LED street light power, pole and height and road width

There are various types of street lamps. According to the light source, LED lights can be divided into LED street lamps, induction lamps, energy-saving lamps, high-pressure sodium lamps, metal halide lamps, etc. According to the occasion, they can be divided into ordinary street lamps, high-post street lamps, courtyard street lamps and landscape street lamps. Others can be divided into single-arm street lights, dual-arm street lights, combined street lights, solar street lights, and so on.

Second, street light source

The street light source has LED light, induction lamp, ordinary energy-saving lamp, high-pressure sodium lamp, metal halide lamp, etc. Which kind of street light source is good? Metal halide lamps and ordinary energy-saving lamps are not costly, have a long service life, and are easy to maintain. However, such street lamps have relatively high power consumption and are not recommended. High-pressure sodium lamps have a good fog-passing performance and are a type of street light source commonly used in the past. However, its life and energy efficiency are relatively poor, so the street light source is not recommended to choose high-pressure sodium lamp; the electrodeless lamp is also a kind of energy-saving lamp, the theoretical life is also quite long, but the cost is high, the maintenance is not easy, such light source is not recommended; Street light LED light source is the most used light source in recent years, high efficiency, energy saving, environmental protection, long life, convenient maintenance, and the price is not expensive, and many countries and regions are vigorously promoting LED, street light source selection recommended LED, LED street light is the road Lighting is preferred.

Third, the street light interval

The street lamp spacing is also the street lamp spacing, which is determined by various factors such as the lighting power of the street lamp, the height of the street lamp, and the width of the road. The street lamp spacing is typically 3.8-4 times the height of the pole. The longitudinal spacing of street lamps is generally 30 meters to 50 meters. When there are power poles or other poles, the spacing is 40 meters to 50 meters. Try to combine the power supply pole with the lighting pole to save investment. If the underground cable is used for power supply, the spacing should be small, which is conducive to the uniformity of illumination, and the spacing is usually 30 meters to 40 meters.

Fourth, the height of the street light

The height of the street lamp (the height of the street lamp pole) is generally 6 meters, 8 meters, 10 meters, 12 meters, 15 meters, etc. The specific use of the street light height depends on the width of the road surface. Generally, if the single side light is on, the height of the street light is the same as the width of the road surface. Or the height of the street light is less than 1 meter of the width of the road. The relationship between the common LED street lamp power and the pole height is generally: 30~60W street lamp height is less than 6 meters, 60~100W street lamp height is below 8 meters, and 100~150W street lamp height is below 10 meters.

5. About the street lamp

The street lamp management office is a sub-disciplinary full-budget institution. The main responsibility is to be responsible for the planning, construction, management and maintenance of county road lighting. It is responsible for the lighting management of public places and scenic spots in the county, and is responsible for the energy-saving utilization of road lighting products. The county roads are brightened and the supporting construction of buildings (structures) and the construction of street lamps in towns and towns.

Six, LED street light manufacturers

According to the statistics of global LED street lamp installations in 2014, the current global installation of street lamps is about 200 million 盏, of which about 65 million 欧洲 in Europe, accounting for more than 30%, and about 44 million 美国 in the United States, accounting for more than 20%. About 4 million baht, China is about 33 million baht, accounting for more than 16% of the world.
