Cooper lighting lights the world's first sea-crossing bridge

The rainbow flies for the overpass, and the dragon is lying on the sea. At 3:40 pm on May 1, 2008, the world's longest cross-sea bridge, Hangzhou Bay Bridge, was commissioned and opened to traffic. The Hangzhou Bay Bridge is 36 kilometers long. The bridge is designed according to the two-way six-lane expressway. The design speed is 100 km/h. The designed service life is 100 years. The estimated total investment is about 11.8 billion yuan. In the construction of the bridge, more than 250 technological innovations were obtained, and 9 series of independent core technologies were formed, creating a number of world firsts. The opening of the bridge shortened the land distance between Shanghai and Ningbo by 120 kilometers, forming a two-hour golden triangle traffic circle between Shanghai and Hangzhou, further enhancing the integration of the Yangtze River Delta urban agglomeration.

It is understood that the Hangzhou Bay Cross-sea Bridge lighting project has created a number of firsts in the same way as the main project of the bridge: the bridge deck lighting intelligent monitoring system is used for the first time in the domestic bridge project, with single lamp control, fault detection and dimming function. Real-time detection of geographic information and system anomalies, and simultaneous control of street lights and fog lights; to ensure driving safety, set a set of LED fog lights at 1.5 meters per light pole, which can meet the requirements of energy saving and environmental protection, and fully guarantee The driving safety in foggy days was adopted for the first time in the domestic cross-sea bridge project. The lighting division of the US Fortune 500 Cooper Company successfully signed the lighting contract for the project, responsible for all road lighting and flood lighting business of the entire bridge, and became the main provider of lighting for the Hangzhou Bay Bridge.

On April 30, 2008, Kim Lee Law, President of Cooper (China) Investment Co., Ltd. China, accepted an exclusive interview with Cooper's overseas language channel on Cooper's successful lighting of the Hangzhou Bay Bridge. In an interview, Kim Lee told reporters that Cooper is a Fortune 500 company with a long history of 175 years. Its Cooper Lighting Division originated from Thomas Edison and successfully lit up the Statue of Liberty and NASA Space Center. Leading the global lighting market. For more than 100 years, Cooper Lighting has been committed to the development of the lighting industry, and has attached great importance to and strict control over product quality, technical performance and production processes. Adhering to the innovative spirit and business intelligence of the inventor Edison, Cooper Lighting continues to focus on product innovation. The bridge lighting fixture GULF of the Hangzhou Bay Bridge is the Edison R&D Center of Cooper Lighting. Based on its in-depth market research and leading technical advantages, it is tailored to the application characteristics of the cross-sea bridge. According to Kim Lee, due to the high wind speed at sea and the salt spray weather, the corrosion is strong, which puts special requirements on the waterproof and dustproof performance of the lamps. GULF's whole lamp protection grade is IP66, which is the highest among domestic street lamp products. It is extremely rare in similar products. It can effectively prevent dust, water vapor, etc. from entering the light source cavity and electrical cavity, improving corrosion resistance, thus extending lamps and electrical appliances. The service life. The bridge pole is also specially designed with a wall thickness of 6 mm and the typhoon resistance is designed according to the maximum wind speed of 39 meters per second at a height of 10 meters. In view of the characteristics of the vehicle driving on the bridge and the impact of the bridge wave, the vibration of the street lamp is large. The design is equipped with a damping system and a double fall arrest device for each lamp, which effectively improves the seismic resistance of the whole lamp and minimizes the maximum The danger of the lamp head falling on the passing vehicles on the bridge. Due to Cooper's consistent attention to product quality in 175 years, the entire lighting system design of the cross-sea bridge can last for more than 30 years under the harsh coastal environment. In terms of technological innovation, Cooper's GULF luminaire adopts the black sky green lighting design concept, which can effectively prevent glare and strictly control the light pollution, thus providing drivers with a comfortable visual experience and reducing the accident rate. In addition, this luminaire uses a high-purity aluminum reflector with high reflectivity and excellent optical performance. Uniform, good light distribution increases the effective width of the street light to the bridge, reducing the number of street lamps required. In order to achieve the effect of reducing costs and environmental protection and energy saving.

Through ICS's interview with Kim Lee, we saw that Cooper's long history, strong technical strength, excellent brand image, superior product quality and persistent innovation ensure that it can be among many competitors. To stand out and win the world's first sea-crossing bridge, this is a remarkable project. This will lay a solid foundation for Cooper's future brilliant achievements in the domestic lighting industry.
