toothed blinds for daylight.

摘要

Window installation comprising light guiding blinds (40-43, 51, 52) have serrated upper sides at least partially molded into prism (54, 104), said prismatic molding being provided at least in the first portion of the blinds disposed close to the irradiation area and serving to reflect daylight, showing said teeth molded prismatic one side of the prism to school incidence and with a side reverse prism shown into the interior space and two edges of blinds each on the side of solar incidence forming an incidence plane and two edges of blinds each on the side of the interior space forming a deflection plane, and a connection line between the edge of a louver louvered plane in the plane of incidence and a blind edge adjacent upper blind in the plane forming an angle to the plane alphaS bending and irradiates Solar tion incident from the outside being reflected back as a pottery angle to the plane of incidence in the direction of the outer space, with the front side of solar incidence, said plane of said edges shutter being parallel to one another, characterized because a) the sides of the individual prismatic tooth shown to solar incidence have angles of inclination (a) relative to the horizontal, said angle (a1) substantially smaller in area radiation level and said angle being of angle (a2) greater than a greater distance from the plane of irradiation, b) the angles of inclination (a) of the sides of the individual tooth of the teeth (106, 107) displayed to the sun incidence increase either continuously or discontinuously or irregularly following a concave curved path increasing amounts starting from the radiation area to the interior space, and c ) On the upper side of the blinds light guide (40, 51) the reflected radiation is concentrated back (82) and a concentration zone (46, 53) is formed near the incidence plane said concentration zone ( 46, 53) which is disposed opposite to the shutter (42) in the plane of incidence and / or the underside of upper blind (52) behind the incidence plane, d) on the upper side of the shutter guide light (51, 41) radiation reflected light can be reflected back backwards in the individual teeth at an angle álfar alphaS.
