ABSTRACT:
The present invention relates to a sunlight collection apparatus with increased sunlight gathering and receiving capabilities, which is cheap to produce and allows reliable collection of sunlight without having to track the sun. This sunlight collection apparatus has a light collection portion, facing toward the sun, for collecting sunlight; a light conducting portion, having optical fiber cables, for conducting sunlight collected by said light collection portion indoors; and a light scattering portion, provided at a tip of said light conducting portion, for lighting a room with sunlight conducted by said light conducting portion. The light collection portion has a plurality of lens elements arranged facing in the direction of the sun, with the front surface of each lens element which faces toward the sun having a curved surface. The lens elements have a tapered shape in a rearward direction from the front surface. A guide portion for guiding sunlight entering into the lens element is built into each lens element. This guide portion is coupled with an optical fiber cable from the light conducting portion.
