Abstract
【解決手段】LEDチップ3からの光を蛍光体又は波長吸収剤を含む樹脂カバー7を通過させることで発光色を変換して成るLEDランプにおいて、前記樹脂カバー7と発光ダイオードまたは発光ダイオードを封止する封止体の間に蛍光体又は波長吸収剤を含有するバインダー層8が形成されている。
【選択図】図1
Description

(1)LEDチップからの光を蛍光体又は波長吸収剤を含む樹脂カバーを通過させることで発光色を変換して成るLEDランプにおいて、前記樹脂カバーと発光ダイオードまたは発光ダイオードを封止する封止体の間に蛍光体又は波長吸収剤を含有するバインダー層が形成されていることを特徴とするLEDランプ。
(2)前記バインダー層は、シリコーン系接着剤、エポキシ系接着剤及び無機微粒子から選ばれる結着剤並びに蛍光体又は波長吸収剤を含むことを特徴とする上記(1)に記載のLEDランプ。
(3)前記LEDはフリップチップ型発光ダイオードであることを特徴とする上記(1)又は(2)に記載のLEDランプ。
(4)前記樹脂カバーは、透明樹脂に蛍光体又は波長吸収剤を添加してキャップ状に形成されたものであることを特徴とする上記(1)ないし(3)のいずれかに記載のLEDランプ。
(5)前記樹脂カバーの外側に樹脂により形成されたレンズ部を有する上記(1)ないし(4)のいずれかに記載のLEDランプ。
3)、BaMgAl16O27:Eu、(Sr,Ca,Ba)5(PO4)3Cl:Eu、Ba
MgAl16O27:Eu、Mn、Zn2GeO4:Mn、Y2O2S:Eu、3.5MgO・0.5MgF2・GeO2:Mn、La2O2S:Eu、CaS:Eu、LiEuW2O8など、顔料としてはフタロシアニン系、アゾ系、イソインドリノン系、キナクリドン系、レーキ顔料などの有機顔料やコバルトブルー、群青、酸化鉄などの無機顔料、有機蛍光染料としてはペリレン系、ナフタルイミド系、クマリン系、シアニン系、フラビン系、ローダミン系など、擬似顔料としてはプラスチックの粉末を蛍光性のある染料で着色した蛍光顔料などを好適に用いることができる。
せ、色むらを防止する効果があり、また、充填剤としては粒径5μm以上100μm以下の粒子である。これらの材料としては、酸化チタン、酸化アルミニウム、酸化ケイ素、チタン酸バリウム等が使用できる。
KE1935(A/B)、GE東芝シリコーン株式会社製 XE14−062、XE14−907、東レ・ダウ・コーニング・シリコーン株式会社製 SH6103、DX−35−547等の市販品を用いることができる。
図1に示されるように、平坦なリード1、2両方にLEDチップ3の電極面を金バンプ10で直接実装されたフリップチップ型LEDランプを用意した。
プの上部からかぶせたところ、余分な接着剤がLEDチップの下からはみ出し、樹脂カバーとLEDチップの基板との隙間を封止した。接着剤を硬化させこれによって、極めて薄型の白色LEDランプを得ることができた。
図2に示されるように、平坦なリード1上にLEDチップ3が設置され、他方のリード2と金線4による配線が行われているチップ型LEDランプを用意した。
実施例2と同様のチップ型LEDを用意した。
実施例1と同様に、フリップチップ型LEDランプ及びシリコーン樹脂からなる蛍光体入り樹脂カバー7を用意した。
1の割合で混合し、スラリーを調整した。このスラリーをノズルからLEDチップの表面に撒布した後、300℃にて3時間加熱して、蛍光体が分散したシリカからなるバインダー層8が形成された。このバインダー層に蛍光体入りキャップ7を接着剤により被着した
。
実施例2と同様に、LEDランプ及びシリコーンゴムからなる樹脂カバー7を用意した。
図3に示されるように、ヒートシンクに形成されたカップ部内にLEDチップが設置され、他方のリードと金線による配線が行われているチップ型LEDランプを用意した。前記LEDチップは透光性のエポキシ樹脂封止材5によって封止した。
