which is the best high lamp manufacturers? Small edit today want to introduce you to high lamp ( 。 jschindo。 com) Generally refers to a kind of new lighting, by a 15 meters of steel column of light pole and a high power combination lamp holder. Its height is 15 40 meters. It is mainly composed of lamp holder, internal light appliances, rod body and base parts. The shape of the lamp holder can according to user requirements, and lighting requirements specific to determine the surrounding environment. High lamp inside the lamp is mainly composed of omni and projection lamp. Light source for lighting radius is 60 meters NG400 high-pressure sodium lamp. Rod body is commonly cylindrical monomer structure, composed of steel rolling, height is 25 meters. 40 m is composed of more than 25 m steel cylindrical light pole and high-power lamp of new lighting device. According to the market demand, shandong light, high lamp manufacturers, most complete function, reasonable structure, stable performance, convenient operation and use. Widely used in square, Bridges, ports, docks, train marshalling station, the airport tarmac and broad road of large area lighting. Light, the light pole there are two main types: cone and polygon pyramid; ( 1) Conical light pole of roundness error must not exceed 5 meters; 。 ( 2) The side of the polygon sprayed light pole distance and diagonal distance deviation less than 1%. ( 3) Light pole on the surface of the single section rod distortion error shall not be greater than 7 degrees; 。 High lamp light pole in detail: shall have the light pole axis straightness error of less than 2 times of the light pole length; 。 Should conform to the design of the light pole GBJ17 steel structure design specification. Wind pressure for the design of the maximum stress should be less than material strength under the standard value. High light pole of the welding quality shall comply with the requirements of GB/T12469, can not have cracks, slag inclusion, flash, burn through, and impact strength of arc crater needle hole, can not have defects such as wrinkling, interrupt. Stainless steel composite steel welding shall comply with the relevant provisions of the GB/T13148. Lamp shall not be less than 8 m at a time. Light pole joining together, in joining together light pole and add a sleeve, sleeve length is not less than 300 mm, thickness is not less than 80% of the light pole wall thickness. Plug-in lamp post insertion length should be greater than the plug-in light pole big end diameter of 1. 5 times. Light pole plug in, fit clearance shall not be greater than 3 mm, light pole length should comply with the design requirements. Light pole welding inspection requirements shall be in line with the GB/T11345 evaluation criteria. Light pole door ( Or open) Should be strengthened. To ensure the mechanical properties of not less than the strength of the door is not open.
