Description
すなわち、本発明の第1の局面による照明装置は、LEDとレンズを含む光源と、被照射体と、カバーと、を有する照明装置であって、光源はカバーの内側に配置され、光源からの光はカバーの縁と被照射体の間を通り、カバーの縁は、被照射体に対する光源からの光の照射範囲を規定し、レンズは、被照射体に近い部分の光透過率が、他の部分の光透過率より高い。
すなわち、本発明の第2の局面によれば、上記の照明装置において、レンズには光透過率調整用の粒子が分散されている。
本発明の第3の局面によれば、上記の照明装置において、レンズの光透過率は、レンズの厚さにより制御される。
本発明の第4の局面によれば、上記の照明装置において、レンズの表面は多段状に形成される。
本発明の第5の局面によれば、上記の照明装置において、レンズの表面は傾斜状に形成される。
比較例として、図7に、レンズ体20’のレンズ21’が一定の厚さ(例えば、1.5mm)を有するランプユニット10’を示す。図8は、メータクラスタ1に対して比較例のランプユニット10’を適用した場合のランプユニット10’による間接照明の状態を説明するための拡大図であり、第1実施形態の図2に対応する図である。図9は図8のメータクラスタ1の一点鎖線IX−IXにおける断面を矢印の方向に見た断面図である。
レンズ21のうち、被照射体としての基体3に近い部分の光透過率を比較的高くする方法は、上記実施形態のようにレンズ21を第1および第2のレンズ部分211、212の二段構造とする方法に限らない。例えば、図6(A)に示すランプユニット10Aのレンズ体20Aのように、レンズ21Aの表面が傾斜する平面状であって、レンズ21Aの厚さが基体3より遠い側から近い側へ向かって連続的に減少するものを用いてもよい。あるいは、図6(B)に示すランプユニット10Bのレンズ体20Bのように、レンズ21Bの表面が曲面状であって、レンズ21Bの厚さが基体3より遠い側から近い側へ向かって連続的に薄くなるものを用いてもよい。また、図6(C)に示すランプユニット10Cのレンズ体20Cのように、レンズ21が平坦な第1、第2、第3のレンズ部分211C、212C、213Cの三段状のレンズ部分を有するものや、それ以上の段数のレンズ部分を有するものであってもよい。更には、これらの構成を組み合わせたものであってもよい。
