PROBLEM TO BE SOLVED: To achieve lighting excellent in efficiency by solving directionality and ununiformity resulting from a light-emitting diode, in lighting with a light-emitting diode as a light source.SOLUTION: A phosphor excited by a light source achieves a target color by using a combination of colors to be a complementary color of a light source color. Further, the phosphor is formed separately from the light source while keeping a distance between each other, and, by providing the phosphor itself also with a structure for dispersing or diffusing light, lighting excellent in efficiency and uniformity can be achieved. |
