摘要

PURPOSE: A natural sunshade-and-daylight device is provided to promote energy efficiency by intercepting solar heat and utilizing sunlight as indirect illumination and to improve a users' condition by natural illumination. CONSTITUTION: A natural sunshade-and-daylight device comprises a high reflective illumination film(1) reflecting sunlight, an upper blind(2) attached onto the upper surface of the high reflective illumination film, a primary motor(3) controlling an angle of the upper blind, a lower blind(4) installed to be located to the lower part of the upper blind, a secondary motor(5) controlling an angle of the lower blind, a heat reflective film(6) installed to hangings to be located on the front of the upper blind, and a panel(7) where the primary and secondary motors are installed so that the upper and lower blinds revolves separately to intercept solar heat and to let partial sunlight in a room through the upper blind.
