Selection criteria of LED street lights for different road types

 

LED street lights are widely used in various types of road lighting due to their advantages such as high efficiency, energy saving and environmental protection. However, different road types have different lighting requirements, so many factors need to be considered when selecting LED street lights. This article will introduce the selection criteria of LED street lights for different road types in detail.

I. Urban main roads

Features: large traffic volume, fast speed and few pedestrians.

Selection criteria:

1. Power: Usually 150W-300W LED street lights are selected to ensure sufficient brightness and lighting range.

2. Installation height: The recommended installation height is 12-14 meters to cover a larger area.

3. Spacing: The spacing between street lights is generally 30-40 meters to ensure uniformity of lighting.

4. Light distribution: LED street lights with good light distribution should be selected to avoid glare and dark areas.

II. Secondary roads

Features: moderate traffic volume, slow speed and more pedestrians.

Selection criteria:
1. Power: Usually 100W-150W LED street lights are selected to meet lighting needs.
2. Installation height: The recommended installation height is 10-12 meters.
3. Spacing: The spacing between street lights is generally 25-35 meters.
4. Light distribution: LED street lights with uniform light distribution should be selected to ensure the safety of pedestrians and vehicles.

III. Branch roads and small streets

Features: small traffic volume, slow speed, and more pedestrians.

Selection criteria:
1. Power: Usually 60W-100W LED street lights are selected to meet basic lighting needs.
2. Installation height: The recommended installation height is 8-10 meters.
3. Spacing: The spacing between street lights is generally 20-30 meters.
4. Light distribution: LED street lights with soft light distribution should be selected to avoid light pollution to residents.

4. Sidewalks and pedestrian streets

Features: no motor vehicles, many pedestrians, frequent nighttime activities.

Selection criteria:

1. Power: usually choose 30W-60W LED street lights to provide appropriate lighting.

2. Installation height: the recommended installation height is 6-8 meters.

3. Spacing: the spacing between street lights is generally 15-25 meters.

4. Light distribution: LED street lights with uniform and soft light distribution should be selected to ensure pedestrian safety while avoiding light pollution.

5. Expressway

Features: large traffic volume, high speed, no pedestrians.

Selection criteria:

1. Power: usually choose 200W-300W LED street lights to ensure sufficient brightness and lighting range.

2. Installation height: the recommended installation height is 14-16 meters.

3. Spacing: the spacing between street lights is generally 40-50 meters.
4. Light distribution: LED street lights with concentrated light distribution should be selected to avoid glare and dark areas.

VI. Special areas

Features: Special areas such as bridges, tunnels, intersections, etc. have special requirements for lighting.

Selection criteria:

1. Power: Select the appropriate power according to specific needs, usually between 100W-200W.

2. Installation height: Select the appropriate installation height according to the specific environment.

3. Spacing: Adjust the spacing between street lights according to specific needs.

4. Light distribution: LED street lights with specific light distribution should be selected to meet the lighting needs of special areas.

In short, the selection criteria for LED street lights of different road types should comprehensively consider factors such as road characteristics, lighting needs, installation height, spacing and light distribution. I hope this article can provide you with valuable information to help you better choose LED street lights suitable for different road types.
