Abstract
An ultraviolet irradiation device includes a light-emitting element, a temperature control element, and a control circuit. The light-emitting element is configured to emit an ultraviolet light. The temperature control element is configured to control a temperature of the light-emitting element. The control circuit is configured to control the temperature control element based on a voltage of the light-emitting element so as to control a peak wavelength of the ultraviolet light.
