Solar street light city lighting
Street lights along the urban road provide a safe and comfortable artificial luminous environment for people, which meets people’s demand, encourages people to go outside at night and thus leading to more urban activities. The quality of artificial luminous environment and people’s feeling mainly depend on illuminance, dazzle control and photochromism of the street lights. Urban road lighting design not only affects the appearance of a city, but also affects urban residents’ livelihood. Therefore, designers should take all aspects of factors into consideration when planning and designing the urban road lighting. Only in this way can we promote the development of modern cities. We will talk about how to plan and design the urban road lighting in a scientific and reasonable way in this article.
The staff should pay attention to the project environment when designing the street light circuits. Besides, staff need to ensure that the transformer is capable of meeting electricity demands of all the facilities. What’s more, the builders should pay attention to the public facilities along the roads when laying the cables. Generally, the low-voltage cables are buried underground through direct burial way, which can not only ensure the normal operation of the cables, but also protect the green belt from damage.
As we mentioned before, the functions of urban road lighting are more than providing lighting for people. It is also a part of urban landscape. Therefore, the aesthetic lamp are chosen in the planning and design of urban road lighting systems. At present, the light sources used in road lighting mainly include high-pressure sodium lamps, metal halide lamps, LED lights and electrodeless lamps. All of the light sources have their own characteristics.
Designers should make reasonable choices based on road functions and the requirements of the national green lighting plan, so as to not only meet the requirements of road lighting standards, but also achieve the goal of energy saving and emission reduction. The choice of light source should also meet the following two requirements: one is to meet the road illumination requirements, and the other is to meet the power density value requirements. Therefore, the designer should select the appropriate light source on the basis of comprehensive consideration of various factors.
In modern city, the factors to consider of road lighting circuit design are not just illumination and power supply. Based on the goal of saving energy, the design of urban road lighting circuits serves for lighting time control of the street lights. The staff can use the computer terminal to monitor the lighting condition of street lights in real time in the urban area where the intelligent control system has been installed. For other areas, manual inspection is adopted to adjust the lighting time. As China's road transportation facilities are relatively complete and urban road lighting circuits are buried underground, overall planning must be taken into account when designing urban road lighting circuits. Designers should make a comprehensive assessment of urban road lighting circuits from two aspects.
