Description
本実施の形態によれば、以下の作用、効果を奏する。
(a)蛍光体含有樹脂層7に含有される蛍光体71の含有量を所定の値以上とすることにより蛍光体含有樹脂層7の熱抵抗が低減されることで放熱性能が高くなり、放熱され易くなるため、放熱性に優れたLED光源装置1を提供することができる。
図3は、図2に示す枠部材6の変形例を示すLED光源装置の平面図である。図3に示すように、枠部材16は円形でもよい。
図2に示す構成において、樹脂70に対する蛍光体71の割合を変え、異なる質量比(配合比)毎に蛍光体含有樹脂層7の表面温度を赤外線サーモグラフィにて測定した結果を表1及び図4に示す。表1では、樹脂71の質量を100としたときの蛍光体71の質量を示している。LED素子5の数を121個、全LED素子5への投入電力を190Wとした。
