Practice and Thinking on the Construction of Urban Night Scene Lighting Project

    When night falls, street lights meet the requirements of urban road lighting, but they cannot fully reflect the beauty of the city under the stars. A vibrant city is beautiful during the day and even more beautiful at night. It can not only reflect the city's economic development, but also reflect the city's material and cultural consumption levels. It is necessary to implement the night scene lighting project. Under the dynamic and quiet lighting rendering, the buildings are tall, majestic, dignified, simple and brilliant, the flowing water is shining, the bridges are like rainbows flying over the Milky Way, and the courtyards are like water and hibiscus. The beauty of the city is refreshing even at night.

    In the construction of urban night scene lighting, the operation and management should do a good job of "two highs" and "two lows" in terms of integrity, artistry, and energy saving.

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

    At the beginning, the overall layout is reasonable, the personality is outstanding and novel, and the combination of dots and lines, dynamics and statics, and heights and lows complement each other, reflecting the cultural heritage and characteristics, that is, the taste is high, as if looking back at him at the light fence. The second is to consider the harmony of day and night in the implementation of the project, not only consider the night view, but also consider the effect of the day. The installation of lamps should not be too many, not chaotic, try to be hidden, firm and safe, and achieve both bright and beautiful effects, that is, installation quality. It must be of a high level, and the daytime visibility and external integrity of buildings and other objects cannot be damaged by night lighting.

    2. To ensure low construction and operating costs 1. The investment in construction costs should be based on the size of the main body of the lighting building and the requirements of the investor as the starting point. If the construction cost is too large, it may be daunting for units that intend to implement lighting and lead to abandonment Lighting investment, therefore, the construction cost investment is comprehensively considered at the beginning, and the famous products with good product quality, safety and reliability are fully selected. Secondly, from the perspective of economy, reasonability and necessity, reasonable configuration of high-, medium-, and low-end price products, and a comprehensive analysis of the materials and construction budget of the lighting plan, so that the overall effect is 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 can be guaranteed to a large extent. Generally, there is a 1-2 year warranty and warranty period. To a large extent, it is ensured that no funds are invested to purchase products for replacement in the short term, and maintenance costs are reduced at the same time. Product energy consumption is the main aspect of reducing operating costs. If the product energy consumption is large, it will inevitably lead to an increase in operating costs, which may cause the lighting unit to be turned on only during the festival, and the purpose of lighting will not be achieved. 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 lamps, digital tubes, point light sources, light strips, spotlights, floodlights, wall washers, bulbs, etc., It has been widely used in urban night lighting, and its energy-saving efficiency is 50-70%. The original total lighting power of the Radio and Television Building is 75.8KW. After updating to LED lamps, the total power is reduced by 42KW compared to the same conditions. It is widely used in the lighting projects of Jinfeng Plaza, Sanonda Plaza, Street Light Bureau Building, Garden Bureau Building, Archives, and Industrial and Commercial Bank Building.

    Three, in the characteristics of city night lighting, it is necessary to do a good job of combining the two.

    Lighting should have different atmospheres, different styles, and different brightness. It must be grasped from the historical and cultural connotation, architectural style, and architectural form. It cannot be simply imitated to cause similarity. It must have a high artistic level, such as clothing and people, and people and clothing more beautiful, so that it can play a finishing touch. The first is to integrate with the architectural style. Jingzhou is the Chu cultural center in the capital of Chu State. The city wall was built in the Ming Dynasty. It cannot be simply illuminated with lights in the implementation. The colors should be yellow, warm white, and red as the main colors, and there should be time. The sense of distance or the mystery of history, the outer walls and roof are framed with yellow lights, and the wall is washed with light to make it have the distinction of reality and reality, with layers and lines. The second is to combine with the nature of the building. Each lighting area has its own characteristics and should be treated differently in order to improve the image of the city. The lighting of agencies and institutions generally uses static lamps to show solemnity and stability, and the main body of the lighting is majestic and tall, dignified and harmonious. Hotels are based on luxury and elegance, commercial venues are styled with active and dynamic changes, and scientific research units use rational and calm characteristics to brighten the distinction between main streets and residential areas to prevent light pollution. Modern high-rise buildings mostly use glass and granite as exterior walls, and the light absorbed by glass is not obvious. The granite exterior wall is supported by steel structure, and granite is glued to the steel structure. Drilling and installation damage the main surface of the building, which is not suitable. get on. For the above conditions and conditions, the design and construction must select the light source and light color in a targeted manner, and match it reasonably. It is advisable to use the upper and lower column projections to perfectly reflect the exterior and connotation of the lighting building.

    Urban lighting brings the city into motion and excitement, and the bustling night sky of the city is brilliance.
