Abstract:
PURPOSE: A natural lighting apparatus and a hybrid lighting system thereof are provided to improve optical transmission efficiency by changing sunlight into linear parallel light. CONSTITUTION: A natural lighting apparatus comprises a first and a second light-collecting members(10,20) and an optical transmission member. The first light-collecting member reflects sunlight to a focal region. The first light-collecting member is an envelope shaped concave back mirror. The second light-collecting member is arranged in the focal region of the first light-collecting member in order to change the sunlight into forward travelling collimated light. The second light-collecting member is an envelope shaped convex reflection mirror. An optical transmission member transmits the forward travelling collimated light to the inner space.
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.
Abstract:
The present invention relates to a solar light condensing system for realization of natural lighting, and more particularly, to a vertical solar light condensing system which is formed on an outer wall of a building using a reflective member and a light condensing member so as to secure large light condensing area and to increase light condesing efficiency.
