Claims (3)
- 灯具ハウジング内に設けた複数のLEDと、前記複数のLEDに対向配置され各LEDから出射した光を灯具の正面方向に向けて反射するメインリフレクタと、前記LEDとメインリフレクタの間に介在され、LEDから出射した光をメインリフレクタに向けて拡散して反射するサブリフレクタと、少なくとも1つの段差部を介して連結され前記LEDがそれぞれ少なくとも1つ搭載される複数の平坦部を有する長く延出した基板と、前記基板及びLEDを灯具の正面側に露見させないように覆い隠す意匠部とを備え、当該意匠部は前記基板が延びる方向に長く延出した形状を成し、前記サブリフレクタは、前記LEDから出射した光を前記意匠部の延出方向と垂直な方向に広く拡散して反射するように構成され、前記メインリフレクタは前記灯具ハウジングの正面カバーの湾曲形状に沿って階段状に配置された複数の単位反射面で構成されていることを特徴とする灯具。
- 前記意匠部は正面に反射面を備え、前記メインリフレクタは反射した光の一部を前記意匠部の正面に向けて反射する反射ステップを備えることを特徴とする請求項1に記載の灯具。
- 前記基板は前記意匠部に支持され、前記サブリフレクタは前記基板又は前記意匠部に支持され、前記意匠部は長く延出したその端部において、前記メインリフレクタとの位置決めがなされるよう灯具の固定部に支持されることを特徴とする請求項1または2に記載の灯具。
