Abstract

Abstract Translated from Japanese (57)【要約】 【課題】 発光ダイオード素子単体では発光させること が困難な白色その他の微妙な色相の光を発光させるよう にする。 【解決手段】 発光ダイオード素子4を平面状に実装し てなる発光器本体3aと、発光器本体3aにおいて発光 ダイオード素子4の周囲に装着される蛍光材入りの(第 1の)ドーム状キャップ部材6とを設ける。この場合に は、発光ダイオード素子4から出た光のうちの一部はド ーム状キャップ部材6を透過し、残りの光はドーム状キ ャップ部材6内の蛍光材に入射して、蛍光材が蛍光を発 する。このため、ドーム状キャップ部材6を出射する光 の色相は、透過光の色光と蛍光色との混合色になり、発 光ダイオード素子4と蛍光材を適宜選択することによ り、発光ダイオード素子単体では発光させることが困難 な白色その他の微妙な色相の光を発光できるようにな る。 (57) [Problem] To emit light of white or other delicate hue, which is difficult to emit light with a light emitting diode element alone. SOLUTION: A light emitting device main body 3a in which a light emitting diode element 4 is mounted in a planar shape, and a (first) dome-shaped cap member containing a fluorescent material mounted around the light emitting diode element 4 in the light emitting diode main body 3a. 6 is provided. In this case, a part of the light emitted from the light emitting diode element 4 passes through the dome-shaped cap member 6, and the remaining light enters the fluorescent material in the dome-shaped cap member 6, and the fluorescent material Emits. For this reason, the hue of the light emitted from the dome-shaped cap member 6 is a mixed color of the transmitted light and the fluorescent color. By appropriately selecting the light emitting diode element 4 and the fluorescent material, the light emitting diode element alone emits light. It becomes possible to emit light of white or other subtle hue that is difficult to make.
