Abstract

　寿命が長く、省電力化を図れるＬＥＤの光を有効に利用し、かつ、照明する商品に応じて、赤味系などの色合いを増加させることができながら、違和感を生じさせないようにＬＥＤを配列した照明装置を提供する。 　断面がほぼ四角形状で、一面に長手方向に沿った開口部１１が形成された筒状体１で、開口部１１と対向する底面１４側に、開口部１１に向けて発光する光を放射するように、複数個の白色光を発光する第１のＬＥＤ２Ｗが筒状体１の長手方向に沿って設けられている。また、少なくとも一方の側壁１２側に、その側壁１２と対向する側壁１３に向けて光を放射するように、複数個の赤色系及び／又は緑色系の光を発光する第２のＬＥＤ２Ｒ、２Ｇが、筒状体１の長手方向に配列して設けられている。さらに、第２のＬＥＤ２Ｒ、２Ｇの発光を制御する制御手段が設けられている。
