なお、以下の全ての図面においては、各構成要素を見やすくするため、構成要素によって寸法の縮尺を異ならせて示すことがある。
先ず、本発明の第1の実施形態として、例えば図1に示す採光装置1について説明する。なお、図1は、採光装置1の外観を示す斜視図である。また、以下の説明において、採光装置1の位置関係(上下、左右、前後)については、採光装置1の使用時における位置関係(上下、左右、前後)に基づくものとし、特に説明がない限りは、図面においても、採光装置1の位置関係は、紙面に対する位置関係と一致するものとする。
図19Cは、図19A中に示す採光スラット4Fが備える光拡散体33の面内構造を示す斜視図である。
光拡散体33は、概ね短手方向(幅方向)に延在するストライプ状の突起部33aが基材8の長手方向(長さ方向)に並ぶ、いわゆる疑似ストライプ構造を有している。採光スラット4Fには、この疑似ストライプ構造によって異方性散乱特性が付与されている。
次に、本発明の第2の実施形態として、例えば図21に示す採光スラット40を備えた採光装置50について説明する。なお、図21は、採光スラット40の概略構成を示す断面図である。
