Abstract
Description
図3は、図2のIII-III線における断面図である。
導光部材10は、光源20Aが発する光に対する透光性を有する部材である。光源20Aのピーク波長に対する導光部材10の透過率は、例えば、50%以上が好ましく、70%以上がより好ましい。
光源20Aは、導光部材10の第1孔部h1に配置される。第1孔部h1は、複数の発光部1のそれぞれに配置される。したがって、光源20Aは、複数の発光部1のそれぞれに配置される。
M2[SipAlqMnrFs] (I)
第1透光性部材30は、導光部材10の第1孔部h1における光源20Aの側面と導光部材10との間、及び光源20Aの上に配置されている。第1透光性部材30は、光源20Aの上面及び側面を覆っている。第1透光性部材30は、導光部材10及び光源20Aと接することが好ましい。このようにすることで、光源20Aからの光を導光部材10に導光させやすくなる。
第1光反射部材40は、第1透光性部材30の上に配置される。第1光反射部材40は、第1透光性部材30を介して、光源20Aの上方に配置される。また、第1光反射部材40は、第1透光性部材30及び光源20Aに接していてもよい。また、第1光反射部材40は、接着樹脂を介して、第1透光性部材30及び光源20Aの上方に配置されてもよい。接着樹脂としては、例えば、アクリル樹脂、ポリカーボネート樹脂、環状ポリオレフィン樹脂、ポリエチレンテレフタレート樹脂若しくはポリエステル樹脂等の熱可塑性樹脂、又は、エポキシ樹脂若しくはシリコーン樹脂等の熱硬化性樹脂を用いることができる。また、図2に示すように、第1光反射部材40は、平面視において光源20A及び第1透光性部材30が配置された第1孔部h1と重なる位置に配置される。
支持部材50は、導光部材10及び光源20Aを支持する。導光部材10は、第2面12を支持部材50の上面に対向させて、支持部材50上に配置される。光源20Aは、第1孔部h1において支持部材50上に配置される。
これらの具体例に限定されるものではない。本発明の上述した実施形態を基にして、当業
者が適宜設計変更して実施し得る全ての形態も、本発明の要旨を包含する限り、本発明の
範囲に属する。その他、本発明の思想の範疇において、当業者であれば、各種の変更例及
び修正例に想到し得るものであり、それら変更例及び修正例についても本発明の範囲に属
するものである。
