摘要： 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 (E20) 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 (1) mounted in a horizontal direction opening (4c) of a wall (2a). The light-transmitting material (1) comprises: an outdoor region curved surface (1b) wherethrough the incoming light (E20) is refracted and let into the interior of the light-transmitting material in a focused form; a lower side reflection surface (1d) internally reflecting the refracted incoming light; and an indoor region curved surface (1c) wherefrom the internally reflected light is refracted and emitted toward the ceiling surface in a diffused form; a mirror portion for generating the internally reflected light in a side surface (1e), (1e') of the longitudinal direction of the light-transmitting material. Also disclosed are the installation wherein the light-transmitting material (1) is inclined from the illustrated horizontal state, and the installation of a plurality of the light-transmitting materials (1), each in upper and lower directions and left and right directions.

摘要： A compact PAPI having a semiconductor light source and finely distribution of lights is herein proposed. The novel PAPI includes two artificial light sources each with a plurality of semiconductor emitters as well as two concave and two planar reflectors, one for each artificial light source. The concave reflectors collect light emitted by the plurality of semiconductor emitters of the first and second artificial light sources and gather the collected light to the planar reflectors as output of the PAPI.
