Description
EP 1 696 016からは、赤色蛍光体としてカルシン(Calsin)を使用する変換型LEDは公知である。カルシンの概念についてはCaAlSiN窒化物を意味している。
本発明の課題は、窒化物系蛍光体の特性を特別な課題に適切に合わせることを可能にする請求項1の上位概念に記載の蛍光体を提供することである。
窒化物系蛍光体、例えばM2-xCuxSi5N8:Eu(式中、M=(Sr,Ca,Ba))、(この蛍光体の基本形はUS 6 682 663から公知である)及び
Ca1-xCuxAlSiN3:Eu(この蛍光体の基本形はEP 1696016から公知である)並びに
酸窒化物系蛍光体、例えばM1-xCuxSi2N2O2:Eu(式中、M=(Sr,Ca,Ba)),(この蛍光体の基本形はWO 2004/030109から公知である)並びに
更にアルファ−SiAlON類、(この蛍光体の基本形はUS 6 657379から公知である)である。詳細には、式Mp/2Si12-p-qAlp+qOqN16-q:Eu2+(式中、M=Caを単独で又はSr及びMgと組み合わせて、q=0〜2.5及びp=0.5〜3)により表される基本形が重要である。pについて高い値を選択する、つまりp=2〜3であるのが好ましく、qについては相対的に低い値を選択する、つまりq=0〜1であるのが好ましい。純粋なAlの代わりに、特にGaの20mol%までの割合を有するAl,Ga混合物を使用することができる。
次に、本発明を、複数の実施例を用いて詳細に説明する。
図1は、自体公知のようなRGBベースの白色光用の変換型LEDの構造を示す。この光源は、435〜455nmのピーク波長、例えば445nmのピーク発光波長を有する、InGaN型の青色発光するチップ1を備えた半導体コンポーネントであり、この半導体コンポーネントは光不透過性のベースハウジング8中の凹所9の範囲内に埋め込まれている。このチップ1は、ボンディングワイヤ14を介して第1の端子3と接続され、かつ第2の電気端子2とは直接接続されている。この凹所9は注型材料5で充填されていて、この注型材料は主成分としてシリコーン(60〜90質量%)及び蛍光体顔料6(約15〜40質量%)を含有する。第1の蛍光体は、緑色発光するガーネット蛍光体Lu3(Al,Ga)5O12:Ce(LuAGaG)であり、第2の蛍光体としては赤色発光するアルミノニトリドシリケートCa0.99Cu0.01AlSiN3:Eu(0.5%)である。この凹所は、壁部17を有し、この壁部17は、チップ1からの一次放射線及び顔料6からの二次放射線のためのリフレクタとして用いられる。
Ca(1-x)CuxAlSiN3:Eu2+(0.5%)である。
(Ca1-xCux)AlSiN3-2/3xF2x:Eu(0.5%)(式中、x=0.012)
を有する本発明による蛍光体である。
1. 少なくとも1種のカチオンM及び付活剤Dを備え、前記カチオンの割合xがCuで置き換えられていて、Dは一連のEu、Ce、Sm、Yb及びTbからの少なくとも1種の元素である、窒化物系又は酸窒化物系蛍光体の種類からなる蛍光体。

- Mに対するCuの割合が、0.2〜5Mol%の範囲内にあることを特徴とする、請求項1記載の蛍光体。
- 請求項1又は2記載の蛍光体を備えた光源。
- 前記光源は、変換型LED、蛍光灯又は高圧放電ランプであることを特徴とする、請求項3記載の光源。
- 一次放射線を発するチップと、前記チップの前方に配置された蛍光体を有する層とを備え、前記層は、前記チップの一次放射線の少なくとも一部を二次放射線に変換し、その際、請求項1又は2記載の蛍光体の少なくとも1種の蛍光体が使用される、変換型LED。
- 白色を作成するための他の蛍光体として、(Lu,Y,Gd)3(Al,Ga)5O12:Ceを使用することを特徴とする、請求項5記載の変換型LED。
