Abstract
【解決手段】所定の波長の光を発する発光部と、発光部が発した光の一部を吸収し、それよりも長波長の光を発する蛍光体とを含み、発光部の前記所定の波長光と前記蛍光体の前記長波長光とを混合して出射する発光素子である。蛍光体として、一次粒子が、粒径1μm以下の単結晶粒子を用いる。粒径が1μm以下の単結晶粒子は、内部に粒界等の結晶欠陥を発生しにくいため、吸収したエネルギーを結晶欠陥が非輻射的に(熱として)放出することにより発光効率を低下させる現象を抑制することができる。
【選択図】図3
Description
本実施の形態の発光素子は、図1に示したように、基板5と、基板5の中央に配置された青色発光ダイオード2と、青色発光ダイオード2を取り囲むように基板5上に搭載されたケース1と、ケース1内の空間に充填された例えばエポキシ等の樹脂8とを有する。樹脂8には、青色発光ダイオード2が発した青色光の一部を吸収し、黄色光を発する蛍光体10が分散されている。青色発光ダイオード2の発光主波長は、465nmである。基板5は樹脂製であり、基板5上には銅に銀メッキ処理を施すことにより形成された電極6,7が配置されている。電極6,7は、金線3,4により青色発光ダイオード2の電極端子と接合されている。ケース1は、反射率の高い樹脂で形成されており、青色発光ダイオード2が発した青色光及び蛍光体10が発した黄色光を反射し、樹脂8の上面から外部に出射するように構成されている。これにより、樹脂8の上面からは青色光と黄色光とが混合された白色光が発せられる。蛍光体10は、(Y、Gd)3Al5O12:Ceを用いている。これは、一般にYAG(ヤグ)として知られるY3Al5O12結晶のY原子の一部をGdで置換した構造であり、微量のCeがドープされたものである。
予めアルミ板に銀メッキ処理により電極6,7が形成された基板6に、反射率の高い樹脂で形成されたケース1を取り付け、ケース1の中心に発光主波長465nmの青色発光ダイオード2を固定して、金線3,4により電極6,7に接合した。
