Abstract: A light-diffusing structure may include a plurality of light-diffusing cell units. Each light-diffusing cell unit is polygonal with a plurality of edges and corners respectively, and the light-diffusing cell units connect with others by the edges to form a light-diffusing panel. When the sunlight passes through the light-diffusing panel, the sunlight is diffused and converted to a uniformly balanced light source. The light-diffusing structure may further include a restricting unit to restrict the movement of the light-diffusing panel.

Abstract: The instant disclosure provides a retractable light-diffusing module installed between indoors and outdoors. The retractable light-diffusing module includes a plurality of light-diffusing structures and a plurality of connecting units. The plurality of light-diffusing structures are spaced from each other sequentially, wherein each of the plurality of light-diffusing structures comprises a light-transmitting box and a light-diffusing filler. The light-transmitting box comprises an accommodating space which is filled with the light-diffusing filler. Each of the connecting units is located between each two of the light-diffusing structures to connect the plurality of light-diffusing structures, thereby forming a flat light-diffusing panel. When the outdoor sunlight passes through the flat light-diffusing panel, the sunlight will be transformed into a uniform flat panel light source irradiating the indoors thoroughly.
