With the rapid development of building floodlighting, it has gradually become part of the architectural language and plays an important role in expressing architectural culture. Flood lighting has the characteristics that natural light does not have. The lighting design highlights the architectural culture through the changes of light and shadow.

The concept of architectural culture is relatively macro, or the architectural connotation of the relationship between people and society. The floodlighting design of the building focuses on this to create an atmosphere, so that the architectural culture can be reflected in the night scene lighting, so as to show the cultural personality and make the expression more vivid.
Compared with natural light, artificial light has stronger plasticity and controllability, and its light color is rich and varied. Therefore, the floodlighting design of the building has great flexibility and diversity in shaping the building and its surrounding space environment at night, and can enhance the image of the building at night, with strong iconicity and strong expressiveness.

Generally speaking, due to different architectural features, such as its own function, environment, cultural connotation, architectural shape, external materials, colors, etc., different flood lighting is determined. The floodlighting design of the building should combine the nature and characteristics of the building and its surrounding environment, and select the appropriate lighting method.
The use of light and color is one of the important ways for floodlighting to express architectural culture, and it plays a key role in shaping the image and atmosphere of a building and enhancing its appeal. Through the use of light color, the floodlighting design of the building reshapes a new expression that is different from the daytime of the building, bringing people a new emotional experience and increasing the charm of the building.
