  • Natural lighting apparatus and hybrid illumination system using same
    Patent number: 8905586
    Abstract: A natural lighting apparatus using sunlight is provided. The natural lighting apparatus includes a second light condensing device provided in a focal region of a first light condensing device to convert sunlight condensed in the focal region by the first light condensing device into straight parallel light rays through the second condensing device to provide sunlight having a high luminous flux to an indoor space. This natural lighting apparatus may be used together with an artificial illumination apparatus in a hybrid illumination system.

  • NATURAL LIGHTING APPARATUS AND HYBRID ILLUMINATION SYSTEM USING SAME
    Publication number: 20120091897
    Abstract: 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.
