Research on brightness in city night scene illumination design

Lighting is an important symbol of modern city. To strengthen the construction of night view lighting, plastic one 'the city that never sleeps, has been the trend of the development of the current urban construction. Practice has proved that only overall planning of urban nightscape lighting project, scientific distribution, reasonable configuration, elaborate design, careful construction, strengthen management, to ensure that the overall effect and good effect. With wider range of city night scene lighting, the author discuss some views here.

a, unified planning is a fundamental premise of the construction of urban nightscape lighting.

city night scene lighting is the reorganization of the urban landscape lighting and color, show the city features, creating the cultural atmosphere, increasing urban charm. City night scene lighting is a science, is also an art, big to a city, small to a street, a monomer building, where the light up, what place should not be bright, night view lighting needs to be overall planning, overall consideration. In the night view lighting planning, in the city to detailed history, current situation and development prospect of serious investigation, and the key scenic spots, demonstrated in cognizance and then on the basis of the implementation. At the same time, the city night view lighting must also highlight the characteristics, exquisite taste. Light is a visual art, the visual effect of showing city characteristic is the 'soul' illumination. Therefore, style and taste is an important problem. Conforms to the landscape features, is rich in culture, there is a time spirit and noble elegant artistic style. To inhibit the landscape construction, advertising and other facilities, should be clean, make the landscape in harmony with the surrounding environment. In during the night view lighting construction, therefore, must be unified planning, choose accent lighting area and attractions, from a macro level prescribed illumination and lighting style, otherwise will not night view lighting the overall artistic effect.

2, elaborate design is an important part of urban nightscape lighting.

the first thing to prepare the technical scheme, which is the core of the engineering design, engineering quality, level, cost and time limit for a project such as the comprehensive embodiment of the indicators. As a lighting engineering design, usually should be arranged the following content: determination of intensity of illumination and intensity of illumination compensation coefficient; Choose illume way; The choice of light source and lamps and lanterns; The reasonable arrangement of lamps and lanterns; Intensity of illumination computation; Power supply system; Panel allocation and installation location; Distributor of electrical configuration; Walk pipe line; The determination of into line go line; Cable type and installation method; Line is calculated. Second to engineering design, in accordance with the requirements of technical solution, preparation of drawings directory; Draw the electric lighting circuit layout; Design of power supply system diagram; Electric lighting equipment and material list. All the lamps and lanterns, please indicate which switch, cable, power distribution equipment location, cable type, number and installation way, the wire length and the load. The active current and reactive current give necessary instructions, etc. Should be highlighted in the whole design work, targeted, advanced, innovative and feasibility. Targeted is the purpose of the project, function and function; Advanced, is engineering design must be given a lead, make engineering has the life and times feeling; Innovation is based on new technology digestion and absorption of innovation; Engineering design feasibility is refers to not only conform to the functional requirements, and in line with the social trends, should be both should be suitable for the status quo and development vision, and so on. Three, control cost is a key work of the construction of urban nightscape lighting.

the project cost is a composite index. Do a good job in street light engineering cost management to give full play to the role of the investment benefit is very important. Control the cost to run through the whole course of the construction of urban nightscape lighting.

1, starting from the design stage, the budget and design personnel according to the engineering general situation and the preparation of engineering budgetary estimate of investment, reasonable design, avoid the phenomenon of engineering budget exceeds the amount of investment.

2, strengthen the construction process of cost management. Choice of the economic and reasonable construction organization plan, reasonable decorate a process, to ensure the continuity of the construction and balance; Strict enforcement of rules for examination and approval of design changes, completes the concealed work, change the project visa, strictly implement material consumption quota, and strong evaporation, to reduce the material consumption, on the premise of ensure the engineering quality, deal with the use of the remaining material; Rational use of labor force, compression non-productive personnel, reduce the labor costs; Strictly enforce the using norm, improve the utilization rate of mechanical, maximize the mechanization level of operation.

3, well completion stage of cost management, according to the as-built drawings and final verification. To scientific and rational, practical and realistic, in strict accordance with the national documents and norm.
