A chandelier refers to a high-end decorative lighting fixture suspended from the indoor ceiling. Pendant lights, whether hung with wires or iron supports, should not be hung too low, obstructing normal vision or making people feel glaring. Taking the chandelier in the dining room as an example, the ideal height is to create a pool of light on the dining table without obstructing the gaze of everyone on the table. At present, the hanging bracket of the chandelier has been installed with springs or height adjusters, which can be suitable for different heights of floors and needs. Interior design refers to the value-added preparation work of deepening the interior work of existing building spaces to meet certain construction purposes. Interior design is mainly based on the nature of the building's use, its environment, and corresponding standards, using material and technological means and architectural design principles to create a functional, comfortable, and beautiful indoor environment that meets people's material and spiritual needs.
