Description
また、上記凹部の開口部において、上記第一の側壁面の一部が上記金属部材から露出され、上記第二の側壁面が上記被覆部材を保持する突出部を有していることが好ましい。
本形態の支持体とは、発光素子を搭載する凹部を有し、光反射壁や導体配線としての金属部材を配置することができる部材である。したがって、本形態の支持体は、アルミ、鉄入り銅を主な材料とするリードフレームや、そのようなリードフレームを樹脂にインサート成型させたパッケージとすることができる。
本形態における発光素子は、発光ダイオードやレーザダイオードなど、発光装置の光源となり得るものである。本形態における支持体には、発光素子とともに、受光素子、およびそれらの半導体素子を過電圧による破壊から守る保護素子(例えば、ツェナーダイオードやコンデンサー)、あるいはそれらを組み合わせたものを搭載することができる。
本形態における被覆部材(「封止部材」と呼ぶこともある。)とは、支持体の凹部内に載置された半導体素子や導電性ワイヤなどを塵芥、水分や外力などから保護する部材である。本被覆部材の材料としては、例えば、シリコーン樹脂、エポキシ樹脂やユリア樹脂が挙げられる。被覆部材は、所望に応じて着色剤、光安定化剤、蛍光物質など種々のものを含有させることもできる。具体的には、発光素子の発光波長や受光波長に応じて、不要な波長をカットする目的で顔料や染料などの着色剤を含有させる。
本形態における保持手段とは、支持体に配された被覆部材が支持体から脱落しないように、その被覆部材を支持体に保持するためのものである。このような保持手段の具体的な形状は、支持体の凹部の内壁に突起、鈎がついているものなどが挙げられる。特に、支持体の凹部の開口方向に、その内径が狭くなるように、凹部の内壁面の一部を突出させた突出部を保持手段として好適に選択することができる。また、このような保持手段は、複数箇所に分設させることもできるし、種々の形状を複数組み合わせることもできる。
