Abstract
Light irradiation that is suitable for treatment for a relatively small diseased part and is performed almost uniformly and efficiently for the entirety of an affected part even when the affected part is not flat is realized. Light output from a plurality of LED chips includes first wavelength region light whose light-emission intensity peak is in a wavelength range of 380 nm or more and 430 nm or less and second wavelength region light whose light-emission intensity peak is in a wavelength range of more than 430 nm and 635 nm or less, and a group of LED light sources has uniform in-plane intensity of light irradiation.
