Japanese Patent JP2013112950
Kind Code:

Abstract:

To make manufacture of a light incidence adjustment member arranged at an indoor daylighting part simple and efficient, and to increase the degrees of freedom of the properties, material, and shape of an upper surface of the light incidence adjustment member.

A light incidence adjustment member 2 in an east-west wing shape (a triangular east-side flat plate part 2a and west-side flat plate part 2b) is arranged at a daylighting part 1a. End parts C, B, and D of base sides 2e, 2f of the light incidence adjustment member 2 are at the same height. The east-side flat plate part 2a and west-side flat plate part 2b rise from base sides 2e, 2f sequentially to the south direction and also rise from a border side 2c sequentially to the east direction and west direction. An end part A is the highest point. Part of high-altitude sunlight in the daytime is reflected on an upper surface of the light incidence adjustment member and not made incident on the daylighting part 1a, and low-altitude sunlight from the east or west direction is reflected on a lower surface of the light incidence adjustment member and made incident on the daylighting part 1a. Also disclosed are a light incidence adjustment member using a curved plate and a light incidence adjustment member having two upper and lower stages in similar shapes (the lower stage being small).
