What is the principle of lifting rod lamp?

Lifting pole lights are widely used for large-area lighting in squares, overpasses, ports, docks, train yards, airport aprons and wide roads. The whole lighting facility is composed of light pole, light panel, lifting system, power distribution system, foundation and lightning protection device. Reasonable structure, stable performance and convenient operation and use. The design and adoption of its appearance conforms to the principle of giving priority to functions, coordinating with the environment and being beautiful and generous, which is consistent with the opinions of users.

High-pole lamp generally refers to a new type of lighting device consisting of steel cone-shaped lamp poles and high-power combined lamp holders over 15 meters. It consists of a lamp holder, a built-in lamp, a rod body and a basic part. The shape of the lamp holder can be determined according to the user's requirements, surrounding environment and lighting needs. Interior lights are mostly composed of floodlights and floodlights. The light source is NG400 high-pressure sodium lamp with a lighting radius of 60 meters. The rod body is generally a pyramid-shaped whole structure, which is made of rolled steel plates, with a height of15-40m, and consists of two or three sections. In the rectangular cavity at the bottom of the lifting rod lamp, in addition to the electrical control system, a lifting system such as a motor is also installed. The electric control system is installed inside the lamppost, which can avoid the failure of lifting action caused by bad outdoor environment.

The electric control system is equipped with various circuit overload protection devices. Copper-based silver plating is widely used as a conductor of circuits in the system to ensure good contact of electrical connections. The lifting system of the lifting rod lamp is to drive the lamp panel to lift through the motor, worm gear reducer (electromagnetic braking type), safety coupling, main steel wire rope, auxiliary steel wire rope, rope splitter and moving pulley block. Worm gear reducer has strong self-locking ability, compact transmission and large transmission ratio. In order to reduce the speed ratio and rising torque of the worm wheel and worm, a set of movable pulleys is specially added to make the vertical speed of the lamp board less than 0.2m/s. ..
