In the construction of modern urban infrastructure, the selection of the installation location of street lamps is a complex and critical link, which is affected by many environmental factors. Topography and landform are the primary factors affecting the installation of street lamps. The undulations of the terrain, the steepness of the slope, and the distribution of surrounding vegetation will affect the propagation of light and the lighting effect to a certain extent. In hilly or mountainous areas, the height and installation angle of street lamps need to be precisely adjusted according to the terrain changes to ensure that the light can effectively cover the traffic area of ​​pedestrians and vehicles. Especially on ramps, the inclination angle of the lamps needs to be reasonably designed to avoid insufficient lighting caused by terrain obstruction. In addition, the surrounding trees and other plants will also significantly affect the lighting effect of street lamps during the growing season, and the obstruction of leaves may lead to a decrease in light intensity.
Climate conditions are also an important environmental factor affecting the installation location of street lamps. The climate characteristics of different regions, such as precipitation, wind speed, temperature and humidity, will have a profound impact on the design and installation of street lamps. In rainy or humid areas, the electrical part of the street lamp needs to have good waterproof performance to prevent short circuits or failures caused by moisture intrusion. At the same time, in areas with high wind speed, the structural design of street lamps and their installation methods must take into account wind resistance to ensure stability and safety under adverse weather conditions. Corrosion-resistant materials should be selected during design to cope with the corrosive effects in humid environments and extend the service life of street lamps.
The humanistic environment also plays an indispensable role in the selection of street lamp installation locations. The city's cultural background, architectural style, and historical relics will have an impact on the design and layout of street lamps. In historic urban areas, the design of street lamps should be coordinated with the surrounding architectural style to maintain the overall beauty and cultural atmosphere of the city. In these areas, it may be necessary to choose street lamps with traditional styles to enhance the city's cultural identity. In addition, the installation location of street lamps should also fully consider the activity patterns of the surrounding flow of people, especially during holidays or special events, the layout of street lamps should be able to meet people's lighting needs, thereby improving safety. In some areas with frequent cultural activities, the brightness and color temperature of street lamps can also be adjusted appropriately as needed to create a more comfortable atmosphere.
