Illumination device and light-emitting module

An illumination device comprising:

• a first light source that emits first light having a first peak wavelength which is highest in intensity in a wavelength range from near-ultraviolet to green in an emission spectrum;
• a second light source that emits second light having a second peak wavelength which is highest in intensity in a wavelength range from near-ultraviolet to green in an emission spectrum, the second light illuminating a position identical to a position illuminated by the first light;
• and
• a detection device that detects whether an object is present at a given position, wherein
• the second peak wavelength is shorter than the first peak wavelength, and
• a luminous flux of the first light is decreased and a luminous flux of the second light is increased when the detection device detects that the object is present at the given position, wherein:
• both the first peak wavelength and the second peak wavelength are at least 413 nm and at most 505 nm, and
• F2/F1<(20×λ1−8250)/(20×λ2−8250)
• is satisfied where F1 denotes a peak intensity of the first peak wavelength, λ1 denotes the first peak wavelength, F2 denotes a peak intensity of the second peak wavelength, and λ2 denotes the second peak wavelength.
