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.
