A light 3. How much money 5 metres of solar street light

Light, usually under 15 meters above 35 meters of steel conical light pole and high-power modular fixtures are composed of new type of lighting. It is made up of lamp holder, light, electric lamps and lanterns, rod body and basic parts. Light, scope of application is very wide, such as city square

high lamp is usually referred to by more than 15 meters, 35 meters below the steel conical light pole and high-power lamp holder of new type of lighting. It is made up of lamp holder, internal high lamp, rod body and base parts. High lamp is widely used in city square, station, wharf, yard, highways, stadium and overpasses. High lamp lighting range, high brightness, has become an indispensable part of urban outdoor lighting, get the favour of people. However, when high lamp manufacturer production, must meet the following production standards. A, material standard, in the light of the light, open working environment, all the steel components, such as light pole, immersed in zinc, to ensure that the corrosion resistance of 30 years. The steel for plug-in or flange, installation spot welding step by step, eliminate hidden dangers. Aluminum oxide. Stainless steel and aluminum parts and standard parts made from stainless steel exposed to outdoor. Electric contact parts for brass or silver electrolytic copper, and stainless steel suspension cable, install with the current national standards. At least 80 microns and passivating galvanized. Second, high lamp standard die casting aluminum housing is easy to heat dissipation, can effectively control the temperature, prolong service life. Prone to mutation, toughened glass has a thermal stability, internal flame resistant and high temperature resistant wire, service entrance has a sealing device, effectively prevent moisture from entering. More than in IP65 protection class of lamps and lanterns, lamp holder can withstand the 30 m/s wind speed. 。 Third, the service life of the light source standard for 50000 hours, high efficiency of high pressure sodium lamp, or specular light emitting diode light source should be instantaneous trigger function again, is usually 200 watts - 1000 watts, etc. The power supply voltage is 220 v. Fourth, power factor standard shall be provided with sufficient capacity of the power factor of adjusting capacitor, so that the circuit power factor is less than 0. 85 - 0. 95 ( Need special order) 。 The above four standards, high lamp manufacturers must pay special attention to in production. Light is a large lighting appliances. If do not accord with standard of produce, install after may affect personal safety. Finally, if the light does not conform to the standard, light will be easy to damage and not bright, so the maintenance in the future will be very troublesome.
