Analysis of night lighting of urban buildings

In modern cities, the beautification of lighting art in the environment and construction is very beneficial. This is because the good lighting environment not only provides good visual conditions for people's work, study and life, but also utilizes the styling of lamps and the coordination of light colors to make the building outline and environment reach a certain atmosphere and artistic conception, reflecting a certain style. Increase the beauty of the environment and architectural art, so that the environmental space is more in line with people's aesthetic requirements, and thus enjoy the beauty. Artificial lighting in any environment and building must meet the visual function requirements and meet the aesthetic requirements of people. Therefore, using the expressive power of light to carry out artistic processing on the environment and architectural space, subtly applying modern lighting technology and the artistic laws of light, fully expressing the urban environmental cultural information and architectural aesthetics, so that the artistic creation of urban builders can obtain the unique effect of artistic conception. .

The color design of urban architectural lighting requires that the color requirements of the night lighting renovation of buildings should be clear, rich and harmonious. The vivid color gives people a strong stimulation of the vision, which is easy to cause beauty, attract people's attention, and the bright neon lights have such an effect. Richness is the second requirement of color, which gives people a full and long-lasting beauty. Even if the color is vivid, if it is very monotonous, it is boring and causes people to get bored. Harmony and unity is the highest requirement for color beauty. To achieve harmony and unity of various colors, it is necessary to pay attention to setting a tone, and all colors must obey this tone. In addition, to properly handle the matching of similar colors and complementary colors, the similar colors are arranged in an orderly manner, which can achieve a harmonious effect.

The effect of urban architectural lighting design requires great flexibility and diversity of building lighting. Due to the different functions, cultural connotations, environment, architectural style, exterior finish color, and new and old materials of each building, The choice of lighting color, lighting, projection direction and lighting equipment also vary greatly. The brightness and color of the object to be photographed should be different from the surrounding environment and harmonious. Using artificial light to suppress, looming, virtual and static, and controlling the angle and range of light projection to establish the composition order and rhythm of light, can greatly enhance the effect of spatial changes, improve the spatial proportion, limit the space field, and emphasize the fun center. Increase the spatial level and clear the spatial orientation. For example, the night illumination of the government office building, the night lighting of commercial streets and entertainment venues, the night lighting of ancient buildings and modern buildings, the requirements and methods are not the same.

The nightscape of tall buildings requires a majestic, spectacular and imposing night scene. The night illumination of commercial buildings should be colorful and radiant, creating a bustling and lively atmosphere to attract more customers and stimulate people's shopping fun; for leisure venues, such as the pavilions of the street park, the night view of art pieces Lighting requires the creation of an artistic scene to provide visitors with a good nighttime leisure and entertainment light environment.

Urban architectural lighting design methods and methods 3.1 Facade floodlighting (flooding) lighting Projection lighting is the use of floodlights to directly illuminate the facade of the object and reshape its image at night. This is the most widely used lighting method in urban night lighting. The lighting effect not only shows the whole picture of the building, but also has a great advantage compared with the shearing force drawing using the shear force equation. Using the shear force equation to draw the shear force diagram under the complex load, the beam must be segmented and the respective shear force equations must be listed. The shear force value of each beam starting and ending point must also be calculated, and then the shear force diagram should be drawn. Obviously, this method is very cumbersome to draw the shear force diagram, but the load-running method saves a lot of complicated links. The drawing steps can be completely unnecessary, and the drawing can be done directly, which is very simple and intuitive.
