Description
(発光装置100の構成)
第1実施形態に係る発光装置100の構成について、図面を参照しながら説明する。図1は、発光装置100の構成を示す平面図である。図2は、図1のうち発光素子30付近の拡大平面図である。図3は、図2のA−A断面図である。
また、発光素子30からの光を吸収して異なる波長の光を出す蛍光体等の波長変換部材を含有していることが好ましい。このような波長変換部材としては、例えば、酸化物系や硫化物系,窒化物系蛍光体などが挙げられ、発光素子に青色発光する窒化ガリウム系発光素子を用い、青色光を吸収して黄色〜緑色系発光するYAG系、LAG系、緑色発光するSiAlON系や赤色発光するSCASN、CASN系の蛍光体を単独で又は組み合わせて用いることが好ましい。特に、液晶ディスプレイやテレビのバックライト等の表示装置に用いる発光装置は、SiAlON系蛍光体とSCASN蛍光体を組み合わせて用いることが好ましい。また、照明用途としては、YAG系またはLAG系の蛍光体とSCASNまたはCASN蛍光体を組み合わせて用いることが好ましい。
次に、図面を参照しながら、溝部14の構成について説明する。図4は、図1の拡大図である。
(1)第1実施形態に係る発光装置100において、封止樹脂20は、溝部14のうち第1方向と交差する第2方向に延びる第1溝部分141から離間している。
次に、第2実施形態に係る発光装置100Aの構成について、図面を参照しながら説明する。第2実施形態の第1実施形態との相違点は、一対の配線部12に5つの発光素子30が接続されている点である。以下において、当該相違点について主に説明する。
次に、第3実施形態に係る発光装置100Bの構成について、図面を参照しながら説明する。第3実施形態の第1実施形態との相違点は、溝部14の形状が異なっている点と、3以上の端子部13が設けられている点と、それぞれ発光素子30を封止する2個の封止樹脂20が第2方向に並べられている点である。以下において、当該相違点について主に説明する。
本発明は上記の実施形態によって記載したが、この開示の一部をなす論述及び図面はこの発明を限定するものであると理解すべきではない。この開示から当業者には様々な代替実施形態、実施例及び運用技術が明らかとなろう。
