実施例2は、上述した映像投射機能付き照明装置10の一部、即ち、本体(シェード)11内部の照明用光源20、小型プロジェクタ30、電源部80について、天井または壁との相対的位置が不変の固定部材である保持具40との相対的位置が可変となっている。他方、本体(シェード)11は、当該保持具40に対して相対位置を固定した構造を有している。図8には、本実施例2になる映像投射機能付き照明装置10を、その内部構成をも含め、(A)の上面図、(B)の側面図、(C)の底面図により示す。なお、その内容も基本的には上記図2と同様の部分が多い。よって、ここでは図2と同様の部分については詳細な説明は省略し、その特徴となる回転機構について、以下に図9および図8を参照しながら説明する。
実施例3は、上述した表示素子と投射光学系との相対位置可変機能を利用することにより、投射される映像の位置をより大きな範囲で移動することを可能とするものである。本実施例3では、上述した映像投射機能付き照明装置10において、小型プロジェクタ30のうち投射光学系である投射レンズ32の天井または壁との相対的位置を固定し、小型プロジェクタ30のうち表示素子を含む部分が移動及び回転可能な構造である。これにより、投射光学系の光軸と表示素子の相対的位置関係を変更することが可能である。
続いて、上述した表示素子と投射光学系との相対位置可変機能を利用することによって投射映像の位置を移動可能とする他の例として、実施例4になる映像投射機能付き照明装置10について、図15~図17等を参照しながら以下に詳細に説明する。本実施例4では、図15の(A)の上面図、(B)の側面図、(C)の底面図にも示すように、本体(シェード)11の内部には、照明用光源20や電源部80などと共に、小型プロジェクタ30のうち表示素子を含む部分が固定されて配置されているが、小型プロジェクタ30の投射レンズ32の位置を移動及び調整可能とするものである。その他の構成部品は本体(シェード)11に固定された構造として構わない。そのため、その内部構成も基本的には上記図2と同様の部分が多い。よって、ここでは図2と同様の部分については詳細な説明は省略し、その特徴となる小型プロジェクタ30と投射レンズ32の相対位置の移動機構について、以下に図16および図15を参照しながら説明する。
上述した実施例、特に、実施例4では、本体(シェード)11内に配置される小型プロジェクタ30は固定されているものとして説明した。しかしながら、実施例4に係る映像投射機能付き照明装置において、更に、小型プロジェクタ30を含む本体(シェード)11全体を、Z軸を中心に回転可能とする機構を設ければ、実施例4で説明した映像の移動に加えて映像を回転することも可能になる。以下、実施例5の映像投射機能付き照明装置について図18及び図19を参照しながら説明する。
