Description
(1)ガラス材による封止部材14で全体を封止したことにより、樹脂封止で問題になった黄変や着色による光の減衰を低減することができる。
(2)LED素子12の周囲に緩衝層13を設けたことにより、封止部材14の封止時に粘度の高いガラス材を介してLED素子12に付与される外力が緩和される。すなわち、緩衝層13の介在によってLED素子12と封止部材14とが直接接触しないので、熱膨張・熱収縮によって生じる応力を緩衝層13によって吸収できる。
(3)緩衝層13を介してLED素子12をガラス封止することによって、LED素子12近傍に生じていたクラックの発生を防止することが可能になる。このような緩衝層13を設ける構成は、封止部材14との接触面積が広くなるラージサイズ(1mm×1mm)のLED素子12において特に有効である。
(4)LED素子12を緩衝層13で包囲することによって、バンプ2の圧潰による電極間の短絡を防ぐことができる。また、緩衝層13がバンプ形状の崩れを抑制することから、ガラス封止によってLED素子12の光軸が傾くことを防げる。
(5)ウェハをスクライブすることによりLED素子12を形成する場合、スクライブされたLED素子12の側面には微細な凹凸が生じている。この凹凸はガラス封止型の発光装置10にとってLED素子12と封止部材14との界面に応力の不均衡部分を形成し、ひいてはマイクロクラックを発生させる要因となる。このような問題に対しては、LED素子12のスクライブ面となる側面に緩衝層21を設けることで、封止部材14の熱収縮時におけるマイクロクラックの発生を防げる。
(1)サブマウント52の下部に放熱を促す放熱部材51を設けたため、LED素子41の点灯に伴う発熱を効率良く外部へ放散でき、ガラス材による封止部材55等の温度上昇に伴う熱膨張・熱収縮の発生を抑制してクラックの発生を防止することができる。
(2)緩衝層54に蛍光体を混合させたことにより、波長変換が行えると共に光の取り出し効率の向上が可能になる。
