NATURAL LIGHTING APPARATUS AND HYBRID ILLUMINATION SYSTEM USING SAME

WIPO Patent Application WO/2010/147424

A2

The present invention relates to a natural lighting apparatus using sunlight, and more specifically, to a natural lighting apparatus using sunlight, wherein a second light condensing member is formed in the focal region of a first light condensing member so as to convert the sunlight condensed in the focal region through the first light condensing member into straight parallel light rays such as a laser beam through the second light condensing member, thereby being capable of supplying the sunlight of a high luminous flux indoors. In addition, the present invention relates to a hybrid illumination system which uses the natural lighting apparatus together with an artificial illumination and makes the utmost use of the natural lighting apparatus, thereby enabling the saving of energy.
