Title:
紫外線治療器
Document Type and Number:
Japanese Patent JP7125067
Kind Code:
B2
Abstract:
An ultraviolet therapy apparatus having an LED light source can achieve a stable therapeutic effect regardless of the temperature of the LED light source. The ultraviolet therapy apparatus includes an LED light source configured to emit light including ultraviolet light; a controller configured to control lighting of the LED light source; and a measurement unit configured to detect change in a temperature of the LED light source from a reference temperature. The controller includes a calculator configured to calculate a modifying value for modifying an irradiation dose of the ultraviolet light on the basis of change in a degree of effect on a human body caused by change in spectral spectrum of the light due to change in the temperature detected by the measurement unit, and a lighting controller configured to cause the LED light source to emit the light on the basis of the modifying value calculated by the calculator.
