The relationship between the installation height of solar street lamps and illuminance, road width, and road spacing and suggestions
Aug 03,2023
The installation height, illuminance, road width and road spacing of solar street lights are interrelated factors, which determine the lighting effect and coverage of solar street lights.When designing and installing solar street lights, these factors need to be considered comprehensively to meet lighting needs and ensure the safety of pedestrians and vehicles.Here are some suggestions:
Installation height: The installation height of solar street lights is usually related to factors such as street light power, lighting range and road width.Generally speaking, solar street lights with lower power are suitable for installation at lower positions, while street lights with higher power need to be installed at higher positions to ensure sufficient lighting range.According to experience, the recommended range of installation height is as follows:
Small roads, sidewalks: 3-5 meters
Normal urban roads: 6-8 meters
Main roads and expressways: 8-15 meters
Expressway: 15-25 meters
Illumination: According to the recommendations of the International Commission on Illumination (CIE), the illuminance of road lighting should be determined according to factors such as road type, traffic flow, and surrounding environment. Here are some suggested illuminance standards:
Residential roads: 5-15 lux
Commercial roads: 15-30 Lux
Main roads : 30-60 Lux
Expressway: 60-120 Lux
Road width and road spacing: The road width and road spacing of solar street lights should be determined according to factors such as road type, traffic flow, and installation height. Generally speaking, the larger the road width, the more street lights are required, and the higher installation height are need. As a rule of thumb, here are some suggested road spacings:
Small roads, sidewalks: 15-20 meters
General urban roads: 20-30 meters
Main roads : 30-40 meters
Expressway: 40-60 meters
It should be noted that the above suggestions are for reference only, and actual installation may need to be adjusted according to local regulations, climatic conditions and specific lighting needs. In order to ensure lighting effects and safety, it is recommended to consult professional lighting engineers or follow relevant national and industry standards when designing and installing solar street lights.
