Abstract
A light radiation device includes a housing, a substrate provided in the housing, and a light source mounted on the substrate. The light source includes a first light source including at least one first light source to emit first light having a blue wavelength band, a second light source including at least one second light source to emit second light having an ultraviolet wavelength band, and a control unit to control the first light source and the second light source such that the second light source sequentially emits the second light after the first light source emits the first light. A dose of the second light source is less than {right arrow over (1)}/10 of a dose of the first light source.
