High-pole LED street lights generally refer to new lighting devices composed of steel column-shaped light poles over 15 meters and high-power combined light frames. The high pole led street light is mainly composed of the lamp holder, the internal lamp electrical, the pole body and the basic part. There are many types of high pole led street lights. According to different specifications, we divide high pole led street lights into the following types:

1. According to the height of the pole

1) Half height pole led street light

The height of the semi-high pole led street light is 16~18 meters, which can be regarded as a simplified small high pole led street light. Half-height pole led street lights are mostly fixed light stands or light panels, the lights are illuminated around, and 250, 400W high pressure sodium lamps or metal halide lamps are installed on the light stand.

Half-height pole led street lights are generally used in ordinary intersections, small and medium-sized interchanges, small and medium-sized squares, docks, etc. The lamp panel of the half-height pole led street lamp is small, the number of lamps installed is small, the irradiation range is small, and a lift truck is required for maintenance. If the lifting type is specified, the manufacturer can be required to install lifting equipment.

2) High pole led street light

The height of the light pole or lighthouse is 20 meters and above, and my country stipulates that the height of high pole lighting generally does not exceed 45 meters. Stadium light poles or lighthouses can be up to 50 to 72 meters high. The high-pole LED street lights used in square lighting project the light evenly around; the high-pole LED street lights used in sports venues or around major intersections, the lights are fan-shaped to one side. The lamp panel is a lifting type, a dumping type, and a fixed climbing type. Lamp power has 400, 600, 1000, 2000w and so on. The light sources include high pressure sodium lamps, metal halide lamps, etc.

2. According to the structure of the metal rod, it is divided into equal diameter rod and tapered rod. The tapered pole structure is light and reasonable, and the wind resistance is small, and it has become the mainstream of high pole led street light poles.

3. Classification according to the landing method of the lamp panel

1) Lifting high pole led street light. There are two ways to lift the lamp panel and lift the cage.

Light plate lifting: There is a lifting mechanism in the lamp pole, and the lamp plate can be lifted and lowered, which is convenient for lamp installation and maintenance. When the lamp plate falls, it occupies a small area and basically does not affect the traffic and municipal appearance.

Lifting cage lifting: The lifting cage cooperates with the inner lifting mechanism of the high-pole led street light, which can be raised to the lamp panel or fall to the ground. A lifting cage can be used for multi-base fixed high pole led street lights. The lift mechanism requires three-phase AC power.

2) Tipping type high pole led street light. The light pole has a rotating shaft near the ground. With the help of a special hydraulic lifting trolley, the light pole can be raised to a vertical position or tilted from the vertical position to the ground. Mechanical locking positioning is possible in the vertical state or after the inclined drop position. The structure of the light pole itself is simpler, and the lifting mechanism and the three-phase AC power supply are omitted. A hydraulic lift trolley can be used for multiple dumping high-pole LED street lights, and the maintenance of lamp bulbs is also more convenient. The use of dump-type high-pole LED street lights must have sufficient poles to fall on the site. When the poles fall, they cannot affect traffic and the normal life of urban people. It can be used in suburbs, squares, stadiums and other places.

The height of the lifting and tilting high-pole led street lights can be 20-50 meters. Individuals can reach 72 meters.

3) Climbing high pole led street lights (or lighthouses). Climbing (or lighthouse) high pole led street lights are 20-72 meters high, and the light pole support structure can be in the form of a metal cylinder or a truss. There is a climbing device inside or outside the light pole to meet the maintenance needs of the pole. Climbing high pole led street lights can meet the lighting needs of large areas, such as large stadiums, docks, squares and other places. Climbing high pole led street lights are less applicable. Lighthouses are often equipped with climbing devices.

4) Fixed high pole led street light. The lamp panel is fixed with the lamp pole, which is inconvenient to install and maintain, and has been rarely used.
