Summary:PROBLEM TO BE SOLVED: To provide a light shelf structure capable of irradiating a ceiling surface with sunlight entering an indoor as even as possible even in a case where the incident direction of sunlight is inclined to a lighting window in a plane view.SOLUTION: A light shelf structure 1 includes a lighting window 12 provided on an outer wall 11, and a light shelf 13 provided on the outer wall 11 along a lighting window 12. The light shelf 13 reflects sunlight S in a reflection area 20 to introduce the light into an indoor through the lighting window 12, and irradiates a predetermined irradiation area 30 of a ceiling surface 15 of the indoor with the light. A vertical cross section in a direction parallel with the lighting window 12 of the reflection area 20 is such a wave shape that a parabolic shape expanding downward is continued. 【課題】平面視で太陽光の入射方向が採光窓に対して傾斜している場合でも、室内に採り入れる太陽光を天井面になるべく均一に照射できるライトシェルフ構造を提供すること。【解決手段】ライトシェルフ構造１は、外壁１１に設けられた採光窓１２と、外壁１１に採光窓１２に沿って設けられたライトシェルフ１３と、を備える。ライトシェルフ１３は、反射領域２０で太陽光Ｓを反射して採光窓１２を通して屋内に導入し、屋内の天井面１５の所定の照射領域３０を照射する。反射領域２０の採光窓１２に平行な方向の鉛直断面は、下方に膨出した放物線形状が連続する波形状である。【選択図】図４
