up to 55,000 hours, further reducing the cost of replacement in the future. By calculating the average illuminance to be 37.68 LX, the illuminance uniformity is 0.5, and the glare index G is 7.28. Fully meet the needs of actual operating conditions.
In addition, due to the complex and harsh working conditions of the Donghai Bridge, there are high requirements for product safety, wind resistance, shock resistance and corrosion resistance. The quality and process of all lighting products provided by our company. A severe test was put forward. Under the cooperation and cooperation of our company with the owners and design institutes, we have specially customized all SKY GEN lamps and poles for the Donghai Bridge project:
