Abstract
An illumination device includes a light-emitting device and a diffusion member. The light-emitting device has a plurality of light-emitting elements that emit light having a peak wavelength in a wavelength region of 380 to 420 nm, a first phosphor that emits visible light having a peak wavelength in a wavelength region of 560 to 600 nm, a second phosphor that is excited by ultraviolet ray or short-wavelength visible light and emits visible light in complementary color relationship with the visible light emitted by the first phosphor, and a light-transmitting member that covers the plurality of light-emitting elements and contains the first phosphor and the second phosphor dispersed therein. The diffusion member diffuses at least a part of the light emitting from the light-emitting device.
