PURPOSE: A natural lighting apparatus for deep space lighting is provided to use sun light as a natural light source for a building lighting to minimize not only power consumption, but also carbon dioxide emissions, thereby protecting the atmospheric environment. CONSTITUTION: A natural lighting apparatus(A) includes a light collection device(1) which consists of a first light collection and reflection unit(11) and a second light collection and reflection unit(12), where the first and the second light collection and reflection units are mutually faced and tilted on the exterior of a top story of a building, and mutually interlocked by a solar tracker; and a light guiding device, where the collected sunlight from the second light collection and reflection unit of the light collection device is received through a prism panel(22) which is installed on the opening of the upper side. The collected sunlight, which is received through the prism panel, is guided through an irradiation unit of a light guiding pipe(21), which a prism film is attached to the inside, to the indoor space; and is then irradiated. |
