Description
照明器具に関する。
通気部に取り付けられ、前記気密空間部に水を浸入させずに前記通気孔を介して空気を流
通させるように前記通気孔を覆うと共に、所定圧力を超えると前記通気孔から離反して前
記通気孔を開放し、前記気密空間部を外部に連通させる多孔質膜からなるフィルタと;を具備することを特徴とする。
また、光源は、発光ダイオードで構成されており、気密空間部内に発光ダイオード点灯用装置が配設されている構成としたので、光源を発光ダイオードとしたものにおいても、器具内部の急激な圧力上昇に対応することが可能となると共に、長寿命で、かつ省エネ・省メンテナンス形の照明器具を提供することができる。
間部を外部に連通させるようにしたので、簡易な構成で器具内部の急激な圧力上昇に対応
することが可能となり発光ダイオードからなる光源を有する器具の破損を防止することが
できる。
