1. Lack of overall grasp, the overall planning lags behind
A special plan for urban lighting is the key to ensuring the overall effect of road lighting and night scene lighting. At present, the city's night scene lighting construction lacks an overall plan, and most of the lighting management departments in various districts build it spontaneously, resulting in scattered night scenes throughout the city, without primary and secondary. And characteristics, the overall lighting effect is average. There is an urgent need for relevant departments at the municipal or district level to integrate urban functional lighting and landscape lighting, as a special plan for urban lighting to be unified and compiled, and rise to the height of legal documents to guide the construction of urban night lighting projects in the city.
2. Improper application of colored light, there is a certain amount of light pollution
Because of its speciality with strong emotional color, colored light has higher requirements for use, and it should be considered carefully in architectural landscape lighting. However, the night lighting of many buildings in our city uses colored light, and it is more chaotic, and there are not a few examples of lighting that are very incompatible with the style, function, color and environmental characteristics of the lighting object. In addition, with the rapid development of urban night scene lighting, the brightness of buildings and roads continues to increase. Due to the lack of strict control, some night scene lighting has caused light pollution, which interferes and affects people's normal rest.
3. Ignoring the concept of lighting energy saving and lack of time-sharing control methods
On the one hand, my country's electric energy is relatively lacking, and there are still insufficient power supply in many regions and cities. How to implement the concept of energy saving in night scene lighting is particularly important. The night scene lighting in our city has begun to take shape, but most of the projects lack time-sharing control methods. All lighting facilities are turned on on weekdays, general festivals and major festivals, resulting in a certain degree of energy waste. It is necessary to learn the relevant practices of advanced cities and implement corresponding time-sharing control measures in the engineering design stage.
