The invention discloses a basement light-storage dual-purpose device, and aims to solve the problems of equipment redundancy and resource waste caused by independent arrangement of a natural lighting system and a photovoltaic energy storage system in the prior art. The device comprises a light collecting assembly, a light guide splitter, a lighting component, a photovoltaic power generation unit, an energy storage unit and a control and power supply unit. The light collecting assembly is used for collecting natural light; the light guiding and splitting device is arranged below the light guiding and splitting device and distributes light to the lighting component and the photovoltaic power generation unit; the daylighting component guides part of light into a basement to achieve daytime lighting. The photovoltaic power generation unit converts the other part of light into electric energy and stores the electric energy in the energy storage unit; the control and power supply unit automatically controls the energy storage unit to supply power to the lighting lamp when the ambient light is insufficient. Through the integrated design, organic combination of natural light introduction and photovoltaic power generation energy storage is achieved, the structure is compact, energy consumption and cost are effectively reduced, and day and night continuous and energy-saving illumination of the basement is achieved.
