Night scene lighting is a key aspect of urban beautification. Through the change of lighting and the changing style of lamps, the overall visual point of view shows a lively and vivid city beauty.
(1) A complete night scene lighting design scheme usually consists of the following 10 parts.
①Analysis of the geographical environment of the building and determination of the main viewpoints for viewing;
②Analysis of the functions and characteristics of buildings;
③The overall concept of night scene lighting and the determination of key lighting parts;
4. Selection of the illumination or brightness level of the main supplementary surface;
⑤ Selection of lighting methods, lighting equipment (light sources, lamps and electrical accessories, etc.) and lighting colors; light sources should be selected according to the principles of high efficiency, long life, and appropriate color rendering index; lamps should be selected according to the appropriate light distribution curve, protection level, and economy. , The principle of appearance coordination is selected; electrical appliances are selected according to the principles of power saving, stability, high efficiency and durability;
⑥ Determination of the lighting scheme and the installation position of the lamps (including the design of the lamp frame);
⑦ Use the calculation of the number of light sources and lamps;
⑧ Design of lighting electrical control system and safety measures;
⑨Project budget;
⑩The final lighting effect and the drawing of the color rendering.
(2) Overcome the tendency to ignore daytime views and safety
It is often said that urban night lighting facilities are for viewing the scenery during the day and viewing the lights at night. Some night scene lighting projects have good lighting effects at night, but during the day, whether it is the shape, color and material of the lamps or lamp brackets, they are shoddy and unattractive, and are very incompatible with the building and the surrounding environment. Some lamp positions are installed at a very low height, or even placed directly on the ground, and some power lines are pulled randomly. These are all tendencies that must be noted and overcome.
(3) Overcome the tendency to only focus on festivals and ignore weekdays
It is beyond reproach to attach importance to the lighting of night scenes during festivals or major political events. But urban night lighting is not just built for a few festivals. Over the years, the lighting of urban night scenes has often been festive, and it is still dim after the festival. We say to take into account the lighting effect on weekdays, not to ask for the bright lights every day like the festival. At present, Beijing, Shanghai, Tianjin, Shenzhen and other cities have controlled lighting according to the levels of weekdays, general festivals and major festivals. At present, except for festivals, the night scene lighting is turned on the night before the weekend every week. However, there are still many cities that cannot do this, for many reasons, one of which is limited by electricity and financial resources.
(4) Overcome the tendency to re-build, neglect maintenance and management
At present, the construction of night scene lighting projects is the same as other project constructions, and the maintenance and management work after the completion of the project is generally neglected, so that some projects have not been used for a long time, the building outline lights are disconnected, some floodlights are not bright, and the bright ones are also due to the lamps and lanterns. Dust contamination, totally ineffective, doesn't work. Paying attention to and strengthening the maintenance and management of night scene lighting projects has become an important issue that needs to be solved urgently by the current night scene lighting construction and management departments.
