Urban lighting landscape and artistic lighting

1. The concept of urban lighting landscape and artistic lighting Since the beginning of the application of power supply, lighting technology has developed rapidly. Now, people have gradually divided the lighting technology into functional lighting and artistic lighting. Functional lighting is to provide the necessary illuminance in order to ensure clear vision; artistic lighting is to use light to create an artistic landscape that focuses on viewing. People have mature experience in how to correctly use lights to complete functional lighting tasks. And artistic lighting is an artistic lighting formed by the combination of natural science and aesthetics. On the one hand, it belongs to the category of natural sciences, including the re-understanding of the law of light phenomenon, and there is a trend of more in-depth research on its essence; on the other hand, the expression methods of the diversity of light and the process of aesthetic understanding belong to the environment The category of aesthetics, at present, this field is still in its infancy in our country. The primary task of artistic design is the expression of artistic themes and visual comfort. The illuminance of the light should change with the changes of the environment and artistic conception, and the designer needs to create according to his own artistic accomplishment and scientific and technological knowledge. It needs to pay attention to the aesthetic effect produced by the surrounding space environment and the psychological effect produced by it on people. Therefore, the lighting environment of all residential, entertainment, and social places should meet this requirement. It enables people to experience the high-grade visual enjoyment that combines modern urban lighting technology and art. 2. The main issues of urban environmental art lighting research (1) The nature, development and application of artificial light sources; (2) The nature, progress and application of the control system; (3) The synthesis of light and color and its relationship with the architectural environment Relationship; (4) The physiological and psychological effects of light and color on people; (5) The basic expression method of environmental art lighting; (6) Urban lighting environment planning and design methods; (7) Rationalization of urban lighting environment design documents And standardization; (8) the expression method of environmental art lighting design intent; (9) the control of light pollution and the standardization of the urban lighting environment; (10) the implementation of the urban lighting environment project. 3. Lighting design of urban environment art (1) The work of artistic lighting requires integrity and coordination. Although some lighting projects may be successful from a local (i.e. micro) perspective, they lack artistic connotation and rhythm in terms of the entire city’s night view (i.e. macro). The night landscape mainly relies on lighting for artistic creation. Then, how to appropriately represent the micro, how to deal with the artistic connection between the micro and the micro, and between the micro and the macro, requires an organized art of general lighting and the use of some government actions to determine the overall layout of the city. Set out, mobilize various artistic expression methods in an orderly manner to create the night scene of the city. The development of urban lighting landscapes, the planning and coordination of lighting environmental projects have become a trend, and they have also become an important part of urban construction and management. (2) The development and application of new light sources and lighting equipment provide a broad imagination and practice space for artistic lighting designers, becoming an important factor affecting the urban lighting environment and attracting people's attention. With the deepening of electronic technology and gas discharge research, various gas discharge lamp technologies with high power, high luminous efficiency, wide chromatogram, easy control, energy saving and safety are becoming more mature and more and more widely used. Take laser as an example. At present, although laser as an artistic lighting source has been used in entertainment venues such as dance halls, theaters, indoor and outdoor exhibitions and large-scale gatherings, its application is not very common due to the complexity of technology and equipment. In fact, lasers, like optical fibers and other new light sources, have only just begun to be applied in a large range, and they need to be continuously improved. These new types of lighting sources, which have not been widely used at present, will inevitably become common light sources widely used in the future, thus driving the improvement of lighting design ideas. (3) Compared with the past, designers nowadays have undergone tremendous changes in both design and actual operation. Modern control technology has become a huge driving force for the development of architectural environment art lighting. On the one hand, the computerization of design, calculation and rendering, especially the computer simulation of models and color effects, enables art lighting designers to create their own works in a realistic environment, adjust the overall design, and compare them to hand-drawn renderings. It is more realistic and detailed, can communicate with users more practically and is easy to modify the program; on the other hand, the development of automatic control technology also enables designers to create control effects and wonders in the design that have not been achieved in the past. The lighting landscape greatly enriches the artistic expression of lighting.
