Light irradiation device and light emitting module

A light irradiation device (100) is provided with: a first light source (4) that emits first light having a first peak wavelength, the intensity of which is maximum, in a wavelength region from near ultraviolet light to green in an emission spectrum; a second light source (5) that emits second light that has a second peak wavelength with the maximum intensity in the wavelength region from near ultraviolet light to green light in the emission spectrum, and that is irradiated to the same position as the first light; and a detection device (1) that detects whether or not an object is present at a predetermined position, in which the second peak wavelength is shorter than the first peak wavelength, and, when the detection device (1) detects that the object is present at the position, reduces the luminous flux of the first light and increases the luminous flux of the second light. 光照射装置(100)具备：第1光源(4)，发出第1光，该第1光在发射光谱中在从近紫外线到绿色的波长区域中具有强度为最大的第1峰值波长；第2光源(5)，发出第2光，该第2光在发射光谱中在从近紫外线到绿色的波长区域中具有强度为最大的第2峰值波长，并且上述第2光被向与第1光相
