SOLAR TRACKING REFLECTION AND DIFFUSION PANEL APPARATUS FOR MAXIMIZED INDOOR NATURAL LIGHTING, AND ROOFTOP SUN SHEEN SUNLIGHT LIGHT SHELF APPARATUS USING THE SAME

摘要

A solar tracking type apparatus for maximizing indoor distribution and diffusion of natural light and a rooftop installation type optical shelf apparatus using the same are provided. The reflection panel apparatus has a plurality of reflection panels used for reflecting the sunlight in a rotation or a fixed type. In case of the rotation type, a ring-shaped lower circular frame supports both end units of the reflection panels while in case of the fixed type, a cover supports the both end units of the reflection panels. In both the rotation and fixed types, an angle control driving unit controls an angle through a driving wire which is combined to the reflection panels. In case of the rotation type, a rotation driving unit rotates the lower circular frame in a horizontal direction based on the center of the lower circular frame to control the angle. The natural light guided into the indoor through the reflection panels of which direction and angle are controlled is diffused through a white light diffused panel which is coated by a high-reflectivity material such as barium sulfate so that the uniform illumination can be maintained in the indoor.
