Hangzhou Bay Bridge Lighting across the board commissioning completed

The evening of March 20th, the Hangzhou bay bridge lighting project announced the end of the whole line debugging. Tiny spots light like a string of pearls, with the world's longest cross sea bridge, extending in the vast sea. According to the command of the bridge, the bridge bridge lighting project is dragon punchline, from May 21, 2007 start date, after more than and 300 days of hard work, today marks the end of debugging, bridge follow-up project has made significant progress, according to the predetermined target opening and a major step forward. It is understood that the bridge lighting project includes 1844 sets of street lamps, fog lamps, 1844 sets, all kinds of distribution box (socket box) more than 3600 units, more than 10000 sets of various types of lamps. The entire lighting engineering bridge lighting and landscape lighting two parts. Bridge headquarters, said the person concerned, the bridge lighting, that is, a total of 36 km of the main bridge (Road) and the south side of the road service area Ramp Bridge Road lighting. The main bridge is 250 watts high pressure sodium lamp, ramp bridge is a 150 Watt High Pressure Sodium lamp. Lamps are using the latest GOLF model, the service life of more than 20 years. Because of the large wind speed on the bridge and the salt fog weather, the corrosion is very strong. Now the design lamp life of more than 30 years, the wall thickness is larger than 6 mm, wind resistance at maximum wind speed 39 meters per second design. In view of the bridge street lamp vibration is larger, separately for each street lamp design damping system and dual anti dropping device, the maximum to avoid harm to the bridge falling head of vehicles, to ensure the firmness of the lighting uniformity and lighting installation. It is reported that landscape lighting, including North and South Channel Bridge, North and south approach and around the tower platform landscape lighting. Among them, the bridge landscape lighting includes tower lighting, stay cable lighting, beam bottom lighting. Tower lighting will be the three North and south of the outline of the tower lit, fully embodies the majesty of the bridge and tall and straight. 250 Watt light will come out with the outline of the north and South Bridge Approach Lighting north and south, reflects the "design effect on sea dragon". The entire lighting engineering application of the advanced control system, the intelligent monitoring system of bridge lighting Bridge Engineering in China, to achieve the single lamp control, fault detection and dimming function of geographic information system and realize the real-time detection of abnormal, and street lights and fog lamp control. In addition, the bridge due to special geographical location, frequent fog weather, in order to ensure traffic safety, in each light pole from the ground a LED fog lamp set 1.5 meters, this bridge was first used in domestic engineering. It is reported that, LED light source, energy saving and high efficiency, service life of 100 thousand hours, can meet the requirements of energy saving, and can ensure traffic safety in foggy weather.
