PROBLEM TO BE SOLVED: To provide an illumination device capable of improving color reproducibility of a viewing object without reference to the way in which the viewing object is viewed.SOLUTION: An illumination device 10 comprises a light source unit 12 and a power supply unit 13. The light source unit 12 includes a blue light source B, a green light source G, and a first red light source R1 and a second red light source R2 having a different peak wavelength. The power supply unit 13 turns on the blue light source B and the green light source G, and switches the outputs of the first red light source R1 and the second red light source R2 to change color rendering properties.SELECTED DRAWING: Figure 1 |
