PHOSPHOR CONVERTED LIGHT EMITTING DIODE, LAMP AND LUMINAIRE

To provide a phosphor converted light emitting diode (LED), a lamp and a luminaire.SOLUTION: A phosphor converted LED 160 comprises an LED 102, a first luminescent material 166, a second luminescent material 164 and a third luminescent material 162. The LED emits a first spectral distribution having a first peak wavelength in the blue spectral range. The first luminescent material absorbs a portion of the light of the first spectral distribution and converts the absorbed light into light of a second spectral distribution that has a second peak wavelength in the green spectral range. The second luminescent material absorbs a portion of the light of the first spectral distribution and/or the second spectral distribution, and converts the absorbed light into light of a third spectral distribution that has a third spectral width and has a third peak wavelength. The third luminescent material absorbs a portion of the light of the first spectral distribution, the second spectral distribution and the third spectral distribution, and converts the absorbed light into light of a fourth spectral distribution that has a fourth spectral width and has a fourth peak wavelength. The third peak wavelength and the fourth peak wavelength are in the orange/red spectral range.SELECTED DRAWING: Figure 1c 【課題】燐光体変換発光ダイオード（ＬＥＤ）、ランプ、及び照明器具を供する。【解決手段】燐光体変換ＬＥＤ１６０は、ＬＥＤ１０２と第１発光材料１６６と第２発光材料１６４と第３発光材料１６２とを含む。ＬＥＤは、青色スペクトル内に第１ピーク波長を有する第１スペクトル分布を発光する。第１発光材料は、第１スペクトル分布の光の一部を吸収し、緑色スペクトル内に第２ピーク波長を有する第２スペクトル分布の光へ変換する。第２発光材料は、第１スペクトル分布、第２スペクトル分布の光の一部を吸収し、第３スペクトル幅を有し、第３ピーク波長を有する第３スペクトル分布の光へ変換する。第３発光材料は、第１スペクトル分布、第２スペクトル分布、第３スペクトル分布の光の一部を吸収し、第４スペクトル幅を有し、第４ピーク波長を有する第４スペクトル分布の光へ変換する。第３ピーク波長と第４ピーク波長は、オレンジ／赤色スペクトル内である。【選択図】図１ｃ
