Abstract:
When daylighting into a building interior, this daylighting structure attenuates the brightness of a setting sun or a winter-time incoming light of small elevation angles, and causes the incoming light to be diffusely emitted toward the ceiling surface or into a deep portion of the indoor space domain regardless of the elevation angle thereof. An incoming light (E 20 ) of 20° in elevation angle is caused to be diffusely emitted toward the ceiling surface on the internal upper side of the building through the refraction and reflection actions mediated by a light-transmitting material mounted in a horizontal direction opening of a wall. The light-transmitting material comprises: an outdoor region curved surface wherethrough the incoming light is refracted and let into the interior of the light-transmitting material in a focused form; a lower side reflection surface internally reflecting the refracted incoming light; and an indoor region curved surface wherefrom the internally reflected light is refracted and emitted toward the ceiling surface in a diffused form. Also disclosed are the installation wherein the light-transmitting material is inclined from the illustrated horizontal state, and the installation of a plurality of the light-transmitting materials, each in upper and lower directions and left and right directions.

Claim (Index 1):
A daylighting structure formed of a light-transmitting material that is attached to a daylighting portion of a building and propagates an incident light from an outside to a ceiling surface of a building interior,\n the light-transmitting material comprising: an upper side incidence and emission curved surface that is formed of an outdoor region curved surface in which the incident light is refracted and incident to the inside of the light-transmitting material in a focused form, and an indoor region curved surface from which the internally reflected light of the refracted incident light is refracted and emitted toward the ceiling surface in a diffused form, the upper side incidence and emission curved surface extending in a longitudinal direction of the light-transmitting material in a state of projecting upward from an end portion toward a center side of a width direction of the light-transmitting material; and a lower side reflection surface in which the refracted incident light reflects and changes to the internally reflected light advancing to the indoor region curved surface of the upper side incidence and emission curved surface, the lower side reflection surface extending in the longitudinal direction of the light-transmitting material.
