Description
図1に示すように、この発光装置1は、装置の下部をなし絶縁材からなる底部10と、底部10上に互いに離隔するよう配置される金属製の第1リードフレーム11A及び第2リードフレーム11Bと、搭載部としての第1リードフレーム11Aに搭載されるLED素子13と、LED素子13の下面と第1リードフレーム11Aの上面との間に介在するダイボンド材15と、底部10の上方に配置されるLED素子13の側方を包囲するリフレクタ部12と、を備えている。本実施形態においては、底部10及びリフレクタ部12は、例えば、液晶ポリマ(LCP)、ポリフェニレンサルファイド(PPS:熱可塑性プラスチック)、シンジオタクチックポリスチレン(SPS:結晶性ポリスチレン)、ポリフタルアミド(PPA)、ナイロン等の熱可塑性樹脂からなり、各リードフレーム11A,11Bと底部10及びリフレクタ部12とは例えばインジェクション成形を利用して製造される。
次に、発光装置の製造方法について説明する。
図2は、発光装置の製造方法を示し(a)〜(e)はそれぞれ工程説明図である。
次に、発光装置1の動作について説明する。直流電源装置(図示せず)の出力端子の極性と各リードフレーム11A,11Bの極性を合わせて、各リードフレーム11A,11Bに電圧を印加すると、ワイヤ14A,14Bを介してLED素子13に電流が流れ、LED素子13の発光層から青色光が放射される。
本実施の形態によれば、下記の効果を奏する。
(1)この発光装置1によれば、第1リードフレーム11Aに搭載したLED素子13の側面に設けられたダイボンド材15が、LED素子13の側面からの光を遮光する。これにより、各リードフレーム11A,11BにおけるLED素子13の近傍では、LED素子13の発光層から側面へ入射する光が各リードフレーム11A,11Bの表面に直接入射することはない。また、各リードフレーム11A,11Bの間に露出している底部10にも光が直接入射することはない。従って、LED素子13の側方から各リードフレーム11A,11B及び底部10に光が直接入射することがなくなり、比較的短い距離での光の入射を抑止して各リードフレーム11A,11B及び底部10の劣化を抑制し、発光装置1の寿命を延ばすことができる。
