This is a structural restraint as the core of the desktop lamp design. The lamp body is composed of a base, a column and a horizontal lamp arm. The shape is concise and clear, emphasizing the stable proportional relationship and clear force logic. The underside of the lamp arm forms a continuous luminous surface to provide direct and controllable working lighting. A single shaft meets the requirements of the foundation angle adjustment, while avoiding the interference of complex structures to the overall shape. The design deliberately reduces the sense of visual presence, so that the desk lamp is closer to a rational functional component in the desktop environment, rather than decorative objects, and remains quiet and durable under long-term use.
