- 扁平状の筐体内に扁平直方体状をなして形成される発光空間から外部に向けて面状に照明光を発する照明装置であって、
列状に配置される複数の発光素子とこれらの発光素子を発光可能に電気接続をする配線とを備えるとともに前記発光空間の扁平直方体状を構成する辺に沿って前記発光空間の両側に収容される一対の発光ユニットと、
前記一対の発光ユニットごとに前記発光ユニットの発光側を前記発光素子の列に沿って覆うように前記筐体に固定され前記複数の発光素子から出射される出射光を拡散する拡散カバーと、を備え、
前記発光空間内における前記発光ユニットの取り付け方向を前記発光ユニットの下方とした場合、
前記拡散カバーは、前記発光ユニットを、前記発光ユニットの発光側である前面と前記発光ユニットの上方である上部とをそれぞれ平板部で囲むとともに、前記前面と前記上部の間には前記前面および前記上部と同様の板厚で内外両側において角を丸めたR部が形成されていることを特徴とする照明装置。 - 前記拡散カバーは、前記前面に加えて発光側の裏側も前記発光素子の列に沿って前記上部に繋がる背面を備え、前記前面、前記背面および前記上部の3方向で前記発光ユニットを囲むように覆うことを特徴とする請求項1記載の照明装置。
- 前記拡散カバーは、前記発光側の裏側には前記上部に繋がる背面を備えることなく、前記前面および前記上部の2方向で前記発光ユニットを囲むように覆うことを特徴とする請求項1記載の照明装置。
