1. What is building lighting:

Building lighting is also called urban lighting project. It refers to the treatment of landmark buildings in order to beautify the urban environment and improve the overall image of the city. , shopping malls, tourist attractions, streets and other places with high traffic for lighting.

2. The role of building lighting:

1. Highlight the faces and points of the city

In the city at night, the buildings in the central area of ??the city are relatively bright. Concentrated to form a building complex, the lighting density of the building complex is relatively large and the brightness of the light is high, and urban landmark buildings are often located in the central area. Neon advertisements, light box signs, internal lights and external lights of buildings, etc., make the central area a bright area embedded in the road network, making the structure of the city's central area clear at a glance. In other parts of the city, that is, the dots of individual lighting are more uniform, with smaller light density, lower brightness, and fewer types. They become the base of the urban lighting environment and play a supporting role.

2. Clear city outline

The outline of a city under the sun is determined by the shape, color and shadow of the buildings on its edge. The more well-organized the city, the better it is with the surrounding environment. The tighter the union, the harder it is to discern the city's outline. The urban lighting project at night clearly outlines the outline of the city, which is clearly different from the surrounding areas. When the city is viewed from a height at night, the outline is complete and clear, intuitively reflecting the shape and scale of the city.

3. Highlight the urban structure

The identification of urban structure, in addition to landform features, mainly lies in the identification of different areas formed by urban roads and building groups. The city under the sun reflects all the information of its components, and the urban structure is hidden in it, making it difficult to distinguish. At night, the secondary and ancillary parts of the city are blended together and become the black "bottom" part. The lighting design of the building emphasizes the main and essential parts of the city, becoming the bright "image" The part makes the urban structure stand out, easy to identify, and has both a sense of direction and a sense of layering and three-dimensionality.
