摘要:
An object of the present invention is to provide a photodynamic therapy light irradiation device for irradiating two kinds of light in different wavelength ranges to an irradiated surface, the device being capable of irradiating the light with uniform illuminance to the irradiated surface even having an uneven shape and obtaining a spectral distribution of high uniformity on the entire irradiated surface.A photodynamic therapy light irradiation device of the present invention is characterized by including: a light source unit having one or more LED elements that emit first light having a peak wavelength within a range of wavelengths of not shorter than 400 nm to not longer than 420 nm disposed on a flexible substrate; and a fluorescent plate configured to transmit a part of the first light from the light source unit, and to convert another part thereof into second light having a wavelength of not shorter than 500 nm to not longer than 520 nm and thereby emit the second light.
