A 20 meters high traffic lights on the little lamp technology

Due to the high lamp irradiation range, so are suitable for large area lighting, such as airport, parking lot, park plaza, city square, station, wharf, yard, highways, stadium, overpasses, etc. Currently use different occasions of light,

due to the high lamp irradiation range, applicable to the airport, parking lot, park plaza, city square, station, wharf, yard, road, stadium, overpasses and places of large area lighting. At present, for different occasions, the classification of the light, and naming is different. Port is called, for example, high lamp, square is called high lamp, port high lamp, airport high lamp, explosion-proof high lamp, stainless steel high lamp and so on are named after them. At present, the market of the 400 watts - widely used high beam 1000 watts projection lamp, no dead Angle of 360 degrees lighting range. If the application of high lamp height between 20 to 45 metres, usually use lift high lamp. This effectively reduces the difficulty of the workers to install. Still have a kind of ordinary light, do not need to lift system, the cost is relatively low. Basic is divided into light, the light pole octagon, dodecagon, and 18 sprayed light pole body, by the high strength and high quality of steel plate shear, bending, and automatic welding. The surface of the zinc thermal erosion resistance, corrosion resistance, oxidation resistance. For 20 - service life For 30 years. Lightning protection system: lamp installation 1. 5 m long lightning rod, underground base installation 1 1 m long ground wire, with underground bolt welded. 20 m, 25 m and 30 m lifting lever lamp technology parameters: 20 m: light on a diameter of 260 mm, 460 mm diameter; Light pole is divided into two groups, the wall thickness of 6 mm / 8 mm25m respectively: the lamp on a diameter of 280 mm, the diameter of 540 mm light pole is divided into three groups, wall thickness of 6 mm / 8 mm respectively / 8 mm made of traffic lights
