Abstract

【選択図】図4
Description
[発光装置の構成]
まず、実施の形態1に係る発光装置の構成について図面を用いて説明する。図1は、実施の形態1に係る発光装置の外観斜視図である。図2は、実施の形態1に係る発光装置の平面図である。図3は、実施の形態1に係る発光装置の内部構造を示す平面図である。図4は、図2のIV−IV線における模式断面図である。
近年、LEDチップ12の高輝度化にともない、封止部材13への温度負荷は大きくなっている。したがって、高温環境下における封止部材13の劣化の抑制、すなわち、封止部材13の耐熱性の向上が課題となる。そこで、発明者らは、封止部材13の基材18に添加材19を加えた場合の封止部材13の耐熱性についての試験を行った。図5は、封止部材13の耐熱性についての試験結果を示す第1の図である。
これに対し、例えば、プレート(a)〜プレート(f)は、添加材19として、遷移金属元素の酸化物を含む点がプレートRefと異なる。
また、プレート(g)〜プレート(i)は、添加材19として、遷移金属元素の金属塩である、ジルコニウムの金属石鹸を含む酸化物を含む。プレート(g)〜プレート(i)は、具体的には、ジルコニウムのオクチル酸金属石鹸(日本化学産業社製、ニッカオクチックス ジルコニウム)を含む。
また、プレート(j)及びプレート(k)は、添加材19として、遷移金属元素の有機錯体を含む。プレート(j)及びプレート(k)は、具体的には、ジルコニウムのアセチルアセトン錯体(日本化学産業社製、ナーセム ジルコニウム)を含む。
封止部材13には、遷移金属元素の複合酸化物が添加材19として含まれてもよい。例えば、プレート(l)は、ジルコニウムとイットリウムの複合酸化物((Y2O3)x(ZrO2)1−x:第一稀元素化学工業社製、HSY−3.0)を1.0wt%含む。プレート(l)は、試験開始から336時間の経過でクラックが発生した。したがって、プレート(l)は、プレートRefよりも耐熱性が向上されている。
封止部材13は、遷移金属元素の酸化物、遷移金属元素の金属塩、及び、遷移金属元素の有機錯体の3種類の添加材のうち、少なくとも1種類を含めばよいが、2種類以上を含んでもよい。つまり、封止部材13には、複数種類の添加材19が含まれてもよい。封止部材13には、例えば、遷移金属元素の酸化物と遷移金属元素の金属塩とが含まれてもよい。
また、封止部材13には、例えば、遷移金属元素の酸化物と遷移金属元素の有機錯体とが含まれてもよい。
封止部材13は、添加材の含有量が多いほど、耐熱性が向上すると考えられる。そこで、発明者らは、例えば、遷移金属元素の酸化物を封止部材13にどの程度含有させれば、有意に耐熱性を向上させることができるについて、試験を行った。図6は、封止部材13の耐熱性についての試験結果を示す第2の図である。
以上説明したように、発光装置10は、基板11と、基板11上に配置されたLEDチップ12と、LEDチップ12を封止する封止部材13とを備える。封止部材13は、封止部材13の基材18の劣化を抑制するための添加材19として、遷移金属元素の酸化物を0.05wt%以上含む。LEDチップ12は、発光素子の一例である。
以下、実施の形態2に係る発光装置について説明する。なお、実施の形態2に係る発光装置は、封止部材以外の構成については、実施の形態1に係る発光装置10と同様であるため、封止部材の構造を中心に断面図を用いて説明が行われる。発光装置10と実質的に同一の構成については、同一の符号が付されて説明が省略される。図7は、実施の形態2に係る発光装置の断面図である。なお、図7は、図2のIV−IVにおける断面に対応する断面図である。
以上説明したように、発光装置10aにおいて、添加材には、第一添加材19aと、第一添加材19aよりもLEDチップ12が発する光を吸収しやすい特性を有する第二添加材19bとが含まれる。また、封止部材13cは、LEDチップ12を封止する第一封止層13aと、第一封止層13aの上方に位置する第二封止層13bとを含む。第一封止層13aには、LEDチップ12が発する光によって励起される黄色蛍光体14が含まれる。
次に、実施の形態3に係る照明装置200について、図10及び図11を用いて説明する。図10は、実施の形態3に係る照明装置200の断面図である。図11は、実施の形態3に係る照明装置200及びその周辺部材の外観斜視図である。
以上、実施の形態に係る発光装置、及び、照明装置について説明したが、本発明は、上記実施の形態に限定されるものではない。
