Practice and Reflection on the Construction of Urban Night Lighting Engineering

1、 To achieve "high grade and high quality" in design.

Firstly, the overall layout is reasonable, with a prominent and innovative personality. The combination of dots and lines, the combination of movement and stillness, and the staggered high and low complement each other, reflecting cultural heritage and characteristics. That is, the taste should be high, like looking back at him at the dimly lit fence in old age. Secondly, in the implementation of the project, it is necessary to consider the harmony between day and night, not only considering the night scenery, but also the effect during the day. The installed lamps should not be too many or disorderly, and should be concealed as much as possible, firm and safe, achieving a bright and beautiful effect. That is to say, the installation quality should be high, and the visibility and external integrity of the building and other objects during the day should not be damaged due to night lighting. In the night lighting construction of Jingzhou Jinfeng Square and Dongmen Ancient City Wall, the city wall is an ancient city wall, the city tower has not been repaired for many years, and the bridge guardrail is severely weathered. In terms of light source, materials, and installation technology, LED new light source wall washing lamps, light strips, and energy-saving lamps are used, with low power and high brightness. The Juzheng street lamp is an antique bell shaped lamp, using lightweight materials with colors similar to the ancient city. During construction, adhesive or fixing on the new wall is preferred. Lightweight materials with colors similar to the ancient city are used for the bridge edge and water surface. Adhesive or fixing on the new wall is preferred during construction. LED seven color digital tubes are used for the bridge edge and water surface, and the colored light flows rhythmically on the water surface. Trees are illuminated by green and yellow floodlights. Clear and hazy layers are distinct, making the lighting project complement the landscape as a whole.

2、 Ensure dual low construction and operation costs

1. The investment in construction cost should be based on the size of the main body of the lighting building and the requirements of the investor. If the construction cost is too high, it may make units interested in implementing lighting feel intimidated, leading to giving up lighting investment. Therefore, the investment in construction cost should first be comprehensively considered, and high-quality, safe and reliable famous products should be fully selected. Secondly, from an economic, rational, and necessary perspective, reasonably allocate high, medium, and low-end price products, comprehensively analyze the materials and construction budget of the lighting scheme, and make the overall effect both economical and beautiful.

2. Operating costs: Product quality, energy consumption, and maintenance costs are the main components of operating costs. When selecting products, the quality of well-known brands is largely guaranteed, usually with a 1-2 year shelf life and warranty period, which largely ensures that no funds are invested in purchasing products for replacement in the short term, while reducing maintenance costs. Product energy consumption is the main aspect of reducing operating costs. If a product consumes a large amount of energy, it will inevitably lead to increased operating costs, which may result in lighting units only being turned on during holidays and not achieving the lighting goal. According to the national energy conservation and emission reduction plan, LED lighting technology has developed rapidly in recent years. As a new type of solid-state green light source, LED street lights, digital tubes, point light sources, light strips, spotlights, floodlights, wall washers, bulbs, etc. have been widely used in urban night lighting, with an energy-saving efficiency of 50-70%. The original total lighting power of the radio and television building was 75.8KW, and after being updated to LED lamps, the total power has been reduced by 42KW compared to the same conditions. Widely used in the night lighting projects of Jinfeng Square, Shalongda Square, Street Lamp Bureau Building, Landscape Bureau Building, Archives, and Industrial and Commercial Bank of China Building
