    • An illumination source is composed of a white LED of a first light source color and an orange LED of a second light source color, so that light is emitted in a color created as a result of mixing the first and second light source colors. The first and second light source colors are represented on the 1931 CIE chromaticity diagram by a first point P1 and a second point P2, respectively. The first point P1 is substantially on the Planckian Locus PL. The second point P2 is at such a position that a line segment L1 connecting the first and second points P1 and P2 is substantially in parallel with a tangent line L3 to the Planckian Locus PL. The tangent line L3 has a point of tangency on a line L2 that is normal to the Planckian Locus PL and passes through the first point P1.
    • 照明源由第一光源颜色的白色LED和第二光源颜色的橙色LED组成,使得以通过混合第一和第二光源颜色产生的颜色发出光。 第一和第二光源颜色分别在1931 CIE色度图上由第一点P 1和第二点P 2表示。 第一点P 1基本上在普朗克轨道PL上。 第二点P 2处于这样的位置,使得连接第一和第二点P 1和P 2的线段L 1基本上与切线L 3平行于普朗克轨迹PL。 切线L 3在与普朗克轨迹PL正交的线L 2上具有相切点,并通过第一点P 1。
