Abstract

　本発明のＬＥＤ照明デバイスは、複数種の発光ユニットを備え、当該複数種の発光ユニットから発光される異なる色の可視光を混合して白色光を得るように構成されている。発光ユニットは、ＬＥＤチップと、蛍光体を備える。蛍光体は、ＬＥＤチップから放射される光によって励起され、所定の色の光を発する。ＬＥＤチップは、青色ＬＥＤチップ、紫外ＬＥＤチップ、紫色ＬＥＤチップの群のうちの１つから選択される。前記蛍光体は、それぞれ互いに異なる発光色を発するように構成されている。このようなＬＥＤ照明デバイスは、発する光の色ずれを抑制すると共に、発する光の色再現性の高いＬＥＤ照明デバイスを得ることができる。また、制御回路を備える必要が無いため、低コストである。
