Zusammenfassung:The present invention relates to a natural lighting device for a basement, which receives natural light from the ground and irradiates the natural light to a basement. The natural lighting device for a basement comprises: a light receiving unit which is installed on the ground to receive natural light from the ground; an inducing unit which is coupled to the lower part of the light receiving unit and is extended to the basement to induce natural light to the basement; a lighting unit which is bent in one direction from the lower part of the inducing unit and is installed to be rotated to irradiate the induced natural light; and a rotary unit which is connected to the lighting unit and provides rotary driving force to the lighting unit. Therefore, the present invention irradiates natural light by rotating natural light received by the light receiving unit by a rotation unit in an underground lighting unit. Thus, an irradiation range of natural light in an underground space is extended, and at the same time installation costs of a natural lighting facility can be reduced by increasing irradiation efficiency of the lighting unit. 본 발명은 지상에서 자연광을 수광하여 지하에 조사하는 지하의 자연채광장치에 관한 것으로서, 지상에서 자연광을 수광하도록 지상에 입설된 수광부와, 이 수광부의 하부에 결합되되 지하까지 연장 설치되어 자연광을 지하로 유도하는 유도부와, 이 유도부의 하부에서 일방으로 절곡 형성되되 상기 유도된 자연광을 조사하도록 회전가능하게 설치된 조명부와, 이 조명부에 연결되어 조명부에 회전구동력을 제공하는 회전부를 포함하는 것을 특징으로 한다. 따라서 본 발명은 수광부에서 수광한 자연광을 지하의 조명부에서 회전부의 의해 회전시키면서 자연광을 조사함으로써, 지하공간에서 자연광을 조사범위를 확장시키는 동시에 조명부의 조사효율을 향상시켜 자연채광설비의 설치비용을 절감할 수 있는 효과를 제공한다.
