PURPOSE: A buried-type natural lighting apparatus is provided to obtain sunlight regardless of a solar altitude by obtaining sunlight through a transparent panel when the solar altitude is high. CONSTITUTION: A buried-type natural lighting apparatus comprises lighting units(10) and fixing units. Each lighting unit comprises double transparent panels and a light reflecting panel. The light reflecting panel is inserted between the transparent panels. A light concentrating member and a light transmission member are formed on the bottom end of each lighting unit. The light concentrating member concentrates sunlight flowing through the transparent panels and the light reflecting panel. The light transmission member transmits the concentrated sunlight. The fixing units fix the lighting units. |
