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. The retractable light-diffusing module may be installed adjacent to the indoor side of a window.
