摘要：
A phototherapy device includes a light source module configured to emit therapeutic light to an affected area of a skin. The light source module includes a plurality of LED elements to emit light having a peak wavelength in a range of 365 nm±5 nm, and having a wavelength equal to or shorter than 350 nm. The light source module also includes a light outlet window to which the light emitted from the LED elements is incident and through which the therapeutic light exits. The light source module also includes a filter configured to substantially shield light having a wavelength equal to or shorter than 350 nm when the light emitted from the LED elements passes through the filter.
