Description
照明器具1は、発光装置2を一方向に沿って複数個配列したものである。照明器具1は、筐体3の内部に、複数の発光装置2を直線状に配置された構成を有している。照明器具1は、天井または壁等の室内に直接取り付けるか、あるいは、屋外にて使用するものである。そして、照明器具1から発せられる光は、室内または屋外を照らすことができる。
ここで、本実施形態に係る発光装置2に用いられる発光素子8について説明する。図4は、発光素子8の概観斜視図であって、一部内部が透過している状態を示している。図5は、図4のY−Y’に沿った発光素子8の断面図である。
本実施形態の発光装置2は、発光素子8を下面に実装した実装基板9と、実装基板9の下面に発光素子8を取り囲むように設けられるとともに、一方の縁10aが実装基板9と接続され、他方の縁10bの実装基板9に対する高さ位置が実装基板9に対する発光素子8の高さ位置よりも間が空いて配置されたリフレクター10と、リフレクター10の他方の縁10bの内壁面に設けられた光拡散体11と、を備えている。
ここで、図2に示す照明器具の製造方法を説明する。
