In the field of intelligent dynamic lighting design, the human subjective experience as a reflection of human-centered lighting design elements is the difficulty of research. The work aims to bring visual morphological cognition and spatial dimension as design elements into intelligent dynamic lighting design, exploring the spatial dimension elements in dynamic light environments and combining them with intelligent dynamic lighting design to change the user's visual morphological cognition of objects and environments by adjusting the contrasting relationship of spatial dimension elements. The characteristics of spatial dimensions were converted into design elements, clarifying the visual presuppositions of the design objectives, determining the visual principles of spatial dimensions, constructing the relationship between spatial dimensions and lighting, and applying them to the practice of intelligent dynamic lighting design. Through the use of intelligent dynamic lighting design methods with spatial dimension elements, the correlation and sense of contrast between spatial dimension and dynamic lighting are constructed to convey an innovative visual image of dynamic lighting and improve the user's satisfaction as well as the user's experience of dynamic lighting.
