Description
まず、添付の図1および図2は、本発明の一実施の形態である映像投射機能付き照明装置の外観構成を示している。図1は、天井面から吊るすような形態で取り付けられる、所謂、ペンダント型と呼ばれる照明装置に映像投射機能を搭載した映像投射機能付き照明装置を示している。図2は、天井面に取り付けられる、所謂、シーリング型と呼ばれる照明装置に映像投射機能を搭載した映像投射機能付き照明装置を示している。
ここで、本明細書では、プロジェクタを構成する光学ユニット(30)の配置を、以下のように定義する。
光学ユニットの縦置きとは、図4および図5にも示すように、プロジェクタを構成する表示素子32(図3の符号102に対応する)からの光束が、例えば、レンズ等の各種光学素子を含む、所謂、投射光学系34(図3の符号101に対応する)へ入射する際において、当該光束の入射方向、または、当該光束が入射する投射光学系34の光軸が、水平面(図の面に垂直な面)に対して略垂直方向に配置される状態または水平面に平行な方向よりも鉛直方向により近い方向に配置される状態をいう。なお、図4、図5において、z方向が鉛直方向すなわち水平面に垂直な方向である。
光学ユニットの横置きとは、図6および図7にも示すように、プロジェクタを構成する表示素子32(図3の符号102に対応する)からの光束が、例えば、レンズ等の各種光学素子を含む、所謂、投射光学系34(図3の符号101に対応する)へ入射する際において、当該光束の入射方向、または、当該光束が入射する投射光学系34の光軸が、水平面に対して略平行な方向に配置される状態または鉛直方向よりも水平面に平行な方向により近い方向となるように配置される状態をいう。なお、図6、図7において、z方向が鉛直方向すなわち水平面に垂直な方向である。
まず、図8(A)および(B)は、ペンダント型の映像投射機能付き照明装置10の側面断面と下面図である。この例では、光学ユニット30が縦置きレイアウトで配置されている。また、本体である筺体(シェード)11の内側の底面には、複数の半導体発光素子(LED)22を備えた照明用光源20の基板21が取り付けられている。さらに、図の下側の開口面にはこれを覆うように、拡散板12が取り付けられている。
まず、図12(A)および(B)は、シーリング型の映像投射機能付き照明装置10の側面断面と下面図である。この例では、光学ユニット30が横置きレイアウトで配置されている。また、本体である筺体11の内側の底面には、複数の半導体発光素子(LED)22を備えた照明用光源20の基板21を取り付けると共に、図の下側の開口面側にはこれを覆うように、拡散板12が取り付けられ、その内部には、光学ユニット30が、照明光束の略中央部に位置するように配置されている。
なお、以上説明した本発明の映像投射機能付き照明装置の実施例として、以下の変形例を用いてもよい。
