Description
本発明において、前記赤色は、ＣＩＥ１９３１色度座標において、（０．６６、０．２３）、（０．４２３、０．３５５）、（０．５，０．５）と色度境界線Ｅで囲まれる範囲の色度である赤色であり、前記それ以外の色の一つは、ＣＩＥ１９３１色度座標において、（０．５，０．５）、（０．４２３、０．３５５）、（０．３４２，０．３１２）、（０．３５２、０．４４）、（０．３７、０．６３）及び色度境界線で囲まれる範囲の色度である黄白色である、光源であってもよい。
In the present invention, the red color is (0.66, 0.23), (0.423, 0.355), (0.5, 0.5) and the chromaticity boundary line E in the CIE1931 chromaticity coordinates. Red is the chromaticity of the enclosed range, and one of the other colors is (0.5, 0.5), (0.423, 0.355), (0 .342, 0.312), (0.352, 0.44), (0.37, 0.63) and a yellow-white chromaticity in the range bounded by the chromaticity boundary, good too.
黄白色ＬＥＤであるＹｗは、図４の色度座標において、（０．５，０．５）、（０．４２３、０．３５５）、（０．３４２，０．３１２）、（０．３５２、０．４４）、（０．３７、０．６３）及び色度境界線Ｅで囲まれる範囲の色度で発光し、一例として（０．４４、０．４７）である。 Yw, which is a yellow-white LED, is (0.5, 0.5), (0.423, 0.355), (0.342, 0.312), (0.352) in the chromaticity coordinates of FIG. , 0.44), (0.37, 0.63) and chromaticity in the range surrounded by the chromaticity boundary line E, for example (0.44, 0.47).
