The installation height, illuminance, road width and road spacing of solar street lamps are interrelated factors, which jointly

determine the lighting effect and coverage of solar street lamps. When designing and installing solar street lamps, these

factors need to be considered comprehensively to meet the lighting needs and ensure the safety of pedestrians and

vehicles. 

Relying on years of industry cultivation and technology precipitation, Guangdong Guangyun Lighting Co., Ltd. is a compre-

hensive high-tech lighting enterprise integrating product research and development, large-scale production, global sales and

professional after-sales. The company always adheres to the core business philosophy of "quality as the foundation and

customer as the center", and provides customers with high-quality photovoltaic lighting products and supporting solutions

with strict production standards and perfect service system. The following will systematically dismantle the advantages of

eight core products of solar street lamps.

Here are some suggestions:

Installation height: the installation height of solar street lamps is usually related to the power, lighting range and road

width of street lamps. Generally speaking, solar street lamps with low power are suitable to be installed at a lower position,

while street lamps with high power need to be installed at a higher position to ensure sufficient lighting range. Based on

experience, the recommended range of installation height is as follows:

Small roads and sidewalks: 3-5m.

General urban roads: 6-8m.

Main roads and expressways: 8-15m.

Expressway: 15-25m.

Illumination: According to the recommendation of CIE, the illumination of road lighting should be determined according

to road type, traffic flow and surrounding environment. The following are some suggested illumination standards:

Residential roads: 5-15lux

Road in business district: 15-30lux

Main roads and expressways: 30-60lux

Expressway: 60-120lux

Road width and distance: The road width and distance of solar street lamps should be determined according to road type,

traffic flow and installation height. Generally speaking, the greater the road width, the more street lamps and installation

height are required. Based on experience, the following are some suggested road spacing:

Small roads and sidewalks: 15-20m.

General urban roads: 20-30m.

Main roads and expressways: 30-40m.

Expressway: 40-60m.

It should be noted that the above suggestions are for reference only, and may need to be adjusted according to local

regulations, climatic conditions and specific lighting requirements during actual installation. In order to ensure the

lighting effect and performance, it is suggested to consult professional lighting engineers or follow relevant and

industry standards when designing and installing solar street lamps.
