Description

本発明は、上方に開いた建屋採光部における朝夕の太陽高度が低い時間帯の採光性能の向上化を図るための採光装置に関する。   The present invention relates to a daylighting device for improving daylighting performance in a time zone where the solar altitude in the morning and evening is low in a building daylighting section opened upward.

特に、建屋採光部の対向周縁部に配設される朝方太陽光反射板(夕方太陽光位置側)および夕方太陽光反射板(朝方太陽光入射側)として、それぞれ内側反射面を備え、かつ、建屋採光部への配設後の長手方向における高さの変化が互いに逆の関係となる反射板を用いた採光装置に関する。   In particular, as a morning sunlight reflecting plate (evening sunlight position side) and an evening sunlight reflecting plate (morning sunlight incident side) disposed on the opposite peripheral edge of the building lighting section, each has an inner reflection surface, and The present invention relates to a daylighting apparatus that uses a reflecting plate whose height changes in the longitudinal direction after being arranged in a building daylighting unit are opposite to each other.

これら朝方太陽光および夕方太陽光に対する各反射板の「長手方向における高さの変化が互いに逆の関係となる」とは、概略、例えば直角三角形状の朝方太陽光反射板が南側から北側の方向に沿って高くなり、かつ、同じく直角三角形状の夕方太陽光反射板が当該方向に沿って低くなっていることである。   “The change in height in the longitudinal direction is opposite to each other” of each reflector for morning sunlight and evening sunlight is an outline, for example, the morning sunlight reflector in the shape of a right triangle is in the direction from the south side to the north side. And the evening sunlight reflecting plate having a right triangle shape is also lowered along the direction.

すなわち直角三角形状の朝方太陽光反射板および夕方太陽光反射板が、それぞれの高さを決める斜辺部分がいわば互い違いとなるように対向配設されることである。   That is, the morning sunlight reflecting plate and the evening sunlight reflecting plate having a right triangle shape are arranged so as to face each other so that the hypotenuses that determine the respective heights are alternately arranged.

このような直角三角形状を含む後述の各種形状からなる朝方太陽光反射板および夕方太陽光反射板の配設状況では、その一方の高部分と他方の低部分とが対向している。   In the arrangement of the morning sunlight reflecting plate and the evening sunlight reflecting plate having various shapes described later including such a right triangle shape, one high portion and the other low portion face each other.

朝方太陽光の一部は夕方太陽光反射板の低い部分の上方からその対向側の朝方太陽光反射板の内側反射面へと進み、そこでの反射光が建屋採光部へ入射する。   Part of the morning sunlight travels from above the lower part of the evening sunlight reflector to the inner reflection surface of the opposite morning sunlight reflector, and the reflected light enters the building lighting section.

また、夕方太陽光の一部は朝方太陽光反射板の低い部分の上方からその対向側の夕方太陽光反射板の内側反射面へと進み、そこでの反射光が建屋採光部へ入射する。   Further, part of the evening sunlight travels from above the lower part of the morning sunlight reflecting plate to the inner reflection surface of the evening evening sunlight reflecting plate on the opposite side, and the reflected light enters the building lighting section.

例えばホテルの客室などでは、一般に日中の採光はさほど重要でなく、チェックイン後の午後の遅い時間帯およびチェックアウト前の午前の早い時間帯の採光性能が特に重要となってくる。   For example, in a guest room of a hotel, daylighting is generally not so important, and daylighting performance in the late afternoon after check-in and early morning in the morning before checkout is particularly important.

本発明は、このように朝方太陽光および夕方太陽光それぞれを同様に、光ダクトやトップライトなどの建屋採光部へ入射させることを志向した採光装置である。   The present invention is thus a daylighting device that is intended to make each of morning sunlight and evening sunlight enter a building lighting section such as a light duct or toplight in the same manner.

本明細書における東西南北はそれぞれ、北半球において本件採光装置を配設するときの方角を示している。南半球においては勿論「南北」の関係が逆になる。   In the present specification, east, west, north, and south respectively indicate directions when the daylighting device is disposed in the northern hemisphere. In the southern hemisphere, of course, the “north-south” relationship is reversed.

従来、上方に開いた長方形状の建屋採光部の周縁部分に太陽光反射板を設置した採光装置が提案されている(例えば特許文献1の図2参照)。   Conventionally, there has been proposed a daylighting apparatus in which a sunlight reflecting plate is installed on the peripheral part of a rectangular building lighting part opened upward (see, for example, FIG. 2 of Patent Document 1).

この太陽光反射板は、同じ高さからなる起立平板形状のものであり建屋採光部の例えば南側周縁部分に設けられて、そこでの反射光が光ダクトに入射するようになっている。   This sunlight reflecting plate is an upright flat plate having the same height, and is provided at, for example, the southern peripheral portion of the building lighting section, and the reflected light is incident on the optical duct.

特開平11−203917号公報Japanese Patent Laid-Open No. 11-203917

本発明は、太陽光反射板を建屋採光部の対向周縁部(夕方太陽光位置側および朝方太陽光位置側)のそれぞれに、当該反射板の長手方向における高さの変化が上述のごとく互いに逆の関係となる形で配設して、朝夕の太陽高度が低い時間帯にいわば特化した形の採光性能向上化を図ることを目的とする。   According to the present invention, the solar light reflectors are opposite to each other at the opposite peripheral portions (the evening sunlight position side and the morning sunlight position side) of the building lighting part, as described above, with respect to the height change in the longitudinal direction of the reflection plate. The purpose is to improve the daylighting performance in a specialized form in the time zone when the solar altitude is low in the morning and evening.

すなわち、夕方太陽光反射板(朝方太陽光位置側)の低部分上方などから朝方太陽光反射板(夕方太陽光位置側)の内側反射面へと進んだ朝方太陽光の反射光を建屋採光部に入射させ、かつ、朝方太陽光反射板の低部分上方などから夕方太陽光反射板の内側反射面へと進んだ夕方太陽光の反射光を建屋採光部に入射させることにより、朝夕の採光性能向上化を図っている。   That is, the reflected light of morning sunlight that has traveled from the lower part of the evening sunlight reflector (morning sunlight position side) to the inner reflection surface of the morning sunlight reflector (evening sunlight position side) In the morning and evening, the reflected light of evening sunlight that has entered the building's daylighting part from the lower part of the morning sunlight reflector to the inner reflection surface of the evening sunlight reflector is incident on the building lighting section. We are trying to improve.

また、朝方太陽光反射板および夕方太陽光反射板を同一平板形状に設定することにより、反射板全体の製造コストの低減化や管理の簡単化を図ることを目的とする。   It is another object of the present invention to reduce the manufacturing cost and simplify the management of the entire reflector by setting the morning sunlight reflector and the evening sunlight reflector to the same flat plate shape.

また、このような高さの変化からなる朝方太陽光反射板,夕方太陽光反射板およびそれが配設される建屋採光部など全体形状のシンメトリー性を確保して、採光装置全体のデザイン化を図ることを目的とする。   In addition, design of the entire daylighting device is ensured by ensuring the symmetry of the overall shape, such as the morning sun light reflector, the evening sun light reflector, and the building daylighting part where it is installed, which consists of such height changes. The purpose is to plan.
