Floodlights can highlight the appearance of a building's outline, emphasize its different parts, and enhance the aesthetics and recognition of the building. In city squares, parks, amusement parks, zoos and other places, floodlights are used for lighting and decoration to enhance the artistic sense and aesthetic value of the environment. In exhibition halls, museums, art centers and other indoor places, floodlights are used to highlight the characteristics of exhibits, emphasize the colors and shapes of exhibits, and enhance the viewing experience.
