 general can be divided into the lift and the lift. Elevating the main stem height is generally more than 18 m, electric lift is easy to operate, lamp plate to work place, can automatically set off automatically, hanging ditch, unloading and wire rope. Lift 20 meters high lamp' Light, generally refers to more than 15 meters steel conical light pole and high-power modular fixtures are composed of new type of lighting. 】 Manual and electric hoist control mode, make the lamp panel can be safe and reliable led lights' LED street lamp is made of street lamp, LED lamps and lanterns with high efficiency, safety, energy saving, environmental protection, long service life, fast response speed, high color rendering index of unique advantages, the city lighting energy saving is of great significance. 】 From the ground to 2 factories. 5 meters, convenient maintenance. Manual remote control the length of the outlet line for 10 metres, operators in the rise and fall of 5 meters remote control lamp panel, this ensures that the operating personnel's personal security. Lift high lamp is equipped with a spare cable, when light plate fell to the lowest position, the cable end in electric control system' Electrical control system generally referred to as the secondary control circuit electric equipment, different devices have different control loops, and high voltage electrical equipment and control way of the low voltage electrical equipment is not the same. 】 Inserted into the lamp socket and the other end plate of the terminal box, so can the lamp panel for electricity directly, lamps and lanterns. Lift light, all the protection class reaches IP65 【 of lamps and lanterns IP65 IP is Ingress Protection, IP rating for electrical equipment enclosure Protection grade of foreign invasion, such as explosion-proof electric appliance, waterproof and dustproof appliances, sources are the standard of the international electrotechnical commission IEC 60529, this standard has been adopted in 2004 to the national standard. 】 International standards, in order to prevent the dust, rain water immersion, ensure the service life of the bulb. The material of lamps and lanterns generally USES the aluminum alloy plate with good corrosion resistance' Aluminum alloy is a kind of industrial building materials, depending on the materials used in various industries, according to surface treatment methods can be divided into the paint and paint products two kinds big. 】 And stainless steel. Of light, we say at ordinary times, in fact according to utility is differ in thousands ways, according to the classification of different using occasions of light, and the term of each different. Such as dock, called terminal high lamp, square, light, called square, name of the port high lamp, airport high lamp, explosion-proof high lamp, stainless steel high lamp and so on. Usually think that more than 15 m light pole, light, and 15 40 m, commonly used is 15 meters, 18 m, 20 m, 25 m, 30 m this 5 kinds of specifications of the most common. Other are usually the height of the specific customer request design, this also is we often say according to height of light.
