“Up and down linear lighting effects”: This refers to the lighting design that illuminates both upward and downward directions, creating a visually appealing and balanced illumination.
“Increase the sense of spatial hierarchy”: This means that the lighting design enhances the perception of different levels or layers within the space, adding depth and dimension to the overall environment.
“Break the dullness brought about by unity”: This implies that the lighting effects prevent the space from looking monotonous or uniform, adding interest and variation to the visual experience.
In summary, the combination of up-and-down linear lighting effects enhances the spatial hierarchy, adding depth and complexity to the space while avoiding a monotonous and boring appearance.
