PROBLEM TO BE SOLVED: To provide a color-tunable LED luminaire capable of readily changing irradiation colors according to an irradiation object while eliminating the necessity of stocking a plurality of fluorescent lamps, and also having few problems due to heat generation.SOLUTION: The color-tunable LED luminaire includes a plurality of LED rows having different irradiation colors, and a volume-type variable resistor capable of changing a value of resistance is provided for each of the LED rows. The LED rows preferably have three rows, among which one may be a blue LED row, one may be a red LED row and the other may be a green LED row.COPYRIGHT: (C)2012,JPO&INPIT【課題】複数の蛍光灯をストックしておく必要なく、照射対象物に応じて手軽に照射色を変更することができ、かつ、発熱による問題も少ない色調式LED照明具を提供する。【解決手段】色調式LED照明具は、色の異なる複数のLED列を備え、各LED列毎に、抵抗値を変更することができるボリューム式可変抵抗器を設けている。LED列は、好ましくは3列あり、一つが青色LED列であり、一つが赤色LED列であり、もう一つが緑色LED列であり得る。【選択図】図1
